Example complaints

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

“Brake pedal is too close to accelerator pedal. Whenever I operate the gas pedal, the side of my shoe also activates the brake. The problem is aggravated by the center tunnel carpet intruding on the minimal accelerator pedal space.”

NHTSA complaint #10908871, filed 2016-09, 42,000 miles

“For the past two mornings my car has no brakes when I first start my car, once I have been driving for a few minutes it's okay, but first thing the past two mornings I haven't had brakes!”

NHTSA complaint #10641123, filed 2014-10, 163,000 miles

“During a frontal drivers side crash the drivers side airbag did not deploy causing injury to the driver. However the passenger side airbag did deploy, but no passengers were present at the time of the accident. The impact of the crash was mostly drivers side. I also believe the braking system failed since my car failed to slow like a car should during braking.”

NHTSA complaint #10130085, filed 2005-07, 19,215 miles

“I am writing to officially inform you of a problem that continues to need to be replaced on my 2004 S40. I have owed the car since 2006 and am about to bring it in for the forth (4) time to have the hydraulic brake valve pump and hoses replaced. Only this time it is not under warranty because I have 65k miles on the car. So I have to pay for this unwillingly. The brakes lock and the car continues to slide. I have had one mini-fender bender due to this issue, but my insurance won't acknowledge that it was because of the car. …”

NHTSA complaint #10310851, filed 2010-02, 45,000 miles

“Consumer is experiencing on going problems with applying the brake pedal and the accelerator pedal simultaneously. The condition causes the vehicle to accelerate when applying the brakes.
