We have had my suburban since April 2021 and it’s been at the dealers for 22 days. This is two malfunctions regarding the DEF pump and they are replacing it a third time. Has anyone else had issues with this? I advised them I was concerned because this is a brand new vehicle and after our warranty, granted we have lots of miles left on it, is this going to be a life long issue for our vehicle. We bought diesel to hopefully maintain and last longer. Irritated I am paying on this vehicle monthly and it’s been at the dealers this long.

Hello - I bought a Tahoe High Country Diesel back in May and had nothing but problems. I’ve had to have the diesel converter, sensors, Def pump, and other items replaced. Additionally, the drain tubes for the moonroof were defective and was draining water under the driver side floorboard. I was only in Possession of the car for 18 days since ownership and only put about 400 miles on the car. The car now has 1500 miles due to the dealership putting on the miles trying to fix the diesel issues. I got the car back last Monday and unloaded it to Givemethevin.com. I lost about $1,500 but it was worth it to get rid of it. This was very frustrating after spending 80K and getting a poorly built vehicle. My advice to readers is do not buy the diesel because Chev obviously has some serious flaws that they do not know how to fix. Also, the manufacturing process has some serious defects with their QA process.

Thank you so much for your response. If this continues we will file a suit. I hate that this is happening because the vehicle itself is nice. But yes for 74k I don’t want a lemon.

Leaking sunroof which leak on almost every vehicle that has them is not specific to the GMC , Chevy nor does that have Nythinf to do with it being a diesel model.

DEF, well you got a bid one. Look at what's happening with labor these days. Inferior help and people being paid to sit home. NOBODY WANTZ TO WORK WHWN THEY CAN GWT ALMOST SAME WAGES SITTING HOME!!!. This is not auto industry either qbviously. Supply chain issue.

I have a 2021 yukon dmax and love it! Knock on wood not one issue.
