Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My 2002 ML320 cluster display lights on my dash all light up, the check engine light comes on, the speedometer stops working actually goes to zero. Once the car comes to a complete stop it accelerates very slowly and will not shift out of first gear. This is very frightening for someone in traffic and this happens without warning. Please investigate this issue before someone is rear ended and dies.”

NHTSA complaint #10503370, filed 2013-03, 120,000 miles

“[mercedes benz ml 320 2002] while driving east on route 80 at 65 MPH and approaching the toll booths of the george washington bridge, I tapped my brakes to disengage my speed control. The speed control did not shut down. I hit the brake pedal several more times harder and harder, but the speed control stayed in control. I pushed down very hard on the brake pedal with both feet and although the car slowed a little, the speed control dramatically speeded up the engine with the tachometer going almost full scale. …”

“To whom it may concern, I had a near death experience while driving one of your vehicles. I am the owner of a mercedes 2002 ML320, which was purchased at a phillips mercedes dealership in virginia beach va. I need to address a very serious incident that occurred over the weekend (december 18, 2010). I was driving back from richmond going toward virginia beach, I was driving 70 MPH on I-64 and had it on cruise control, ahead I saw that traffic slowing down so I stepped on the break; I then realized that my brakes weren't working and I was unable to stop or slow the car down. …”

“Was driving vehicle on highway at 75 MPH set speed in cruise control and stepped on brake as I approached traffic congestion. Vehicle would not stop and continued to maintain set speed regardless how hard I pressed on the brake. Eventually, I decided to try shifting into neutral and the vehicle was placed back under control of the footbrake. Thankfully, the vehicle was slowed down without incident but it was a very scary moment. Noticed, at this time, the bas/esp malfunction indicator lamp was displayed on the dashboard. Drove vehicle directly to a mercedes dealership for repairs. …”

NHTSA complaint #10247405, filed 2008-10, 105,003 miles

“Driving on rt 30 in camden nj when my vehicle began accelerating at high rate of speed (I was traveling at 50mph and vehicle sped up to about 80 and I could not stop it). I had to put emergency brakes and ultimately put vehicle into park to get it to stop. Nothing in vehicle caused vehicle to accelerate and vehicle did not stop and nearly caused me to drive into traffic. Mercedes denies having any problems with vehicles and blamed me for operation. I have been driving on the road as a police officer for 14 years and know that it was an issue with vehicle that caused this problem”
