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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CarComplaints.com Notes: Except for a minor issue with cracked motor mounts, the 2008 MAZDA3 is a fantastic vehicle with a great reputation.

If you need to replace the motor mounts, first ask your dealer if they'll cover it -- the motor mounts were dealt with in a TSB & were recalled for some model years. Otherwise buy aftermarket motor mounts -- owners report this solves the problem. If you use the same OEM parts, they may just crack again.

Car accident going around 60mph on a highway, hit guardrail head on due to black ice and rain, spinning twice hitting guardrails again front and back multiple times, not a single airbag deployed. Thank goodness for the seatbelt as I'm sure death would have occurred if that failed too. Going through the insurance process now and will have more pictures and police report in hand shortly. I thought my wife and kids were in a safe car... I guess not.

Car was vibrating a lot when in gear and holding brakes replaced motor mounts and throttle body to fix issue. Also when slowing down and speeding back up the transmission grinds when down shifting. Feels like it is slipping and is not safe if you are driving on the highway or in the city and want to switch lanes and speed up I'm afraid one day I'm going to switch lanes hit the gas and the transmission will fail. The carmax I got the car from insists it is just a transmission "shutter" and it happens with certain cars. I will be getting a second opinion from an ase certified transmission shop. Dealership made me think it was brake pads at first I paid $300 to have perfectly good pads replaced with new ones to have the problem not fixed. I am extremely irritated with dealership trying to get around fixing the car. Other than those 2 problems the car is great.

The right font engine mount has broke. This was a recall on the 2006 model Mazda 3 but it appears that Mazda has continued to use the recalled pat O late models of various models.

Check engine light came on 12/13/14, car wouldn't start 12/14/14, had towed to repair shop 12/15/14 and was told engine was flooded because the car couldn't meter air correctly and over fueled the car. Spark plugs, air filter and throttle body were all gummed up and dirty due to this. Repair shop checked the technical service bulletin relating to the check engine light and found that this is a a known issue. They had to modify a bracket and splice in new wire where it was rubbed through because of this defect. If this is truly a common defect Mazda should issue a recall on it and reimburse owners who have already had to have it fixed.

Complete engine failure on well maintained Mazda 3I at 75000 miles. Traveling on freeway in slowest lane of traffic, first heard a clicking noise and engine light went on. Car seemed to be losing power. Called aaa roadside help, who checked the car and determined it was ok and could be driven home, about 10 miles away. Proceeded to drive home, 5 miles into trip began losing power, clicking noise returned so I pulled over to shoulder as car completely lost power, engine overheated. Prognosis: Timing chain broke, engine overheated and this car is a total loss. Finding now there are thousands of consumers that have experienced this issue with Mazda engines. This company is a fraud, and people's lives are in danger as the result. Never again will I have anything to do with Mazda cars.

I parked my car on numerous occasions in the last few months where the transmission failed to engage in park. It required multiple tries to get the park indicator light on the dash to reflect that the car was safely engaged in park. Before I realized what was happening with the transmission. On at least 3 occasions I was unable to start my car at all when I returned from a brief stop. The problem with failing to start happened when the car was on a slight incline and I had engaged the parking brake. After jiggling the automatic transmission lever repeatedly, moving the steering wheel and applying the brake vigorously, I was eventually able to get the car to start. I'm not sure whether it was rocking of the vehicle from frustration or jiggling the gear selector that finally worked. The car has a new battery and has had all scheduled maintenance performed by my local Mazda dealer. When this happens, other electrical equipment functions but there is absolutely no response from the ignition system.

Overflow bottle cracked for no apparent reason causing problems with the engine costing more than 1500 worth of damages. The mechanic encourage that I report because he says this should not have happened and that Mazda is known for having this defect. It is a costly repair.
