2025 Chevrolet Blazer owner complaints

the onstar is out, cant make a call to them, cant remote start on app, navigation doesnt work

I am concerned about a significant safety issue with my 2025 Chevrolet Blazer EV. On at least four separate occasions, the vehicle has unexpectedly applied extremely hard Rear Automatic Braking while I was backing up, despite there being no object, vehicle, person, or obstacle behind the vehicle. The braking is so abrupt and forceful that it feels as though the vehicle has collided with something. Because the driver is typically looking over their shoulder while reversing, the sudden stop causes a violent jolt. This has resulted in neck pain and headaches for me and my son on multiple occasions. One of these incidents also occurred while my son was driving the vehicle. We discussed the event afterward and both experienced the same sudden, aggressive braking with nothing present behind th

The contact owns a 2025 Chevrolet Blazer. The contact stated that a GM inspector had inspected the vehicle due to phantom braking. The contact stated that while her husband was driving approximately 35 MPH, with her daughter in the front passenger’s seat and the contact seated in the rear seat, the brakes independently engaged, and the vehicle came to an abrupt stop. The failure had occurred three times. The contact had undergone cervical spine surgery six months before the failure, and the failure caused the injury to return. The contact's husband reviewed the Owner's Manual and discovered that the vehicle was equipped with the Automatic Emergency Braking (AEB) system and associated the failure with the AEB feature. The manufacturer was notified of the issue, and a GM inspector inspected

3 Times, while travelling at highway speeds, infotainment module and driver display went dark for at least 3 minutes. While in this state, there were no visual controls such as speed, turn signals, etc. - the entire dashboard was dark. Recurring codes are: U11FD(00) Raw code: D1FD00 ECU: 40[Archive (inactive)] Status: Confirmed, Test failed since last DTC clear

The contact owns a 2025 Chevrolet Blazer. The contact stated that the Forward Collision Avoidance system had erroneously activated on several occasions. While driving very slowly, the braking system suddenly activated while leaving a dealer. Additionally, while driving approximately 30 MPH, the braking system erroneously activated, causing the vehicle to abruptly stop. The automatic braking system was turned off, and the vehicle was later driven to the local dealer. The local dealer was unable to determine the cause of the failure and advised to deactivate the Collision Avoidance System. The contact sustained a neck injury during the failure while seated in the driver’s side rear seat. Medical attention was required. The failure mileage was 7,000.

I was going to park in a parking lot, when my car suddenly accelerated rapidly crashing into the building.

windshield leaking water inside of drivers compartment, headliner & side pillars (causing stained areas) as well as the top of onstar and electrical buttons on the overhead console . Found wet cup holder. Vehicle does not have a sun roof. GM is aware of this issue from the factory GM plant in Ramos Arizpe, Mexico. This defect is because of lack of not being sealed properly during the assembly process. The windshield has a factory OEM rubber seal attached to a NEW windshield. This rubber seal is NOT a part that can be purchased separately to fix the problem. By replacing the entire windshield with the new factory rubber seal and the channel that the entire windshield fits into is resealed with urethane should fix the issue.. Trying to reuse the current windshield & rubber seal and using sea

Just purchased a used 2025 RS EV on 5/2/2026. When I got home I found out the Google maps and on star app wasn't working. Called on star and they can't connect to the car and that the telematics module is probably bad. Checked my Chevrolet app and it reports that it hasn't connected to the car for over 6 months. Now waiting for replacement part going 3 weeks now. A little pissed off that dealer did find before they sold me the car.

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 bulleti

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 dangerou

What component or system failed or malfunctioned, and is it available for inspection upon request? On September 12, 2026, while parked at the top level of a parking garage, the vehicle unexpectedly began rolling forward after being parked and exited. The vehicle subsequently struck a concrete wall. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? On September 12, 2026, my son parked the vehicle on the top level of a parking garage. He exited the vehicle while I remained seated in the rear seat and his girlfriend remained in the front passenger seat. I later moved to the driver's seat to speak with her. As I exited the vehicle to meet my son, the vehicle unexpectedly started rolling forward on its own. Nothing was touched or int

Complete and total failure of the telematics module resulting in loss of self driving, onstar, WiFi, gps, and all connected services. Severe battery drain due to module forcing the vehicle to completely shut down while driving, resulting in loss of power steering and brakes.

The Telematics Module failed and is on backorder. This is a known issue across the U.S. This makes it so OnStar doesn't work and I am paying for it. Not just that the safety concern of it not working. GPS, Maps, Level 3 Tesla doesn't work. Car is really not usable as we can't charge on a level 3 when going over 100 miles. We have loss access to navigation, Google Built-In services, the myChevrolet apps, and even core safety and convenience features tied to connectivity, including OnStar and Super Cruise.

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.

Driving home about 25 mph, front passenger tire blew. Put donut spare on,. Took to Dealer next morning. front control arm bushing torn out of control. This is dangerous and should not have happened.
