In January 2025, my vehicle started experiencing acceleration problems and a check engine light. I took it to Boss Automotive in West Chester, PA, where they diagnosed the check engine light code as a throttle body issue. Despite their thorough inspection, they concluded that the throttle body was in good condition. The mechanic tested and cleared the codes.Two days later the problem returned so I decided to seek a second opinion, I did a google search and found Exton Nissan, I dropped my car off at the dealership and two days later they informed me that the throttle body needed replacement. I was told it would cost over $900 for this service on January 29, 2025. I paid and agreed based on their diagnosis to replace the throttle body. On March 5, 2025, approximately one month and five days later the same issues resurfaced. Car not accelerating and check engine light on. I took the car back to Boss Automotive, and their mechanic confirmed that the original error codes were still present. Based on their diagnosis initial diagnosis by Exton Nissan the codes are to replace the throttle body.I reached out to Exton Nissan, since this was the same issue that happened before and the codes are the same and the throttle body was replaced. I was informed that there was no warranty on the throttle body, I expressed my dissatisfaction with Lauren, the assistant service manager, that I just replaced the throttle body a month ago and that I believe my car was misdiagnosed because the codes are the same and if I replaced the throttle body why would the codes be saying to replace throttle body, Lauren stated she had to speak to the Service Director and would call me back, she then called me back 15 mins later and advised me to bring the car in for further inspection. I asked Lauren if the dealership would tow the car because I believed the issue was due to improper diagnosis on January 29, 2025. She advised that if the issue was different, I would have to pay the towing cost. I insisted that I didn't believe the issues were different and that the problems stemmed from the original issue. She said she would call back once the car was diagnosed.On March 7, 2025, I received a call from Lauren at 9:45am stating that they did another diagnostic test on the car and checked the the throttle body and it was was functioning correctly, the issue they found was the wiring is bad and the repair estimate was nearly $1,000 and take 3-4 hrs.I expressed my frustration with what I perceived as a misdiagnosis and poor service. Lauren assured me she'd escalate the matter to the service director and contact me. However, after waiting five hours without a call, I called and Jason answered the call, he provided me with the repair estimate and when I expressed my concerns about the misdiagnosis he stated he wasn't involved in decision-making and could only provide the cost of fixing my car because Lauren left early due to illness, and he was the only person in the service department at the desk and he was doing the best he could.I requested to speak to Joe Spiller, the service director, but my attempts to escalate the matter were unsuccessful. He was unavailable and I was told by Jason I'd receive a call back.After the call with Jason I was not satisfied so I contacted the dealership and asked to speak to Derek Bush, the owner. I contacted Mr. Bush via phone and email to express my concerns about the service performed on my car. He promptly returned my call, which I appreciated. During our conversation, he stated my car had both a wiring issue and a throttle body issue. However, he emphasized that the decision to replace the throttle body was solely based on the diagnostic machine's recommendation.I disagreed with this decision, believing the diagnosis was inaccurate because the technician didn't say my car had a wiring problem in January and why was the same code " replace throttle body was showing up even though I replaced the throttle body a little over a month ago. Despite my concerns, Mr. Bush maintained that the technician had accurately diagnosed the problem. In light of my dissatisfaction, he offered to help by waiving the tow fee and splitting the labor costs, which he estimated to be around $500. I was not satisfied with their incompetence read more
