1996 Buick Regal Owner Comments

problem #2

Sep 012003

Regal 6-cyl

  • Automatic transmission
  • 72,000 miles


Buick Regal 1996.engine and engine cooling:cooling system hortly after just 72,000 miles, a leak developed near the upper intake manifold, causing excessive coolant loss (up to 1 gallon per week). I believe this to be a saftey hazard resulting from a design flaw. The owner's manual includes several warnings that coolant contains ethylene glycol that will burn if it comes in contact with hot engine parts. I am also concerned this problem may have caused engine damage that will manifest itself later. I believe GM should address this as a safety hazard before someone is killed or seiously injured by an engine fire. Thank you. Djs

The engine was not running properly which caused a crack in upper intake manifold forcing excessive coolant into the top end of the engine and upper combustion chamber. This is an on-going problem with the 1996 Buick Regal. This could have resulted in a fire as indicated by the previous recall notice for the same problem. As a result of this incident, the following service was required: Repair electrical failure, clean excessive coolant from upper combustion chambers, remove coolant from top end of engine, replace upper intake assemble and manifold, replace spark plugs, perform injector service, replace the PCV valve, oil and oil filter. Although I have an extended warranty, I was still charged $557.17 for the repair. Due to the numerous service bulletins, consumer complaints, and previous recall notice for the same situation, this defect should have been detected on March 7, 2002. At that time, I had the routine 60,000 mile service performed even though the car only had 50,480 miles. The total cost for the routine service was $807. For these reasons, I should be entitled to a reimbursement of the $557.01 charge. If needed, I will be more than happy to forward a copy of my service records for your review. Additionally, I am concerned this recent event has caused damage to the engine and will have long term effects on engine performance requiring additional maintenance. It??S hard to believe this did not cause damage to the valves and/or lifters. Once the extended warranty expires, I will no longer have financial protection for repairs resulting from faulty manufacturing. I hope this safety hazard is resolved before someone is killed by an engine fire. Thank you for your assistance in this matter.
