Creaking noise when there is reverse torque from the front motor

[kchau]

Has anyone experienced a creaking when:

• Happens when there is reverse torque from the front motor (in R, or initiating regenerative braking at 14mph and slower)
• Comes from behind the passenger side footwell, closer to the center.
• Does not happen after it rains, but comes back after a highway drive when it dries out
• Does not happen with regenerative braking disabled and slowing with brakes (service menu)
• Does not happen over bumps, or anything other than when there is reverse torque from the front motor.

So far it's not brakes, suspension, or door seals.

Already been to the service center for round one without success, tough to nail down with the weather changing towards fall.

Just dropped it off at the service center for round 2. This time the technician said he was able to hear it from the outside, Front Passenger Side Wheel Well. Getting closer!

About to go pick up the car. If it really is rotor residue, this is wild.

Nope. That wasn’t it. Car will be intaked at the service center for round 3.

Round 3 didn’t work. Left it for round 4. Likelihood of lemon-ing just became non zero.

Resolved. If your car is a very early 2023 Model, Fremont built, September-October-November build/delivery, this may come in handy for you one day. 585xxx VIN
