  ENGINE

  My 2017 G550 misfired on a highway and I had total failure with kids in the backseat creating an immediate life-safety hazard. This issue was caused by the M176 engine, which is known to create misfires. Mercedes tried to blame it on me not changing my spark plus, but I showed proof they were changed with a certified Mercedes mechanic. G wagons with that engine should 100% be recalled. They make the vehicle extremely unsafe to drive as it can happen at anytime with ZERO warning. Mercedes still has my vehicle 1 month later and it's not safe to drive.

  SERVICE BRAKES, AIR:ANTILOCK:ABS WARNING LIGHT, ELECTRONIC STABILITY CONTROL (ESC)

  Dear NHTSA Please consider this a formal complaint against Mercedes-Benz for completely defective ABS and EPS systems which control handling, dynamic stability, and anti-lock braking. The “Defective” designation is theirs, rather than a notice to service or that the systems were merely off-line or required repair. The failure notice was issued by the car itself. These critical system failures were only one of many Distonic (radar, cruise control, vehicle spacing, automatic braking), front and rear sensors, rear camera, and navigation failures. But this one is reported to you separately because of its severity, and the frequent failure of the Mercedes-Benz computer systems to even record and log failures like this. The full explanation and documentation is covered in the 3 documents attached to this complaint. [xxx] Mercedes-Benz 2017 G63 AMG VIN [xxx] PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *cc
