Due to the failure, the contact lost power steering assist as the steering wheel would spin with no control. The vehicle had yet to be diagnosed or repaired for the failure. The manufacturer had yet to be notified of the failure. The failure mileage was approximately 118,300.
Body is broken where the front sub-frame bolts to. Customer was told that there is permanent body damage to the body frame. They then sold the vehicle undisclosed the fact that the vehicle is too damaged to drive on the road safely.
The car currently has a gas leak. When I search the vin it doesn't show any recalls currently but based on the tsb. The rail should've been replaced with a bosch. I am a service tech at a private shop.
The only check engine code present was a "egr valve" code. The egr valve was replaced at the cost of $344.00. The engine shutting off unexpectedly defect has continued to occur after the check engine repair was completed.
Today, there is a recall # 1999011 dated 3/13/1999 for power train (transmission 4t65e manual valve link replacement) nhtsa 99v089000. This owner nor the previous owner did not receive any kind of notice for this recall. Was the service performed? What happened? Thank you & have a great day !!!
Heard loud boom and smoke started pouring out from under hood. Opened hood and engine was on fire. Extinguished flames and found the intake mainifold had litterally blown apart. There was a recall that should have dealt with this problem.
The contact stated that while traveling 55 mph, the check engine warning light illuminated as the engine overheated. The vehicle was towed to the dealer who confirmed that the failure was caused by a hole that had melted in the intake manifold, causing coolant to leak into the manifold.
My oldsmobile 88 year 1999 had engine failure in 2005 with only 59,930 miles. The upper plemum desintegrated allowing coolant into the cylinders, locking up engine. No warning except rapid raise in engine temperature only about a minute to pull over into a parking lot.
