2021 Tesla Model Y Engine Problems

I am filing this complaint regarding a high-voltage battery defect in my 2021 Tesla Model Y. The vehicle has been diagnosed by Tesla Service, and both the technician and service advisor confirmed that the high-voltage battery has an internal short. This is a critical failure involving the primary energy/storage system of the vehicle. Despite acknowledging the internal failure, Tesla is denying warranty coverage for the battery replacement. They have stated that failure is internal, and is not caused by anything external The failure was not caused by an accident, environmental exposure, or improper use. This appears to be a component-level defect within the 2021 Tesla Model Y battery packs Considering Tesla has issued prior service bulletins for Model Y high-voltage battery quality issues in adjacent model years, this may indicate a broader pattern of battery defects. They are trying to charge people over $12,000 for battery replacements that should be covered by tesla due to poor workmanship and materials used. Many have had to have multiple battery packs replaced.

My son was driving my Model Y Performance Trim Tesla Model Y on May 23,, 2022 and thank god he was in a relatively safe parking lot; the vehicle had a loud thud noise coming from the rear and then it spontaneously died due to allegedly a rear motor failure (it's a dual motor Model Y). The Tesla then turned off essentially and locked itself in "Park" -- the vehicle could not be taken out of Park. Had to get it on a flatbed -- it now sits at the San Antonio, Texas Service Center off interstate 10 where allegedly it will be undergoing a diagnosis. But this rear motor failure (according to some of the indicator lights) is unbelievably dangerous inasmuch as the failure occurred without warning and without an opportunity to apply reasonable contingency protocols -- had this happened on a highway or street lane -- the complete unexpected stopping of the vehicle would assuredly be cause for grave damage and serious bodily injury or death.

The contact owns a 2021 Tesla Model Y. The contact stated that her husband was attempting to drive from a stationary position and depressing the accelerator pedal, the vehicle stalled. The contact stated that no warning light was illuminated. The contact experienced the failure three times. The contact took the vehicle to the local dealer; however, the mechanic was unable to duplicate the failure. The manufacturer had been informed of the failure. The failure mileage was unknown.
