Add Failed Rocker Arm to the list...2022 Tahoe 6.2L under 6k miles!
No noticeable feel in loss of power or rough idle prior. Lots of warning lights came on, all of them, including things like traction control disabling. So many occurred I could not remember them. Power loss was very quick from that point. My wife thinks in hindsight that she heard the engine was...- Rennsport

2021 Tahoe left us stranded 3 times first year
The lifter issue/failure has NOTHING to do with first year model year! And how GM is handling it, alone is enough to vote with your walking boots! I also have a deposit on a Sequoia (and will take my chances with them vs GM). My guess is GM is hoping to buy time as they go electric and just hope...- Rennsport

Add Failed Rocker Arm to the list...2022 Tahoe 6.2L under 6k miles!
GM is not the GM of years past once they went to the Dynamic Fuel Management (DFM) system. I have owned 6 GM vehicles (4 of them Tahoe/Suburban), so safe to say, I am a loyal repeat customer. Not anymore! I was left stranded on the first day of a family trip, after a nerve racking experience of...- Rennsport

Transmission/Shifting Won't work 2021 Yukon XL Denali
Well Mannyp02, now I have the same problem. 8k miles on a 2021 Tahoe Z71. I was driving about 35mph on a short drive on a flat street just cruising and the first thing that happened was my radio sound dropped to a low level for about 15secs and then came back to normal level, then I press the...- Rennsport
