Does this make sense to anyone? We were driving the other day and suddenly started hearing a large rattling/clanking noise. We took the car into the dealer the next day. They said the right front subframe bolt became completely dislodged, which as a result caused the right front halfshaft boot to become torn. They put the bolt back in, but to fix the halfshaft (no idea what that is) will cost $800. The dealership said we "must" have hit something or gone offroading to cause the bolt to unscrew itself, so they are refusing to cover it under warranty. We never hit anything, and my wife definitely does not go offroading in between shuttling the kids to basketball and tennis practice. And there is no physical evidence of any damage to the car whatsoever. It is an April 2020 Long Range Plus with 20k miles, so still pretty new. Any advice as to whether what Tesla is saying makes sense and how to approach this?
Below is what they wrote up in my invoice/estimate:
Concern: Rattle or squeak - customer states: Loud rattling from under car when driving - Customer stopped by service center 11/15/21, confirmed noise/vibration, technician inspected and found the Right Front Subframe Bolt dislodged from impact to Right Front Halfshaft which resulted in the Right Front Halfshaft boot to be torn, secured and torqued all suspension bolts to specifications, recommend replacement of Right Front Halfshaft
