Example complaints

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

“I purchased a new Kia Optima in 2004. In 2005 the rear passenger tire smelled like burnt rubber. I took the car into dorschel automotive group. They stated that the brakes needed grease and I was all set. The rear brake continued to smell like smoke intermittently and shrugged it off due to lubricants. In 2007 I complained of the problem of smell of smoke and a sound of medal on medal everytime I made a turn. Dorschel inspected the brakes and stated I needed new rotors and new brake pads in the rear. The car only had 14,230 miles on it. …”

NHTSA complaint #10475630, filed 2012-09, 700 miles

“I recently purchased a Kia Optima 2004, on december 28,2005 I notice a piercing noise coming from the back of my car. I took the car into the local dealership who indicated that I needed new brake pads and that my rotors were rusted. My question is how can a car that is brand new and only driven for 14 months have rusted rotors. Isn't there safety standards on material used so that this does not occur in such short of a time. It was not covered under warranty which resulted in a bill totaling $659.00. My purpose of purchasing a new car was to avoid constant repairs right away. …”

“The contact owns a 2004 Kia Optima. While driving at an unknown speed, the contact heard a grinding noise coming from the rear passenger side tire. The vehicle was taken to the shop the following day for an oil change, and it was discovered that the rear passenger caliper was frozen and would not release. The rotor and caliper were replaced. Approximately 8,000 miles later, the pads and rotors had to be replaced again. There is no recall regarding this failure. The current mileage was 17,080 and failure mileage was 80,000.”
