1998 Buick LeSabre Owner Comments

problem #3

Apr 202004

(reported on)

LeSabre 6-cyl

  • 87,566 miles


While parking, the consumer noticed coolant leaking from underneath the vehicle. The consumer drove the vehicle to the dealer for inspection, and the mechanic determined that the radiator needed to be replaced. The input manifold cracked/split and the engine coolant leaked into the engine. The coolant reservoir kept on going down but the consumer never saw any coolant on the driveway or in the oil. The consumer requested that GM cover the cost of repair.

While returning home from our daughter's in Virginia, our check engine light came on. We pulled onto a side road and turned off the car. Looking under the hood, we found the reserve radiator reservoir to be totally empty. After 20 minutes, we tried to start the car to no avail. We were towed back to the nearest town, selinsgrove, pa, to a pep boys and were told the engine had seized up. The next day the car was towed back to rochester where our mechanic proceeded to find out the problem. We also called the dealership where we bought the car two years ago, and the service manager told us that he had seen this before. The radiator fluid is entirely sucked into the engine through the intake manifold and there is never any indication of over heating or changes on the gauge readings because the engine is not hot, due to the fluid being in there. Consequently, we had to have the engine replaced. Three days after this happened to us, a letter was mailed out to all owners of 2000-2003 Buick for this very same problem. We have a 1998 Buick Lesabre. We called the number given 1-800-832-8425 and also called BBB auto line for General Motors. General Motors will not do anything to help us in this matter because our vehicle is a 1998. The cost we have incurred to remedy this failure is in excess of $3,000. The same engine was used to repair the problem: A 3800 series ll (L36) V6 engine. How do I know the same thing won't happen again" I do not! I do not want to keep the vehicle yet I cannot afford not to. We have bought GM cars and trucks for the last 35 years. We always said: "buy american". I guess that time is over. Is there anything you can do to help us"
