I recently purchased this vehicle used. Upon inspection, I discovered that the brake lines are severely corroded and require replacement. On further inspection, I discovered that the engine cradle, bushings, and fastening hardware are severely corroded as well. The rest of the vehicle is not corroded in any way, not even rust belt problem areas. From researching online (including other complaints on this website) both of these issues are common in late 90's gm w-body vehicles. How this has not elevated into a safety investigation by now is troubling to me. Ford was required to recall due to rusting brake lines...... Do people have to die for the nhsta to investigate?

I came home after bible study on wednesday night and got up thursday then the security light went blinking. My husband had the key ignition replace then brought new key but car still wouldn't start so had the car towed and repaired. 10 months and three weeks the car did the same but I was driving this time and it shut down in the road with me and my children. It was frighten but we made it safely out of the road before anything happen. I don't understand that this problem occurred again . I am upset about the problem. A car has no business shutting off in the road while a person is driving it accident or no accident because it in danger peoples life. A serious problem for many people whom have these cars made by gm.

The vehicle acted like it had a miss, the service engine light came on, flashing, then stopped flashing but remained on. I drove vehicle home, and the next morning it would not start. I had it towed to a shop and the mechanic said that it had hydro locked due to coolant dripping on the piston from a coolant leak at the intake manifold. This is not a cheap repair.

1998 buick - lesabre ,the intake plenum had a hole in it because it got to hot,and antifreeze went into the block. Buick has had this engineering problem for a long time. No recall , it cost me $785.76 to have fixed. I want my money back. This is bs. There are 1000s of people that have this car. I have 61502 miles on this car. My mechanic said he has fixed atleast 30 over these problems with the buick-lesabre 1992 and up. Times are hard right now, I don't have his kind of money. I just don't want anyone else to come across this problem, with this engineering problem. Buick needs to call a recall on this problem before someone really gets hurt. Lets help each other out ,and call every news station,paper. And get it resolved.

The mechanic advised the starter "exploded" because fluid was leaking from the pleneum into the cylinders and starter. The mechanic advised it would cost over $800.00 to repair.

Here's what happened, the car started consuming dexcool antifreeze, but none was noticed leaking external to the engine. The upper intake manifold made of plastic apparently warped, and/or a hole burned in near the egr stove pipe, thus dumping antifreeze into the engine and hydrolocking the engine. Major problem, complete engine failure would not start or run. This car had been well maintained with both regular oil and coolant changes, the car has been adult driving . Cost to repair $450.00 for just upper intake, add another $450 for the lower intake as well.
