Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“As I'm driving my clutch pedal gets stuck when it hits the floor and wouldn't up back up on its own and I would have to use my foot to tap it under to go back up. Clutch pedal seems to be leaking oil also. Also at times when I'm wanting to change gears the shift knob would grind gears. If I'm going at a fast speed it often keeps me from shifting to fifth gear and I would have to jump to sixth instead.”
NHTSA complaint #10586448, filed 2014-05, 82,480 miles“My steering wheel is turning to the left on its own and it is difficult to turn to the right. I have researched online and I'm not the only one having the problem. I don't feel safe driving my vehicle and I am disappointed in the quality of parts. Issue 2: after the first recall on my vehicle, my motor is giving me issues again after being replaced 40,000 miles later. It turns off at idle and has problems starting. I fear this might be a safety issue.”
NHTSA complaint #10824047, filed 2016-02, 100,000 miles“Hello. How are you? I hope everything is going well for you. I am an owner of 2005 Mazda rx8. I was a faculty of one university at texas by 2016. However, I left USA last fall and currently settled down in korea. I also took my car (2005 Mazda rx8) from USA to korea. In terms of safety recall notices, I asked Mazda USA to solve two safety recall issues (Mazda recall #: 1017e—fuel tank leak as well as 9416e—takata recall) for my car. Unfortunately, there are no Mazda dealer shops in korea, so I asked to Mazda USA to send the parts via the mail to replace bad parts for my car. …”
NHTSA complaint #11051395, filed 2017-11, 90,000 miles“The fuel pump outlet pipe connector was leaking for sometime. It eventually caused startup problem in very hot weather. This leaked very slowly and all RX-8 should be recalled to replace the 12 flexible pipe/tubing with a reliable connector that does not leak. This connector must have been a issue, not a lot of cars used this since mid 2000. Very hard to find replacement parts. And coupled with overheated cat emissions its a fire waiting to happen.”
NHTSA complaint #10883841, filed 2016-07, 130,000 miles“Dt: the consumer purchased a new Mazda rx8. The vehicle experienced what the consumer suspected was a problem that occurred while in park and the rpms increased, causing excessive heat buildup which affected the oxygen sensors as well as the ability to drive the vehicle. This could also lead to a fuel tank leak and ultimately a fire. Vehicle would not restart and had to be towed to the Mazda dealer. The Mazda dealer notified the consumer about a recall of a similar nature concerning the fuel tank. …”
