The contact owns a 2006 Chevrolet Trailblazer ext. While driving various speeds, the vehicle would stall and shut off without warning. The vehicle would have to be jumpstarted in order to restart. The failure recurred, but the vehicle would not restart. The contact took the vehicle to a certified mechanic who was unable to identify the cause of the failure. The mechanic replaced the vehicle's battery, auxiliary water pump, starter, and alternator; however, the failure recurred. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 150,000.

I have bought 2 new batteries with in a month of each other due to my battery being dead over and over again. I was told my alternator was fine only that something keeps draining the life out of my battery.this has been going on for months. If I let the trailblazer sit for 1 to 2 days the battery is dead again.I also noticed that the face of my radio has started to get hot. When we first had auto zone change the battery we noticed that it caused our air vents to stop working. I looked this up on line and it looks like I'm not the only one who has this problem. I see it's a big problem.I don't know if there is a recall, but I'm scared it is a electrical problem that could hurt me and my 4 kids if it happens while driving. Can you please help me with this.

Dear sirs or madam, I am writing to you regarding the recall that was issued for the door switch on above named vehicle. The switch on my vehicle malfunctioned in 2011, before the recall was issued. Later, upon taking the vehicle to wailer Chevy in keene, nh, I was informed that there was a recall and I am eligible for a reimbursement of the out of pocket expense of replacing the part. In short, GM initially denied me the reimbursement for superficial reasons. Later after I contacted and filed complaints with the agencies listed below, GM offered and sent a check that covers only the price we paid for the part, but not the labor it took to install it. I have not yet cashed that check, as there is language on it that indicates the issue would be resolved upon cashing. It is not resolved. The balance still owed is $272.18. I was told by some of the agencies listed below that NHTSA was the federal entity responsible for insuring manufacturer compliance with recalls. I'm filing this complaint with NHTSA so that the recall be honored in this case and the balance of the out of pocket expense paid to repair the defect, be reimbursed to me. GM file number: [xxx] eastern Michigan BBB complaint number: 10058153 Michigan department of state file number:[xxx] NY attorney general file number:[xxx] I also have the supporting documentation (ie. Receipts), that can be forwarded to your office if/when needed. Please feel free to contact me regarding this issue.

Both rear brake lights failed simultaneously, even after fuses were checked both under the hood and behind the drivers side fuse box (fuse #12 & fuse #34). This is a road hazard and faulty wiring should be covered. Front left headlight was found to have switch with melted wiring as well, changes by mechanic and I was informed it could have caused a fire. This vehicle has 3 recalls thus far that are extremely dangerous if such faults can cause a fire within the electrical wirings. I would like to get compensated for the work done, the brake lights faulty wiring should be covered under the recall as the local Chevy dealer refuses to fix it.

Well probably about six to eight months ago my speakers and ac/heater started going out, working sometimes and not others. Eventually the ac/heater stopped working all together, and as for the speakers they were doing the same working sometimes or only one side working or just the front speakers working. Well now it only works when its hot and when its cold only the tweekers work. From the blogs I have read this is a big issue with these GM vehicles and something needs to be done. A recall or something.

The driver's door window and door lock has been working intermittently over the last 1 1/2 yrs. This last March, the window stopped working. Then the door lock followed and then the entire door. I have no control over any aspect of the car with that door. I makes a buzz-zapping sound. I cannot lock the windows at all in the back, so now my young children play with the windows and hang out them. The doors are supposed to lock when the truck is put into gear, but that does not always happen. Sometimes it will happen 10 minutes into a trip, sometimes not at all. In the last month the front passenger side window stopped working also. My sons are now complaining of hearing a buzz, click, click, click, sound coming from the back doors. I assume it is the vehicle attempting to lock the doors since we are driving but it is unable to. The driver side mirror also has a mind of its own due to the malfunction of the electrical or the door. It will change its positioning all by itself. I always have to readjust it manually just to find it pointing at the ground later on. I took it to my Chevrolet dealer and was told my vehicle is not included in the recall because of where I purchased it and where I limy live. This is a safety issue apart from the obvious electrical zapping that can be heard, but it is also for children when the vehicle is in motion. I am unemployed and it is going to cost over $150 for them to look at it, and he said there is no recall so to fix it, I will have to pay. There is constant exposure to salt air here in Florida. My kids lives are at stake. I do not care where I live, this is there safety. What if they open the window and get hurt because I cannot lock the window because of problems with my car door.the recall needs to be nation wide and it needs to resolved before someone get hurts.

I've had my trailblazer for two years now about 4/2010 the windows would go up and down on their own and the power lock stopped working so Chevy replaced the main control switch then about 6/2011 I had to replace the wheel bearings and the sensor twice and about 01/2012 the wipers and washer fluid wouldn't shut off got a new wiper motor put in and now the truck has been sitting since 4/2012 had to have it towed from albany because the truck just all of a sudden slowed down even with my foot on the gas pedal and now I have ten different codes that came up two for the camshaft sensor and solenoid the knock sensor the crankshaft sensor and a few other ones... we called Chevrolet and they have no clue what is going on nor what is wrong with it.

All controls on drivers side door quit working. I got online & found a recall on this for my vehicle. I called the phone number for the recall & they informed me that my car was'nt covered because of the VIN #. they told me if I went to a dealer & paid for a diagnostic test they may offer some assistance to have it fixed. They know it is a defect but are trying to get out of fixing mine because of a VIN #. I can't afford to pay for the diagnostic test & then have them tell me I owe more because I have a VIN# they don't want to fix.

As I was driving on the highway, my doors unlocked and locked several times over a period of 30 minutes. I then heard loud chirps from stereo speakers and then the smell of burning plastic. At this point I lost all window controls and audio(door chimes, radio and onstar). To this date I have not been able to use radio or driver side window controls but still notice a smell of melting rubber or plastic. I have two children with autism and I do not feel safe taking it on family outings.

Most recent is a driver's side door/window controls that have completely stopped working. Controls have been sporadic for over a month and have now, and it stopped completely with the window in the down position. I have been lucky not to experience the burning/melting issue others have before it stopped working all together - but my window is now in the down position and cannot be closed. In addition to the door/window controls, the rear window wiper stopped working about a year ago, the fuel sensor went out over a year and a half ago so tank always registers empty and check engine light is always on. (I have received the offer from Chevy to have the fuel sensor repaired, but because I will be responsible for half of the repair costs, I have yet to have it done -- Chevy should pay 100%, not 50%). I've already replaced the tie rods about a year ago, but was just told that they need to be replaced again. I've had issues with the car violently shaking @ 60 mph shortly after I bought it (used) from a dealer. After quite the run around and four extended stays at the dealers repair shop it was magically taken care of after I threatened to file "lemon law" paperwork. I'm just done. The consumer stated shortly after, the windows controls for the other three windows began to work again sporadically, except for the driver's window which was propped closed. On occasion, when the driver's side widow button was touched my mistake, the window would move slightly until being stopped by the 2X4. The consumer finally had the recall repairs done, after waiting on the parts. The dealer removed the 2X4 from the driver's side and the consumer was charged $105.55 to get the window operational again. Updated 05/23/13
