2003 Chevrolet Impala Owner Comments

problem #3

Feb 122007

Impala 6-cyl

  • Automatic transmission
  • 67,275 miles


Noticed it took longer for the car to heat up last winter; this winter started out the same, and I noticed the blower wouldn't work on setting 5 sometimes. Then it quit heating altogether, and the fan would quit but start back up. Now the fan quit blowing altogether. No heat, no defrost, in sub-zero weather, and I'm looking at about $1000 in "repairs" which should be covered as a manufacturer's defect. Thanks GM. I'll be sure to buy another of your vehicles. There is a manifold gasket leak, and the blower motor needs to be replaced.

problem #2

  • Automatic transmission
  • 68,000 miles
The car starting smelling like anti-freeze and then a big puddle appeared in the front passenger side of the car. The only thing we did was drive from nampa, id to billings, mt, which we have done four times before. It has been determined that the heater core needs to be replaced. The car has 68,000 miles on it right now as of July 28th, 2006. In novemeber of 2003, three months after I bought the car, the heater core was replaced at 31,000 by the lithia dealership in helena, mt. The intake manifold was also replaced in May 2006 because the car was overheating and making a ticking noise.

  • Automatic transmission
  • 58,000 miles
Heater quit working, then car started overheating. Turning off heater/defroster causes it to stop overheating so much, but temperature still rises when waiting at lights. Car is also needing oil replacement, after having an oil change 2 months and 1500 mi ago. Mileage is around 60,000. There is oil leaking out in various places around the engine.
