My worst car ever.... My first one (in Europe) was a Citroen 2CV (wobbly ugly duck). Even that clunker was better. Why ? While on vacation West, Utah/Colorado, the instrument gauge display went BLANK. No speed indicator, pulling a 28 ft travel trailer. I never had a car before with no speed indicator.....Dealer in Colorado Springs said would be a lengthy repair and said to make an appointment. We are travelling....contacted Onstar and GMC furious. They advised me to go to any repair shop to check. Across the dealership was a Midas. They plugged in their little PC: hundreds of alerts mostly parking sensors related,m memory overload. I told them to delete all alerts. A miracle, the display came back to live. The most likely root cause: we drove hundreds of miles on BLM off roads, gem hunting, lots of dirt. That is what one does with a 4x4 right ? To clear the undercarriage and sensors each evening we drove throughg a touchless car wash. all clean for a next day trip. GM claims: GMC® Sierra 1500 - Sophisticated Technology Not sophisticated enough to see that sensors were cleaned every day. By the way, the cost by Midas was $0.00 nada. I dont understand that an onboard computer can be programmed to just shut down the most important display, the instrument cluster with the speedometer.

The last week of 2022, I bought a new Sierra 1500 Denali, 6.2L V8 engine. Salesperson showed me all functions, including setting up the gap for the adaptive cruise control. The adaptive cruise control would never work. I just returned from the dealership: "Oh, it was not installed, that is part of the high end package. So...all talk about high end Sierra trucks, such as the Denali, having "adaptive" cruise control: No, not correct. There is only old-fashioned cruise control. The feature to set up up the gap in 1-2-3 increments means NOTHING. $72,000 for old fashioned cruise control....what is wrong with GM ?

Hi MATT99199, just picked up my new 2022 Sierra Delani. "If equipped"..". No 12V anywhere. I need to power 1 small RV back up/rear view driving camera display as well as a small Realtime forward camera. both outfitted with cigarette lighter plugs. Your idea is brilliant. Where exactly dou you get to the 12V at the back of the console ? thanks Rob

Am about ready to drive my new truck through the dealers front window. Very distracting when pulling a travel trailer, the navigator screen flips to password required. Have to take my eyes of the road to go back to navigator screen. Every darn 15 minutes on a 12 hour trip. CRAP
