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. 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.

When I attempted to remove valve stem cover the valve stem cracked and came apart. I had to have the complete TPMS valve replaced. I then noticed that the other valve stems looked in the same condition. The Mazda dealer said that this was just aging and that the rest were O.K. I am not sure if they are. I said that the stems should not crack just by removing the cover.

Ever since I brought this car I'm having issues with my headlamps. I had replaced headlight bulbs atleast 15 times. Lamps will last roughly 3 to 6 months and then burnout. I complained many times to the dealership and they have no answer to the root cause other than simply changing the bulbs. I suspect there might be an issue in wiring. Many 2008 Mazda 3 owners are complaining similar issues on-line and websites.

At 71, xxx miles 2 out of 4 the tire pressure monitor sensor valve stems have failed. The valve stem caps were oem gray plastic caps. All parts of this system on this car are oem. The valve stems corrode below where the schrader valve seal so the tires goes flat in just a few seconds.
