On [XXX] while driving my 2021 GMC Yukon Denali to work, the vehicle suddenly lost power without warning. I had it towed to the dealership, where I was informed that the fuse pack needed replacement. Less than 36 hours after getting my vehicle back, I experienced another critical failure’while driving, the traction control light and check engine light came on, and the engine began making a loud clacking noise. Upon returning it to the dealership, I was told that the vehicle required a complete engine replacement. Prior to this incident, my Yukon had no known mechanical issues. However, despite the vehicle being only three years old and under GMCs 5-year/60,000-mile PowerTrain warranty, the failure occurred at 65,722 miles’just over the coverage limit. GMC has acknowledged nearly 900,000 reported issues related to this engine defect, yet instead of issuing a full recall, I was only offered 60% coverage, leaving me with over $5,000 in out-of-pocket costs for an issue that is clearly a widespread manufacturing defect. I purchased this vehicle for its reputation of reliability and safety, especially as the primary mode of transportation for my family of five, with no nearby relatives to rely on. Given the known defects, it is unacceptable that GMC has failed to take full responsibility. I am formally requesting that GMC cover the full cost of the engine replacement and issue a recall to prevent other consumers from experiencing the same failure.
