Driver's Master Power Window SwitchOpened June 11, 2012, closed June 21, 2013

On August 15, 2012 General Motors (GM) announced a regional recall action (12V‑406) involving model year (MY) 2006-2007 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Isuzu Ascender and MY2005-2007 SAAB 9-7x vehicles originally sold or currently registered in the salt belt states of Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, and the District of Columbia. The recall remedy requires the inspection and repair or replacement of the master power window switch, which GM refers to as a driver door module (DDM). At the same time, GM implemented a special coverage program to replace failed DDMs for vehicles registered outside of these states. ODI was not satisfied with GM's exclusion of non-salt belt vehicles and continued its investigation. On June 13, 2013, GM submitted a related recall notification (13V‑248) to reclassify the initial special coverage program into a safety recall for vehicles that were not previously repaired under special coverage.The Office of Defects Investigation (ODI) opened Engineering Analysis EA12-004 on June 11, 2012 to further investigate allegations of DDM thermal incidents in model year (MY) 2006-2007 Chevrolet Trailblazer vehicles. Thermal incidents involve cases where fire-related events such as smoke and melt are present. ODI has received 170 reports alleging a thermal event occurred. Complainants stated that the DDM melted and in some cases produced odor and/or smoke. Fourteen of these incidents led to a fire where visible flames were reported or the damage extended significantly beyond the DDM. In addition to the 170 reports listed above, ODI received 63 reports alleging the DDM acted erratically or became inoperative. In response to ODI's Information Request (IR), GM provided 619 unique consumer complaints that related to the alleged problem. Seventy-seven of those reports led to a fire with flame, and 4 reported injuries of smoke inhalation and/or slight burns from contact with hot switches. GM also submitted 20,400 warranty claims for replacement of the DDM, most of which involved inoperative switches. The problem condition is caused by fluids, such as rain water, entering the driver's door module and subsequently causing corrosion that could result in an electrical short in the printed circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. However, the electrical short may also cause overheating that could melt components of the door module, producing odor, smoke or in some cases fire with flame. The circuit board was redesigned and GM implemented the new design into vehicle production on May 14, 2007. All failures cited above occurred in vehicles produced before this build date (i.e., with the original design DDM). GM also reported that all MY 2006-2007 GMT360/370 platform vehicles and MY 2005 SAAB 9-7x vehicles utilized the same DDM and therefore ODI expanded the subject population to include these vehicles.This investigation is closed on the basis of GM's announcement of safety recalls 12V‑406 and 13V‑248.

Driver's Master Power Window SwitchOpened February 9, 2012, closed June 11, 2012

The Office of Defects Investigation (ODI) opened this investigation on February 9, 2012 in response to complaints alleging driver door module melting and/or burning in MY 2006-2007 Chevrolet Trailblazers. In response to ODI's Information Request letter, General Motors presented 167 reports and 698 warranty claims that related to the alleged problem. ODI has received a total of 83 complaints, 66 alleging the door module had melted or burned, and the remaining 17 stating that the window switches acted erratically or were inoperative. Twenty-eight of the reports received have led to driver door fires, some of which allege the vehicle was keyed off and unattended. Based on the agency's current analysis, ODI has upgraded its investigation to an Engineering Analysis (EA12-004) to determine whether the subject vehicles contain a defect that presents an unreasonable risk to safety.The vehicle models and production dates of affected vehicles will be evaluated, particularly other GMT360 vehicles. The ODI reports cited above can be reviewed online at www-odi.the federal safety agency.dot.gov/owners/Searchreference under the following identification (ODI) numbers: 10247838, 10260600, 10274337, 10275626, 10284010, 10396958, 10406203, 10409023, 10414691, 10417938, 10423865, 10426281, 10434446, 10445657, 10447754, 10447757, 10447770, 10447788, 10447813, 10447831, 10447865, 10447880, 10447892, 10447938, 10447994, 10447996, 10447997, 10448028, 10448086, 10448138, 10448176, 10448201, 10448337, 10448455, 10448464, 10448478, 10448540, 10448900, 10448941, 10449150, 10449166, 10449169, 10449236, 10449722, 10450055, 10450202, 10450284, 10451584, 10451878, 10451918, 10452197, 10452301, 10452586, 10452743, 10452895, 10453161, 10453227, 10453261, 10453578, 10453746, 10453951, 10454196, 10454211, 10454539, 10454673, 10455122, 10455150, 10455279, 10455469, 10456285, 10456529, 10457116, 10457644, 10457811, 10458224, 10458485, 10458599, 10458743, 10458846, 10460062, 10460141, 10460732, 10460843

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.

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 the federal safety agency was the federal entity responsible for insuring manufacturer compliance with recalls. I'm filing this complaint with the federal safety agency 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. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Auto would start but turn off right away. I was told that the computer module was shorting out and the auto would start on it's own.

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.
