Selected complaints filed with NHTSA by 2008 Mazda Mazdaspeed3 owners, lightly cleaned up (personal details are redacted by NHTSA).
I was driving on a city road doing 35-40mph in 4th gear. I let off the gas while in 4th and coasted to about 20mph then shifted to n and stopped at a red light. When the light turned green I tried to shift to 1st an the shifter went half way in between r and 1st, so I shifted back to n and tried 1st again. Then the whole shifter broke off and was just laying there. Now my car is stuck in 3rd gear.
While shifting from 2nd to 3rd gear at low speed, the shifter for my manual transmission broke off in my hand. After coasting to the side of the road and removing the console, I discovered it snapped in half at the location of the retention pin.
A motor mount broke on my 2008 Mazdaspeed3 causing the need for replacement on the following parts: transmission two motor mounts bypass valve vehicle wiring harness drivers side axle my dealership took pictures and sent them to Mazda. Mazda says the vehicle was over driven and this is why the mount failed. They will not warranty the damages and repairs. The vehicle is less than three months old. The day after the vehicle was purchased there was a noise coming from the vehicle that was abnormal. There was an appointment scheduled with the dealership to have this looked at. The motor mount failed before this appointment. This could be related to the failure. I don't feel that pictures can determine that it was not a defect. Also, people drove the car before I did and that could cause the belief of being over driven. Test drives with customers would be what I'm referring to. …
I went to shift into first gear from a stop (at a red light,) and my shifter fell off in my hand. Upon disassembling the center console at the light, I found that the cast-aluminum shifter arm had broken at the insertion point for the retention pin. Not only am I not the only one with this issue, but it happened to another person today (whom I'm forwarding to this site.) Mazda said it's not under the powertrain warranty and because I have an aftermarket transmission mount and a cold-air intake, they won't make a goodwill adjustment (in spite of the fact that neither of those things would break it....) they have no concern over the clear safety issue, refuse to discuss other incidents and spoke to me as if this is the first car I've owned and my time would be better spent coloring on the bus.
As I was driving on the freeway, I heard a loud pop and then a flopping noise. I pulled over to the shoulder and noticed there was oil leaking from the undercarriage and white smoke. After having the vehicle towed to the dealer, it was determined that the transmission was destroyed. After the transmission was removed, the repair technician showed me the transmission, which was literally breaking in pieces. He said that I would also need a new clutch assembly and flywheel. I don't understand how this could have happened. I do not abuse the car and maintain it well. I wasn't even shifting gears at the time of the incident. Just driving along in 6th gear. Unfortunately, this happened less than a month after the warranty expired (of course) and Mazda would not help cover any costs for the repairs.
Driving normally - my vehicle is stock, never raced or abused, and only dealer-serviced. With no warning whatsoever, while driving normally in traffic, the gear shift lever broke off! I was unable to change gears at all afterwards. Only through skill and luck was I able to get the vehicle off the road without incident. The manufacturer and dealer are replacing the affected parts. However, they are using the exact same parts as before (design, part #s are identical). As other owners of this vehicle have had this same problem, this is a serious quality defect, remaining unaddressed, with safety implications.
The shift lever broke off during a shift while driving, making it impossible to shift gears after this occurred. The fault seems to lie in the design. There is a hole in the lever to accommodate a pin which prevents accidental shifting in reverse. However the hole in the lever is a weak point and it is easy to see how the lever sheared off at that point. This problem has been reported by other drivers via online message boards. Currently there is no recall. This failure is extremely dangerous and I was lucky enough to be able to pull off the road. However, this could have easily resulted in a collision.
My complaint is regarding my 2008 Mazdaspeed3 which has smoked for about a year now whenever the vehicle is stopped at red lights. This is consistent and makes breathing difficult while waiting at stop lights since the smoke gets into the cabin during most brief stops. The issue is documented under Mazda TSB 0100410 jan 10. The issue should be covered under the factory warranty; however it has not been fixed since the dealer claims they are unable to replicate the problem. I find that hard to believe since it was smoking at the dealership as I drove away from the service department.
Tl* the contact owns a 2008 Mazda, Mazdaspeed3. The contact stated that while attempting to shift into reverse, the gear lever became fractured. The vehicle was coasted to a safe location where a temporary repair was performed by the contact. The vehicle was then taken to an independent mechanic, who stated that the gear shift assembly would need to be replaced. The part was ordered for the repair. The manufacturer was not made aware of the defect. The approximate failure mileage was 85,000. The VIN was unavailable.
While shifting from 2nd to 3rd gear my shift stalk fell off in my hands. I had to turn my emergency blinkers on and pull over without being able to shift gears. I was able to reach below the shift boot and feel the shifting base mechanism to move the car back in to gear once off of the road. I am currently unable to drive the car as the shift control will not stay in place.
