03 4Runner 286K only been serviced twice but I take great care of it. Catalytic converters went out causing miss fires has been my biggest problem.
The 2AZ-FE 4 cylinder comes to mind. It came with defective rings and pistons that make it prone to burning too much oil. This in turn also makes it have an early failure of the catalytic converter due to the oil clogging it.
I replaced the cats at 190k at 225k I replaced all 4 brake calipers it didn’t need the rears but since I was doing the front I did them all and replaced the rear axle seals at the same time.
I have a 2003 Camry with 220k miles on it. My front cat was throwing a P0420 code (what the hell has it been smoking??) for the better part of the year and I finally changed it last month because my emissions inspection was due.
It cost me about $975 installed, but the most shocking thing to me was that my overall gas mileage went from 25 to 30.
