2006 Buick Rainier

The subject vehicles are model year (MY) 2002-2009 Chevrolet Trailblazer, GMC Envoy, 2004-2007 Buick Rainier, 2003-2008 Isuzu Ascender, 2005-2009 Saab 9-7X, 2002-2004 Oldsmobile Bravada, 2003-2006 Chevrolet SSR, 2005-2009 Buick Lacrosse, and 2006-2008 Pontiac Grand Prix. This scope includes the Trailblazer/Envoy variants: 2002-2006 Envoy XL/Trailblazer EXT and 2004-2005 Envoy XUV. The original scope of this investigation was expanded to include all vehicles equipped with the subject Headlight Driver Module (HDM). The focus of the investigation was to determine whether actions performed by General Motors adequately addressed any unreasonable risk to motor vehicle safety in the subject vehicles concerning the headlights and the HDM that controls them.Under normal electrical load and environmental conditions, the HDM can overheat inside the Underhood Electrical Center (UEC). This can cause the module to fail and result in a simultaneous loss of both low beam headlights and both daytime running lights (DRLs), often with no warning or prior detectability to the driver. This failure can be intermittent or permanent. No other exterior lights are affected. High beams, turn signals, brake lights, and reverse lights are still operational.General Motors addressed this issue with 2 recalls (14V755 & 15V519) and a special coverage program (N172091910). In view of the recalls and special coverage program implemented by GM and the vehicle high beams continuing to operate, ODI has tentatively concluded that the actions taken by GM mitigate any unreasonable risk to safety posed by HDM failure in the subject vehicles.Accordingly, the investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.

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. The ODI complaints cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID, see the attached list for ODI numbers.

The office of defects investigations (ODI) analyzed complaint data provided by General Motors (GM) as well as complaints submitted to ODI from consumers.In total, there were 5,089 unique reports indicating an inaccurate fuel level reading while driving.General Motors stated that this condition occurs when the contacts of the fuel sensor wear prematurely.Most of the complaints indicated an empty fuel gauge reading after filling the tank.Less than 10 percent of theODI complaints involved an engine stall incident.During this investigation, GM developed a remedy procedure and issued special coverage bulletin instructing dealers to install a new design fuel level sensor.The bulletin was sent to dealers on August 10, 2011 and the owner letter mailing began on August 15, 2011.See the investigative file for copies of GM's bulletin and owner letter.This preliminary evaluation is closed.

The Office of Defects Investigation has received 668 complaints alleging inaccurate fuel gauge reading while driving in model year 2005-07 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, and Saab 9-7x vehicles.Of the 668 complaints, 58 incidents were alleged to result in a vehicle stall.Of the 58 stalling incidents, 43 complaints reported stalling because the fuel level reading indicated more fuel availability than what is actually in the fuel tank. One complaint alleged a vehicle crash after the vehicle stalled while exiting the interstate, became disabled, and was struck from behind.Summarily, the complaints show an apparent increasing trend, with most complaints received within the past year.A Preliminary Evaluation has been opened to assess the scope, frequency and potential safety consequences associated with the alleged defect.

The contact owns a 2006 Buick Rainer. The contact stated that while driving at various speeds, the steering wheel jerked independently without warning, causing the contact to lose control of the vehicle. In addition, the contact stated that there was an abnormal grinding sound coming from the brake pedal while depressing the brake pedal. The contact had taken the vehicle to two independent mechanics, where the wheel bearings and ball joints were replaced; however, the failure persisted. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

During periods of time with ignition switch on, the wipers will loose the ability to both regulate speed and shut off. The wiper cover AC Delco/GM part number 19120931 will fail and loose control of the wipers (fail to shut off while driving). Because you cannot shut off the wipers, the driver's vision is obscured, and the noise from the wipers on the dry glass is very distracting. This will cause drivers attention to shift from focus on driving to manipulating the wiper switch. GM has not ordered a stock or replacement wiper covers from AC Delco, so trying to locate a fix for this problem is very hard. This is a GM design problem and is very expensive to fix. As a minimum GM needs to stock this part. All of these wiper covers will fail eventually, and accidents from this problem will occur.

In driving cross country, filled up the fuel tank and resumed travel when the fuel gauge immediately went to empty (I didn’t even have time to drive up the highway ramp back onto the highway). The alerts started ringing and blinking and dash board told me there was no fuel. I went to a gravel area and inspected the engine compartment, under the car and the interior to be sure I was not missing anything, then restarted the SUV. Could not find any issues anywhere, including leaking fuel. I took off the fuel cap and reattached it to be sure there was no problem there. I had no choice but to get on the highway and continue my journey. The problem continued for the following 1000 ish miles. When I got home I contacted my dealer and set up an appointment to look at vehicle. They found the vehicle needing a sensor kit which was a recall back a few years ago. I had the issue repaired which took 3 days. They may have the removed items. Attached please find the invoice from the repair that shows the message numbers, etc from the inspection prior to and during repair. Since this issue was a recall, but I understand not for my vehicle but for many similar SUV’s and Pickups of the same area of manufacture; I feel the same components were used in my vehicle and should be paid for and included in this recall. Attached please find the invoice if I can figure out how to get it attached to this type of format.

When I fill my gas up my gas gauge goes to empty, the low fuel light comes on, and my check engine light comes on. I can run out of gas and another can hit me. This is very unsafe, not just for me but others. Buick needs to fix this before someone gets seriously hurt or killed. This is a law suit waiting to happen.
