Not sure if this has happened to anyone else, but about 1/2 of the front underbody aero cover came off my car while driving home on the highway today. Thankfully, it did not hit anyone behind me or cause any accidents. I haven't scrapped the underbody on anything, but what's left is waterlogged, likely from the recent rain/sleet/snow and water on the roads from snow melt. It's part #4 in the parts diagram below. With any luck the service center gets the part prior to my appt.

I don't know yet, but I'm guessing I'll end up having to pay. My appt is next Friday I'll post afterwards.

I had a similar experience with the mid aero shield, behind the battery. The leading edge of the shield started to separate from the vehicle and was hanging down. Visited the Lawrence SC on Jan 25th and they temporarily secured it using some zip ties, and ordered a new one. Part hasn't come in yet and in the mean time, a chuck of it started to fall off and I had to tear the piece off. Still waiting for the part, but they've said it will be warranty.

Was back at Lawrence March 1, due to a clunking noise in the front end when going over bumpy roads. Turned out to be an accumulation of snow and ice on top of the front aero shield. They gave me a rental for the day at no charge and cleaned out the snow and ice. No charge for the service.

I just found myself musing about various things: 1) removing these fairings for winter, 2) adding a layer of fiberglass to them, 3) making a version out of aluminum sheet, 4) adding baffles to decrease ingress of snow and sand, 5) adding holes and slots to improve drainage and shed sand, 6) encouraging the SEC to sentence Musk to three months in Buffalo.

You're coming up on two months since your SC visit. Good to hear they are going to cover it. Any expectation set on when they expect the part?

I asked when I was in for another issue March 1st (snow and ice in top of the front aero shield) and they didn't have an answer as to delivery. I plan on following up this week.

Appt was Friday. I arrived 15 min early and they were ready, taking the car in immediately and indicating they had the parts on hand. No damage underneath, but it does look like something did hit the cover due to scrape on what remains. New cover was put in place and they did a tech bulletin service on frunk latch. Cover not covered under warranty and cost a bit over $300 to replace. No argument from me given the scrape. Very pleased they had everything in stock and the repair was done quickly while I waited (about 40min total).

Thank you all for posting about this issue here and other forums. It really educated me when the same thing happened to me and it got me angry. My Mid Aero Shield was damaged last week in the rain. I was shocked to find out Telsa was not covering it under warranty, especially with the TSB # SB-19-12-001 that was issued earlier this year. My Model 3 is 2 months old and I live in Miami where it rains, hard, all summer. After reading all the damaged aero shield posts on this forum and others, I'm more annoyed. I wrote Tesla and I'm attempting to invoked arbitration on this issue. I have also complained to the NHSTA, DOT, Florida AG's Office, the CFPB and the Better Business Bureau. Its really not about the $214 it cost to replace the shield. Its about a clearly defective part that should be recalled and replaced. The service guy at the Tesla Coral Gables service center said the Tesla mid aero shield, part # 1104313-00-B, is the number 1 stocked item at their service center. Yes, I had the new aero shield required by the TSB and it still failed. I paid $60k for a car i cant drive in the rain.

And now the service center says there are scratches under the front, so warranty won't cover, despite the tsb for replacement of the easily waterlogged defective shield. Let's see what they charge for this.

Yeah, I was lucky and got mine replaced under warranty, but another Houston member was not so lucky, even after showing them the bulletin.

TO me, this is a total copout on Tesla's behalf, especially when they say "if one breaks, replace both". That's admitting they have a problem. I've had similar TSB's in the past taken care of by BMW, Acura and Volvo. Tesla should definitely be taking care of this. It's a design defect. Not user negligence or a road hazard (at least not on my part, I drove through a freaking puddle).

I had the rear aero piece replaced this summer, now I've had a knock/rattle from the front for the last month, contacted service and they want me to drive 215 miles to replace suspension/steering parts. Snuck a peek underneath today and found a very ice aero piece hanging down.

A few weeks ago I installed a trailer hitch (Eco-Hitch) and noticed that all of the small 10mm bottom bolts holding the rear wind deflector were barley finger tight and one was missing entirely. If I had not removed and replaced the wind deflector, I suspect it wold have just been a matter of time before all the bolts loosened up and fell out.

I lucked out and the right rear trailing nut (circled in red above) had apparently pulled through so I cleaned the snow and ice off the top side of the cover, removed the nut and added a fender washer and screwed it back on. It's definitely good for now and I'll check it out in the spring. Assuming the rest of the cover is still good, I'll add a fender washer to the other side.
