“When I take my foot off the gas it stays at the same speed or it speeds up on its own. When I press on the break sometimes it feels like it's not going to stop and just keep going or it jerks forward when I stop. This happens when I am driving on the road and the cruise control is not on when this happens.”
NHTSA complaint #11343015, filed 2020-08, 159,185 miles“While driving home the car seemed to have lost all power, but was still running. I was able to coast to my house but then tried to stop and the car surged. I had to pull the emergency brake to stop. I was quite shaken at that point. The engine light came on. I was able to drive it back to town to have the car checked, no error codes showed up on the computer. The engine light did go off, the car ran fine for about 3 months then proceeded to do the same thing. The car lost power but I was able to coast to my place of work. …”
NHTSA complaint #10557598, filed 2013-12, 155,000 miles“I was driving on the interstate in ga going a little over 70mph in the fast lane and all of a sudden it kicked in to limp mode to about 10mph. I almost had a semi rear end me but was lucky enough to get out of the way just in time. I could turn the car off and it would reset it for awhile and then do it again. Then it finally got to the point it was doing it way too much. It turned out to be the throttle body. I learned that they know about it but wont recall it. Its been sitting for a year because they want $900.00 to fix it. …”
NHTSA complaint #10552526, filed 2013-11, 110,000 miles“I purchased my 2003 Mazda 6s in october 2003. Since I have owned the car I gets poor gas mileage on it (about 16-18 miles per gallon). I do plenty of city driving but I still feel that this is not adequate. Even when I drive on the highway the gas mileage averages poorly. There is also a smell coming from the exhaust when vehicle is in motion. The vehicle also rev's up higher before switching from lower gears to higher gears. I do not 'jack rabbit' start or stop the vehicle. There is also alot of brake dust on the rims of the front wheels. Acceleration is very poor. …”

Barely got pulled over to the side of the road had to turn car off and then back on the check engine light remained on but vehicle would drive, after about 5 starts the light came off had the car checked, was told it was the throttle body. …”
