What Owners Actually Report

""Year 5 was rough. I hit the MCU failure and wasn't under warranty anymore. $2,200 out of pocket. If I'd had extended warranty I wouldn't have thought twice about it.""

Tesla Model 3 owner, forum report

""I almost didn't buy extended warranty because the car was running perfectly at 3 years. Six months after factory expiry the [major component] went. Lesson learned — buy before you need it.""

Tesla Model 3 owner

""The peace of mind alone is worth it for me. I can afford a $200 deductible. I cannot afford a $4,000 surprise repair.""
