problem #4

Trailblazer LT

  • Automatic transmission
  • 95,000 miles

About 3-4 times per week I can hear my engine through the front speakers, there will also be a crackling noise. After leaving the radio off for about 15 minutes, I can turn it back on and the noise is gone. Recently, I can hear my engine through the speakers even when the radio is off.

A continuation of 11/07 problem of engine noise in the speakers. If I accelerated, I would hear it in the speakers... along with a continual whine. They replaced one more speaker.

... A continuation of the problem of engine noise in the speakers. If I would accelerate, I would hear it in the speakers, along with a continual whine. I had the vehicle in for service on11/07, 02/08, 04/08, and numerous other times, but the noise always came back. They kept replacing speakers while it was under warranty, but that didn't take care of the problem. Now that it is not under warranty, I get to live with the problem. I would think it would be a short or something of that nature, but they never did get the problem taken care of. To make matters worse, the problem was intermittent... sometimes the speakers would be fine, and other times I would (and still do) get to listen to the whine.

The speakers had engine noise in them. If I would accelerate, I would hear it in the speakers. They replaced two of the speakers, but the problem continued.
