What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
It only had 60,000 miles on it and seemed like a great car. One day I was driving on the freeway approximately 65mph, when I had to brake slightly and the brake pedal felt kinda mushy and my braking was slower than normal.
Tl* the contact owns a 2005 mercedes benz g500. While driving over 40 mph, the vehicle shook violently. The vehicle was taken to an independent mechanic who diagnosed that the sbc pump malfunctioned.
I was driving on highway about 50mph when vehicle suddenly would not shift gears and would not accelerate; only the engine increased rpms. I tried to manually shift gears and number on the instrument changes but the transmission would not respond.
Engine turns off, all electrical power including power steering and brake assist shuts off - when this happens vehicle becomes very difficult to operate. To regain power, vehicle must be switched to neutral, come to a complete stop, and key needs to be cycled off and back on.
Landers toyota scion at: 10825 colonel glenn road little rock, [ZIP] sold me a 2009 mercedes benz g55 amg described in overall immaculate, excellent, mint, and showroom condition vehicle and amongst a dozen other issues and problems with misrepresentation, false and misleading advertisement, bait and switch, and fraud…
My front seats recline buttons don't work properly. They go opposite then what your doing. One day I was driving on the high way and I tried to recline the seat back and it went forward. It caused me to accelerate faster and almost hitting the car in front of me. This is a very common problem.
