2023 JEEP Grand Wagoneer Problems & Complaints

At engine idle with vehicle parked or driving in heavy traffic, exhaust fumes are entering the passenger compartment. I am not aware of any apparent exhaust leak. The fumes seem to be entering by way of the fresh air intake. I have confirmed CO readings with 2 different detection devices. If the vehicle is moving the readings have been 3-96 ppm. If the vehicle remains stopped with engine running, readings have been +100 ppm. This is a life safety concern. My local dealer had a service appointment over 1 week out 10/22/25. I asked Stellantis to escalate the case and have a reference number. # 94485584 I have lost the use of my vehicle and have not received a closer service appointment.

Vehicle over heated disabling vehicle on freeway. This was a know problem with this manufacturer.

2023 Grand wagonner : Vehicle overheats while driving and completely stops in the middle of the road with no time to pull over safely. This is the second time it has happened in a year of owning it. Check engine light has been on since the first time it overheated and dealers say they don't know why.

On Sunday, February 2nd we were driving down the highway when the front sunroof on my Wagoneer spontaneously exploded. Thankfully I had the shade closed, so it caught the broken glass. Had it been open, who knows what would've happened. There were no other cars around, no overpass...just us on the highway. The dealer has the vehicle now, but it doesn't sound like it will be covered under our warranty. However, when I google "my wagoneer sunroof exploded," there are tons of results of people having the same experience.

My camera system does not send the camera views from any of the 4 camera locations to my radio screen. Rear camera including when I put in reverse, front view and 360 degree view all do not report to the radio screen, it is black with the parking assist lines.

The outer edge of the front tires is wearing prematurely. There is also a vibration felt in the vehicle at highway speeds.

The driver side sunvisor comes loose and dangles causing an unsafe driving condition. Dealership has repaired multiple times but it continues to happen. It is an inherent design flaw that is going to cause accidents and ultimately loss of life.

similar to TSB 23-015-22, our Grand Wagoneer/Wagoneer has a windshield with vertical distortion in the center area of the windshield surface. This distortion is in the glass and impacts our ability to see clearly and also makes passengers car sick.

Side steps will deploy then immediately go back up causing it to trip up a passenger. The doors will lock and not unlock, even with the key fob in hand.

To the National Highway Traffic Safety Administration (NHTSA):Subject: Safety Issue Report: UConnect System Malfunction in Jeep VehicleDear NHTSA,I am writing to report a significant safety concern with the UConnect system in my Jeep, which has been malfunctioning for the past four months. The system's failure to recognize voice commands and manage remote commands compromises the vehicle's safety features, including hands-free calling and potentially emergency assistance services. This issue is covered under warranty, yet despite repeated attempts to have it addressed by Jeep, there has been no resolution.The malfunctioning UConnect system, crucial for safe vehicle operation by minimizing driver distraction, is not responding correctly, indicating a possible hardware or software failure. Given the importance of such systems for vehicle safety and the refusal of the manufacturer to correct the problem under warranty, I am seeking your intervention to ensure the issue is adequately addressed.I believe this could represent a broader safety issue that may affect other drivers and request that the NHTSA investigate the matter further to ensure vehicle safety is not compromised.Sincerely, XXXXX Attached is my husband's email communication chain. Other complaint information will be available from the Jeep internal system. We are not sure if this is an electrical problem. But we reported issues that seemed unrelated up until now whereas a strange smell and electrical malfunctions existed from the moment we purchased the vehicle brand new. It is odd that only select services requiring telecommunications don't work, but they do seem to work to contact Jeep. We mentioned this smell as exhaust or burning smells in the vehicle but were told this is normal essentially and have still not gotten a response from a Technical Team that either doesn't exist or is nor actively addressing the issue. It seems to be electronics involved and UConnect may be tertiary to the issue.

This has happened twice to me already. first time in 10/23 and again 3/2024. power steering failed without notice while driving making it very hard to control the vehicle. Had to have it towed both times to the dealership for repairs.

Went to start the vehicle, and there was no power steering at all. Several warnings on the dash to have it serviced. Had a tow truck come take it to the nearest Chrysler Dealership for service. Waiting for diagnosis

An overheating engine causes the truck to shut down completely, block the power steering engine, and become undrivable. Electrical and harness assembly problems The dealership inspected the truck and attempted to repair it, but the same issues have recurred and are nearly causing an accident while driving on a highway.

Assessment of Ongoing Mechanical & Safety Issues – 2023 Jeep Grand Wagoneer To Whom It May Concern, I am providing a clear, factual assessment of the ongoing issues with my 2023 Jeep Grand Wagoneer, which I purchased for $108,000 and have owned for less than two years. During this time, I have experienced twelve separate mechanical and functional failures, several of which have rendered the vehicle undriveable for prolonged periods. Below is a summary of the major issues that continue to impact the reliability, safety, and usability of this vehicle. 1. Seat / Massage Mechanism Defect (Ongoing for Months) A malfunction in the seat massage system has created a large, hard protrusion in the driver’s seat. This defect has resulted in significant back pain, requiring both urgent care and follow-up medical evaluation. I have now been diagnosed with sciatica, which my physician has indicated is likely related to prolonged pressure and improper spinal support caused by the seat malfunction. Two dealerships have confirmed the issue and ordered the replacement part months ago, yet the part delivery has been repeatedly delayed, most recently to January 6, 2026. This has affected my ability to safely and comfortably operate the vehicle, and has now escalated into a documented medical issue. 2. Suspension Noise During Auto-Leveling The vehicle’s air suspension system produces extremely loud noises during auto-adjustments. This raises concerns regarding the safety and structural integrity of the suspension system. 3. Window Hinge Failure A window hinge has prematurely failed, requiring service intervention. This is not consistent with typical wear for a vehicle less than two years old. 4. Cruise Control Malfunction The cruise control system intermittently ceases functioning while driving. The only way to restore it is to turn the vehicle off and restart it, which presents a safety concern when traveling at highway speeds. This points to a possible electrical or

Vehicle shuts off and puts itself in park at intersections while pulling across traffic. Multiple warning lights. 4x4 faults, power steering faults, auto start/stop faults etc. happened once just after I let off the brakes to start moving and lost power brakes

On October 20, 2025, at approximately 2:00 PM, while driving on the highway to pick up my children from school, the driver-side back cushion (airbag/cushion system) in my seat unexpectedly deployed or inflated with significant force, striking my back. The impact was strong enough to leave a visible mark, which I have documented with photographs. As a result, I experienced immediate back pain and was at serious risk of losing control of the vehicle due to the sudden and forceful nature of the incident. I immediately contacted my doctor’s office following the incident. My physician confirmed that the injury was consistent with trauma caused by the seat mechanism. I then contacted the dealership where I purchased the vehicle. I was instructed to drop off the vehicle and leave the keys in an envelope. On the morning of October 21, 2025, I received a text message from the dealership indicating an initial estimate of $117.65. I called the dealership to request a written report of their findings and to inquire whether there were any recalls or service bulletins related to this issue. I was informed that no recalls or service bulletins existed and that I would be required to pay for further evaluation. The dealership declined to take responsibility for the issue and also stated they could not provide a written report. As of this date, the vehicle remains at the dealership with no resolution, updates, or further communication provided. This is a serious safety concern that requires immediate attention and proper documentation.

AEB system engaged emergency braking for no apparent reason when traveling at >35mph on a busy road with the flow of traffic. My face actually hit the steering wheel and a car traveling behind me barely stopped in time to avoid rear ending me. The AEB system has repeatedly displayed warning lights in the dash previously. For each occurrence, the vehicle was serviced at the dealership and reassurances were provided each time that the underlying issue was remedied with reprogramming and/or replacement of electrical control modules, however the recurrent nature of the issue (and many other issues surrounding the electrical system in my Grand Wagoneer) doesn't instill confidence in the "fix" they're providing. At this point in time, I don't feel safe driving my Grand Wagoneer, as I don't know when the vehicle will involuntarily slam on the brakes in traffic and cause an accident.

My brakes stoped working yesterday. The petal went to the floor and there were NO brakes. I was able to put the car in park and stop its movement. The vehicle is at the dealership. This is what they told me- BCSM AND ELECTRONIC BRAKE BOOSTER FAILURE. C0021

The contact owns a 2023 Jeep Grand Wagoneer. The contact stated that while his wife was driving approximately 65 MPH on the highway, the vehicle lost motive power and shut off. The vehicle was later towed to the local dealer, who diagnosed that the thermostat had failed, causing the engine to overheat. The contact was informed that the valve inside the thermostat had bound, causing improper internal operation of the thermostat. The thermostat was replaced, and the vehicle was repaired. The contact was informed that per TSB: 09-006-25, the same style thermostat was installed to repair the vehicle. The manufacturer was notified of the failure. The failure mileage was 17,500.

While driving my 2023 Grand Wagoneer the Serv 4WD light and dash spelled out Service four wheel drive, it lit up the anti collision light, ECS, TCS, and HOLD!. The parking brake also engaged automatically while driving at least 4 times. This is a serious safety concern to allow a vehicle to continue driving with the ability to automatically engage the parking brake while driving. The safety of my entire family was put at risk. I currently have the vehicle sitting at the dealership to be diagnosed and reproduced as the vehicle lost all power after this incident. Another serious safety concern is the total loss of power with no notice. This could easily have been while I was driving and caused a serious accident and possible fatalities.

See attached document for complaint.

The contact owns a 2023 Jeep Grand Wagoneer. The contact stated that while driving at an undisclosed speed, the vehicle stalled, and the engine overheated with the check engine warning light illuminated. The vehicle was restarted; however, the failure recurred. The vehicle was taken to the dealer where it was diagnosed that the fuel sensor had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power with the check engine warning light illuminated. The vehicle was restarted. The vehicle was taken to the dealer where it was diagnosed that the fuel sensor failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 33,363.

While driving 25mph, the brakes went out. 2 warning lights came up " service electronic stability control" followed by "service anti-lock brake system" We were able to pull into another lane and still to a stop but vehicle was not responding to brake being floored.

We the dealership technician had the vehicle for a repair, he was driving it back-and-forth to work like he owned the car and one day He was leaving his home to go to work and the suspension failed so that had to be fixed and that was back on one of the many time it was in the shop. The stop/start engine doesn’t engage for me when I break for me. For me to get it to engage I have to slam on the break as if I was bracing for an accident and then the stop/star engine mode will engage. I think this vehicle has had five clusters replaced in the car, due to the parking sensors, side warning sensors not working. I believe the fifth one went in Dec 2024 once again. The vehicle was in the shop from November 22, 2024 until yesterday DecemberI 2, 2024 when I picked it up. I got home and the parking sensors didn’t beep off and I could’ve crashed it into my garage door and I went through the system and it was already selected to beep but didn’t, then I started getting a message saying that the side warning sensors are unavailable. I put it in reverse it tells me the wipers are off, so maybe all the clusters that they’re making are faulty. The Jeep Retention Customer Service even sent a specialist, technician assistant to the dealership twice or three times to deal with this issue and it’s still not fixed. The dealership Service Center has put in request for answers of how to fix these problems and have had to wait weeks for answers because they don’t know the answers of how to fix the problems with these vehicles and they send a specialist and still the problems still occur they say put in a new cluster a new cluster gets put in the problem still happens. The part is shipped directly from a manufacturer and they have no ETA on that part and my car would still be in the shop, but the Jeep Retention Customer Service Rep had it expedited but the problem is still ongoing. THERE NEEDS TO BE A RECALL ON THIS CAR AND PEOPLE SHOULD GET THEIR MONEY BACK

Engine shut down on highway while doing 55 mph. Almost was in a crash with multilabel cars. Second issue Forward Collision Warning failed on a sunny morning. A semi rolled and dumped it load causing the cars in front of me to stop suddenly. The Forward collision did nothing and did not apply my brakes. I missed the car in front of mine by a couple feet.

Received over the air update that continues to fail. This over the air update shut down my driver information screen and altered the driving measures and safety features. This vehicle continues to receive over the air updates that freezes my driver information and infotainment screens. This results in me having to stop an disconnect the battery to reset/ restore safe driving information. Vehicle receives phantom vehicle warning and error indications.

We took the car home on 5/4/24 & while drive it home we started to get a binging noise, I got scared I thought the car was braking down & a message came on the instrument panel Driver 1 info & then it went away & then a few minutes later more binging this message was check 2nd row seat belt latch, stop driving also the screen,radio,and air conditioner, shut off then it come back on after a while.We had a lot going on & we had to wait for a passenger side mirror to come in because of prior damage being done to it & scratch marks that need to be buffed & everything could be done at one time.Still driving the car and picked up my parents at the airport 5/15/24 and same electrical issue coming across the instrument panel.On 5/22/24 took my parents to the airport and they were in the 2nd row seats & the 2nd row latch message came up three different time while I was driving @ 70 mph and couldn't do anything didn't have a screen,radio,air conditioner or anything.On 6/4/24 the engine light came on while driving & stayed on.Took it in on 6/5/24 & they couldn't duplicate any of the problems and they must of just reset the engine light because we pick up the car on 6/6/24 & when I driving home both the 2nd row seat belt issue come on, & Driver 1 Info I was doing 41mph when it shows up on the instrument panel & the check engine light came on the next day 6/7/24 we took it to another Dealership & they were able to duplicate all the problems. From all the service records that I can see there has been electrical system problems sense10/2/23, 2/19/24, 2/26/24 also wiring repaired done & all these issues where reported by two different Dealership before being purchased by us and the problems still keep happening 5/4/24,5/6/24,5/7/24,5/8/24,5/9/24,5/10/24,5/15/24,5/18/24,5/22/24, 6/4/24,6/5/24,6/6/24, & the seat belt problem sense 2/15/24 & continue until this day. This another Dealership has duplicate all of the problems, but they have no solution for these issues.

I have a 2024 jeep grand wagoneer. It has been activating it's emergency braking system randomly while driving. One time it was on a road with a 55mph speed limit the car beeped and slammed on the brakes. Morning sunny no traffic car was clean and free of dirt. Second time was on a 2 lane road speed limit 35 day light car beeped and slamed on the brakes the behind me had to go into oncoming lane to avoid hitting me. The 3rd time was after leaving the dealership after the 4th time in for service for them trying to figure out why the truck is doing this. Was on the cross street from the 2nd time. This time it high lighted a mail box in the night-vision mode and slammed on the brakes again day light no traffic car was clean. Mail box wasn't hanging in the road. We opened a case with FCA for a buy back they denied it. FCA also has not issued a stop drive order. We are currently using my wife's car to transport the kids as we do not feel comfortable with the issue not being resolved with FCA. My wife has the same truck hers is having the same issue but not slamming on the brakes hers is in currently with jeep engineering and they want us to record the car when it actives the system with our phones while driving. We feel very unsafe driving the cars and is hoping NHTSA can step in with some help. At the end of the day we are both trading our less than 1 yr old trucks in for another brand and is losing around 30,000 between the 2 vehicles.

New vehicle with under 4,000 miles was being driven on a busy parkway when the engine suddenly stalled and would not restart. No visible warning lights prior to stall. Incident occurred just past the top of a hill, creating the potential for a rear-end collision. A police officer was called and arrived, parking behind the stalled vehicle with emergency lights flashing in order to prevent a collision. The driver of the vehicle tried repeatedly, 5 or 6 times to use the vehicle's built-in roadside assistance to get help but got disconnected every time before a tow truck could be dispatched. Vehicle was in the middle of the highway for over 20 minutes. Dealer confirmed engine has seized and has to be replaced.

This is a new 2023 Grand Jeep Wagoneer Series III L with an inline six HO engine that seats eight passengers. After about 500 miles or less, we noticed the vehicle shaking at highway speeds. Since it has only worsened, it has been to the dealership four times for a fix, without a solution. They exchanged the Pirelli tires for a Michelin, which did not fix this vibration error. While at highway speeds, everything shakes; the front headrest visibility shakes a lot, and the water in water bottles in the center console has a funnel effect, which clearly shows it’s a vibration issue, not a bumpy road issue, also, while seated, the floorboard and the seats, motorist, and passenger you can noticeably feel the vehicle shaking; at one point, my wife started to feel sick. As a result, now she only rides in the back seat. This ultra-luxury vehicle has an intense vibration issue while at highway speeds; the roads are smooth, and we tested it across three states while doing a family trip; it's clearly something with the engine mounts, suspension, or a drive shaft that is not well balanced. The dealership told us that they could not do anything because they did not know how to fix it as they drove other vehicles, and some shook too, even worse at around 40mph. They stated this is normal for the vehicle. Well, it’s not normal for a vehicle, but it might be for this model because of poor engineering or QA parts issues. Either way, my vehicle is not safe to drive; with this vibration only getting worse, I fear it will cause a serious accident or damage the vehicle, shortening its life span, and at 120k, this should not be the case. We want what we paid for and want this issue fixed ASAP.

A power failure inside the vehicle causing it to crash at a gas station it's been in a shop for almost 3 months now while we are paying almost 2k a month for the loan, we asked Jeep to cancel the contract and give us our money back they refuse since we had so many problems since we brought that brand new vehicle. We need help from your organization now.

The contact owns a 2023 Jeep Grand Wagoneer. The contact stated that the stop and go and lane change features were not working. While reversing, there was no audible alert. The auto-air lift system failed to engage. Upon accelerating, the vehicle was making an abnormal sound. The navigation screen was flickering. The contact noticed open wires under the driver's side front seat. There were no warning lights illuminated. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and offered to buy back the vehicle. The failure mileage was approximately 800.

We brought this Brand-new Wagoneer on April 19th, 2023, since then we've been having a lot of issues with the vehicle, On August 7th, the electrical system failed we took it to the dealer, and they upgraded for us. Again, 3 weeks later while I was driving home from Sam's club, the power steering light keeps flashing, I had trouble with the wheels i pulled to the side turned off the car for 5 minutes then light went off and I was able to drive again. Few days ago, on October 16th the vehicle electrical system shut off again, none of the buttons inside the vehicle works, the screen went off completely. I was too busy at work that day and did not have time to drop off the vehicle. On Wednesday October 18th after I pick up my daughter from school, the vehicle completely shut off at a Gas station, I decided that vehicle was not safe to drive and decided to drop it to the dealer, as I was leaving the Gas Station nothing works inside the car and we hit a pole at the gas station which severely damaged the front Bumper. We reached out to Jeep and was told to drop the car to the nearest Jeep dealer, and they will fix it. When we got there, they fixed only the electrical problems inside the car but refuse to fix the bumper which was cause by the forward collision avoidance system failure to engage due to the electrical problems. We pick up the car Saturday morning now the automatic break light is on, and the battery keep discharging. We want your firm to please help us as it not safe to drive that vehicle now. We are very afraid and wants jeep to either replace the vehicle with another one or fully refund the purchase price.
