general problems of the 2003 Mazda MAZDA6

The contact owns a 2003 Mazda Mazda6. The contact stated that while driving at approximately 35 mph, the vehicle suddenly shut off. The failure had occurred on multiple occasions. The cause of the failure was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 167,000.

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?.

Traveling at speeds of 30-60 mph during any type of traffic (stop and go, freeway speeds, etc), my 2003 Mazda6 will suddenly go into a "safe or limp" mode characterized by abrupt loss of power with no ability to accelerate. The rpms drop to between 1000 and 1300 and fluctuate quickly between the two numbers. I have had to quickly press the clutch, turn the car off and back on to regain normal function. When taken to a mechanic, the root cause was determined to be a defective throttle body. Upon more research (including this site), this does not appear to be an uncommon issue for this model of Mazda.

On several models of Mazda 6's Mazda has issued a TSB for the problem which is a defective throttle position sensor. I have read thousands of complaints by consumers. Mazda has made a new part yet not recalled the old part. When this part fails you lose all acceleration power to the vehicle. The way to reset this is to turn off the motor and turn it right back on. I was driving on a two-lane highway crossed over the broken double yellow line to pass another vehicle when this defective part failed and I lost all acceleration. Thankfully, I had just enough time to be able to allow the same car I was passing to pass me and I pulled off the roadway. The car worked fine for the rest of that trip it occurred again on the freeway in the fast lane. I contacted Mazda corporate customer care they advised me that they were aware of the issue but had not issued a recall at this time.

After having my 2003 Mazda 6 for no more than a week, I noticed my air conditioner was not blowing out cold air. Also, the air conditioner light shut off on any setting higher than "1". I took my vehicle into my dealer for service. I was told they would have to order a new switchboard for my dash. I waited a week for the part to come in. I was told the part may or may not be in within the next week. I became frustrated and picked up my car and asked the dealer to call me when the part came in. I waited for almost 2 months then received a letter in the mail stating my part had arrived. As I am part of the working class, I did not have a chance to respond back to the letter. I received another letter stating that if I did not make an appointment to have the part installed within 10 days, the dealer was required to send the part back to the manufacturer. I made my appointment. I was given yet another rental car. After replacing the part I waited so long to come in, I was informed that part did not fix the problem. I had to wait for another part to arrive. I was also informed that there were 3 recalls that consumers had not been informed of yet that the dealer was going to make an inspection of my vehicle to ensure the recalls were fixed. Now, right before the new years holidays, I received a call from the dealer that they have to order a new gas tank for my vehicle and the part will be ordered and should arrive "within the next couple of days". I have been promised my vehicle next week. I am not holding my breathe.

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.

I purchased a 2003 Mazda6 on 4/18/2003, at of today it has 3,800 miles. After driving about 10 miles I stopped to order food from a drive thru window. I was told that it would be 10 mins for my order to be ready, so I pulled over to a stall and waited for 15 mins, with the car still on(no ac windows down). While placing my order I heard the fan turn on I knew it was on because it was making a very loud noise (not like normal). It stay on while I was parked waiting for my order and on the drive home 10 min. It continued to stay on 90 sec after car was turned off. I went to check on the internet to see if there was a problem with anyone else and from CA to fa and even in can Mazda6 owners have had to replace relay control module. I called dealer they said that this was normal, but I could bring it in to check. After car was inspected I was told that the relay control module needed to be replaced.

Manufacturing problems with 2003 Mazda 6 / auto alliance International facility. There was rust on the door sashes of all four. The consumer's vehicle may be one of 46k assembled at the aai facility throughout July of 2003 that was potentially affected. The cd player/changer had become defective, there was a defective fuse access cover, there was a rattling in interior driver and passenger door panel while driving or when listening to music, and there was a rotten egg smell that had come from the exhaust which entered the cabin.
