2003 Jeep Liberty Owner Comments

problem #1

May 212007

Liberty 4WD 6-cyl

  • Automatic transmission
  • 74,000 miles


Our 2003 Jeep Liberty failed the state emissions test in April of this year. At this point the "engine indicator light was on. We were told one cylinder was misfiring. We took it to bertera in westfield for service. They ran a diagnostic and also said one cylinder was misfiring. They also recommended a tune-up. Total repairs were $369. They also recommended "a good run of 150 miles to clean out the carbon build up from the miss firing before getting it inspected again. Within 3 weeks the engine light was back on. The car was returned for additional service May 21, 2007. Final diagnosis took until May 24. Problem was cylinder 1 valve burnt and cracked. The final cost to replace the heads on this engine was $3395.95. This does not include the $369 for the tune-up on a bad engine. When we asked for some financial consideration for the tune-up I received a lecture on auto repair is not an exact science. In closing, we keep our vehicles for 10 years, and get 140,000-160,000 miles, therefore we take care of our vehicles with the expectation that mechanical vigilance on our part will guarantee they're longevity. This Jeep has 74,700 mostly highway miles and a ruined engine. To us this is a serious failure in quality.
