problem #2

Mar 242009

Impala

  • Automatic transmission
  • 77,322 miles

After starting car, accelerating in forward or reverse would cause the traction control system and light to activate. Same thing would happen occasionally when traveling slow around a 90 degree corner. A couple times, the "Service Traction Control" light turned on, but would not persist across a restart.

The service rep. said it might be a wheel hub bearing, but it turned out to be frayed speed sensor wires on the right front wheel. The speed sensor harness was replaced and the problem went away.

problem #1

Impala Sedan 3.2lV6

  • Automatic transmission
  • 84,500 miles

My car is a 2004 Impala with 84,500 miles on it.My speedometer should still be operating on a car that is 4 yrs old. Leaving the driveway you will be on "0" then as soon as you barely get up to speed it will jump to 70 miles a hour, even though I "may" be going 20 miles an hour at the time. This poses a terrible risk to the owner and others. Chevrolet should fix this problem at no cost to the owners before someone gets hurt.
