Owner report 11721852 · 2026-03-03 (March 3, 2026)
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 d…

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!!

Owner report 11726900 · 2026-03-25 (March 25, 2026)
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 workin…

Engine started "ticking" for a bit. Then sounded like marbles were in the engine. Loss of power and engine light came on. Dealer says my 6.2 engine failed and new one needed. Less than 9000 well cared for miles!

Owner report 11718167 · 2026-02-15 (February 15, 2026)
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…

Owner report 11750159 · 2026-07-13 (July 13, 2026)
I was on the interstate. Initially I heard a faint rattling sound. I turned off the radio and AC to listen more closely; the sound was not audible. But then traffic came to a standstill. As I slowed, that barely audible noise began to sound like something boiling in the engine. The temperature and pressure gages were all in normal operating ranges. I pulled to the shoulder of the interstate and checked under the hood. I noticed a distinctive squeaking sound although the fan belt was intacted in running true. There was no sign of any flu…
