Steering assist reduced message followed by check engine light came on and temperature gauge not moving from cold. Immediately took it to the dealership Hiley Chevrolet in Rockwall, TX. After $250 for diagnostic, failed thermostat is the cause and $1216 repair cost. Known issue that Chevrolet issued special coverage for 2021 Blazers, but none for 2020. My vehicle has a little more than 51,970 miles. Same vehicle just had battery replaced two weeks ago at same dealership and no other issues showed up during diagnostic then.

Received Error code P0021 "A" camshaft position timing is over-advanced in Bank 2 of the engine" Occured 3 times before taking it into dealer. Chevrolet dealership agreed and it was covered under powertrain warranty.

Frequently when shutting off my Blazer, I will get an alert that the vehicle is not in park. I have to squeeze and jiggle the shifter in order to get the alert to go away. On several occasions, when I have turned the engine on and back off again without ever touch the gear shifter, I will get the same alert that the vehicle is not in park. If the issue is not just the sensor/switch, this could mean that the transmission could potentially fall out of park and the vehicle start to roll on its own with no one inside.

Shifter Assembly and Harness When putting vehicle into "Park" and then shutting off the vehicle a warning message would appear that the car had to be placed into park and a beeper would sound. Never sure if vehicle is actually in park. Have to restart the vehicle, move the parking gear from park, then back into park until message does not appear. This issue was a recall for the 2013-2019 Chevy Blazers, but was not recalled for the 2020 Blazer, although it appears that this is still an issue. Had issue repaired by paying for the replacement of this shifter assembly.

I took it back to used dealer who also agreed there is a leak but couldn't detect it. They sent me to Chevy Dealer. It has been 3 months now and dealer states the transmission has a seal leak. It seems like a similar recall on same year and model, however my vehicle is not listed as a recall. Why isn't there one?

After the vehicle has been put into parked and attempted to shut off, a message displays “Action Required Shift To Park”. Although the vehicle is in parked there is some kind of sensor that is not reading it is in park. Vehicle first started doing this when parked on an incline but frequently happens since the first occurrence. One temporary solution is to shift into different gear or shake the gear shift.

On multiple occasions, my 2020 Chevrolet Blazer RS has failed to recognize when it is shifted into the "Park" gear. When this occurs, a "Shift to Park" message appears on the dashboard, and the vehicle's electronics will not shut down, preventing me from turning off and locking the vehicle. This defect presents several critical safety hazards: Inability to Secure Vehicle: The engine/electronics remain active, preventing the vehicle from being turned off and secured. This could drain the battery, leaving me stranded, or make the vehicle a target for theft. Driver Distraction: The warning message has appeared randomly while the vehicle is in motion, creating a serious and unexpected distraction for the driver. Potential Rollaway Risk: This failure in the system that confirms the vehicle is in Park could lead a driver to exit the vehicle believing it is secure when it is not, creating a potential for a vehicle rollaway. On 05/02/2024, I had the vehicle serviced for this specific issue. The dealer replaced the transmission shifter and control assembly at my expense, refusing to cover it under the powertrain warranty. The manufacturer (General Motors) is aware of this widespread defect and has issued Technical Service Bulletins (TSB #MC-10199243-9999) about it, yet they fail to treat it as the serious safety issue it is. This component failure should be investigated for a formal safety recall before it leads to an accident, injury, or death.

My vehicle has been throwing an error code related to the thermostat. The temperature gauge will remain on C resulting in the fan running loudly, the air conditioner not cooling the cabin of the vehicle well, and a message displaying "steering assist is reduced drive with care". When I check the fluid levels everything is fine without issue. I'm VERY frustrated and want to get rid of my Blazer ASAP.

I am getting the message "Shift to Park" displayed while vehicle in park after turning the vehicle off. Looking online, it seems to be a common issue with Blazers as well as other GM vehicles. I found online that "the cause of the condition may be that the park switch in the transmission control (shifter) assembly is not pulling the BCM signal low to electronically show that the vehicle is in the Park position." If this is such a common issue on similar vehicle to mine since 2018 it appears, why is this not a Recall already?!

"Steering Assist Reduced” warning message appears on dashboard display and temperature gauge stuck on cold on the dashboard display. I understand this such a common issue with the 2019 and 2020 Blazer that General Motors has issued Technical Service Bulletins but refuses to repair these vehicles for free. This is unacceptable! Issue a mandatory recall therefore GM must perform the repairs for free.

Oct 13, 2025

The blazer's check engine light came on and I had it scanned. The code was PO128 indicating that the engine coolant temperature is consistently below the thermostat regulating temperature. We are also getting a message on the vehicle that states the steering assist is reduced, drive with care. The car is also blowing hot air when the AC is on, the temperature gauge is staying at the lowest setting and the fans are running full blast. This seems to be a very common problem with the Chevrolet Blazer.

Jun 06, 2025

Vehicle gives warning that steering assist is disabled. I should drive carefully. Also cooling fans run on high and temp gauge reads zero. P0128 I'd code given by computer. When code is cleared vehicle returns to normal operation. I read many, many people have this same problem with no clear correction. Many have replaced thermostat, temp sensors, and problem returns. Sounds like defective wiring to me and if it impacts steering should be an OEM problem to remedy

IN 2 OCCASIONS MY VEHICLE CAME TO A COMPLETE STOP AND TURNED OFF ON ME. I WAS THINKING IT WAS A SAFETY FEATURE BUT AFTER THE 2ND TIME I WAS CONCERNED.

TOOK IT TO DEALERSHIP AND THEY FOUND NOTHING WRONG, ACCORDING TO THEM TRUCK WAS PERFECTLY FINE.

I am experiencing the well known "shift to park message" while the shifter is in park. I cannot turn the vehicle off and I am worried the battery will die. This is a well documented issue with this vehicle, and several other models outlined in TSB 19-NA-206, for years and yet they refuse to issue a recall to repair the faulty design or component . I have reached out to them via email, but no action has been taken, see email below. ------------------------------------------------------------------------------------- GM Customer Care, I am writing to request assistance regarding an issue with my 2020 Chevy Blazer VIN# [XXX] . This is my fourth new GM vehicle, and while it is currently outside the 36-month warranty period, the vehicle has only 18,800 miles on it. Recently, the vehicle began displaying a persistent "Shift to Park" message on the Driver Information Center, despite the gearshift being in the Park position. As a result, the vehicle remains in the ON position and cannot be turned off. This is a well-documented issue affecting several GM models, including the Blazer, Acadia, Malibu, Traverse, and Volt. For reference, please see TSB 19-NA-206 attached. Repair costs for this issue appear to vary widely, sometimes exceeding $1,000 depending on location and dealership. Given that this appears to be a known design or component issue, I do not believe this should be an out-of-pocket expense for the customer. As a long-time GM customer, I respectfully request that GM cover the cost of this repair. I am disappointed that there has been no proactive recall or service campaign, especially considering the volume of customer complaints reported online. Thank you for your time and attention. I look forward to your response and hope GM will stand behind its products in this matter. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In March 2025 a Steering assist reduced warning came on briefly. Over the next several weeks intermittent. April 2025 Engine warning light came on. 4-14-25 Went to ToddWenzel Chevrolet for diagnosis to be told the Thermostat needs to be changed and due to a small amount of crystallization on the radiator that as well. I had just had oil changed and fluid levels topped off that morning at Parkway express who did not identify concerns. 4-15-25 brought to Parker Brake who diagnosed and identified there was a glitch that prompted the warning and they can tell that fired when not driving, temp 125Degrees. "it may have been parked cooling down". They noted not need for additional service. Thermostat fine and no evidence of radiator leak. They cleared codes/engine warning. After about a week experiencing intermittent assist reduced warning again. I am understanding that this is a known problem w/ these Blazers and changing thermostat for many does not work. Where does this leave me? GM needs to help with the cost and figuring this out. I am concerned about sudden failure of something while driving that could be unsafe for myself/others.

On Saturday, March 8, 2025 I was crossing a busy intersection when my car shut off completely and accelerated into oncoming traffic almost causing a collision or fatality. My brakes locked and steering wheel locked. I had to put the emergency brake on in order for the car to come to a stop. We got out of the car in the middle of the street and ran for safety. Scariest experience I’ve ever been in especially with my family in the car!!

The contact owns a 2020 Chevrolet Blazer. The contact stated that the transmission was slipping while driving in the lower gears. The contact stated that the message “Reduced Steering - Drive with Caution” was displayed. The vehicle was taken to the dealer but was not diagnosed or repaired. The contact stated that the failure persisted, and the vehicle became inoperable. The manufacturer was informed of the failure and opened a case. The failure mileage was approximately 50,000.

May 20, 2025

At around 55,000 miles my Blazer began to show error codes for “Steering Assist Reduced” and “ESC”. After 60,000 it began to intermittently populate the Check Engine Light paired with the "Steering Assist Reduced" message. Then, the engine fan would turn on high, auto-start when breaking would disable, and the steering would become more stiff. Finally, I was able to get a scan on the code and found out that it was my thermostat. After taking it to my local Chevy dealer I was quoted $1100 to repair. When I called my local mechanic I was told they could fix it for cheaper, but they were unable to find an OEM thermostat in stock which usually means there's a widespread issue with that part. Upon further research, I've found a plethora of complaints online where others with Chevy vehicles are experiencing the same issue. This causes: -Greater fuel consumption -Risk for the engine to overheat -Stiffened steering which could cause accidents

My shift to park comes on although the vehicle is parked My steering is reduced came on today this is a problem in mutiple forms in regards to chevy blazers

Aug 21, 2024

As I was driving, my engine coolant temperature gauge went from normal level down all the way pegged to C. Message appears on my dashboard "Steering Assist is Reduced. Drive with Care". Also, radiator fan continuously runs as if the air conditioner was turned on, which it was not. After searching the internet and confirmed by dealerships and the shop I had my car repaired, this same issue with the coolant temp sensor and thermostat is a very common occurrence on these generation Chevy Blazers. It just amazes me and disappoints me that this type of failure on a car happens as soon as 70,000 miles. Should last for much much longer before this type of failure happens.

Where do I start. Spring of 2024 I believe, less than 55,000 miles, my transmission went out. No warning. I just went out to my vehicle to go to work and when I put it into reverse, my vehicle make a awful noise, jerked forward almost going into my garage door, then wouldn't move.. I put it back in park, tried to put into reverse again and it wouldn't go. It was stuck in park. Had to get it towed to the dealership where they advised me the transmission went out. It was covered under the drivetrain warranty, but the GM warranty doesn't cover rental. It took almost 4 weeks for GM to approve for a new transmission due to parts being on back order to rebuild my transmission. Several months later, I was driving down the road when the ESC light and then it said "shift to neutral & press start" and I lost power. I coasted into a parking lot, got it fired up, but had no air conditioning (of course it was summer). Took it to the dealer and they said my radiator and A/C Compressor had to be replaced. Luckily my extended warranty covered the $5000 repair. Now 4 months later I got "steering assist reduced, drive with care" with codes. Took to shop and the codes basically was the temp was to low, but the shop couldn't find anything wrong. Cleared the codes and so far so good, but now my ESC light pops on once a week again. I don't even have 60,000 miles on my vehicle.

Steering assist reduced warning came on as I was driving. Electric steering module has gone bad.Temp gage and AC stopped working as well. No accident yet but this is a KNOWN SAFETY DEFECT that needs to have a recall. The steering wheel could lock up. Force GM to recall this vechile before people die!!

Apr 04, 2024

My 2020 Chevy Blazer began demonstrating possible problems with the transmission in November 2021 which have continued to date. The RPMs will rapidly increase and the car will feel as if it is jolting forward. If driving below 20 mphs, when I try to accelerate to a higher speed, the car will drag and then skip forward. I have videos showing this and have taken it to the dealership on two occasions but it couldn't be replicated and no codes show during diagnositics. The car is currently being repaired (at the dealership since 3/18/22) due to 3 separate concerns that are co-occuring which seems quite strange to me. The thermostat has gone bad, causing my check engine light to come on while driving (and having to have it towed). The car is also not recognize my remote key to operate the car. I am also getting "steering assist reduced" notifications while driving. I had the battery replaced 3 weeks ago because that was felt to be the cause of the steering assist notice, but after 1 week the notices started occurring again. I will also occasionally get "ECM" notices while driving. I don't see how all of this could be happening at the same time and it not be indicative of a more major Powertrain issue. I do not feel safe driving the car, even when these separate issues are repaired because I am fearful of the core, underlying cause.

This is for all four of the Continental Crosscontact LX Sport tires, size P 235/ 85 R18 with about 22,800 miles on them. These were the original tires that came with our 2020 Chevrolet Blazer. While driving on dry roads the car felt like it was on marbles, wanting to wiggle on the road. We took it to our locale Chevy dealership, they took a short look at the tires, and told us to have them replaced very soon. I started do research on new tires and also found out that Continental had put out a Voluntary tire recall there, this was for 93,959 of their passenger tires. But only certain mold dates and serial numbers were on this list. We had only one of our four tires on their list. All four tires had the same wear pattern, the outside tread of each tire had worn down to approximately 0.150", with the inside of tire tread at approximately 0.205". Probably near normal wear for a 22,800 mile tire. To me the malfunction was with the outside tire breaking down and becoming weak, causing the excessive wear and unstable driving experience, putting the car at risk of accident and all passengers in it. We replaced them with Goodyear Maxlife tires. One of the tires with the serial #[XXX] was on the recall list, Continental paid for it to be returned to them, and verified that it was on recall, they are to pay us for 1/2 of its life. Contacting them again, I told them again that all the tires had the same wear pattern. They then asked for the other 3 remaining tires to inspect. After they inspected the other 3 tires they have denied any other claims of defects on those tires. I do not have any tire to show you now, but Continental's records should show the tire wear as I have stated. Of the 3 tires, 2 of the tires not recalled were A3LM WD30 dated 08-20, serial #[XXX] and [XXX], and the third tire A3LM WD30 dated 12-20 with serial #[XXX].

My safety and others safety is put at risk due to loss of tread causing traction to be lost on damp or wet roadways. The problem has been confirmed by the dealership service department.

New 2020 Chevy Blazer AWD Premier with OEM Continental CrossContact LX Sport tires in size 265/45R21. Car has 18,000 miles on it and tires have been rotated and inflated correctly. All 4 tires have tread depth near 2/32 and need to be replaced per tire shop. Come to find out this Continental brand of tires has no treadlife warranty at all so they don't even believe in their product. How can Chevy and Continental be allowed to put this tire on new cars to rip off the consumer. I'm going to have to buy 4 new tires on a car that has 18,000 miles on it. This should not be happening. It's also a safety concern for others on the road that aren't aware they need to check their tire tread depth so soon with these tires.

Thermostat gauge isnt moving along side a message saying "Steering assis is reduced drive with care"

Oct 31, 2025

Component/System Involved: The electric power steering system in my 2020 Chevy Blazer is malfunctioning. A warning appears on the dashboard: “Steering Assist is Reduced – Drive with Care.” When this happens, steering becomes very stiff and difficult. The issue is ongoing, and the component is available for inspection if requested. Safety Risk: This creates a serious safety hazard. The sudden loss of steering assist makes it hard to turn the wheel, especially at low speeds or when maneuvering. It puts me and others at risk, especially if it happens in traffic or while turning. Problem Confirmed by Dealer: No, the issue has not yet been inspected or confirmed by a dealer or service center. Inspection History: The vehicle has not been inspected by a dealership, manufacturer, police, or insurance. Warning Signs: The only warning is the “Steering Assist is Reduced – Drive with Care” message, which appears randomly—sometimes at startup, sometimes while driving. The issue began around 10/15/2024 and continues to be an on going issue.

Also attempted to disconnect the battery for several minutes which would in turn clear the message and all would be working fine. This has been done multiple times and is at random when the message and AC stop working

Shift to park message began appearing even after the shifter knob was in park. I cannot turn the vehicle off and it rolled backwards due to the vehicle not recognizing it was in park. This has now cost $700 to repair when its been a known issue with these vehicles for over 6 years and yet they refuse to issue a recall. This is dangerous and disgusting practice for a vehicle manufacturer to avoid keeping their customers safe.

My vehicle lost complete power while I was sitting at red light. The dashboard went completely out and pop back on stating to put the vehicle in park and push the brake to start. After following those instructions the vehicle failed to start and I left disability until OnStar notified MPD to assist. While waiting for assistance I was almost hit 3 times. When MPD arrived on the scene they were able to push the vehicle out of traffic. After my vehicle arrived at the shop I was told the power failure was caused by the malfunction of the DC/DC CONVERTER Output voltage. I see a bulletin was put out but a recall was my made available. I feel this is a major issue due to the vehicle losing power.

To whom it may concern, I purchased a new 2020 Chevy Blazer from the dealership five years ago. Since then I have had to replace my battery twice, radiator and now the thermostat all of which have been done at the dealership. The car and all receipts of the repairs are available for inspection if requested. This most recent mechanical issue with the thermostat included the following; fans blowing on high, no AC, check engine light, steering assist reduced message, and temp gauge on C. The car was immediately (same day) taken to the dealership for investigation. Upon inspecting the car the mechanic found the thermostat sticking open and indicated that it would need to be replaced as it was unsafe to drive. A total cost of $1400. It seemed odd that my car is only 5 years old with 75k miles and needing to have the thermostat replaced so I started researching this issue further. I found several complaints on the www.chevyblazer.org forum from other 2020 Chevy Blazer owners with the same mechanical issue. There is one comment on the forum from a mechanic stating that this issue is caused by a faulty wire harness and will continue to cause similar issues until the wiring is fixed. You can find those comments in the forum on www.chevyblazer.org This continues to be an ongoing issue with this make and model of Blazer with no consistent fix from the dealer. I believe my previous battery and radiator issues are all related. I am reaching out to you for assistance and/or guidance to help get this mechanical issue reported as a recall by the dealer and properly fixed at dealer cost. I am happy to provide any additional support you may need to research this further. Thank you in advance.

2020 Chevy Blazer - Shift to Park while Gear is already in Park: While putting the gear in park, the warning chime to shift it into park is initiated. It has happened 3 to 4 times in the past three days. I took the vehicle to the Local Chevy Dealership. The Service Team/Dept. diagnosed that the Transmission Shifter Unit Assembly must be replaced. The 2019 Chevy Blazer had these issues which prompted a TSB/Recall however it wasn't extended to the 2020-year models and Chevy Dealership refused to include it as a warranted repair which just passed 44,000 miles. This is a safety issue, and it should be replaced without additional cost to customer as this issue was already identified as a safety concern in 2019, however Chevy does not want to identify the issue as a covered repair per the manufactures warranty.

Component/System Involved: The shift-to-park sensor in my 2020 Chevy Blazer is malfunctioning. After shifting into park, the vehicle does not detect it and displays a “Shift to Park” message. The issue is ongoing, and the component is available for inspection if needed. Safety Risk: The vehicle cannot be fully shut off or locked, increasing the risk of battery drain or unintended movement. This poses a safety risk if the vehicle is left in public or on an incline. Inspection History: The vehicle has not been inspected Warning Signs: The “Shift to Park” message appears when trying to turn off the vehicle, despite the gear being in park. This started around Fall 2024 and has occurred regularly since.

I backed my vehicle out of the garage and put it in park and stepped out of the Driver's door. I was going to put my son in his car seat in the rear seat when the vehicle started moving backwards and the opened driver's door knocked us down. I was able to push my son out of the way, but the vehicle continued and the front left tire rolled over both of my legs. The vehicle continued in reverse along the driveway, struck a trash container and went up the incline at the main road. It crossed a busy two lane road and into my neighbors yard. The vehicle came to a stop about 10 feet from our neighbor's house without striking anything else. We purchased this car used with just under 300 mile on it. During the time that we've owned it, it has randomly flashed a "Shift to Park" warning lamp on the dash when I shift it to park and turn it off. It has never done what happened to me today. A few months ago, my husband and I took the car to the GM dealership to have it checked out before the warranty expired. We told them about the "Shift to Park" warning lamp and that the car was shifting hard while driving it. They kept the car a few days and told us they were unable to find anything wrong with it.

The original issue was that the temperature gauge was pegged on cold and the A/C was inoperative. The vehicle’s fans would run continuously even when the engine was cold. This created a safety concern since the engine’s actual temperature could not be monitored, and loss of A/C affected drivability in hot conditions. The issue appears related to the engine’s coolant temperature sensor or thermostat system, which causes incorrect signals to the temperature gauge and HVAC system. The condition has been reported by multiple owners of the 2020 Chevy Blazer 3.6L. In my case, the malfunction happened suddenly and has been repeatable. There were no prior warning lamps until the issue occurred, at which point the temperature gauge stopped working properly and the air conditioning failed.

To Whom It May Concern, I am writing to formally file a complaint regarding ongoing and persistent issues with my 2020 Chevrolet Blazer. The vehicle has exhibited repeated problems that I believe may indicate a broader safety or mechanical defect, and I am requesting that the NHTSA investigate these concerns further. Since purchasing the vehicle, I have experienced the check engine light turning on and off repeatedly, without consistent resolution. The following issues have occurred over time, all seemingly related to the engine or control systems: Engine Cooling System Failure: The first major issue involved the engine cooling system. This caused the vehicle to overheat and required service. I was concerned about the potential for engine damage or fire risk due to excessive heat. Variable Valve Timing (VVT) System Malfunction: Shortly after the cooling system issue, the vehicle began experiencing problems with the variable valve timing system. This not only affected performance and fuel efficiency but also caused the check engine light to illuminate again. Steering Control Assist Sensor Warnings: Most recently, the steering control assist sensor has started to malfunction, with warnings frequently popping up on the dashboard. This has impacted steering feel and raises serious safety concerns. Despite multiple service appointments and repairs, these problems persist or reappear. This cycle of temporary fixes without a lasting resolution is both frustrating and concerning from a safety standpoint. I am requesting that the NHTSA look into whether these recurring engine and control system issues are part of a known defect or recall-worthy problem affecting the 2020 Chevy Blazer. Thank you for your attention to this matter.

Ongoing Engine and Steering Sensor Issues – 2020 Chevrolet Blazer I am filing a complaint regarding repeated safety and mechanical issues with my 2020 Chevrolet Blazer. The vehicle’s check engine light frequently turns on and off, and I have been informed by technicians that it is related to the thermostat system. This issue negatively affects the vehicle’s performance and reliability. Additionally, the “Steering Assist is Reduced – Drive with Care” warning continues to appear while driving, even when weather and road conditions are normal. This error is reportedly due to a steering control assist sensor, and it raises serious concerns about the safety and handling of the vehicle. The alert causes uncertainty and could potentially impact the power steering functionality, creating a hazardous driving situation. These issues have occurred multiple times despite maintenance, and they appear to be part of a broader pattern of defects affecting other owners of this model year. It is unacceptable for a vehicle this new to have persistent problems that affect both engine operation and steering safety. I urge the NHTSA to investigate these recurring issues with the 2020 Chevy Blazer’s thermostat system and steering assist sensor to determine whether a recall or manufacturer intervention is warranted. Safety should not be compromised due to what seems to be systemic defects. Thank you for your attention to this matter.

What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple components in the engine timing and transmission system have failed. These include: Camshaft actuator solenoid valve failed twice (at ~30,000 and ~60,000 miles), each time with different DTC codes. Camshaft positioning sensor failed, triggering P0024 (“timing advanced and bouncing around”). Timing chain tensioner spring failed, requiring re-timing. Camshaft carrier case gasket experienced a major oil leak at 59,000 miles. Thermostat failed. Battery was replaced, but no diagnostic testing was performed—only code clearing. At 82,000 miles: Torque converter has failed, transmission fluid is tarnished, and the radiator is leaking internally. Yes, the vehicle is available for inspection upon request and has been registered as non-operational. How was your safety or the safety of others put at risk? The vehicle exhibited repeated hesitation, delays when accelerating, and revving while braking. In stop-and-go traffic, it now sputters as if it may stall. These behaviors create unsafe driving conditions, especially at intersections and in congested areas, putting both myself and other drivers at risk. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The torque converter failure and transmission issues were confirmed by National Transmission in Long Beach, CA. Prior component failures were confirmed by Martin Chevrolet, who performed both camshaft actuator solenoid valve replacements under warranty. Multiple DTC codes were recorded and cleared, but no electrical testing was performed. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been serviced by authorized GM dealerships, but GM did not escalate the issue to their TAC (Technical Assistance Center) or assign a field engineer, in violation of GM's internal escalation policy. No inspections

Questions Answered Below: What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle is at a GM Dealership now and is available for inspection. I have not authorized repairs as of yet. I am being told by the dealership: The ball joint on the control arm on the left side seized snapping the axle shaft - causing the tire to to turn out. The dealership has suggested: Mechanical repair costs $1,850, Plus an additional $2,000 due to wheel well damage caused by the failure. Has the problem been reproduced or confirmed by a dealer or independent service center? I am being told by the dealership: The ball joint on the control arm on the left side seized snapping the axle shaft - causing the tire to to turn out. How was your safety or the safety of others put at risk? Due to my slow speed turning out of the parking lot ~10 mph - the vehicle came to a sudden halt. However, had this occurred while driving any faster - it would have been very dangerous and put myself and others at significant risk. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was towed by AAA and has been inspected by the GM Dealership. That is the only inspection thus far. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Earlier in the day while pulling out of a parking spot and turning the wheel to the left I thought I felt some type of resistance then it went away as I started driving. No other symptoms or warning prior to the failure.

Thermostat is faulty at 55k miles. Purchased 2020 Blazer RS, certified used from Chevy in October 2023. Less than 1 yr later, thermostat is stuck on cold, no ax or heat, drivers assist reduced notice. Same issues as previous documented complaints. The frustration is why this known issue is not covered under warranty or recall! I just had my 50k maintenance service done while this issue was occurring- service told me “well we cleared the codes” , 2 days later check engine is on, temp stuck on cold, fan is over worked and no a/c or heat- and driver assist turns off. The safety issues around causing more engine damage by improper cooling and reduction of driving assistance. Additionally, parking issue with vehicle not recognizing it’s in park and having to wiggle or jam the shifter- car drains battery and won’t lock until resolved. Car is took expensive to have a $1200 replacement not covered under warranty!

6/12/2024 In Damon Parking lot in Rochester MN. Going less than 10 miles an hr- cars in front of me and behind me looking for a parking spot. Stop and go at times. Went to turn corner to go from one level to the next and my BLAZER took off "like a bullet". No control over accelerated speed- hit outer cement wall and slammed into 2 parked empty SUVS. Could not go any farther. The 2 SUVs slammed into cement wall in front of them. Injuries to both my passenger and myself. I have no idea what happened - it was so fast- I do know I had no control over accelerated rate causing accident. My 2020 Chevy Blazer was totaled- It was inspected by American National Insurance CO. Absolutely no warnings. Police report did not include any witness. Blazer is in the hands of the Insurance Co.
