    2025 Tahoe RST crooked tailpipes

    Hi - We had the similar issue on our brand new 23 Denali. When I showed the service writer at the purchasing dealer he said it was in spec so I showed him one finger in-between rear fascia on right side and three fingers on other. He gave up and the tech heated the exhaust and bent it into the...

    23 Yukon Denali XL Stock Air Ride Issue

    Hi, Trying to get some additional experience/info to see if I’m off base. Just recently our 2023 Yukon Denali XL will sometimes adjust the air suspension to its highest setting while driving.

    2023 Yukon Denali Transmission Issue

    Hi – We picked up our 23 Yukon Denali XL last week. It came with 3 miles on it and we still have under 100. When accelerating at slow speeds, like you would pulling away from a suburban stop sign or just in traffic it seems to hunt for a gear coming out of 2nd gear. Sometimes it’s coming out of...

    Hi – Checking in to see if there was any solution to this problem. We finally picked up our 23 Denali XL after ordering 10 months ago. Vehicle came with 3 miles on it and we still have under 100 right now. When slowly accelerating (like you would on an average suburban street) there is also a...
