Refer to the reply from official Uber channel, which I raised similar question like you. End of day, what you can do, you raised a complain to Uber with photo evidence, receipts and name of rider

yes, you read it right, name of rider to claim back your repair cost. The rider will get suspended.
Personally, I had not encounter the scenario you mentioned, but, this is definitely a risk, your scenario totally valid. My worst case scenario is that the rider drunk and puke in my car, or to be exact, open window and puke, which resulted me unable to continue the trip afterwards, need to send the car for car wash immediately, and I claim the car wash from the rider (mind you, it is a cash ride, so, when I want to compensation from rider, his friend was adamant do not want to pay, just want to pay the fare listed only) so, I write to Uber on this incident
please ensure you report it within 48 hours after the trip, else, Uber may not entertain your request, provide the photo evidence with receipt and Uber paid me via weekly payment. Of course, what upset me is that not only I cannot continue my drive for next passenger, i.e. time wasted, opportunity cost, Uber even ask me to confirm the rider name. I was WTF....how do you expect me to remember the rider name???
And, this is first part, as Uber is encourage driver to contact rider, for whatsover reason, be it confirmation on location, pick up, etc.....my advice DON'T EVER DO THAT!!!!! Once the rider had your contact details, anything also they will come harass or call you. And, this rider called me, harass me why I complain to Uber, resulted his account get suspended. Not once, but multiple times, which in first few time, I told him nicely, whatever issue, please settle it with Uber, we are just independent Uber driver, not Uber staff, if you unhappy with my action or whatsover, you can complain to Uber to get me suspended too (but so far, my account still active, rating average hovering between 4.7 and 4.8 for 800+ completed trip) until I gave him the final warning, I am going to report him to police if he continue to call me, only then he stop calling me.
So, to all Uber drivers out there, the risk is real, you have to consider all these when decide to drive Uber. Don't be mislead with good income, easy money, etc.....I do not refute that driving Uber is flexible, the incidents I encountered is rather exception than norm where I do also have few good share of good riders (but with increasing cash ride, which now on average 50-80% of my daily trip is on cash ride, these sort of incident may be more frequent).
End of day, to all Uber drivers, please stay safe, stay alert, trust your gut feel or instinct, if you feel something not right, better cancel the ride, lost few ringgit petrol and time, rather than risk your car and safety. These are the increased risk and rewards of more demand of being Uber drivers nowadays. End of day, Uber doesn't care, or care is how many trip you can complete, how much commission they will able to deduct from the fare. And, if you guys have time, plenty of people still coming to their PSC to register as new drivers (proof economy are bad

). Any lost drivers will be quickly replace with new one. My advice to all potential new drivers, sign up and drive all you want, but, if you intend to quit your job, decide to do it full time with hope making it big, making big, you are just dreaming. The income from Uber can cover your expenses, but, won't make you rich or easy life. It's all hardwork. Don't ever buy new car just for intention of driving Uber or Grab, else, you have extra commitment to headache.
