Took my 2018 Tesla 3 in for service because it was making a lot of noise. Problem was due to wheel bearings corroded.
How many miles do you have on your Model 3?
Wheel bearings to do bad, eventually, but usually between 150K-200K miles.
Assuming that you are nowhere near that mileage range, has the car been in any accidents? Flooding? Ever?
It's not impossible, but highly atypical for wheel bearings to wears off this early. Also, bearings do not normally corrode, but wear out due to lack of lubrications (oil dries with age, seals fail and dirt gets in, etc.). Bearings would not corrode unless the car has flooded (water reached above the axle / mid-point of the wheel).
Unfortunately, mechanic states they also found that the battery was cracked, likely due to a pothole. They said it would be so expensive to replace that we needed to file a claim with our insurance company. Mechanic said that we may not have even noticed that we went over the potholes as potholes can cause a lot of damage, even small ones.
There is something weird going on with your car, to say the least.
What exactly does it mean "battery was cracked"? Are you getting any error faults? If not, what cracked and did not short any circuits?
Are just talking about the under-tray?
That's way more likely, but it wouldn't cost much to repair.
Mechanic also claimed we took the vehicle off road. I baby the car and don't even drive it in the winter.
Anyone else have a similar problem?
No, this is a highly atypical situation.
I would either dig deeper myself, or take the car to another mechanic for a second opinion!
HTH,
