NHTSA — Fuel/Propulsion System Problems

CarComplaints.com Seal Of This Might Hurt

CarComplaints.com Notes: Buying the first model year of any vehicle is rarely a good idea. You become a guinea pig for the automaker and they are really not nice to guinea pigs.

The 2008 Enclave has a wide enough range of problems to issue a warning. There's transmission failure under 90k miles, new power steering units costing over $1,300, and enough engine complaints to NHTSA to scare anyone away.

The throttle body on several GM vehicles has failed. I was driving my car down the highway when the traction control light started flashing, then the engine reduced power start light went on, then the car sputtered, slowed down and would not go over 30 mph. This could cause an accident when driving at a high rate of speed, the vehicle slows down quickly and you cannot get power to move over 30. I have researched this and it is a common problem with GM vehicles.

The vehicle repeatedly stalls at random times. This includes at high speed, in the middle of the eisenhower tunnel on I-70, to driving down the street. Repeated visits to the dealership reveal no "codes" so it continues to be ignored. My wife will not drive it anymore so I do. The dealership says "trade it in" but we feel like we would be passing a coffin onto another family. My family has been killed nearly twice from stalling in tunnel and high traffic.

The engine light came on... (4) recalls for other malfunctions..., the current re-call - 10/2014 on side air bags, that was taken care of. The engine light continued to stay on...the dealership found the problem... the gas tank...a brand new gas tank was needed. How can that be, the car is ( 6 ) years - six. The mileage ( 64,000 ).. record shows consistent car services, good care from the initial purchase. The dealership states the cost would be $505. "the car could at any time stop receiving gas into the tank!!!.... the car at any time, could just stop!!!, due to a defected gas tank; assembled at a GM plant, 2008 to me, this is their/ GM responsibility. This is definitely a **safety road issue, not caused by me.... they did some sort of test; automobile was not even at the service area, when the so-called test was administered; it was then declared that the charge is mind.... I spoke to a gmbuick rep, in detroit. Mi., he sent me to dealership, dealership determines who pays. GM transfers its responsibility to a dealership... please advise.... GM lacks the ability to interact with customer; no options, no customer service, no consideration, no satisfaction was given, especially; no manners... dealership did not make the car; nor equipment...please.
