Automatic Emergency Braking problems of the 2024 Chevrolet Traverse

Emergency brake engaged while driving in reverse causing the vehicle to abruptly stop 3 times leaving the driveway. This continues to occur as we left the house moving forward decelerating the vehicle. My [xxx] infants were in the vehicle causing them to scream, and this defect could have easily caused a crash. I no longer feel safe driving the SUV. We proceed to call the dealership we purchased it from (rick hendricks Chevrolet of naples) spoke with management the guys name was jack. He said this is an ongoing issues they are working on and told us to bring it in. I’m not driving this vehicle on the highway an hour away so we are now escalating the situation to headquarters.

"phantom braking" with over 13 events the 2024 Chevrolet Traverse lt unexpected and abrupt activated the automatic emergency braking (aeb) system when there was no obstacle, vehicle, or collision risk present! if an mac truck was behind us tailgating at the time we would have been killed! the dealer is downplaying the issue acting like they have never seen this before. They question is we know what aeb is and how it works "we do!". On top of that the 2024 Chevrolet Traverse lt breaks are completely defective. Deal inspected them on 6/25/2025 then we purchased on 8/14 drove it for 2,290 miles and they claim the breaks needed replacement. So we paid for that and still the breaks make a bad grinding sound and it is hard to stop the SUV. Please investigate ;(.

We have experienced phantom aeb warnings and braking (60+ warnings w/o braking, around 10 brake activations) since owning the vehicle a little over a year now, purchased new. We took it into the dealer in may to have it addressed and they determined the aeb system was inoperable due to a defective front camera (windshield). After replacement and reprogramming, we picked up the vehicle and noticed a decreased sensitivity to our rear/side alerts and zero forward aeb or proximity alerts of any kind. Not car, pedestrian, object or wall. Forward aeb alerts were completely disabled. Additionally, the vibrating safety seat which was previously inoperable (we assumed our car didn't have it) was on and functioning for all side/some rear alerts. We took the car back into the dealer and after 5+ days they determined it was a "faulty batch of cameras" and they replaced the front facing camera again. Today, we picked up the vehicle, being told everything was tested and reset so functioning properly- with our 3rd new forward camera. Yet, the aeb system was clearly inoperable again, zero front facing aeb/collision/proximity alerts - even though all settings 'on. ' rear alerts still seemed delayed and less accurate than before we brought the vehicle in the first time. I returned the vehicle to dealer and demonstrated again. My service rep agreed - it does not seem like it's just the front facing camera and must be a larger issue electronic issue. To date, I've been in contact with gm corporate executive team and have very little real concern or amelioration of these qc issues with the vehicle. We have spent over 20 days in the shop within 12mo. They refuse to acknowledge that there significant defect with the vehicle to warrant repurchase. These safety issues are only part of what appears to be serious qc deficiencies that put my family at risk. My wife and kids are in this car 98% of the time. I have video documentation from both camera repairs if you want to see them.

On July 31st, while backing up on a clear road in rain the brakes locked suddenly. The brakes applied & a message saying emergency parking brake engaged. Must be manually released. This happened twice in a 30 second period before there was enough room for me to pull forward out of the spot. I called the dealership on August 1st to see if this was a known issue and they said no. Brought the car in on August 2nd. They scanned for errors & found a message lost communication with parking assist control module with 9 other error message. They said this was not a known problem and to them it appeared to fix itself but would let me know if there was any way to fix. Car has just been in for regular multi point inspection on July 24th. On August 20th went to get in the car but none of the key fobs would open it. Called two dealerships but neither could come up with answer. Chevy roadside was called & came to get into the car and ended up jumping it. At that time the battery was tested and it appeared fine. It was recommended to run it for a half hour. I ended up driving it for an hour with no extras on. On August 25th the next day I went to drive it the battery of this 1 year old car was dead. Called the two dealerships to see what could be done & was told to bring it in. Called chevy roadside assistance who dispatched someone to open the car and jump the battery. This person found the battery was not holding a charge & said nothing when I said I was driving it to the dealership. Got 3 houses away & a message that the brakes have failed. Press hard to brake popped up. In addition the steering locked up. I missed hitting a lady with a kid in a stroller by 6 ft but managed to get it to the curve & with 3 pushes into park. It was towed to the dealership. When it arrived at the dealership the brakes locked up so it would not back up off the flatbed. It had to be forced off. Dealer blames poor battery but can't explain July 31st or why battery readouts say okay.

While backing out of a driveway into an unobstructed road with no oncoming traffic from either side nor any pedestrians or cyclists approaching, the automatic emergency braking system applied the brakes and then locked up leaving the vehicle as an obstruction in the road. To disengage the locked brakes required a large amount of pressure on the accelerator pedal bringing the engine rpms up to a sufficient speed to disengage the automatic emergency braking system. Had there been traffic approaching what would have been an otherwise safe amount of time to bring the vehicle into the flow of traffic would have been insufficient and may have caused an accident. There was no warning indicating any of the vehicle sensors detected an approaching object or obstruction. This is the second incidence of the occurring in the last week.

I am writing to report a serious safety concern with my newly purchased. I believe this issue, if unaddressed, could lead to accidents. Specifically, when I am stopped at a stop sign with another vehicle behind me and the light changes to green, I begin to drive forward. However, as the vehicle behind me starts moving toward me, my car suddenly and violently applies the brakes. The force is so strong that it feels as if I've been rear-ended. This abrupt braking creates a dangerous situation as it increases the likelihood of me being rear-ended by the car behind me. It is important to note that I am in "drive" mode and moving forward, not in reverse, so I would not expect the car to brake under these circumstances. This issue is not isolated, and I have experienced similar sudden braking on several occasions, but this scenario is the most concerning due to the potential for accidents. I took the car to the dealership, assuming it might be a programming error. However, the dealership informed me that this is a known issue with this model, but no recall has been issued to address it. I strongly urge the ntsb to investigate this matter further, as I believe it poses a significant safety risk to drivers and passengers. Thank you for your attention to this issue.

Recurring failures related to brake system. When reversing, the rear brake assist system slams on the brakes for no reason even though no obstacles are present. This startles everyone in the vehicle and nearby traffic. On other occasions, the vehicle shows an error on the instrument cluster stating "rear brake assist unavailable". More recently, a persistent error began appearing on the instrument cluster stating "service brake monitor", indicating a failure of the brake pad sensor. On top of all of this, the brakes are noisy and squeaky to the point where it wakes up my neighbors.

On multiple occasions now this vehicle has applied automatic braking for no apparant reason. The vehicle has applied an extreme braking scenario. And applied the full brakes causing the vehicle to skid and extremely jar the interior passengers. This automatic braking was almost like driving the vehicle into a wall as it was immediately stopped. In the latest instance the vehicle behind me was barely able to avoid running into the rear of my vehicle.

The 2024 Chevrolet Traverse includes front pedestrian braking and rear cross traffic braking as part of its standard advanced driver assistance systems (adas). However, these systems tend to malfunction on rainy days when the sensors become wet. In such conditions, the vehicle may brake abruptly even when there are no hazards in front or behind. For example, while attempting to drive around a vehicle waiting to make a left turn at an intersection, my Traverse suddenly stopped in the middle of the intersection, incorrectly detecting a potential collision. Another frequent issue occurs when backing out of my driveway on rainy days. The system applies the brakes, mistaking raindrops for obstacles. Due to these recurring problems, I have deactivated the safety systems and now drive without them enabled. This situation not only creates inconvenience for me as a driver but also poses risks to other road users if the vehicle stops unexpectedly in traffic. Additionally, repeated hard braking can lead to premature wear of braking components.

Transmission issue: dealer was not able to replicate issue due to it only happening periodically. When putting into drive mode and going to accelerate it feels as if the transmission is slipping and give a big jerk. Also will sometime make a loud noise like tranmission is "dropping". Or when foots off gas peddle after going at a steady speed then go to accelerate again it will jerk. Dealership said that is normal as there is a "learning phase" which I've owned several new vehicles n never experienced this before. No warning lights have been shown. Reverse automatic breaking issue: several occasions while reversing vehicle will slam into park mode when nothing is behind me. Brought to dealer, dealer said to shut off the notification. However, I don't want to have to shut it off. Tech did experience this once while attempting to reverse vehicle. But service advisor said there is no fix for this issue. Very startling to anyone in vehicle when it quickly locks up.

1. When reversing, the emergency braking is very sensitive. On 6/20, it was pouring rain and every time I tried to back out the car kept slamming on the brakes thinking there was an object in the way. It also happened when we were leaving an appointment that same day. It wasn’t pouring rain, but rain was dripping down the back of the car and the car slammed on the brakes at least 5 times trying to back out. This also happened before when backing put of a parking spot and there was a shadow behind my car. The car kept slamming on the brakes thinking there was an object there. 2. Very jolting and unexpected movements. Not safe when trying to back out. 3. Unable to reproduce at the dealer. Took to the dealership on 6/20 after this happened. It was no longer pouring rain at that time, so was unable to reproduce the issue. 4. No inspection. The dealership did look at the sensors to make sure they weren’t pushed in or obstructed. 5. No warning prior to the issue.
