While driving down I35 South of wellington Ks in our new 2026 Chevy Tahoe we experienced a vehicle shift to neutral and no transmission correction available. Coasted to ditch saw “Service Transmission” notice and so turned off and on engine . Went to Derby Ks and Davis Moore Chevy in Wichita where staff removed the warning service notice on driver info and we continued to Molle Chevy in Blue Springs Mo. where they did diagnostic and only showed ambient air fault!! This is scary! We had no transmission and had to get off road safely! Please let public and our dealers know and recall all vehicles with this problem. We are afraid to drive this new 3,000 mile Chevy Tahoe.

We were traveling over 70mph on a Kansa state turnpike near Wellington, Ks. and all drive power was lost! Luckily, being in the right lane we then had to coast to the right ditch lane. We saw a message on driver’s info screen “service transmission”. Tried to shift off drive and back on..nothing. So, we shut the engine off and restarted and the message stayed on but we power managed to drive over 20 miles to a Wichita Kansas Chevy dealer called Davis Moore Chevrolet (recommended by first stop, Derby Kansas Chevy Co,) for solution. Gentleman did a shift on off key removed etc and the”service transmission” light turned off and we continued to drive to Kansas City. This is very dangerous!! We are now afraid it may happen again!! Losing all power while on road is dangerous!! Please respond to recommendations to driving this Tahoe and immediately send recall to us !! One should be issued. Also,let our repair dealer in Blue Springs Mo Molle Chevrolet know as we will be going there for repair needed on this brand new 3,000 mile Chevy.

The contact owns a 2026 Chevrolet Tahoe. The contact stated while driving 70 MPH on the freeway, while depressing the accelerator the vehicle shut off unintendedly. The vehicle was coasted to the right side of the roadway. While attempting to restart the vehicle, the vehicle failed to respond as intended. A dealer was contacted. The vehicle was towed to the dealer and was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 3,783.

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.

On [XXX] while driving home from work (5 miles) the engineer ne had rough starts while in auto stop at each light and stop sign. Not enough to cause huge concerns. Two days later on [XXX] we traveled to my mother in laws house 2 hours away. Upon returning home we noticed that the cruise control would not turn on, we pulled over and wiped the sensors even though the car was clean. 25 minutes later there was a metal on metal noise coming from the front end. The noise was heard when letting off the gas pedal. It sounded like a metal fan grinding at a high speed on a tin roof. We pulled over at a parking lot off the side of the road and opened the hood. When attempting to turn the car back on the noise from the engine was the same and it promptly shut down again. The car was towed and determined that the engine blown at 2,333 miles on the OBO. No warning lights ever came on and the oil pressure seemed normal. There are still no notifications on the Chevy app and it still says all is well. Even after the motor is replaced I will not feel safe driving my kids even to school. What happens when we’re driving to Denver for my daughters all state choir and it blows again? What happens if we are traveling at an interstate speed and it causes an accident? I do not want to have to replace the motor twice more just to have GM buy it back. This motor design is going to kill someone and something needs to be done. I have a finance loan of $101,000 for a dangerous car that I will never feel safe in and trading it in we will lose out on $4k in registration and somebody else will buy it and they will be in danger as well. A recall for a buyback for all with the 6.2 L Tahoe engine needs to happen. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
