When driving to and from somewhere when I come to a stop sign or a stop light my car will shake (vibrate) alot and sometimes almost die so I have to push on the gas a little or put the car in park. Also another issue I have is my car wont always turn over. I have replaced many piecxes and have taken it to Mazda dealer ships and noone can seem to find the exact problem. They say it is an intermiten problem. This can be very dangerous especially sense I have two kids that are always in the car with me.

Plague with fuel system problem. 1st time check engine came on, when car reached 44,000 miles. I took it to dealer, they ran a diagnostic, and replaced the O2 sensor. Warranty covered. 2nd time check engine came on at 51,000 miles. Dealer replaced 2 of the fuel injectors. When car reach 85,000 miles, engine started sputtering when I pressed gas pedal, engine just dies on the street. This time dealer said fuel pump might be bad. So we got it replaced for $800. When car reach 100,000 miles I had fuel line cleaned from fuel tank to the fuel injectors, and replaced spark plugs. At 105,000 miles check engine light came on again. I took car to autozone parts and had it read. The code says, P2004 (variable tumble shutter valve stuck open). The next day I was going take it to a local auto repair shop and have it looked at, but on my way the check engine light wasn't lit anymore, so I drove straight to work. 3 days after, check engine light came on again, so I just ignored it. And 2 days later, it disappeared. All these time, since I bought my car I never missed a regular maintenance, I.e., oil change, air filter change, flushed fluids. The car has gone through tire replacement, new brakes pads, new battery. Right now, the check engine light is not lit.

I developed a tick in the engine, took to dealer who diagnosed " the shutter valve inside the intake manifold was coming apart". took it to another independent Mazda repair shop and was told "the valve is actually just stuck open". both shops quoted a $1500 repair bill. This should not happen to a car that is only 5 1/2 years old. You can't just replace the plastic shutter valve, you have to replace the entire intake manifold (that part costs $1000). Since I only paid $14,000 total for the whole car, I am very upset with (my 1st and last) Mazda. I will repair and sell asap.

Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6). Hello, I own a 2005 Mazda 3. 2.3 motor. I am having a lot of difficulties with two motor mounts. The vehicle only has 60,000 miles on it and the two are already broken. After reading several reviews and after going to several auto mechanics it has been brought to my acknowledgement that many consumers are having problems with these motor mounts. The motor mounts cause intense vibration while slowing and speeding. It is pretty scary. I which they would not only call the part a defect but recall it. I feel it is not safe to drive the vehicle and all the auto mechanics tell me the same. Mazda of course states it is not a hazard. When someone's engines drops out of the vehicle due to the motor mounts failing because they are defective I ensure they will readvise their judgment. [xxx]

: the contact stated while driving 50 mph on a highway, all power failed as the vehicle was steered to the left into traffic on 4 separate occasions. The vehicle was restarted and taken to the service dealer for inspection after the first three occasions, but diagnostics failed to recreate the failure. On the 4th occasion when the power failed, the vehicle impacted the guardrail head on. Emergency medical and police responded to the accident and a police report was taken. The contact sustained minor injuries to the shoulder along with bruising to the upper body. Seatbelts were worn at the time of the accident. The vehicle was towed to the service dealer and the manufacturer was notified. Photos were taken by the contact. Updated 10/31/2006 -

The contact stated 2005 Mazda died on the highway while going approximately 5-15 mph. This is the first incident of this kind. It happened on 8-5-05. Right before vehicle died several lights came on, but she did not know wihich ones. About 15 minutes later vehicle restarted. The dealer could not duplicate the problem. She was going to take it back to the dealer to see if they could duplicate the problem.
