ELECTRICAL SYSTEM

4 complaints

Telecommunications module failed - no Onstar, no Navigation which means no help to find charging station, and Mychevrolet app remote connection is not functional. Local dealer states this is a known issue but there is a significant backlog to investigate, and no loaner vehicles available. Wide spread issue across many GM vehicles. Very disappointing experience including service repair. Due to lack of loaner i am unable to drop off as this is my primary driven vehicle.

Telematics control module failure

Dec 19, 2025

Published date: 09/6/2024 Preliminary Information PIT6231 Poor Sound Quality On A Phone Call GM Dealers are not recognizing this service bulletin to remedy the microphone issue. This is a life safety issue and a formal recall notice should be issued. Reason if the driver or passenger is injured in the vehicle the same microphone is used to communicate with the SOS and On start. when some one is incapacitated or suffered an injury they would not normally be able to speak in such a loud volume for the recipient to hear and when the person speaking who has been injured is forced to yell into the microphone (if able) the receiving end only will her distorted audio,. It is for the reasons set forth above I respectively ask that this be considered a recall and not addressed by a service bulletin

The infotainment system of a brand new 2025 Blazer EV is doing blackouts, flickers, and changing commands and requests. While this may sound trivial - and if this system just did the radio - I would agree. However it controls most all the sub-systems of the car from Charging, to Display, to GPS, Environmental, etc. While at home it is just annoying and frustrating - we traveled to VA from FL this past week. Traffic was horrendous due to a closure of I95 in SC - ALL traffic was forced onto 2 lane country roads. Attempting to use the Controls, adjust GPS for alternatives, and adjusting displays - the glitches were causing either unexpected actions - or distracting longer than expected and causing near accidents. In addition I report that the "collision avoidance" is marginal or dangerous. Dangerous with it engaging maximum braking for a Marker-Barrel that no where near my path - to not engaging well enough when vehicles were rapidly braking (and they did not have brake lights). Finally - the GPS system "changes" destinations on its own. Again with the display flashing and blacking out - it is difficult to notice these "changes" when travelling on back-roads with insanely heavy traffic.

VISIBILITY/WIPER

2 complaints

The visibity in sunlight is dangerously impaired with the reflection of the dashboard on the windshield . Hard to see and really distracting while driving .

I was driving on a rainy day, and noticed my windshield wipers were not working. I tried adjusting wiper speed and even the spray function, which sprayed but did not wipe. At this point I had driven over a mile and had to pull over because visibility through the windshield had gotten so bad. I restarted the car and the wipers functioned normally again. There were no warning lights of any kind or software notifications, and the wipers had worked previously that day.

SERVICE BRAKES

1 complaint

On December 22, 2025, I purchased a brand-new Chevrolet Blazer EV SS from a dealership located approximately 1 hour and 10 minutes away from my home. Immediately after leaving the dealership lot, I noticed a grinding / grunting noise coming from the vehicle. This was not a minor rattle or normal “new car” sound—this was an alarming mechanical noise in a vehicle that had just been sold to me as new. Because the selling dealer is so far away, and because I was concerned about driving a potentially unsafe vehicle long distance, I took it to a closer Chevrolet dealer for evaluation. I first brought the vehicle to Ciocca Chevrolet in West Chester, PA. After assessing the issue, they advised me to open a ticket with General Motors (GM) because they believed there was a legitimate defect that required GM involvement. Shortly after that, I left for the Christmas holidays, but the issue did not go away and I remained extremely concerned that I had just bought a defective vehicle. When I returned, I took the Blazer EV to Del Chevrolet in Paoli, PA for a second opinion and a thorough evaluation. After keeping the car and spending an entire day assessing it, Del Chevrolet acknowledged the problem. Despite two separate dealers identifying and acknowledging the issue, I have been unable to get timely action toward a repair. I have been told that GM is requiring additional testing and, most importantly, that GM is not authorizing Del Chevrolet to order the necessary parts. The dealership has indicated they are essentially stuck waiting for GM approval, which means my brand-new vehicle is in limbo with no clear repair timeline. As of now, the vehicle has only about 140 miles on it. This is a brand-new car that developed a serious noise immediately upon delivery, and I have now been forced into a loaner vehicle. It is Jan 17th. The vehicle is still at Del Chevrolet service center. Del Chevrolet, Fred Beans Chevrolet and GM corporate are involved in resolving this issue.
