2026 Chevrolet Tahoe Complaints

While driving down [XXX] the car started making a weird noise as we slowed down for an upcoming light. The light changed and as we started to drive again the check engine light came on and I lost power steering. I was trying to navigate the car off towards the shoulder but the car was hard to maneuver, but was able to move into the right lane. I had to drive the car slowly as to not stop the engine propulsion and stalling. But had no luck once we reached the intersection on [XXX] and [XXX] . At this point the car just died. Nothing was working. Hazard lights didn’t even work at one point. This situation left me and my family in the middle of traffic on a busy highway road. The only thing we had in our favor was the car stoped right at a red light so traffic would have to slow down every so often to the stoplight. We had to have the car towed off the road at around midnight and they took it to the dealership. The engine had a complete failure (found out after the dealership took apar...

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.

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.

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 r...

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” a...
