NHTSA Complaint #11542485 — 2012 MERCEDES-BENZ GL350

Mercedes Benz settled with U.S Government the diesel emission scandal. There are about 122k class members. Under the settlement, Mercedes gave 122k class members 4 year/48k miles warranty. Under the warranty, MB replaced the timing chain in May 2022 but on April, 2023 while driving on I-95 in Massachusetts, the engine completely got shut down while driving 55 miles per hour. Luckily, no one got injured. But the car was not controllable. I barely pulled to the side of the hwy and called the towing. Brought it to MB of Westwood. MB Westwood did a diagnostics.Below is the note Mercedes Benz of Westwood: The car is still at the dealership if you want to send an investigator, Engine Rebuild/Replace: after further tear down found that timing chain guide rails broke, which then got chewed up from chain and gears into smaller pieces. these small pieces got suck up into the oil pump pick up tube, blocking oil flow. The lack of oil to main engine components caused them to overheat and contacted each other (metal to metal). which ends up heating to a point in which the components stick to each other and not able to move freely any more.. Basically, The replaced Timing Chain destroyed plastic guide rails, which destroyed my engine. I notified Mercedes Benz of USA and the dealership that they need to recall 122k class members and fix the problem, but they refused to take any actions. By ignoring the problem, it could lead to casualties to thousand of people. I hope you take actions and bring Mercedes Benz USA accountable and they start recalling and fixing the problem before its too late.
