Business ProfileforTacoma Dodge Chrysler Jeep Ram

On August 3rd I scheduled my 2018 Jeep Wrangler JLU for a 100k scheduled maintenance and a check engine light. I was informed by the advisor that the wiring harness throughout needed replaced overall cost of approximately *******. I made a cash deposit of 1K. On August 15 pickup the vehicle told everything was fine, two days later check engine light returned. Arrived back to dealership on August 19, read code and was told it was the fuel tank pressure sensor with an ****** estimate. Provided a courtesy diagnostic and three days later was told it was something else triggering the check engine light. The *** Vacuum pump an estimate of ******. Spoke with another advisor who explained the vacuum pump was triggering all the other codes. Dont trust this information as it was conflicting to what the primary advisor was telling me. Called August 23, 2024 and was told the *** Vacuum pump was being replaced and should resolve the issues. I questioned that if I was charged to replace a wiring harness for 6K dollars for nothing and the problem actually was a vacuum pump. Was told to speak the the primary advisor, but vehicle would be ready Monday 26, 2024 by 5pm. Called to speak with the dealer advisor late afternoon and was updated that the check engine light came on again and it maybe a bad or faulty part or something. 8/272024. Contacted and told the vacuum pump was replaced but the check engine light came again and this time its a faulty/loose connection of wiring near the steering column that appears to have come loose but secured partly causing the the check engine light. Another$ 700 of pocket repair. Advised they will secure it somehow at no cost. Went to pick up vehicle paid 487 dollars for the *** vacuum pump that they claimed was the culprit. I feel the mechanic improperly diagnosed my vehicle charge for services not needed when the origin do the issue was a faulty connector to start.
