Seat belts: rear/other
- 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.
Recall number 05V163000 · Recall details
Service brakes, hydraulic
- 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.

It is just like the the service bulletin out for the 2006 and later gmc sierra except it’s for a 2004 gmc Yukon slt 4x4 4.8L. It is going into reduced engine power mode and it has to do with the throttle actuator control module. Throws code P2108
My kids and I was on the interstate and all of sudden my yukon reduce engine power.Dropping to 30 in a speed zone of 70.I was very afraid for our safety and appreciate there concerns for reducing engine power to save the truck,but that's very dangerous. So I paid to replace the throttle body and gas pedal cause that was the codes for the problem. But it's still doing the same thing and I don't have money to keep buying parts.Plus it a gm problem and I really need some help with the fixture..
Gm ignition switch recall: gmc refuses to honor the recall and fix this issue on both my SUV's. I can't be part of the class action until these repairs have been made, what a scam. I own 2 gmc yukon's slt and both qualify for the recall which I was never notified of from gmc. Neither car ever got repaired. The manufacture and local dealerships refused to do the repairs at no cost. This is after I paid these [xxx] over $1000 to fix this problem on one of my SUV's many years ago which did not get fixed because they claim they couldn't find what was wrong with my SUV's but they knew all along. I want gm to honor their legal obligations and fix my SUV's faulty ignition system. I only found out that there was a recal from the class action attorneys. Gm never notified me of any recalls ever!! Please help. Thank you. [xxx] parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
