Power Train problem #1

In October 2024, I brought my recently purchased used Model S to the cincinnati service center for an antenna inspection, mcu upgrade, and general inspection to ensure the vehicle was safe and operating properly. During the inspection, I was informed that additional issues had been discovered. Wanting the vehicle to be reliable, I authorized the recommended repairs and ultimately paid more than $10,000 for the work performed. When I picked up the vehicle, a technician had to access it because the keys had been locked inside, and the battery had not been adequately charged. Shortly after leaving, I heard unusual noises and, within approximately five miles, discovered the protective underbody panel had not been properly secured and was hanging from the vehicle. Because I live in west virginia, I was unable to complete the trip home and required a tow to a charging station. During the drive, the vehicle displayed coolant-related warnings. When I contacted the service center, I was advised to continue driving the vehicle if it remained operable and return it when convenient. Only seven days later, the vehicle completely shut down and became inoperable. When I returned it to cincinnati, I was informed that the main battery required replacement at my expense despite previously being told multiple times that the battery was functioning properly. I have never received a clear explanation as to how the battery failed, why I am being held responsible, or whether the prior service contributed to the issue. Tesla instructed me to remove the vehicle from its property and return it to the seller. Although Tesla later offered $4,500 as a resolution, I declined because I do not believe I should be responsible for a battery failure that occurred immediately after extensive service work. I have photographs, invoices, service records, and additional documentation supporting my concerns.

Power Train problem #2

The drive unit has water damage from normal driving. The car never went through deep water or was flooded, but the tech at the service center is saying the units are sealed but still can get water in them and corrode. How can a vital sealed part of the vehicle be damaged by normal driving and claim water damage? the car operated just fine the day before. Please advise.
