Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

A D V E R T I S E M E N T S

Incident 2005 Mazda 6 broke down along side road. Engine only had 40,000 miles on it. Called Mazda service manager, bob, and he told me to have it towed there and he'd take care of me. I was later told the engine blew but as his crew looked at it they verified that the engine and oil was clean. He said he'd call regional and see what he could do for me to get the engine repaired/replaced. Damage resulting after several weeks of run around I was finally told it was going to cost $90 for the service team to have looked at the engine. I was then informed that he could put a salvaged engine in for $4000. I about freaked out. $4000 for a used engine that came with a mere 90 day warranty. I called Mazda headquarters and was told I should've bought an extended warranty. I told her she was crazy that no car costing over $20,000 should blowing engines with a mere 40,000. I then asked if Mazda would help out by paying for service or the engine or at least half so that I could get the car back working. She told me that bob offered me a great deal and I had refused him. I told her what he offered and $4000 for a used engine plus other parts as needed didn't sound like a good deal to me at all. I asked her if it was her car if she would not expect Mazda to stand behind their product and assist? she told me that Mazda stands behind their products and I should've purchased the extended warranty. After reviewing the internet I see Mazda 6 engines seem to have alot of loss of oil/blow out problems. Always thought Mazda was a good company...but I know I'll never purchase another and I'll make sure everyone I speak with hears first hand of my experience with the vehicle, the dealers run around and the arrogance at Mazda hq in California.

I think the Mazda line of vehicles should be looked into. I have a 2005 Mazda 6 I sedan that from the very beginning had issues. At 5000 miles I complained to the NHTSA because the car shut off on me on the highway. I took it to the dealership and the dealership could not duplicate the problem. The problem with the car shutting off has happened a few other times over the years and I've always had it investigated however the dealership could never find an issue. Finally it is 2011 and the car has 96000 miles on it and is completely shut down. As it turns out despite getting every piece of maintenance done on time and in order by the manufacturer cylinder #2 and #3 misfire and ultimately need "rethreading?". I wonder if this was a problem on the car to begin with. I have talked to a few other Mazda 6 owners who have had a similar experience as I did.

MAZDA6 6-cyl

  • Automatic transmission
  • 57,000 miles
The contact owns a 2005 Mazda6. The contact stated that while at a traffic light, the vehicle began to hesitate as if it were going to stall. The contact had to apply pressure to the accelerator pedal in order to keep the engine running. The contact took the vehicle to the dealer and was told that two engine coils needed to be replaced; however, when that did not correct the failure, the contact was told that the catalytic converter needed to be replaced. The failure continued to occur and the contact was told that the engine needed to be replaced. The contact was concerned that the failure was a manufacturers defect that was never repaired under warranty. The failure mileage was 57,000 and the current mileage was 66,000.

  • 122,500 miles
We were driving from los angeles, ca to fremont, ca on the I-5 highway. Weather was hot - about 95F to 100F that day. About mid-way in our drive, the car became very jerky when I lift off, or step back on, the throttle. I pulled off to the closest exit and proceeded to a gas station. As we were rolling to the gas station, I needed to step extremely hard on the brake pedal, but was still not able to completely stop the vehicle. Vehicle kept rolling at ~5 mph despite I step hard on the brake. I needed to push the transmission lever to neutral, and then pulled the hand-brake to completely stop the vehicle. After the car was stopped, the engine RPM hovered between 2K - 3K RPM, but my foot was off the gas pedal already. The check-engine-light was not on, and the car was not overheating. We opened the hood and checked the fluids, and everything was normal. We felt we were not able to stop the car because of the engine hovered at 2-3K RPM despite my foot being completely off the gas pedal. We then shut down the car. After 10 minutes, we re-started the car and everything was normal again. It has been ~500 miles since this incident but the issue has not returned yet. Nonetheless, we feel that it is a dangerous safety issue because when it happened, the car cannot be safely stopped.

MAZDA6 4-cyl

  • Automatic transmission
  • 3,000 miles
In August of 2005 I purchased a Mazda 6 (automatic transmission). After 2 - 3 weeks of ownership my Mazda died on me one day while driving on the highway. I immediately took it to the dealership yet no problem was identified. 4 - 5 months later my car stalled while sitting at a light. A couple of months after that, my Mazda stalled again. A couple of days ago while backing out of the driveway my car just turned off. It's so annoying because I always take it to the dealership immediately after the stalling occurs and they can never identify a problem; they try to recreate the conditions and put miles on my car but it doesn't stall for them. When it stalls there is no warning (I.e no lights, engine noise, etc). It turns right back on immediately; I notice the lights and the fact that my engine is no longer on. I simply put the car in park and turn the ignition and the car runs fine. This stalling occurs every 5 - 7 months. I've complained and complained to every Mazda dealership I've been to and have sent multiple emails and made multiple phone calls to the corporate office about this issue. Because the problem can't be identified the Mazda technicians can offer no remedy.
