Transmission kicks really hard making the car feel like it was hit from behind. The car is hard to control at the time this happens. I've seen numerous complaints about this. It is a serious problem,especially when our 90lb daughter is driving this vehicle. I feel that Mazda needs to take care of this issue before someone is injured or worse!.
I purchased a 2003 Mazda 6 about a month ago, and I have had the hard shifting problems and the temp gauge going up to high all the time and floating back down. I was not informed of this and other recalls of this model and I have been denied to get the problem fixed. The dealer where I bought it said they flashed it a couple times but it is not stated o n my repair receipt. I feel that I am driving a dangerous car and something needs to be done!!!! I am not going to keep driving this car and I feel I can take it back because my first payment is not due yet. Be it said that this car has been in the shop 4 times since day one! they still will not fix it and it is under warranty. This is a rip off and this model is unsafe and these models should be taken off of the market!!!.
I hadn't had the car too long and was taking off from a traffic light when the hard shift first occurred. I really thought I'd been hit from behind by another car, but this was not the case. It didn't happen too often for awhile, then it started happening more frequently so I took it in. I took it to multiple Mazda dealers, where I would leave it overnight for them to try and reproduce the problem. They always insisted that they could not so I gave up for awhile. It got worse and then I saw a TSB online about the issue. The supposed fix is to flash the computer chip. Every dealer I contacted about it said they'd charge an hour labor to do this, and my private mechanic couldn't do it as it's some magical thing only the dealers can do. Anyway I have not had it flashed yet, the car is coming up on 147k and the problem is now so bad that it's dangerous. I will have the flash done in the next couple days but I don't think it will help. I also had to have the throttle body replaced a year ago as I was nearly hit by a big rig when the car shut down in the fast lane. So many people have had this and similar really dangerous problems, this car should have been recalled years ago.
