NHTSA Complaint #11703046 — 2020 GMC YUKON XL

This concerns a 2020 GMC Yukon XL Denali motor (6.2L gas) 118,000 miles. Regular maintenance performed every 5 K miles and per request of original dealer. Beginning 2 weeks ago a new regular pinging developed and the vehicle was taken to the dealer (at which time new tires were installed routinely). No clear issues were found upon brief inspection/auscultation and advised to return if the sound was recurrent. The sound persisted on a fairly frequent though intermittent basis. A recording was made and another appt made for routine spark plug replacement. Upon return and repeat inspection it was discovered that oil filter was full of metal shavings and advised it was very likely necessary for a complete engine overhaul (with $18-20 K price tag). Checking online it was discovered that this GM motor had a 580,000 vehicle recall for 2021-2024 models. A new ODI study is being done for similar complaints for 2019-2021 year models (additional 280,000 vehicles). The 6.2L motors have been found to have a crankshaft/bearing issue leading to motor failure and even sudden loss of power often presenting with metal particulate matter being discovered. Awaiting resolution.
