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: The Toyota Matrix is the mechanical twin of the Pontiac Vibe.

Both models were a joint GM-Toyota venture, manufactured together at a NUMMI production facility in Fremont, CA. Only the heating & A/C systems are different.

Today on my way to work the car started making a ticking noise, that turned to rattle when I hit the gas. After a few miles, the noise became louder, as I was on a major highway. I made my way off to a side road and the engine died. Dead! Waiting for the tow truck, I noticed that oil leaked from under the engine. There were no leaks of any fluids before that.

I had the car towed to Canadian Tire -a couple of miles from where it died-and they pronounced it to have a hole in the engine, has the car is now a second car and my son mainly drives it, we decided to scrap it, not worth fixing for 3 to 4 thousand dollars. I was very surprised to find so many complaints about this model of car. Very disappointed, I thought we would get more time with it, has it was bought new and maintained, with no major problems, other than normal car maintenance.

Well... bought this car certified from a toyota dealership. Bought the extended warranty they pitched to me (also with the maintenance plan). Had car oil changes/ maintenance done every due date. Bought car around 42k miles, failed around 60k. I drove 800 miles to Michigan, on the way back I heard cylinders hitting. I pulled over, oil showed almost empty. I put in some quarts, drove home. The next day it was practically empty again so I filled it up more and took it to the dealer. The warranty covered the issue, though the dealership said it was a probably from a bad valve. Thank god I had the warranty, but this is ridiculous ...60k miles...really?!?
