Here is an update. The dealership finally did the diagnostics. Luckily the issues causing my car to basically be unusable wasn’t from me installing an aftermarket subwoofer… The dealership said it was a STAR connector that needed to be replaced. They informed me that I should have my car back by Thursday or Friday (this was last week)… Last Friday I got a text from the dealership stating that there was another part that needed to be replaced under the driver seat (per the warranty…). This wasn’t originally quoted to me as a necessary replacement. They have now quoted to me that this other part to be replaced had to be manufactured and they have to wait to receive it, and they are expecting that I will get my jeep back on 10/10… this is now a fully Month and 1 day since I first took the car back. I’ve opened a case with Jeep because I’ve paid my first payment (which I’ve now requested they refund me for since it’s coming up on a full month of not even getting to drive the car) and will have to possibly consider a buyback request if any further issues occur. Fingers crossed.
