Filed Jan 18, 2016 · Electrical, Engine · 145,000 miles · MN

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.

I brought my car in to the dealership for an oil leak and while there the mechanic also checked the coolant level. It was low. He pressure tested the system and found the coolant cap to be not sealing properly. I paid for my repairs and left. The next morning the check engine light came on. I brought the car back to the dealership. They found the engine was misfiring. They checked the coolant level again and it was dry. The intake manifold had melted and coolant had leaked into the engine and was consumed by the engine. Now I need a new intake manifold, gaskets, spark plugs, wires, and an oil change to the tune of $800+. I have searched on the internet and found many similar complaints. Why does gm not do anything. The intake manifold was plastic. Plastic does not belong in an engine. I hope you make them recall this.

Was driving my 99 olds 88 up a hill in tn and it started to shake and lose power. The check engine light came home and the engine was excessively hot. All of the radiator would take the fluid but nothing would leak out. I pulled the car over and waited for it to cool down but then after the 3rd time trying to start it, it made a clunk noise and wouldn't start any more. I was told it was a hydraulic lock up. Car sat for 5 months and finally got the money to have it towed to a collision center to have it looked at. I wish to be reimbursed after it is fixed.
