Chevrolet Silverado 1500 adaptive cruise problems

Filed Nov 5, 2026 · Engine, Transmission · IA

On October 27, 2026, my 2022 Chevrolet Silverado 1500 LTZ with the 6.2L engine suddenly lost propulsion on Interstate 80 near Atlantic, Iowa. The mileage was approximately 62,000, although I am uncertain of the exact mileage. I had driven approximately three hours after leaving my hotel that morning before stopping at a gas station. When I restarted the truck, the engine barely turned over before starting. No engine warning lights came on at that time. I continued onto I-80. Approximately five minutes later, the truck began losing speed with cruise control engaged. I disengaged cruise control and pressed the accelerator. The engine revved, but the truck did not accelerate. The check engine light came on just before the truck shifted itself into neutral. I coasted to an off-ramp, and the truck would not restart. It required towing. The sudden loss of propulsion at interstate speed put me and surrounding traffic at risk because I could no longer accelerate or maintain speed. The dealership inspected the truck and told me it failed what they described as a “propulsion test” and was included in a recall. The specific internal component that failed is unknown to me. Whether the failed components have been retained and are available for inspection is also unknown to me.

On July 4, 2026 while driving with my family up a two lane state road headed to the lake cruising 55mph the engine blew and locked up with no warning, no check engine light or anything causing me to almost wreck and leaving me and my family stranded in a dangerous situation for a moment. I drive out of town just about everyday for work so my truck is set on cruise control most days through the week making multiple long distance trips a month so the mileage racked up fast for me causing me to go right over my warranty when this happened so I can’t get any help with it. Even knowing the issue right now with the 6.2 they will do nothing.

In reference to 2024 Chevrolet pickup, 6.2L engine, 10 speed transmission. The vehicle is available for inspection upon request. I believe the transmission is going into "partial lock-up" at full/highway speed. When traveling on highway with cruise control engaged, the vehicle suddenly acts as though the brakes are being strongly applied, slowing the vehicle at a very rapid rate, down as low as about 40 MPH. The vehicle slows quickly enough that the driver and passengers are thrown forward to the extent allowed by the seat/safety belts. The issue terminates itself at various times. The vehicle has been inspected by GM mechanics several times, but they cannot find the problem. There were no warning lamps, messages, service engine lights, etc. This has occurred on at least five (5) different occasions. The first occasion was at approximately 7000 odometer miles. The vehicle now has 25,100 miles. All incidents have been reported to GM dealership mechanics.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the message that the rear seats were occupied and that the windows were rolled down was displayed, which required the contact to press the OK button. The vehicle was taken to the dealer where it was purchased, but no assistance was provided. The traction control and the ABS warning lights were illuminated while depressing the brake pedal. Additionally, the cruise control mode was inoperable. The contact replaced the brake pedal position sensor independently, and the vehicle was taken to an independent mechanic, who reprogrammed the sensor. The contact stated that after the repair, the brake lights erroneously illuminated while the vehicle was turned off, causing the battery to drain. The contact disconnected and reconnected the battery, which reset the vehicle; however, the failure recurred. The vehicle was not further diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 110,881.

While driving at highway cruising speeds, the vehicle began showing abnormal RPM fluctuation/surging at steady speed. The RPM would repeatedly move up and down even while maintaining a constant speed, including when cruise control was used. There were no warning lights or dashboard messages at the time the symptoms first appeared. The suspected failure is the torque converter/torque converter clutch in the automatic transmission. After diagnosis, I was advised that the torque converter failure contaminated the transmission fluid/internal transmission components, and that the transmission now requires replacement. The failed transmission/related components may be available for inspection upon request, depending on repair timing. This condition created a safety concern because the drivetrain was not operating normally at highway speeds, causing inconsistent power delivery and concern that the transmission could slip, overheat, fail further, or leave the vehicle unable to maintain speed in traffic. A sudden loss of propulsion or worsening transmission failure could increase the risk of a crash. The problem has been diagnosed by a transmission repair facility. The vehicle has not been inspected by the manufacturer, police, or insurance representatives. No crash occurred. No injuries occurred. No warning lamps appeared before the failure. The first noticeable symptom was the RPM flutter/surging at steady highway cruising speed. The exact internal cause is unknown, but the best assessment is torque converter/torque converter clutch failure resulting in contamination and failure of the transmission.
