Chevrolet Suburban adaptive cruise problems

Filed Oct 14, 2026 · Engine · AZ

Driving our 2024 Suburban, 6.2 L engine, on a 2-lane highway in southern Utah, traveling on cruise control at 70 mph, felt 2 hesitations (jerking movement), and turned off cruise control. Immediately after, heard knocking/thumping sound in the front of the vehicle, followed by a whining sound that got louder. Immediately found a turn-off from the highway, pulled in, and engine died while vehicle was still in motion. Attempted starting again and would not start. People stopped to help us and tried to jump vehicle without success. Suburban was towed to a Chevy dealership and we were told the Suburban's engine seized. In researching this issue, we came across the federal safety agency's investigation case EA26005. Our VIN does not fall in to this recall.

I was driving south on Highway 395 with 2 of my friends on our way home from vacation, which is a 2 lane road in the mountains. About 45 miles north of Victorville, CA. As I was accelerating, my vehicle all of a sudden dropped adaptive cruise control, the engine light started blinking, traction control errored, and I got a service ESC message on the dash. I let off the gas a little and everything seemed fine but when I reapplied pressure to the gas pedal the engine started making a loud ticking sound and had barely any propulsion. I had to keep going and was luckily able to find a safe place to pull off the road (which had many blind curves and minimal shoulder space along the highway). Had there not been a safe place to pull over before the engine completely died we could have been hit by any of the many semi trucks traveling on that road. After waiting 2 hours for a tow truck and having the vehicle towed to the Chevrolet dealer in Victorville, I was provided a small SUV rental vehicle to drive the remaining 150 miles home while I left my 2023 Suburban High Country for them to disassemble. When I called the next day they verified there was a Rod Bearing Failure inside the engine and they were submitting to GM for engine replacement. There were NO symptoms before the engine failure happened.

I have had my cruise control set and my car will slam on the brakes with no vehicles in front of my car or on each side. This has happened multiple times, it doesn’t matter if I am going 40MPH or 60+MPH. I have taken it in and they say there is nothing they can do for the issue. I’m worried for the safety of myself, my family, and my unborn child. As well as any cars around (behind me potentially) when this happens. I do not want to unintentionally cause an accident.

The contact owns a 2021 Chevrolet Suburban. The contact stated while driving at an undisclosed speed, the Forward Collision Avoidance system activated and abruptly applied the brakes, dramatically reducing the speed of the vehicle. Later, the contact stated that while driving at an undisclosed speed with the Adaptive Cruise Control activated, the vehicle inadvertently accelerated, requiring the contact to depress the brake pedal to avoid a collision. The vehicle returned to normal functionality, but the failure became a regular occurrence. The Forward Collision Avoidance warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the Forward Collision Avoidance warning light and the Adaptive Cruise Control module. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 28,000.

Automatic Emergency Braking system activated at ~77mph. Essentially I had started braking appropriately and at about the same time the AEB system seemed to conclude more breaking was needed. This led to brief loss of vehicle control when brakes COMPLETELY LOCKED at high rate of speed ~77mph. According to vehicle manual this system should not activate at speed great than 50mph (photo attached). This is dangerous because i could have lost control and/or someone behind me could smash into me. My vehicle does not have adaptive cruise. Vehicle and other systems otherwise work perfectly. As a side note the extreme brake application at high speed caused cargo within the vehicle to slam forward and destroy the windshield, in addition to being a scary event.

*From day one of purchase there is a random, frequent loud buzzing/whining through the speakers(with our without the radio on). Dealership had no idea how to fix and Chevrolet said there was no known issue, so no help. *The running lights constantly short out. We continually replace them and they short out again! *We have replaced all four door handles! Cheap chrome plastic is not going to hold up. These should actually be metal to insure holding up! *The tires seem too big since they rub the fender well if you cut sharply to either side. You can actually hear them rubbing on the well as you cut hard to either side! *The dash cracked about five years after we purchased it. We kept it under our carport and this cracking was unacceptable! I called Chevrolet and they said there was no known issue or recall. We continued to ask our dealership to look for recalls on this. *There was a recall on our passenger side airbag. We tried to get it replaced and were told, no they could not. Takata went bankrupt, so sorry, Chevrolet will not replace air bag for you! *After a few years of not being able to use our front seat due to safety issues Chevrolet would not fix(defective airbag), we decided to save and get the airbag and cracked dash replaced on our own. Unacceptable! Proclaimed recalls should be tended to by manufacturer! *The cruise control just stopped working one day early on, no recall--not surprised:( *The fuel tank is cutting off at the pump as we try to put gas into the tank. This is problematic as the vehicle will not run without fuel! Currently fighting with this and contacting dealership to see if they can help at all. Everyone we know who has a Suburban or Tahoe has these same problems! These are all widespread problems/design flaws. Please look into these issues to make a better product!

I purchased my vehicle after the recall 19V‑645 regarding the brake pump was issued. My vehicle was a part of that safety recall, and the module was reprogrammed in September 2019 (N192268490-01). The pump has not been previously replaced according to service records. I purchased my vehicle from a dealership in April 2021. I recently (late 2023) started having issues with my brakes, having increased brake pedal effort, a hard brake pedal, and increased stopping distance. I have had the brake assist alert come on several times. The issue happens more frequently at lower speeds. My park assist alert also comes on regularly when applying the brakes. I have taken my vehicle to GM several times regarding the park assist issues, but they have only cleared the computer codes and cannot figure out why they keep coming back, as there is no detectable issues with the system. I have also brought my vehicle in due to the adaptive cruise control, as it has also caused issues while using it. It will often apply brakes if it detects a vehicle in another lane while driving, causing the vehicle to “slam” on the brakes going at high rates of speed (I.e. driving on the interstate at 80 mph) and has nearly caused accidents, as the vehicle becomes hard to control, and the risk of following vehicles not having the reaction time to avoid a rear-end collision is increased. My particular vehicle does not have an option to switch between regular cruise control, and adaptive cruise control. After talking with GM, they informed me the only way to “fix” the issue is to completely replace the module with an updated module that allows the option to turn off the adaptive cruise control, which is quite costly to the consumer. My vehicle is currently at a GM service department, and has been diagnosed that the brake pump has failed, and needs replaced. They are claiming that it is not covered under the recall. It is not covered under GM’s extended warranty due to mileage restrictions.
