Open the full vehicle complaint log (all categories)While passing a vehicle on a two lane road, my vehicle lost power and went into limp mode nearly causing a head on accident. The check engine light came on and i immediately went to O'Reilly's Auto parts store and had their OBD scanner read the code. AP0002 code was read. I immediately returned home and the check engine light automatically cleared. I scanned the OBD again and found code P0002 and a second code P000277 that was listed as stored and current Both codes refer to an issue with the high pressure fuel pump. I just recently purchased this vehicle with 35170 miles. I had the OBD scanned prior to purchase, there were no codes at that time so we purchased the vehicle. We've since put 1000 miles on the vehicle and without any warning, this issue suddenly happened. I have done some research and Mercedes offered an extended 120000 mile/10 year warranty that addressed this exact issue, however, that warranty is now up due to the age of the vehicle. This issue put us and others at server risk of a major accident do to this issue happening with no warning. I haven't tried to reproduce the scenario that occurred, however the codes remain on the OBD computer.
SIGNIFICANT TIMING CHAIN RATTLE WHILE DRIVING IN THE 2200-2900 RPM RANGE. ENGINE HAS LESS THAN 70K MILES AND IT SEEMS THAT THE CHAIN HAS STRETCHED OR IS TENSIONER IS FAILING. MERCEDES CLAIMS THEY CANNOT FIND SOURCE OF RATTLE AND REFUSES TO FIX IT, BUT ONLINE FORUMS INDICATE THIS IS A KNOWN ISSUE FOR THIS ENGINE. I FEEL THEY ARE DEFERRING THE ISSUE UNTIL THE WARRANTY EXPIRES. I FEEL EARLY FAILURE OF THE TIMING CHAIN OR RELATED PARTS IS IMMINENT.
