GL450 8-cyl

  • 5,000 miles


My 2007 Mercedes Benz GL450 has a problem since about 5,000 miles. The brake pedal has too much travel to stop especially, in traffic the pedal goes all most to the floor it is extremely dangerous. I have repeatedly brought it to the dealers attention. Even after they performed a complete brake job. There reply was it is normal they all do the same.

2007 Mercedes Benz GL450, did all scheduled maintenance at dealer, only 36000 miles, the 'brake wear' message just came up on the console. Dealer checked and said all brake pads, front brake rotors need to be replaced. So only 36K miles and well maintained vehicle, when the brake sensor just indicated 'brake wear' problem, not only all pads are bad, but also the rotors were damaged already? it seems to be defect of brake system, including the brake sensor.

Today my husband was involved in a car accident while driving my 2007 GL450. Thank god he wasn't injured but the situation he explained to me has happened several times before and I've been able to regain control of the car before something terrible happened. He left home for work at about 6am and while still in the subdivision driving about 20 miles/hr on a road with about 1" of snow, he tried to make a right turn but the brakes locked and the steering wouldn't turn and he ended up smashing the front end on a huge stone and ricocheting to a fire hydrant. Like I said, this has happened before and I'd been assuming that the skidding was because our tires were worn but we got brand new tires less than a week ago so this does not make any sense. I haven't been in touch with Mercedes yet but I will be contacting them to advise them of this issue.

1. made a left turn onto the roadway from a stop. 2. had failure of the ABS, esp and parktronic systems of the vehicle. Steering wheel felt like there was a loss of power steering. 3. the vehicle was parked and started. This condition self corrected after starting the vehicle a second time. Have heard this is an issue with vehicles from other manufacturers as well.

  • Automatic transmission
  • 4,000 miles
The contact owns a 2007 Mercedes Benz GL450. The contact heard a squeaking noise when he depressed the brake pedal and the stopping distance increased. The dealer was unable to diagnose the cause of failure, however, they grinded the edges of the brake pads to reduce the squeaking noise. The speed was unknown. The failure mileage was 4,000 and current mileage was 6,600. The dealer recommended chamfering the brake pads to alleviate the noise. The dealer stated vehicle low on oil. Updated 09/2807
