Lemberg Law is investigating reported vehicle owner complaints for the 2021 GMC Yukon. There have been several complaints regarding engine problems, more specifically with the engine lifters. This is the mechanism that sits between the camshaft & cylinder valves and actuates the intake and exhaust valves.
Vehicle owners have reported engine issues to complete engine failure on the NHTSA website.
A vehicle owner from Virginia stated:
“Engine failed on my new vehicle. GM is aware of faulty lifters produced over roughly a 3 month period. My vehicle has been confirmed to have those faulty batch lifters. At this time GM is only replacing lifters on the side of the engine that failed. The local dealership is having 2-3 of these come into the service shop per day. This is a major problem and I am being told it could be 2 months before I get my vehicle back. When I get the vehicle back I want it fixed properly and safe to drive. I don’t want my family broken down on the side of the road due to GM knowingly not replacing a faulty product let alone the inconvenience of not having the vehicle again for repairs.”

Another owner from Alabama left a similar complaint on the National Highway Traffic Safety Administration complaint database: “GMC Yukon Denali SUV 2021, push rods and lifters in motor are bad, this could have cause an accident due to SUV stopping in traffic or on the highway. Please help with this safety issue. The GMC Denali SUV 2021 only has 7000 miles on it, it new.”

2021 GMC Yukon XL Denali 6.2liter engine. Needs a new motor at 86,000 miles. Went to the shop twice in 70-75,000 mile range with “knocking noise” complaint. Dealer did not determine the problem. Dealer quoted 17,500 for new engine and GMC agreed to 50/50. So, a new motor will cost us 9,000 on a 3 year old vehicle. What options do we have?
My 2021 Yukon Denali with 23,000 miles on it died on a Highway, it needs an entire engine replacement. The tow truck driver could not get it into neutral, or took a team of senior GMC mechanics to get it into neutral, with a special tool and a sequence of buttons that has not been put anywhere in the user Manual, very concerned for my safety if the car does that again on a highway, if I keep the car. The car has been in the shop for a month and they do not have an estimated date of completion. I have asked the dealership as well as GMC What my options are as getting my car replaced as I do not feel safe in it, or an extended warranty, they keep saying they are working on a warranty, that should be the very least they do on such an expensive vehicle to die completely at 20,000 miles.
