While I will be the first to say that Tesla has room for improvement with their service overall, every car manufacturer has issues like this. Go on any forum and you will see horror stories about brand new BMWs, Fords, Chevys, etc. Bad engines, bad transmissions, electrical gremlins that can't be fixed, etc. It happens to every maker.Same Situation here. Just 3 days after delivery(early Sep at Dublin, CA), my 23Model Y LR has a dead battery with only 85 miles driven. Now it's been in the Service center for almost 2 weeks and a battery replacement is in process. I think their QC procedure is poor, given a number of similar issues posted across this forum recently. I definitely want them to buy back the car, or give me a new Y. Not sure if the battery replacement record will impact the resale value.
Give them a chance to fix the issue. If they can't after making several attempts, then invoke the lemon law.
