1999 Oldsmobile 4.8l engine will shut completely off unexpectedly while driving. This occurs both at highways speeds of 65 MPH or at slower speeds of 35 or 35 MPH. All of the power assisted features such as power brakes and steering also stop working when the engine stops. The engine shutting defect does not occur daily and is unpredictable. 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. This is an extreme safety issue that appears to replicate the GM ignition switch recall that this VIN is not included in. From "googling" this defect it appears to affect a large number of similar vehicles with 3.8l GM engines and electrical systems.
1) rough idle when stopping car. Upon restart,strange noise from engine. Would not restart. 2) smoke from starter. Engine locked up. Water loss from radiator. Cracked manifold. 3) replaced upper intake manifold & gasket. Cleaned lower intake. Replaced spark plugs & wires. Changed oil, oil filter, & replaced starter.
Car overheated without any visible signs of this but the red area of the gauge then the check eng light came on. Pulled to side of the road, checked it got it cooled down, then proceeded to the very next rd to gas station for better view of what was going on. Got to it very quickly and the temp was back up. Stopped let it cool and added water to the now empty resovair that was full when we started the trip. And no signs of leakage and no boiling over, let it cool. Added water. Then tried to crank it up, it would not. Had to have it towed to dealer, thought eng had locked up. Was told their was a feature to this car that shuts down the eng when a leak like this occurs. Wondering how many other people are taken because they thought the eng was gone......and it was not. But it somehow damaged the starter when all this happened. …
Consumer heard an explosion when she turned on the ignition and a small fire under hood melted some parts. Smoke was seen coming from under the hood. The vehicle has had all maintenance regularly at the dealer only. The consumer was not aware of the cause.
Vehicle had been parked for awhile. Had got in and inserted key in ignition and started it. Suddenly, vehicle blew up and then caught on fire. Engine compartment had blown. Had no indication of cause of problem. Fire possibly caused by an electrical failure.
My complaint is that when the weather is cold, my horn doesn't work until the whole steering wheel warms up, which can take up to an hour. The service department at my olds dealer is apparently aware of this because they advised the only thing I can do is to replace the $700+ air bag because all the wiring for the horn is run through the air bag. As far as I'm concerned, this is a manufacturer's defect and is extremely dangerous. This should be a recall. There was no "incident" but apparently I have to put in a date so I will just make one up so I can proceed with my complaint.
After starting the vehicle consumer heard a loud popping noise, and noticed smoke coming from under the hood. Consumer opened the hood, and saw that the engine was on fire. The local fire department arrived to extinguish the fire. The cause of the fire was not determined. Dealer and the manufacturer were not notified.
While driving noticed smoke near windshield post of the left side. Then, consumer pulled over, and passenger noticed flames coming from the bottom of the driver's side door. When pulling on the handles to open doors, they will not release because of an electrical problem.consumer was able to get out, but the speakers were on fire. The fire started at mirror control switch possibly caused by a fuse or circuit breaker blowing out.

These vehicles were assembled with a malfunction alarm, lighting and locking (mall) module that can contain a damaged capacitor. If the capacitor is damaged, the "key in the ignition" warning chime and the driver seat belt unbuckled warning chime and indicator lamp May not work. This does not meet the requirements of FMVSS no.
Remedy: Dealers will inspect and, if required, replace the mall module.
