Our records show that you own, or previously owned, a Model S/X that was built before March 2018. It may be eligible for Tesla’s Warranty Adjustment Program covering malfunction of a memory chip (embedded MultiMediaCard). This malfunction may result in a blank or intermittently blank touchscreen but will not impact the ability to drive your car.
Tesla is providing eligible owners who experience a malfunction no-cost repairs to this part at any Tesla Service Center for 8 years/100k miles from initial delivery date. If you do not experience a malfunction, there’s no need to take action.
If you have already paid for repairs that meet the conditions of the program, you may be eligible for reimbursement. Tesla will send reimbursement details and eligibility by February 2021.
