I am the original owner of the vehicle, I complained of engine surge on several visits to Mazda, and they would always say they were unable to duplicate the problem. I was recently driving the vehicle when it accelerated on it's own, the RPM's would fluctuate between 2 and 4. the vehicle accelerated uncontrollably, I had difficulty stopping at stop signs and traffic lights on my way to my mechanic. When I reached his garage I left the vehicle in park to show him what it was doing and it idled at 3 rpms. The mechanic has not been able to repair the vehicle. I have researched the problem and have found that other Mazda and Ford vehicles have had similar issues.

Engine will shut off without warning at any speed. I researched the issue and found that there are a large number of complaints regarding the exact same symptoms with the 2003-2005 Mazda 6. Mazda even released a service bulletin: 01-016/06 in 2006 regarding a bad throttle body with aa, ab, or ba markings. Sure enough after removing the throttle body, mine had the aa markings. From the amount of online complaints and the fact that a service bulletin was released, this is not an isolated issue. This is a huge safety concern and should be a safety recall. To top it off, currently Mazda has an issue with replacement throttle body's that will cause the car to jerk and stall at anytime. They have admitted that the current new stock of throttle bodies will not work with my vehicle. This will cause people to keep driving with a bad throttle body since there is no replacement.

2004 Mazda 6 wagon. During the 6 months I have owned this vehicle. I have had four occurrences when taking a highway ramp that the car either stalls or looses power when re-entering the roadway. This occurs when the fuel tank is a 1/4 full and below.

Engine failed while driving because of a problem with the throttle body. There was no warning. Found that Mazda has known about this problem since May 2006 in fact there is a service bulletin that completely identifies this situation down to the part number code on the defective part. Bulletin number 01-016/06. This happened on a major freeway at 70 mph, it was just luck that I was able to get off of the highway without a major incident. My car was under warranty when this bulletin came out why was it not replaced or recalled.. I have seen recalls for many things with less safety impact. I was charge $473 for the repair.
