Driver Assist & Collision Avoidance complaints by model year
I was on the interstate. Initially I heard a faint rattling sound. I turned off the radio and AC to listen more closely; the sound was not audible. But then traffic came to a standstill. As I slowed, that barely audible noise began to sound like something boiling in the engine. The temperature and pressure gages were all in normal operating ranges. I pulled to the shoulder of the interstate and checked under the hood. I noticed a distinctive squeaking sound although the fan belt was intacted in running true. There was no sign of any fluid loss in the engine compartment or underneath the vehicle. While attempting to get to a Chevrolet Dealership one exit away, the vehicle stopped running while at a stop light. additionally, there is a recall on this vehicle for the automatic braking system. GM and the dealerships are aware of this recall yet this website states there are no recalls.
NHTSA complaint #11750159 — an unverified report by a vehicle owner.
Driving in bumper to bumper traffic in my 2025 Tahoe and the automatic braking system slammed on the brakes at 10 mph causing me to get rear ended.The light turned green and traffic started moving forward and I'm hitting the gas pedal when my truck just slams on the brakes causing the girl behind to rear end me. The car in front of me was moving forward and never hit their brakes but my car still slammed on the brakes for no reason. I was probably 6 or 7 feet away from the car in front. This isn't the first time this car has slammed on the brakes for no reason. It always seems to happen in the summer during sunny mornings as I'm headed east driving towards the sun. I got lucky the other 6 or 7 times this has happened up until today

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The issue is related to Super Cruise hands free driving. During a recent long trip multiple times the Super Cruise signaled for lane change and tried to move into the passing lane with a car directly beside me. I have 8,500 miles on this car and have used Super Cruise extensively on highway driving only and until this last trip never had any issue with the system seeing cars in lanes beside me before. I only avoided a collision because I prevented the lane change by grabbing the steering wheel. This software bug will end up with injury or death of individuals unless Chevy fixes this immediately. Your help in investigating this is appreciated. I will add my son has a 2025 Suburban and has experienced the car trying to pull into traffic beside him.

The car has cut off three time while at stoplights. I can get it restarted but the dealership cannot duplicate it even though there are codes in the system. Also the automatic braking will randomly stop when it shouldn’t and it is a hard braking.
NHTSA complaint #11734328 — an unverified report by a vehicle owner.
I am filing a safety complaint regarding my 2025 Chevrolet Tahoe Premier for repeated brake assist/braking failures. Most recent incident: While driving, the check engine light came on. I turned the vehicle off for approximately 10 minutes and restarted it, but the check engine light remained on. Approximately 20 minutes later, multiple warnings appeared on the dash including: “Brake Assist Failure Press Hard to Brake,” “Speed Limited,” and “Service ESC.” At that point, braking ability was severely reduced. I was close to my destination and approached a stop sign. I intended to roll through the stop sign because the brakes were not functioning normally, but another vehicle suddenly approached. I pressed the brake pedal with both feet. The brakes were stiff and hard to press. The vehicle still did not stop properly and came to a stop in the middle of the road past the stop sign. After arriving at my destination, the vehicle sat for approximately 1–2 hours. When restarted, the brakes appeared normal again, but the check engine light remained on. In the MyChevrolet diagnostics app, it then showed warnings for Engine and Transmission System, Transmission System, and Four Wheel Drive System. While driving to the dealership afterward, the vehicle also began shaking. This same issue previously occurred on April 16, 2026. I was driving on the interstate when the brakes lost assist and the dash displayed “Service ESC,” “Brake Assist Failure Press Hard to Brake,” and “Speed Limited.” After reaching my destination, I was told by someone at the dealership to turn the vehicle off for 10 minutes to see if that would fix things, so I turned the vehicle off for about 10 minutes. When restarted, all warning lights were gone and braking returned to normal. I still drove the vehicle to the dealership that same day for service. This is a repeated, intermittent brake failure / brake assist failure creating a serious safety hazard and near collision risk.
NHTSA complaint #11733952 — an unverified report by a vehicle owner.
The component at issue is the engine, which suffered a sudden and catastrophic failure due to unknown causes. At no time prior to this incident were there any warnings, symptoms, or indications of an underlying mechanical defect that would have allowed for preventative action. While operating the vehicle on the highway with my family present, multiple warning indicators activated simultaneously, including a blinking check engine light, traction control light, ESC warning, and a forward collision warning. Immediately thereafter, the vehicle experienced a rapid and significant loss of power accompanied by a loud and persistent engine knocking noise, rendering the vehicle unsafe to operate and placing the occupants at risk. It is important to emphasize that traction control and ESC systems are not causally related to an engine misfire condition, further supporting that this event was abrupt and not part of a progressive or diagnosable issue. A diagnostic scan performed at that time identified a misfire in cylinder 1. Upon delivery of the vehicle to the dealership for inspection, it was determined that the engine had suffered complete internal failure and was deemed “blown.” This finding confirms the occurrence of a catastrophic mechanical breakdown. Based on the sudden onset, absence of prior warning, and severity of the failure, there is no reasonable basis to attribute this condition to normal wear and tear, operator misuse, or neglect. Rather, the facts support the conclusion that this was the result of a latent defect or internal mechanical failure beyond the operator’s control. Accordingly, this matter should be addressed under applicable warranty coverage or consumer protection standards.

On March 21, 2026, I rented a Chevrolet Tahoe (approx. 24,450 mileage driven). While operating the vehicle on a freeway at approximately 40–50 mph, the braking system and ABS failed suddenly without any warning. Barely no brakes were able to apply to stop the vehicle. It also started to show that ECS service (Electronic Stability Control) and Service Brake Pad Monitor. Many faults started to show.
NHTSA complaint #11726810 — an unverified report by a vehicle owner.
I have a 2025 Chevy Tahoe and the automatic braking system is way too sensitive. When I’m reversing, it constantly slams on the brakes even when I still have enough space and nothing is in my way. It also brakes when people are nearby but not actually in my path. One time I was stopped and about to move forward, and the car suddenly braked because a construction worker was a few feet away, not in front of me. It caught me off guard and didn’t feel safe. The braking is very sudden and aggressive, and it makes normal driving and parking difficult. It feels unreliable and could cause a dangerous situation.

My truck was driving perfect and I went to pull into a parking lot in Arkansas where I live in long story short it started acting funny trying to idle out and then I heard a knocking noise. It happened twice. Then my service ESV light come on next my motor light come on then my auto for a collision system failure light come on. It’s on the dash anyway my vehicle is not running around. It has hardly no power and I smell something under the hood from time to time burning it’s kinda like an electrical smell. I’m not sure. I’m not a mechanic. I’m a [XXX]. I’m a [XXX]!!! but I have to have a way back back-and-forth to work and I cannot drive this vehicle. I have been driving it to work and just straight to home and that’s only like a mile from the shop but I need a replacement vehicle I need to sell mine at wholesale value as you guys said you would that would be greatly appreciated. God bless you guys. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11722698 — an unverified report by a vehicle owner.
Hello, I has problems driving my car like by brakes braking out of nowhere. There was even a couple times I felt like the car swerved, even though I did not do anything to the steering wheel. Then I found out I had a recall that said not to drive the car because it was dangerous so I parked it in my driveway and I have not driven it for many months as I’ve been getting rental cars. Eventually, I brought it into Antelope Valley Chevrolet and they told me they were going to fix it but then they actually told me that I had to pay around $1000 for a part that I found out later only cost under $100 and takes three minutes to put in. This is apart from Chevrolet and not some knock off from China that I found for under $100 online. So I’m a little upset that I came in for a recall and they’re trying to get me to do a repair for almost $2000. They never even offered me a rental car and they’re threatening me saying that if we don’t move forward with it, they’re gonna charge me $50 a day for storage. I feel like they’re intimidating me to try to make me traded in for a new one, but I am not ready to get a new one. I just want to get my car on the road again.
NHTSA complaint #11722325 — an unverified report by a vehicle owner.
To NHTSA, I am reporting a serious safety defect in my 2023 Chevrolet Tahoe purchased from Criswell Chevrolet (Gaithersburg, MD). Defects include a documented brake system failure while driving and repeated electrical/shift faults preventing shifting out of Park. The issue is ongoing even after the dealer/manufacturer stated it was fixed. Key events: Feb 3, ~12:45 pm: While traveling ~35–39 mph on a five‑lane road, brakes failed. I slowed by coasting uphill and using maximum pedal force to ~5–7 mph before stopping. I have video of the incident and two other times this has happened with pictures as the car was in park. Three prior start-up incidents: All dash lights illuminated (including brake failure and Forward Collison System Unavailable); vehicle stuck in Park. First required towing; dealer could not replicate despite reported stored codes. Subsequent event stranded my family. I have notified Chevrolet and the dealer; their offer does not address safety or recurrence. Please record this complaint, assess broader risk, and advise on related recalls/investigations. If there is a path forward to ensure the safety of my family, please respond with that guidance. My phone number is [XXX] .

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Control algorithm issue. Unexpected acceleration. Not confirmed by dealer. I experienced it twice. Google Gemini sems to know about this. No inspections performed. No warnings. There is a safety issue with the 2026 Chevrolet Tahoe adaptive cruise control. My observation: On a previous drive, I used the adaptive cruise control with it set at highway speed. I disengaged it as I got off the highway using the brake pedal and arrived at my destination via city streets. I turned the vehicle off, exited and locked it. Later, I re-entered the vehicle, started it and began slow speed maneuvering (<5mph) in my driveway, where in, I accidentally bumped the cruise control “Resume” switch, at which time the vehicle began to accelerate, unexpectedly. I stepped on the brake to regain control. No accident occurred. This happened a second time upon my return from the local supermarket. In my opinion, the cruise control should return to the OFF mode when the engine is turned off and not remain “On” and ready to “Resume” after the engine has been cycled. The current operating mode is unsafe.

Vehicle taken into dealership for maintenance, after car received cars system software malfunctioned. Display screen went black and states "return to dealer. failed update" due to this issue I don't have access to car settings with most features are unavailable. All warning chimes such as turn signals, park sensor warnings, lane departure warning are inoperable. Had drove miles with turn signal on causing traffic disruption on neighboring lanes.

The vehicle has service driver assistance system warning. The seat vibration is not working and I believe there are issues with the sensor and or harness. There have been recalls on previous years of this vehicle for the same thing. There have been a wave of these lately, according to the dealership working on the vehicle. Parts availability is currently low because of this resulting in longer repair times. This is a key safety feature of the vehicle and must be repaired quickly. Unsuspecting users may expect warnings before collisions that may not happen.
NHTSA complaint #11716133 — an unverified report by a vehicle owner.
Vehicle lost all braking capability while in motion. Vehicle rolled to a stop with no brakes with warnings for brake system failure, no front collision active. Upon restarting the vehicle the warnings didnt not go way for 1hr. 2 hours later the warnings cleared from the information system but codes remains. Vehicle was taken to Uptown Chevrolet, Slinger WI and was informed of a bad battery as the "cause" of the issue. A bad battery should not result in the loss of braking capability on any vehicle!
