I am currently receiving a shift to park message displayed while my vehicle has been put in park and after I turn the vehicle off. While the message is displayed, the doors will not lock and a bell will not stop dinging, notifying me of the error. I have to start the vehicle, shift into gear, shift into park, and turn off several times before the error disappears. I have an appointment to have the dealer look at it this week.

Shift to park will not disengage even though the car is in park. The alert will not stop sounding. Additionally, the radio and car will remain on and doors will not lock.

I went out to start my car and the light said that it was not reading the key fob because of low battery. I went and got the other key fob which had never been used and had the same result. The car was towed by Chevrolet to the dealer and it has been there for over 3 weeks. They found that it wasn't a faulty key fob but it was the receiver that gets the signal and allows the door locks to open and the engine to start. I tried moving the shift lever, stepping on the brakes, trying the remote start on the key fob and nothing would start the car nor would it lock/unlock the doors. It just kept giving me the notice that it couldn't read the key fob. I called ONSTAR and tried the actions they told me but that did not work either and they said to contact my selling dealer. ONSTAR contacted the Chevy warranty number for a tow truck but at 9PM it was too late for them to make a service call. What if I was out in a parking lot or in a remote area and experienced the same problem with no assistance. I have been trying to find out what the dealer is doing to repair my vehicle but I have to call the GM complaint line in order for them to try and contact the dealer about my car. They finally gave me a rental vehicle since the vehicle is less than 1 year old and only has about 6,000 miles on it.

The driver side door striker and door latch are defective. The striker has no rust and is not in position to latch the door tight that leaves a gap between the door and body. The door latch after opening the door remains in a closed position and need to manually lift the lock in order to shut the door.

Tl* the contact owns a 1998 chevrolet blazer. The contact stated that the vehicle failed to start and would stall intermittently. In addition, the power door locks would lock and unlock and the windshield wipers activated independently while the vehicle was in motion. The contact further stated that the dimmer switch failed to work, which resulted in a lack of visibility when using the low beam headlights. The VIN was excluded from the federal safety agency campaign number: 00v220000 (exterior lighting). The vehicle was not repaired or diagnosed. The manufacturer was notified. The approximate failure mileage was 127,000.

The master control switch on driver side went out at the same time my front & rear vents stop working. I couldn't control any windows, mirrors, door locks, interior lights, etc. The heat/air/vent quit blowing out front & rear at the exact same time. We had vents (for air) fixed first. A dealership stated that the wires had burnt into. On june 5, 2012 we finally raised the $315.54 to fix the one problem. The control switch burn out also at the same time & will cost $463.45 to fix the control switch. I see this is an ongoing problem with several 2006 trailblazers (you can't order an aftermarket switch due to it has to be "programmed" through the dealer which charges $84.24 to whoever replaces it (even them at the dealership) after you purchase the switch. We live on disability (fixed income) and it takes several months to save for even one problem.

2002 s-10 blazer 4wd concern first let me say I have not changed the drivers door pins and bushings even through I knew they were bad. The door closes and locks on the door striker than mounts to the vehicle side post. Here is what happened, which at a service center getting the transmission serviced and replacing the 4 wd drive shaft, I returned to pick my car up. The door would not close and latch, upon further investigation, the entire door striker assembly fractured the side post metal and pushed into the sidepost assembly. This prevented the door from latching. I went to a chevy dealership in gresham, oregon, we looked at the design, the door striker is only mounted to the sheetmetal with a metal backing support behind it. My question is, how did this vehicle pass any kind of side impact test with this design? The only thing keeping the door from flying open is what I described above. I am shocked that the door striker is not secured to a steel post of some kind. I'm going to take some digital pictures of the striker assembly to keep incase you are interested in looking at them.

Power accessory circuit breaker becomes hot, and then power seats, door locks, mirrors and keyless entry do not work. This existed when I purchased the vehicle in april 2008. I tried replacing the circuit breaker. Also, the power mirror on the passenger side was damaged and was removed, so this may not be the same issue as the recall on the mirrors = to install fused jumper harness.)
