Mercedes Engines Fine, Says NHTSA: No Recalls Needed
Published Date: 1/21/2025
Notice
Summary
NHTSA has decided not to investigate a complaint about possible engine part problems in certain Mercedes-Benz vehicles, including the Metris minivan, GLC300, and C300. After checking all the info from the petitioner and Mercedes-Benz, they found no strong evidence of a safety defect. So, no recalls or fixes are needed right now, and owners can keep driving without worry.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 0 costs, 1 mixed.
No Recall for M274 Mercedes Engines
If you own a Mercedes-Benz with the M274 engine (for example a 2015 C300 manufactured before May 2, 2015), NHTSA denied defect petition DP22-002 (filed April 29, 2022) and found insufficient evidence to open an investigation. NHTSA reviewed 96 related owner complaints out of 86,112 MY2015 C300 vehicles, and found only eight mentions of "wrist pins" (three alleging reduced motive power), so no recalls or required fixes are needed right now.
Metris Vehicles Not Reviewed Here
If you own a Mercedes-Benz Metris minivan, NHTSA's technical review did not include Metris vehicles because the Metris variant of the M274 engine lacks the diamond-like carbon (DLC) coated wrist pins cited in the petition. As a result, this denial does not represent a finding about Metris vehicles.
