What 2014 Mercedes-Benz GL350 owners say
Most recent owner complaints, unedited.
Water has accumulated into the spare wheel well twice causing my ad blue module to be submerged in water, making the system faulty, which then disables the car for use. I have a vehicle that can not start and a repair bill of over 20,000 due to the water accumulation issue. There is a separate recall on other models for this exact problem. This model needs to be included as well.
As I was driving down on I-27 from amarillo to lubbock at 70 miles per hour on 6/22/2020 in pleasant weather and no vehicles either in front of me or beside me, the middle panel of the panoramic sunroof suddenly exploded with the glass shattering into pieces and some of the pieces dropping into the passenger cabin. There was no rock strike, hail, nor was I traveling through any construction zone. The ambient temperature outside was 76 f.
The lane-keeping assist only intermittently works. On occasion it will alert and take corrective action, but even on sunny days with clearly demarcated lanes, it often does nothing. In researching this issue, there are several other owners who have experienced this and have said the mercedes service has unofficially acknowledged there is a batch of VIN numbers which have faulty sensors. We purchased this car because of the safety features and mercedes needs to do something to rectify this in order to keep its customers safe.
Have a mercedes gl 350 with only 63000 miles, has made a small rattle sound when first purchased that I related to being diesel, rattle has gotten worse, took in to a mechanic who stated timing chain, I called my mercedes local dealership and service manager stated he spoke with auto technician who "laughed" when he had told him my concern for the timing chain as the tech said this doesn't happen until vehicles are very high in miles like 200000. They examined my vehicle and then stated in fact it was the timing chain and quoted me 75000. Upon further research there has been an issue with others on the internet with the gl 350 2014 specifically needing timing chain replacement when under low miles. Car rattles when started, worse when cold, confirmed timing chain by local mercedes dealership.
Power steering went out while car was parked , drove car without power steering for about 9 miles to get to safe place. After car was restarted several times steering started to work fine. Took car to dealer for check of problem but they couldn't to get it to fail again. To resolve problem mercedes is replacing the power steering unit.
