“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.”

“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. …”

“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. …”
