Business ProfileforLarchmont Chrysler Jeep Dodge

I bought my 2018 Jeep Grand Cherokee at Larchmont Chrysler in July 2019. In May 2021, service was performed on the "Start-Stop" feature. In September 2022, the same light and the check engine light went on. I took my car in on September 12, 2022 and spent $1408.88 to fix it. In addition, they kept my car for almost a week and I had to rent a car, another almost $204. After I picked up the car, the same lights went again. I brought the car back in, and after over a week of being in the shop, I was told now the car needed a cylinder head for the engine. This time the service manager agreed to pay for my rental. I called constantly, only to be told my car is not ready. I went to the dealership October 29, 2022 and spoke to the chief mechanic, *******, who informed me the I would have my car back on Monday, October 31, 2022. I did not hear from the service department on the Monday, and gave them until Tuesday, November 1, 2022. I called on Tuesday only to be told by the service *********************** that now my car needed 2 more parts, one of which he does not have an ETA on. He also said he was no longer authorizing my rental as it was "not his problem". When I told him I needed my car to work, he said "that's your problem." I told him that I was told by the mechanic on Saturday that he fixed the problem and would have the car Monday. ***** told me that once my engine was "put back together" and ******* took it for a test drive, the check engine light went back on! I cannot believe that this dealership has had my car in and out of service since September 12, 2022 and still cannot diagnose and fix the issue! I asked the service manager ***** what parts my car needed now and he refused to tell me. In addition, I asked ***** for the information for the owner of the dealership which he also refused to give me. So now my 2018 car has been in service for weeks, with no end in sight, according to the service manager. I need help with the issue now please! Thank you!
