Since last year I have had problems with my car when it is on the road specifically going up a hill it would lose power and it slows down and then it turns off while running. Which is very dangerous because sometimes the car behind me come very close to crashing against me. We took the car to a gm dealer where we bought it they could not give us an answer we have taken the car to 6 repair shops and no one knows what is wrong with the vehicle we have change the tps sensor, the spark plugs, map sensor, new battery, we have cleaned the fuel injectors several times,we change the transmission fluids, we change the pump gas completely, we have changed the ignition coil.we have changed the timing belt twice since we have the car. And the car is running worse now because it stops not only in a hill but on a flat road too.

Seat belts: front: buckle assembly
- What is wrong
- Certain vehicles located in guam and saipan were built with a seat belt buckle with an improper ultrasonic weld of the spring rib and fixation rib of buckle undercover in both front seat belts. A spring rib or fixation rib could break and remain inside the buckle, and the seat belt tongue may not be inserted into the buckle, or the push button may become stuck, resulting in an occupant not being able to unlatch the buckle.
- Risk
- These buckle malfunctions could prevent a person from using the seat belt system, and risk of injury to an unbelted person in a crash would be increased.
- Remedy
- Dealers will replace the front seat belt buckle. The recall began on january 2, 2008. Owners may contact gm daewoo at 1‑671‑648‑8453.
