Chevrolet Silverado 2500 adaptive cruise problems

Filed Aug 7, 2026 · Acceleration, Driver assistance · AL

Safety Issue. The raised cruise control speed set button on the steering wheel is prone to being touched when rotating the steering wheel while making sharp turns when driving through parking lots at low speed. If the distance cruise was previously set at say 45 mph the last time it was used, and the set button is very briefly hit upward when rotating the wheel through your hands to the left, it can inadvertently cause the truck to start accelerating to that previously-set speed. The cruise button needs to be programmed such that at certain steering angles it will not respond to inputs. This is very dangerous. I ave had this happen to me at least 5 times. Hitting the brakes stopped the acceleration. I reported it to the dealer as a potential engine surge but they could not reproduce it. I just recently realized what was happening. I believe this can easily be addressed by a steering angle lockout of the button. Other issues: Drivetrain vibrates occasionally and shifts very hard (drivetrain literally slams through gear change) when leaving driving from a stop a slow speeds. Dealer cannot replicate. This diesel truck gets very poor mileage possibly from spending too much time in regeneration mode. Truck is super sensitive to fuel. Mileage varies drastically from fill up to fill up depending upon station. I believe the fuel cetane content affects regeneration in unexpected ways. I buy fuel at name brand stations but mileage varies drastically from vendor to vendor. Mileage average goes down to about 11 mpg much of the time due to time in regeneration. Dealer has no comments. I know HD trucks don't have official mileage ratings but this is just crazy. I drive light on the accelerator. Rarely achieved up to 21 mpg but average mileage runs about 11-12. I believe this to be a fault with these trucks as I have read complaints from many others. The infotainment system frequently loses all audio, including turn signal sound, nav. GM has no fix. Possibly software.

In December of 2024 Safety Recall N2424440-01 was applied. On the morning of Saturday August 23, 2025 while driving on a two (2) lane highway with the cruise control set to 60 MPH the vehicle “shuttered” then the shifted into a lower gear locking the rear wheels bringing the vehicle to an almost complete stop in very short distance. I was able to pull off the road out of traffic. Since it was a light traffic morning, no one else was close limiting the risk to me. Had there been anyone behind me they would have been caught off guard by the sudden stop with no signal of brake lights showing. The vehicle is in “limp mode” and will not exceed 35 or 40 MPH. The vehicle will shift in to park and neutral. It will not move in reverse forward. The vehicle has been transported to the nearest Chevrolet dealership for diagnostics and service.

Owner from brand new (16 miles) multiple complaints through ownership of harsh shifting, jerky throttle on and off, excessive engine braking, and have been stuck on the side of the road 3x due to the same situation. Never was a code thrown so I was continuously told there’s “nothing wrong.” On [XXX] I was driving [XXX] out of Denver making the climb towards [XXX] to home. As I had my cruise control set at 65, out of nowhere my truck locked up what seemed to be the rear wheels completely, causing my rear end to sway violently. I immediately slowed down and pulled over with no indications or lights being illuminated on my dash. I turned the truck off and let it sit for 10 minutes and restarted it. Having no issues I signaled back onto [XXX] and the truck accelerated to nearly 65 with no issues. As I hit 62 on the dash it again locked up the rear tires. I again pulled over, this time questioning what could be causing this, knowing the first time indeed was what happened. I put my truck into park, and still had no warning lights or check engine light. I then put my truck into neutral and then clicked the auto button thinking maybe something with the rear end is locking my brakes up. Upon doing so I again entered the roadway, big mistake on my part as this time upon reaching 60+mph all 4 tires simultaneously locked up. How I didn’t roll, I have no idea. Easily the scariest set of events I’ve ever faced while driving and that’s considering all of the insane drivers on our roadways today. I literally lodged a complaint with Chevrolet the same day I bought this truck before ever even leaving the dealers lot, and have had zero communication from them other than myself reaching out. They have ignored the problem literally from day one and it easily could’ve cost me or someone else their life. I’m appalled that to date they are still selling these trucks, replacing the valve bodies with the exact same faulty ones, and allowed to put others in danger constantly.

Truck is under 105000 miles and needs a transmission due to a failed torque converter. First starts with erratic speeds in cruise control mode that is unsafe then will not shift into overdrive causing overheating issues.

While using adaptive cruise control, the system can detect a vehicle and immediately apply the brakes or slow down. In some cases, it may detect a vehicle (the vehicle icon appears) and trigger an immediate red collision light flash, followed by automatic braking. However, during these events, there were no cars ahead of the vehicle. There was no obstruction of sensors or cameras, and the incidents occurred in various weather conditions, including rain, snow, and clear days, both during the day and night. If the road is slick or slippery, this could potentially lead to a loss of control. Additionally, if another vehicle is following closely behind, it could result in a collision.

I was stopped at a stoplight, when the light turned green, I let off the brake and the truck took off at full throttle. I never even had time to touch the gas pedal, it went from 0 to 60 in less than 1/2 a block. I thought it may have been a cruise control issue and tried several times to turn it off, but didn't slow down one bit. When we got out of town, I let off the brakes and it continued to gain speed until we hit 75 MPH. I again engaged the brakes, turned a corner to get off the road, and when I turned, the truck went back to normal. It was like a switch was turned off. The entire incident lasted about 5 minutes, but if we had snow or ice on the road as is usual this time of year, it surely would have resulted in a serious accident.

While driving on cruise control around 70 MPH my check engine light came on. About 20 seconds later an alarm sounded and a message in my dash saying transmission fluid hot and to idle engine immediately. I immediately pulled over and called the dealership where I purchased it and had all services. Although the service representative I spoke with said it probably was just a sensor, I elected to have the vehicle towed to the dealership for repairs. The next day the same service representative advised me that my torque converter went out causing my front pump and transmission module to go out and I needed a new transmission assembly. My vehicle has 43,000 miles and I rarely tow a 3,000 lb boat. I was then told my 5 year 60,000 mile warranty expired 26 days prior to this issue. After researching, I found that this appears to be a problem with the 1500s. The dealership is charging $6,100 and gm is only willing to cover $1,800.

While driving my vehicle on a city street at approximately 45 miles per hour, I set the cruise control to maintain the 45 mile per hour speed. After less than 60 seconds, the cruise control cause the vehicle to accelerate rapidly to 85 miles per hour. Stepping on the brake at first did not cancel the cruise control. When it did finally cancel, I continue to drive manually. The cruise control then took over again and cause the vehicle to accelerate rapidly, exceeding the speed limit. Once again, the brakes were applied and the cruise control cancelled. The cruise control was turned off at the main switch on the turn signal stem. Later on, the cruise control was turned back on and tested again with the same results. After the third attempt to set the cruise control at 45 MPH, the cruise would not set at all. The vehicle was taken to an independent repair shop. They were not able to find any specific electrical problems. But they did indicate that the cruise control module itself would probably be at fault. If the cruise control switch is left in the on position, but the cruise is not set, it may randomly take over the throttle and accelerate or sometimes hold its own speed for several minutes at different rates of speed. This creates a hazardous situation for all occupants of the vehicle along with others that may be in the path of the truck when it randomly accelerates. As of the time of this writing, a solution has not been found to correct this situation.
