2024 CHEVROLET BLAZER Complaints

Windshield has terrible glare and reflects the dashboard as to limit visibility. Front collision and auto braking including rear collision and braking are a safety hazard as they create hard braking events for no reason. Car will stop sudden for no reason. These are both serious safety issues. These are problems we have had with the car since purchase and have had the dealership shop work on the problem and were told just to leave it turned off. This is not the correct way to fix a problem with a vehicle.

On April 7, 2025 while backing out of the driveway, my son's car abruptly stopped. The manhole cover at the end of our driveway triggered the emergency braking system. My head was slammed against the headrest and caused a great deal of pain in my head. On April 15, 2025, I went to Kaiser and was told that I have a concussion.

While driving the vehicle the reflection from the dashboard onto the windshield on a sunny day causes vision to be impaired to where sometimes you cannot see pedestrians or animals at certain angles. This happens constantly while day driving and increases in impaired vision depending on the direction of travel relative to the sun.

I am writing to report a serious safety concern regarding the adaptive cruise control and rear cross-traffic alert systems in my Chevrolet Blazer. These systems are malfunctioning in unpredictable and potentially dangerous ways. On multiple occasions while driving on the expressway, the adaptive cruise control has abruptly and forcefully applied the brakes without any apparent reason. There have been no vehicles directly in front of me posing an immediate threat. While there may be traffic in adjacent lanes, my lane has been clear. This sudden deceleration is alarming and dangerous, creating a significant risk of rear-end collisions from vehicles following too closely. The red lights will come on and indicate an imminent problem but it is a malfunction. The abrupt stops are frightening for all passengers, and the frequency of this occurrence is troubling though on rare occasions since I have first owned the car. I have observed similar complaints from other Blazer owners on online forums, reinforcing my concern that this is not an isolated incident. The dealer has not being able to reproduce but acknowledges that other drivers have a similar issue. Further compounding this issue is the malfunctioning rear cross-traffic alert system. While backing up at low speeds, the system will unexpectedly and forcefully engage the brakes, even when there are no vehicles present in the surrounding area. While less dangerous than the expressway issue, this erratic behavior still indicates a significant system flaw. I understand that adaptive cruise control and rear cross-traffic alert are intended as safety features, but their current malfunctioning poses a substantial safety risk. I urge you to investigate this matter thoroughly. I expect these features to function correctly and reliably. I request immediate action to address these defects and ensure the safety of myself and other drivers.

When making left hand turn the AEB activated for no obvious reason almost causing rear end collision chain reaction for traffic behind making same left hand turn.

The signal continues to bounce back too hard after many right turns and light up my left signal about three times. Additionally, it's sometimes difficult to engage the right turn signal at all.

Right rear tail light failure. Does not light up with headlamps on or when braking and flashes very fast when signal is turned on. Get a warning message on the info screen stating "Right Rear lamp failure" every time I signal a right turn. Dealer documented issue but states that this is a known issue with no fix at this time and GM instructed dealer to not attempt any repairs at this time. This is a known issue in the GM forums about this vehicle and it is always the right rear LED lamp that has this problem. Potential safety issue when no brake light lights on that side of the car and the fast flashing directional may be confusing to traffic.

On one occasion, the doors locks failed to respond to multiple unlock attempts (using the buttons on 3 of the handles and using the remote). After 5 minutes or so, the door locks finally responded to a command from the key fob to unlock.

On several occasions (10+) the windshield wiper would not activate when turning the dial on the stalk. On all but one occasion, the stalk worked on the next drive. That one occasion, the stalk worked on the following drive. There are no lights or warnings, the wipers just fail to work. This is more problematic

I’ve been in pain for 3 days since the last time my auto braking slammed on the brakes. The situation this time was in the school pick up line, where there are 3 rows of cars and I was in the middle lane. This is a very slow progressing line bc each lane has one car move forward at a time and we then move forward and stop It slammed on the brakes so much harder than I would even have been braking in that scenario and I thought I’d been rear ended. It’s happened another time when I was in moving traffic and created a very dangerous situation which fortunately we did not end up causing a crash. I’ll be disabling the feature immediately as it’s much more dangerous than useful and I am in so much whiplash pain this time around it’s insane
