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.

Several times since I got my car, it has stopped running while I was driving. I had the mass air flow sensor replaced, the fuel pump, the BCM also but it still continues to shut off completely while I'm on the road. My check engine light was not on the last time it did it and I've done several repairs to attempt to fix it. Ive spent nearly 1000 in these repairs and still nothing works. I'm afraid to drive my car but I have to work. I take care of my vehicles and I'm not sure if this is a GM issue or what, but I've read many complaints sounding similar to mine and I want something done. I was on a very busy road on these days and in complete motion (35 mph and above)

Issues with system security system and intermittent starting issues as noted in the hundreds of previously reports. Is this just a waste of time, providing this information to NHTSA" or is someone going to step up to the plate and have GM fix this problem"

Impala 6-cyl

  • 40,000 miles
My passlock system has been malfunctioning for years now (2007-2015) and at random intervals, my car will not start and I have to wait 15 minutes before the engine will start. Sometimes the "security" light will turn on while I am operating the vehicle and after I have parked it, the security light will flash and I can't start the engine until after the 15 minute cycle has concluded. Not only has this issue been an inconvenience, but I have had occasions where it has put me in danger. I am not responsible for the passlock system failure, nor do I have the funds to repair or remove it. I believe that passlock was a faulty system from the beginning and the fact that it has not been recalled shocks me. I am very afraid that one day the passlock system malfunction will occur when the vehicle is in motion and that I will lose power steering, braking, and other vital operational functions. Noticeably, the passlock malfunction has become more frequent, so I needed to file this complaint. I have talked to service experts at my local Chevy dealership and they have told me on more than one occasion that this issue is widespread, including many GM vehicles, and that eventually my car just won't start anymore. The quoted prices to fix this issue (either repairing it or removing it entirely) have been ridiculously high and I don't understand why I should be forced into paying for a well-known GM/Chevrolet problem.

Impala 6-cyl

  • miles
2003 Chevrolet Impala. Consumer writes in regards to vehicle starting problems and electrical system/ ignition recall notice. The consumer stated the starting problems began two years into owning the vehicle. Every mechanic charged him hundreds of dollars in parts and labor, only for the problem to return. In September 2014, the consumer received a recall notice. He took the vehicle to the dealer, where they put two rings on his key fob. They also informed him the ignition switch and sensor needed to be replaced, which cost him several hundred dollars. The consumer stated the starting problem has ceased. The consumer believed his problem qualified to be recalled, since several other vehicles were being recalled for ignition problems. Also, the left front door latch assembly was replaced.

My vehicle will lock me out from starting it, and will display security. I believe this same issue is affecting my traction control. This is a known issue and I know several people who have dealt with this same issue. It is absolutely nonsense that this issue has not been addressed.

I have not had an accident. I have had this car little over a year and had nothing but problems with it. Started off security light flashing then not starting I could unhook battery and reset and it would start. Lights would flash interior lights stayed on then didn't work voltage meter would bury to 0 but battery was fine air consign will not work when this happens door locks do then don't work blows fuses trunk will poc open radio will lock headlights flash T I ll I put manual lights on then automatic would work later. Security light flashes a lot of the time all these things start acting up and it continues to get worse. Sometime car will jerk and I have to reset by taking cable off then it works fine. I have kids and I do not feel very safe B in this car. Some of hard working single parents can't afford to spend 700 here and there from trial and error when it seems a lot of models from this year have the issue.
