Defect. General Motors LLC (GM) is recalling certain model year 2006-2007 Buick Rainier, Chevrolet Trailblazer and GMC Envoy vehicles, and 2006 GMC Envoy XL and Chevrolet Trailblazer EXT vehicles. Fluid may enter into the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board, causing window switches to become inoperative. Previously, the affected vehicles may have had their master power window switch module treated with a protective coating, instead of having it replaced.

Risk. The protective coating may not eliminate the risk that the circuit board could short and result in a fire, even while the vehicle is unattended.

Remedy. GM will notify owners, and dealers will install a new driver's door switch module, free of charge. The recall began on November 2, 2015. Owners may contact Buick customer service at 1-800-521-7300, Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is 15700.

Defect. General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.

Risk. Headlamps that do not illuminate reduce the driver's ability to see the roadway and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash.

Remedy. GM will notify owners, and dealers will replace the HDM, free of charge. The recall began on May 17, 2016. Owners may contact Buick customer service at 1-800-521-7300 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14291.

Defect. General Motors LLC (GM) is recalling certain model year 2005-2007 SAAB 9-7x; 2006 Chevrolet Trailblazer EXT and GMC Envoy XL; and 2006-2007 Chevrolet Trailblazer, GMC Envoy, Buick Rainier and Isuzu Ascender vehicles. Fluid may enter the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing odor, smoke, or a fire.

Risk. A short in the circuit board could lead to a fire, increasing the risk of personal injury. A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made.

Remedy. GM will notify owners, and dealers will inspect the part number on the door module, and install a new door module if necessary, free of charge. Parts for the remedy are not currently available. An interim letter was mailed to owners in August 2014. A second owner letter will be mailed when parts are available. Owners may contact GM customer service at 1-800-521-7300 (Buick), 1-800-222-1020 (Chevrolet), 1-800-462-8782 (GMC), 1-800-955-9007 (SAAB), and 1-800-255-6727 (Isuzu). GM's number for this recall is 14309. NOTE: This recall provides a new remedy for all vehicles covered by recall 13V-248. Vehicles whose modules were modified but not replaced as part of the previous recall remedy must have their vehicles remedied again under this campaign.

I've had the brakes replaced because I thought they were an issue I was having with my ABS. But my car will randomly lock its brakes as I'm driving, no matter what speed. I'm scared to drive it. It also almost loses all power after breaking but then speeds up on its own making it almost impossible to slow down or brake.

Reading this record

4 deaths reported in complaints filed with NHTSA.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
