Same like my other 2 claims for livery vehicles vehicle started losing rpms and jerking while clients on board. Excessive fumes from exhausts started diagnostics- misfire on a cylinder cause by faulty engine lifters. They all start like that. That also caused a cam shaft damage. Repairs paid out of pocket $14,000 for new engine. Incident happened around first week of december 2023. 200,000 miles forums can tip you that there are many other similar cases with engine lifters issues from gm. Escalades and suburbans and pick up trucks i will do my best to make other limo drivers from chicago to submit same report. From my investigation problems occur between 30,000 and 200,000 miles.
