GMC Complaints

The torque converter of transmission went out on my 2019 GMC Sierra 1500 Denali with only 62072 miles. My safety has been put at risk daily, from intermittent shuddering and loss of power. My vehicle underwent a multi point inspection at Earnhardt Buick GMC confirming I will need a complete transmission assembly estimated to be around $7100. There were no indications or dash lights, the only reason I brought it in is from hard shifts, and intermittent shuddering.

Vehicle shifts hard from 1st and while driving when getting up to speed from 2nd gear and 3rd, etc. Happens every time it's driven.

All power shuts off while driving. The transmission dis-engages, the power steering stops working and the infotainment system turns off. The power steering powers off even when sitting in a parking spot while everything else is on. I've owned this truck since 2019 and this has always been an issue, especially when taking a left through an intersection. I keep checking for recalls, but nothing shows up and I find that extremely hard to believe. I'm contacting you now because the issue has gotten worse, everyday worse.

This is a 2016 GMC 3500 Denali truck with 70,000 miles on it. The Bosch fuel pump threw metal shavings into the fuel system. This is a known issue with GMC trucks with a Bosch CP4 fuel pump for 2011-2016. The engine suddenly quits running leaving the driver without power steering or power brakes. It happened to me when pulling a 14,000-pound 5th-wheel RV. Fortunately, I was on an interstate outside of Grand Junction CO and the road was flat. If I had been in the mountains going downhill and the engine quit I'd likely caused an accident perhaps fatal. GMC quoted me $16,000 to repair. Again, this is a known issue at GMC but they refuse to do anything about it. GMC Dealership in Grand Junction performed the analysis and advised me to drive it home to Phoenix. I got 60 miles when the engine quit. Cost me $1,600 to get the truck returned to my GMC Dealer in Phoenix and another $1,600 to get my trailer back home.

Power steering reduces and the temperature gage wont work and the fan is extremely loud so it decreases the steering and increases the fan so it can cool down the engine. Others have submitted a recall form for this same problem
