problem #1

Feb 122019

Sierra 2500 HD 6.0L

  • Automatic transmission
  • 20,000 miles

Thought I had gotten bad diesel; determined that was not the issue. Dealer identified the problem and replaced the fuel injector, unfortunately, the replacement part was defective and they initially thought it was something else. Took 2 weeks prior to them determining that the repair part was defective.
