On January 17, 2023 I took my car to J.J.'s Auto to be serviced because the car was backfiring. A service technician at J.J.'s performed a diagnostic and said based on the diagnostic report, the throttle body needed to be replaced. I asked the technician if he was sure the backfiring wasn't caused by something else and he said yes. On January 28, 2023 I gave J.J.'s Auto approval to proceed with replacing the throttle body. J.J.'s Auto then proceeded to replace the throttle body and I was able to pick up my car on February 1, 2023. After I drove the car off the service lot, on my way home the car started backfiring again. When I got home I immediately called J.J.'s to let them know that the car was still backfiring. I was told to return the car the next day and someone would test drive it again. I returned to J.J.'s the next day to drop my car off for someone to test drive it for the backfiring. Service manager ***************************** test drove the car and confirmed backfiring. He told me I would need to pay for ANOTHER diagnostic to be performed in order for them to determine the problem. He said they could not fix the car unless I paid for another diagnostic. At this point I'd already paid $575 for them to replace the throttle body. They then proceeded to tell me I needed to pay an additional $139 for them to conduct ANOTHER diagnostic to determine the cause of the backfiring. At this point, I also asked if I could have the old part that was supposedly replaced. I was told they no longer had the old throttle body and in order to get the a new throttle body they needed to send the company they were purchasing it from, the old part. I should not have to pay for another diagnostic when they told me they found the problem and that replacing the throttle body would fix the problem. I want them install the old throttle body and refund me my money.
