problem #3

LeSabre V6

  • Automatic transmission
  • 156,000 miles

The check engine light came on again and every time it does the garage says it's the catalytic converter . If that is what they say it is again, that will be the 4th time in 4 years that has happened. The last time we made sure we got a GMC one because they said that would last but obviously they were wrong. It has been less than 6 months since it was replaced.
