NHTSA complaint #11720769

Owner complaint summary

Loud engine knocking heard after starting vehicle at grocery store, vehicle was driven 25 miles to get to store so was 'warm', check engine lite on dashboard came on during knocking, was able to drive vehicle to dealership for diagnosis (approximately 3.1 miles), dealership diagnosis after engine teardown was roller lifter failure causing damaged camshaft, instead of repairing defective parts in this engine opted for new engine replacement, cost approximately $15,000 for repairs and labor out of pocket, vehicle is 2019 Escalade, less than 110,000 miles on engine, purchased in 2022 with approximately 9000 odometer miles from cadillac dealership, professionally maintained at Cadillac dealership since purchase. GMC has a NHTSA recall (EA25007) for 6.2L V8 engines (which this vehicle particular has), for the years 2021-2024. Model years 2019-2021 with these type of engines has an active investigation (no recall yet) for the same issue of 'loss of motive power due to engine failure'. We were fortunate that the failure occurred in town at low speed driving and not on the freeway with truck traffic at 75 mph, a sudden loss of power due to engine failure would greatly have increased the risk of a crash.
