Consumer Description

On 05.29.25 my 2021 GMC Yukon Denali with 24,000 experienced engine issues and ultimately a total failure. While driving at 65 miles an hour the engine light began blinking and a thumping/knocking noise began on the front passenger side of the vehicle. I was 1 mile away from the GM dealership and went there immediately. They called me two hours later confirming the engine failure and that it would have to be replaced. They stated, however, the engine is experiencing a national backorder. No timeline has been provided for the engine to be received or replaced. I am curious to know if the new engine will come from the same engine group that is currently having issues, and if this can happen again.
