Model years: 2014

Problem: General Motors is recalling certain model year 2014 Chevrolet Suburban vehicles manufactured July 9, 2013, through July 22, 2013; and 2014 Chevrolet Tahoe vehicles manufactured July 16, 2013, through July 23, 2013; and model year 2014 GMC Yukon vehicles manufactured July 13, 2013, through July 18, 2013; and model year 2014 GMC Yukon XL vehicles manufactured on July 22, 2013. The rear brake caliper bolts may not be fully tightened. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 135, "Light Vehicle Brake Systems."

Risk: Loose caliper bolts may cause reduced braking performance and result in lengthened stopping distances, increasing the risk of a crash.

Fix: GM will notify owners, and dealers will inspect the bolts on both rear brake caliper brackets. Any bolts found loose will be replaced and tightened. This service will be performed, at no charge. Owners may contact Chevrolet at 1-800-222-1020 and GMC at 1-800-462-8782. GM's recall number is 13247.

Model years: 2000, 2001, 2002

Problem: Certain pickup trucks and sport utility vehicles may experience unwanted antilock brake system (abs) activation. This condition is more likely to occur in environmentally corrosive areas. This recall will be launched in the "salt belt" states of connecticut, delaware, illinois, indiana, iowa, maryland, massachusetts, maine, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, west virginia, wisconsin and the district of columbia only.

Risk: This can cause increased stopping distances during low-speed brake applications, which could result in a crash.

Fix: Dealers are to remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply rust inhibitor to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the peak-to-peak output voltage to ensure the wheel speed signal is within specifications. The recall began september 22, 2005. Owners may contact chevrolet at 1-800-630-2438 or gmc at 1-866-996-9463.

Model years: 2005

Problem: On certain sport utility vehicles, the brake pedal pushrod retainer may be missing. If the retainer is missing, the brake booster pushrod could disengage from the brake pedal.

Risk: This could result in a loss of brakes which could result in a crash.

Fix: Dealers will inspect the vehicles for the brake pedal pushrod retainer and install one if it is missing free of charge. The manufacturer began contacting owners by telephone on march 10, 2005. Owners may contact chevrolet at 1-800-630-2438 or gmc at 1-866-996-9463.

Model years: 2003, 2004

Problem: Certain sport utility vehicles, pickup trucks, and passenger vans fail to comply with the requirements of federal motor vehicle safety standard no. 135, ?passenger car brake systems.? Some of these vehicles were produced with an out-of-specification brake hydro-boost housing relief valve bore.

Risk: Consequently, the valve o-ring seal may fracture. Steering efforts may be slightly increased while braking or parking. Under certain driving conditions, a fractured seal may require a slight increase in the applied brake pedal effort to achieve the same vehicle deceleration rate as prior to the seat fracture.

Fix: Dealers are to replace the hydro-boost relief valve. The recall began on june 18, 2004. Owners should contact cadillac at 1-866-982-2339; chevrolet at 1-800-630-2438; gmc at 1-866-996-9463; or hummer at 1-866-486-6376.

Model years: 2000

Problem: Vehicle description: light duty pickup trucks and sport utility vehicles. Some of these vehicles have a clearance condition between the front right-hand brake pipe and the body cross sill that could decrease to the point of allowing contact during the life of the vehicle. If contact occurs and the brake pipe becomes damaged, in half of the brake system there can be a loss of brake fluid and pressure. The brake warning lamp will be activated when the brake fluid level reaches the indicator limit.

Risk: During braking, the pedal will be lower than normal and stopping distances will be longer. If this occurs when stopping distance is limited, a crash could occur.

Fix: Dealers will inspect the front right-hand brake pipe for wear. If there are signs of wear, this section of the brake pipe will be replaced with a new designed brake pipe section. If there are not signs of wear on the brake pipe, the dealer will install a spacer clip to ensure sufficient clearance between the brake pipe and the body cross sill.

Model years: 1998

Problem: Vehicle description: light duty pickup trucks and multi-purpose passenger vehicles. One or both front brake rotor/hubs were built with an out-of-specification gray iron that can fail during the life of the vehicle.

Risk: If a driver continues to drive with a cracked rotor, the cracks could continue around the wheel mounting bolt circle and ultimately result in a wheel separation.

Fix: Dealers will inspect the rotors for a core date of "287" and, if found, replace the rotor.
