NHTSA Complaint #11560199 — 2015 CHRYSLER 200

One day without warning (about 8/20/2023), the vehicle would not start. After too many attempts the vehicle went into a security lock out. Had a mobile locksmith come and issue 2 new key fobs, and he was able to get the car unlocked and started. Car ran fine for about 4 days and then once again would not start. Car was towed to dealership where I was advised it was a bad battery. Battery was replaced 9/6/23. No issues for just over 1.5 months. Then, without any warning, all of the lights on the dashboard lit up on 10/30/23 (everything from the battery light, to the check engine, to even the "service parking break" alert). The car even lost power steering. Luckily, I had enough time to pull into a parking lot and get the car parked in a spot. The car then lost its ability to start. Car was then towed to same repair center where they then advised me it was a bad alternator, and everything wrong was because of a Non-OEM sound system placed in the car (this was installed in June of 2020 and has run with zero issues) - they stated the alternator needed to be replaced. No mention of a bad alternator was reported in the first inspection of the same issue. Alternator was then replaced at a different repair facility. Somewhere between the two facilities, the additional sound system was disconnected from power from the car and is no longer active. It is also important to note the system is hooked up to secondary battery, not the main battery in the front of car. In all, the car went back into the first repair facility from 10/30/23, was towed to the second on 11/6/23, and was finally returned 12/12/23. Even though it was at the first repair facility for a week, no repairs were done until it was towed to the second. However, today (12/14/23) just two days after getting the car back with NO Non-OEM sound system active, I am having the exact same issues for which I initially brought it to the first repair center. All of the lights on the dash went on and I lost power steering.
