Example complaints

Electrical system: “I bought my car in nov 2002, at 60,000 miles. The check engine light continually stays on. The car runs rough and has poor accerlation. We have it in the shop 4 times, and thats only for this year. We've replaced 3 o2 sensors, the air induction hose. The servicer has also cleaned the EGR valve port. The check engine light will stay off for 2 or 3 weeks and then it's on again. I'm very unsatisfied with Mazda.”

NHTSA complaint #10066557, filed 2004-04, 60,000 miles

Engine cooling: “I currently own a 1999 madza Millenia, which I purchased pre-owned, in 2002. I have had nothing but problems and extremely expensive repair bills since that time. The car breaks down/is in need of repair every 3-4 months, and it is always the same major problem with 2-5 new things needing to be repaired as well. My latest repair bill, (2) weeks ago, was to the tune of $1280. 80. The check engine came on in october 2003 and has not went off since that time. …”

NHTSA complaint #10168597, filed 2006-09, 3,300 miles

Tires: “The vehicle was purchased in march 29, 2000 with 3,636 miles on it. With less than 20k miles, the tread separated on the left front tire on friday, december 22, 2000. On february 9, 2001, I took the vehicle in to be serviced, including a tire rotation and balance, 4-wheel alignment. When I went to pick up the car, the right front tire tread had separated and the technician had placed the spare on the vehicle and advised that I needed a new tire. When I told him it was the second tire in less than a year of ownership, he said I needed to contact the manufacturer. …”

NHTSA complaint #750375, filed 2001-08

Transmission and drivetrain: “While driving on a major highway at 60 miles per hour the tcs light came on and the car completely lost power. It had to be restarted in neutral while driving in the lane of traffic causing cars behind us to switch lanes to avoid hitting us. This occurred four times in a thirty five minute drive to our destination. This is not the first incident and yes, only approximately 5 weeks ago I brought my car in for service at the dealership (joyce Mazda in new jersey ) to have this corrected and spent nine hundred dollars to have this fixed (apparantl, it was not fixed). …”
