Rear of Y always dirty - why?

[Sandiegodoug]

Our x also gets really dirty back there.
Rest of car stays pretty clean

 

[Hunt3r]

Cause you drive on dirty roads.

Same thing happens to my wife's Volvo SUV

Agreed - my 2004 Z06 would get a lot of dirt at the bottom of the tail lights even on a short drive.
The Y has that small "shelf" at the bottom of rear diffuser which acts like a dustpan.

This. That shelf gets coated with dust with just a drive or two. Plus the sill right underneath the lip of the trunk gets filthy.

I PPF’d the rear and added two layers of ceramic coating. Maybe static makes it attract dust even more? Dunno. No real solution other than regular washing I guess.

Every car ever

I dunno. My BMW E93 never got this dirty in the back. It was the same level of dirt as the rest of the car which I’m happy to live with.

Your e90 had this problem?

 

[mswlogo]

Bet ya OP’s car is White. Get MSM next time, my S never looks that bad. My wife’s white car always looks like *sugar* in the back.

Yep

My Y came with front mud flaps but no rear mud flaps. I was wondering if I add the rear ones, would it help reduce the dirt on the rear side of the car? If anyone has seen improvement after installing the rear mudflaps, please share your experience. I think it will be very valuable to others.

Mud flaps will do virtually nothing for the thread topic dirty behind. It’s inherent with most all cars on the road.

I added front and rear mudflaps to our white model y. Level of dirt on rear hasn’t changed. I just wipe it off almost daily. Same with our model x.

Nope. Had em since new, still gets dirty back there.

My wife's BMW X5 does it, my 7 series did it. No car breaks the laws of physics.

Get some mud flaps.

I got mud flaps. Maybe they help. The MY's butt is still always dirty though. My other car, LX350, is not that bad

I agree with the OP that it seems extreme with the Model Y. No other car I’ve ever owned got so dirty on the back that quickly.

Even if I wipe the back completely dry with a microfiber towel- 5 miles later it’s completely coated in dust and dirt again.

It’s definitely in your face dirty if you have white as well. Run your finger on it and you can start drawing after just 5-10 miles.

wait until we're 100% EV, no more gas particles..

Unless you vacuum ALL the road surface right before you actually drive on it, your rear end will get dusty/dirty. You simply cannot "undo" physics.

Time to design for a “Tesla diaper”!!!!

 

[snovvman]

spoilers may help, but nothing will eliminate the issue for a vehicle shape prone to it.

Does the MYP's spoiler "help", even if a little. Do MYP's backside stay cleaner than MYLR? As someone mentioned, I wonder if a diffuser will help, too. Thanks.
