VISIBILITY/WIPER
When driving during the day, specifically facing the sun, there is a glare on the windshield from the dashboard which decreases visibility. it makes it very difficult to see anything to the right of center for the driver and almost impossible for the passenger to see anything directly in front of the vehicle at times.

ELECTRICAL SYSTEM
The right side tail signal light module needs to be replaced. I was having intermittent issues with the right turn signal, I took the car to the dealership and they told me that the module needed to be replaced. The car has been in the dealership since March 19th, more than a month ago waiting for the part. I contacted Chevrolet and they keep telling me that no ETA for part is available, and they do not provide any more details on what is causing this delay.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

VISIBILITY/WIPER, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

VISIBILITY/WIPER
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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
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.

EXTERIOR LIGHTING
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.

EXTERIOR LIGHTING
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.

VISIBILITY/WIPER
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

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
The vehicle will automatically extremely hard brake while moving for no apparent reason, with no obstructions present. This problem startles driver and passenger and can present a danger to vehicle of being hit by other vehicles not expecting a hard braking situation for no apparent reason. Please investigate and make manufacturer responsible to fix the issue. Thank You

SERVICE BRAKES, BACK OVER PREVENTION: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When the Automatic Emergency Braking system is enabled, it will suddenly brake when in reverse even though there is no obstacle at the back. The braking is so sudden that it is painful. I reported it to the dealership but they never got back to me about a solution. I have disabled the AEB for now.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM
The contact's daughter rented a 2024 Chevrolet Blazer. The contact stated that while his daughter was driving at an undisclosed speed, after driving over a small imperfection in the roadway, there was an abnormal scraping sound coming from underneath the vehicle. The driver pulled over to the shoulder of the roadway. After a visual inspection, the contact observed that the exhaust mounting bracket had disconnected. The vehicle was taken to an independent mechanic by the rental company, and the vehicle was repaired; however, the contact’s daughter was not provided with the diagnostic results. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 29,000.

SUSPENSION
Rear suspension was always a little noisy, but ~1,850 miles the driver's side rear sounded like it was detached and breaking through the strut tower. I quit driving the car and make an appointment to drop it off at the dealership on 12/5/24. Dealership confirmed that "fasteners" were broken on the rear strut, in a place that cannot be easily accessed, and confirmed multiple times that it is definitely a problem that existed from the factory. There are two pins on the rear struts that are broken off on my vehicle, and the dealer _strongly_ advised against driving it. My car has now been at the dealership for 51 days as they are awaiting inspection by GM as well as instructions and approval to fix, and the dealership noted that they need to figure out how many cars this affects as well as what the fix will be.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
This vehicle with a total of 700 miles on the odometer, gave several warning notifications this morning on my way to work. Service high voltage system, reduced acceleration notification. I was on the interstate and suddenly became unable to accelerate to keep up with traffic, creating a dangerous situation for my safety. This is a know problem with the Blazer EV, as GM had previously issued a stop sale order in December of 2023, a supposed software update was issued and they continue to sell the dangerous vehicles, as the software update did not fix the problem as I just experienced it today, on a car I bought brand new 2 weeks ago with 700 miles on the odometer.
