2003 GMC Yukon problems

What is wrong

On certain crew cab pickup trucks and sport utility vehicles, the 2nd row center occupant seat belt routing may make it difficult to position the lap portion of the safety belt low around the hips of occupants, especially smaller occupants, seated in this position. Appropriate use of a child seat or booster seat, as recommended for small children, does improve the fit condition for this user group. In addition to instructions on proper infant and young child restraint (with child seats or boosters), special verbiage for restraining older child is included in the owner's manual. Also, the suggested seat belt fit/routing for adults, irrespective of seating position, is described in the owner's manual text.

Risk

A lap portion of the seat belt routing that is not low and snug on the hips can allow the lap belt to ride up on an occupant's abdomen instead of fitting low around their hipbones, and therefore, can expose them to more risk of abdominal and internal organ injury.

Remedy

Dealers will cut open the guide loop, remove a portion of the loop, and then the remaining two sides should be folded over and secured with a retainer free of charge. The recall began on july 21, 2005. Owners may contact cadillac at 1‑866‑982‑2339, chevrolet at 1‑800‑630‑2438, gmc at 1‑866‑996‑9463, or hummer at 1‑800‑732‑5493.

What is wrong

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.

Remedy

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.

What is wrong

Certain pickup truck, van, and mini van conversions equipped with southern comfort built running boards that contain certain courtesy lights manufactured by american technology components, inc. These units contain a courtesy light or lights that might overheat when the wire harness is exposed to excessive moisture and road salt.

Risk

This overheating condition can cause the running board to melt or cause a fire.

Remedy

Dealers will replace the wiring harness on these running boards. Owner notification began march 7, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact southern comfort at 1‑800‑745‑6096.

Recall number 03V094000 · Recall details

What is wrong

Certain sport utility vehicles fail to comply with requirements of federal motor vehicle safety standard no. 214, "side impact protection." these vehicles are built with four welds on the rear door upper hinge. On some of these vehicles, one or two of the welds may not be to specification.

Risk

As a result, the door strength may be degraded during a side impact vehicle crash.

Remedy

Dealers will inspect the welds on the left rear door upper hinge. If a weld is found out-of-specification, a bolt will be installed to secure the hinge. Owner notification began february 17, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact cadillac at 1‑800‑458‑8006, chevrolet at 1‑800‑222‑1020, or gmc at 1‑800‑462‑8782.

Recall number 03V037000 · Recall details

The Office of Defects Investigation (ODI) received Defect Petition DP10-003 on March 2, 2010, requesting the investigation of model year (MY) 2003 Chevrolet Silverado 2500HD 4WD pickup trucks for corrosion failures of the vehicle brake lines.DP10-003 was granted and on March 30, 2010, Preliminary Evaluation PE10-010 was opened on more than six million model year 1999 through 2003 light trucks and sport utility vehicles manufactured and sold by General Motors Corporation (GM).On July 2, 2010, ODI received GM's response to an information request, which included GM's assessment of the frequency and safety consequences of the alleged defect. GM stated that:(1) the brake system of the subject vehicles is split front/rear and should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit; (2) the subject vehicles were designed to meet the hydraulic circuit partial failure requirements of Federal Motor Vehicle Safety Standards 105 and 135, Light Vehicle Brake Systems; and (3) should a brake fluid leak occur for any reason, the brake system malfunction indicator lamp (MIL) would illuminate and warn the driver before the brake fluid level was low enough to cause a loss of line pressure.ODI's and GM's analysis indicates that 85 percent of the complaints occurred on vehicles used primarily in States that use salt on the roads during Winter months (Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin).Overall the complaint rates per 100,000 vehicles for Salt Belt States is 43.0 and Non-Salt Belt is 3.0.In approximately 25 percent of the complaints the brake pipe failure occurred suddenly, with no warning (i.e., no MIL, Brake Fluid Loss Warning), and resulted in extended stopping distances.In 30 of these the increase in stopping distance that resulted was a factor in the crash and in 10 others the vehicle was intentionally steered off the road or into another lane of travel in order to avoid a crash.This investigation has been upgraded to an Engineering Analysis (EA11-001) for subject vehicles sold or currently registered in Salt Belt States to further assess the scope, frequency and safety risks associated with sudden failures of corroded brake pipes that can result in decreased brake effectiveness. ODI will continue to gather information on subject vehicles outside the Salt Belt as well.

PE10010

Odi's review of complaint data received since the close of ea04-011 revealed no indication that the investigation should be re-opened.more details can be found in the federal register notice enclosed in the dp05-009 public file.odi reserves the right to reopen the investigation in the future should conditions warrant.

DP05009

In a letter dated april 20, 2005, gm notified the federal safety agency that it had decided that defects that relate to motor vehicle safety exist in certain model year (my) 1999-2002 c/k 1500 series (pbr parking brake system) and my 2001-2005 c/k 2500 and 3500 series (trw parking brake system) pickups with manual transmissions.according to gm, some of these vehicles may have conditions that cause the friction linings to wear to an extent where the parking brake can become ineffective in immobilizing a parked vehicle.gm's action covers an estimated total of 142,585 vehicles.dealers will install a low-force spring clip retainer for vehicles equipped with the pbr parking brake system and install a redesigned parking brake cable assembly on vehicles equipped with the trw parking brake system. A total of 58 non-duplicative complaints were received by odi and gm concerning the approximately 59,000 my 1999-2002 c/k 1500 series pickup trucks with the pbr parking brake system.these included 22 alleged rollaway incidents, resulting in a rate of 38.5 rollaway incidents per 100,000 vehicles.odi is aware of 24 complaints regarding the my 2001-2005 c/k 2500 and 3500 series manual transmission trucks recalled by gm, including 5 alleging rollaway incidents.though the conditions described in gm's letter are also present in the c/k trucks with automatic transmissions, the rollaway rate in those vehicles was similar to those observed in peer vehicles studied by odi in this investigation.this engineering analysis is closed. For additional information, see the attached closing report.
