car   Check Engine Light On problem 1
Failure Date: 09/09/2014

My vehicle has been having an issue with the throttle position sensor. As well as the pcm, usually connected as noted by my mechanic. 3 things can come from this he said. I could be having an issue with the gas pedal, the computer, or I need a new throttle body. From my understanding so far the issue causes the computer to incorrectly read, causing the check engine light as well as a few others to abruptly turn on while car is in full motion, for me this is typically at 55 mph. The car then looses the ability to properly accelerate, or decelerate. I have to quickly pull my car to the shoulder, put in park while the car seems to be lurching forward, and turn off the engine. If I do not do this quick enough the engine begins to rev high and low continuously. My rpm gauge bounces around as it is doing so. After leaving the car off for a few moments I can then restart. My check engine light will now stay on for about 50 miles and turn itself off. Once the light has gone off usually withing 15 miles my car will do it all over again. After calling my dealer, because I still owe 2 more years of payment on the car, I am told that they can fix it if I have my warranty intact. Unfortunately it has run out as of July. The part alone from the dealership is $700. Why is there no recall on this issue if so many people are having it?.

Was at a stop sign to make a left turn half way thru the car stalled and all lights came on, vehicle behind me almost ran into us. 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. One week later same thing wet to pull onto a busy street and car stalled almost causing another wreck, tried to drive it home and stopped at the grocery store, when I went to pull in the car stalled again in the middle of the street, blocking on coming traffic. Called Mazda to see how much it would cost to be fixed, the lady told me that if it was still under warranty it would be free but that expired in 2011. I have seen many of the same complaints about this, Mazda has admitted to it being a problem but has not recalled it. We have two kids and thank god nothing serious has happened with us in the car. This problem could very easily cause injury or deaths to any drivers on the road.

Failure Date: 01/16/2007

After 4 previous repairs I started my car and my check engine light once again began to flash, this time flashing rapidly. I called the dealer who told me not to drive the car because the rapid flash means the car is unsafe. I was told I had a bad coil. After a $400 repair, I proceeded to drive the car home only to have the same light flash. The dealer then told me my cataliytic converters split. Now I have a $4,600 repair job on a 2003. Please check to see if there are any other complaints on this vehicle. I have had nothing but problems with this car for the past year. Thank you.

Failure Date: 10/31/2005

I purchased my Mazda in 2003. Since the purchase everything was fine until the end of oct. 2005 my engine light came on and my car was shaking, and my rpms where malfunctioning (going up and down, then back up again). I took my car to the dealership and was informed that my car jumped time, my car had under 45k miles. They fixed it, but in the beginning of Nov. 2005, not even a month later, my car did the same thing, but this time I was told that the bolts in my engine needed to be replace. Then in the summer of 2006 I had a vacuum leak, my car would start and stop, I had that repaired at repair shop of my own chose, since my warranty was up. Now in April 2007, I was informed by a repair shop, of my own chose, that I thrown a rod in my motor.

The consumer stated the engine hesitated when she hit the gas and when she is driving, it seemed to hesitate and then goes on. She said the check engine light came on. She has had it to the dealer three times. All this has happened in the last three weeks. She said that two months ago they tried to lock it and the horn started blowing. The dealer was unable to duplicate the problem.

car   Check Engine Light On problem 6
Failure Date: 04/02/2004

I drive a 2003 Mazda 6s, which I purchased from bigger's Mazda in elgin, IL. This vehicle was purchased new from them. My area of concern involves the check engine light on my vehicle, and the performance of the vehicle when this light is on. On April 2, 2004 my check engine light appeared for the third time. When I operate my vehicle with the light on it performs erratically and unusual. The last time the light came on, I was pulling out into traffic, and my vehicle bogged down. In turn, the driver behind almost rear-ended me. While driving my vehicle yesterday, I went to pass a car on the expressway, and again my car bogged down. Every time that I take my car to the dealer, I provide them with the same complaint. I have paperwork to show that I have taken it in three times. After a recent visit to my dealer, they stated, "we have no fix for the check engine light. The light will always come back on. If you are lucky, our Mazda engineers will have a remedy by August 2004 (today is 4/6/04). The check engine light is caused by a misfire in the fourth cylinder". What an awful response from the dealer. I am concerned about the safety of my car. I am also concerned about the other drivers around my car. After three visits to my dealer, I feel lost and helpless. Please advise.

Failure Date: 10/18/2003

The "new" vehicle had 900 unexplained mile on it upon purchase. Within 4 months the check engine light came on and the vehicle kicks back when changing gears. Took to dealer in pennsylvania, was advised that needed knock sensor replaced, but they did not have part. Took the vehicle to dealer in virginia, did not look at it, although I told them what other dealership said, and told them there was a recall on it. Took to different dealership and was advised that there are 2 recalls, and they were fixed. Now the fan races minutes after the vehicle is off. Also, the vehicle seems to be lacking in power despite the engine is 220 horse power.

All dash lights come on, transmission slipping, speed odometer erratic, and loss of power. It has been in the shop for 12 more days and they can not tell me anything. My piece of crap has been in the shop for 26 days, they have damaged numerous things(spoiler has crack, paint nicks on hood and doors)all I want is my money back and I walk away!.

car   Check Engine Light On problem 11
Failure Date: 05/07/2003

The engine light and transmission light indicated a problem to me, as well as the car jerking upon acceleration. After taking the car to the dealer for service it was determined that knock sensor had malfunctioned. Since the first visit to the dealership for service regarding this problem, it has happened 5 times. I have contacted my dealer and the manufacturer and am still dealing with this issue. My dealer has made no attempt to rectify the situation other than replacing the engine sensor over and over. The car was out of commision for over a week each time. I have gone to the dealer asking for their help in contacting Mazda about a new engine and or car and they are completly uncooperative.
