Odd / harsh shift from 1st to 2nd
I have '06 Yukon Denali with the 6.0L . Started having an issue yesterday after about 80 miles of driving of a harder than usual shift from 1st to 2nd gear when accelerating from a complete stop.

Think I got a leak in the air ride....
On any given day, the air ride suspension in my Denali would normally pump for about 5-8 seconds at start up....no problem... Well, after towing the boat last week on a 20 mile round trip to the lake, the compressor now runs for 2 MINUTES on start up!! After a day or two, it's still doing the...- DeepSeaFish

Cranked up this morning and noticed the low tire light on. Pulled up the tire pressures in the display and the R/R is showing 23 lbs. Got out and checked for a nail in the tire ( new Michelins! ) and can't find anything. As I'm driving to the station to air up, the pressure climbs one pound and...- DeepSeaFish

Heated seat problem....
The bottom seat cushion on the passenger front seat has stopped warming when the heated feature is turned on. However, the backrest warms up fine and driver's seat works fine on both seat bottom and backrest. Is this an issue with the heating element in the seat bottom? Thanks.- DeepSeaFish

Seems like every 15-20 cold starts or so, I'll get that one start up where something jolts the truck a little making a loud thumping sound right as the engine fires. There are no codes stored in the system and everything else is...- DeepSeaFish

Air ride suspension question
Just out of curiosity, how often should the air ride be kicking on under normal everyday driving? I'm usually the only one in the vehicle and I'm not towing yet, but will be this spring and summer. When I acquired the truck last month, it kicked on about every day at start up for about 10...- DeepSeaFish

Headlights / dash lights flicker...
I have noticed a few instances at night that my headlights and dash lights will flicker simultaneously just a bit, especially just after a cold start. I drove about 40 miles round trip the other night and this happened 3-4 times each way. I've read on several boards that this is known GM problem...- DeepSeaFish
