I have 195,000+ on my 2018 Clarity. I think it is a January 2018 build date.
I hit a deer in January, and the insurance company totaled it. I never took it off the road, so I bought it out from the insurance company, installed a new headlight, and kept it driving it. Then I hit a bear in August, and lost part of the left front fender, but I still drive it.
I have the leaking AC condenser. I had a bad front wheel bearing at 80K miles. One front brake rotor went bad (pad ground down to metal), probably because of uneven rust.
For maintenance, I have been changing the oil as per the maintenance minder, and rotate the tires. I have not replaced the brake fluid, or any other additional maintenance recommended. I bought spark plugs from Rock Auto, and will probably get them installed someday.
I use the heater in the winter, so I only get about 25 miles on EV, but I only got 28 miles EV when it was new in the winter. I am in upstate New York, so temperatures are regularly below 32F. This year, I installed 4 snow tires, so that would affect EV miles. I have been meaning to check battery capacity again, but I think I am still within 15-20% of new, and work has been busy. (The messed up front end has to really affect the aerodynamics, also.)
The insurance company only valued the car at $12,000 with 120,000 miles. If I could get another Clarity for that price, I would be very tempted to buy it. (Scrap value of the car was $5,000.)
