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.

I was returning from las vegas on a ruff paved desert hwy in my 2005 5 speed 2 door Chevy Blazer when I notice a slight smell of electrical smoke. I turned on the dome light and notice the turning signal switch arm bouncing a lot with some smoke coming out there at the column ! I slowed from 65 to 40 with my flashers on, problem solved. Got back on a smooth free way at 65 with no smoke. The switch arm got sloppier over time but still worked for about six months. Then one day I turn right with my signal on, windshield wipers came on by themselves, & the smoke was back (much stronger ) while driving slow! I then pulled into a auto parts parking lot, shut it off, & took out the keys! to my shock the wipers, & smoke kept going! I then opened the hood, unplugged the wiper motor, & again problem solved ! then came a rainy day so I had to plug back in the wipers, things still all ok! but then I made a right turn with the turn signal on! the even stronger smoke was back plus my asthma attack (used my inhaler ) ! I thought about stopping in the strong rain but I turned on the A/C on full then got very mad ! I yanked on the plastic switch arm pulling it to the left, & it popped off in my hand! problem solved except now my windshield spray, & wiper delay don't work! I still get some smoke on ruff roads! the whole turning signal witch part cost $599.95 at Chevy plus $330 labor ! to rich for me! I took the small column dashboard panel off, put a kill switch on the wiper motor power wire just in case, & a light weight wood 6" cut off stained broom handle on the 4" metal switch arm ( drilled a 5\16 hole 4" deep)! I avoid bad roads, using turning signals, & I clean my windshield by hand often ! problem solved for now! if the air bad goes off from this problem while driving I will probably have a heart attack, & die!

My 2005 Chevy trailblazer has a bad speedometer. It failed with 20,000 miles on it. It will read 120 mile an hour sitting still, then it will read 30 mile an hour, while I am going 60. It is troubling as tickets are expensive if I receive one. On the interstate, you have no idea how fast you are going. Has never been in an accident. GM says $800 plus to fix it. Only has 39000 miles on it now. Thousands of these have the same problem. Completely unsafe. The whole assembly has to be replaced to repair to fix it.

2005 Chevrolet trailblazer 4WD 1. check engine light stays on consistently 2. when driving at night the headlights and instrument lights will dim and/or flash on and off. 3. when stopped the vehicle will suddenly rev which has happened many times and fortunately I pressed the brake in time or I would have rear ended several vehicles. 4A. the gauges on my vehicle are completely haywire. The speedometer will at times not move at all or go all the way past 120 mph, at other times it will stick on whatever speed I might be going at the moment and not move. Other times it will stick at whatever speed I was going and then proceed to move which may show I'm going 10, 20 30, .... miles faster than the actual speed I'm traveling. 4B. the oil gauge has gone all the way over and no longer moves. These are all very dangerous incidents which should be recalled
