Kehoe Law Firm, P.C. is investigating consumer claims on behalf of owners and lessees of Mercedes vehicles equipped with an M274 engine.
The investigation concerns an alleged defect regarding the pistons of the M274 engine which are prone to premature failure – an issue that may require the costly replacement of the entire engine.
The Office of Defects Investigation (“ODI”) received a petition dated April 29, 2022 requesting investigation of engine piston damage attributed to improperly sized wrist pins in the M274 engine found in the owner’s 2015 C300.
The petitioner reported that their MY 2015 Mercedes C300 vehicle lost power while driving at highway speeds accompanied by shaking, white smoke from the exhaust, and a burnt oil smell. Subsequent diagnosis at the dealership identified a cracked piston.
The petition alleges that all Mercedes-Benz models equipped with a variation of the M274 engine should be included in the evaluation and cites Mercedes TSB LI03.10-P-060916.
