2000 Cadillac DeVille Owner Comments

problem #10

Jan 232012

DeVille 8-cyl

  • 107,834 miles


Driving into my drive way I noticed that my car pulled in very fast. Normally, I idle in my car into the drive way, this time it was much faster and the engine was very accelerated. I parked the vehicle and the engine was accelerated up to 1850rpm. I pressed the gas pedal to free up the throttle, it made is worst. The vehicle RPM increased up to 2835 RPM and stayed stuck at 2835 RPM. After 10 to 15 seconds the RPM slowly dropped down to 1500 RPM and stayed at these revolution. I had to turn off the vehicle. It's normal idle RPM are 675-700rpm. This is a safety hazard for some one that does not know what to do when driving at a busy highway or regular city streets.

The contact owns a 2000 Cadillac Deville. The contact stated while driving at 25 mph, the engine would abnormally overheat. The contact received a radiator flush and the water pump was replaced yet the failure persisted. The contact stated he would continuously add anti-freeze to the engine to stop it from becoming excessively hot. The contact took the vehicle to a local mechanic where it was discovered that there was an eight inch fracture in the engine block. The manufacturer advised the contact that because the vehicle was over ten years of age, they would not provide any assistance. The contact was concerned that the engine fracture would potentially cause the entire engine to fail. The vehicle was not repaired. The failure mileage was 52,000.

"check coolant" light, overheating, taken to garage "free lance" Cadillac mechanic researched problem that it is a factory related incident that the first owner of the car ignored and should have been sent back to GM and they would have fixed it. I am a second owner to car and I have "inherited" this problem. Blown head gasket............you pour coolant in and it runs right out the tail pipes!

DeVille 8-cyl

  • Automatic transmission
  • 25,000 miles


The vehicle stalled intermittently. The brakes failed, and the vehicle was involved in two front end collisions. There was a funny noise in the engine at idle speed. The engine would lose power and stall. The service manager suggested that there were problems with the 2000-2004 model with this same problem. The front brake linings were worn, the dash pad was peeling at the leading edge near the defrost edge near the defrost grille due to delamination and the coin holder housing had come apart and split at the seam. The crankshaft position sensor was replaced.

Consumer noticed oil on parking garage floor. Took vehicle to dealership for inspection. Dealership indicated oil was leaking from the oil pan gasket rear seal, upper crank case valve cover, and rear seal due to a flaw in the North star engine. Oil pan casket had been replaced, and upper crank case will be replaced. This was a common failure with these engines.

  • Automatic transmission
  • 43,077 miles
While driving at 62 mph vehicle stalled. This caused loss of steering and brakes. Consumer took the vehicle O the dealership several times over the course of a year. The dealer replaced different parts yet the problem recurred. The coolant level light had a poor connection which caused the then it is moist or damp outside the vehicle sputters and stalls. Coolant light to illuminate. Sometimes the door locks would unlock once the vehicle was placed in park, sometimes they didn't. the vehicles heated seat shut off after about five minutes or sometimes they didn't work at all. The information center would reset itself sometimes. The dealer replaced the instrument panel cluster. The exterior driver's side mirror was cloudy which caused poor visibility. The dealer replaced the entire mirror.
