What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Tl* the contact owned a 2010 mercedes benz gl350. The contact stated they were involved in a front end collision while driving at approximately 55 mph. The vehicle air bags deployed as a result the contact sustained bruising to both arms, moderate to severe pain and a broken right foot that required medical attention.
This vehicle which is the x164 chassis has a rear fixed panoramic sunroof that is made out of polycarbonate. The polycarbonate sunroof glass is breaking down on the inside of the panel and is cracking. This poses a safety concern due to the fact that once it cracks and degrades to a certain point it will break.
Tl* takata recall. The contact owns a 2010 mercedes-benz gl350. The contact received notification of nhtsa campaign number: 16v081000 (air bags). The part to do the recall repair was unavailable. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair.
Takata recall very concerning that my car is included in the airbag recall yet the airbag mfr has filed for chapter 11. I want this resolved and corrected so I can feel safe driving my car!
The "check engine light" is on, when I took the car to the dealer, they told, " the ad blue tank is corroded." I have alway fueled with disel recommended by mercedes. How can tank get corroded so early. I suspect faulty in the manufacturing. I request you to do necessary investigation into it.
Few days after, check engine light came on, and I took the gl350 in for a check, and another mechanic confirmed that the engine oil cooler seal is broken causing the oil leak. It seems that this is a very common fault with mercedes om642 engine in my gl350.
While driving approximately 50 mph, the vehicle experienced a complete loss of power. The failure occurred twelve times prior to this incident. After each failure, the vehicle was taken to the dealer where it was diagnosed that the abs sensor malfunctioned and needed to be replaced.
After extensive reviews of tdi forums, common rail forums, diesel forums I have found a commonality in the failures in the high pressure fuel pump (hpfp). Mainly those failures were attributed to metal shavings/particles/rust found in diesel fuel systems.
