Earlier this morning, my daily driver turned 200K. I am the original owner.
Repairs: Headgasket failure at 185k
, MAF Sensor failure at 153K and an intermediate steering shaft (u-joint became "sloppy") at around 150K.
Maintenance: Oil Changes with every 10k from 0-90k, then every 5K. Most oil changes have been with 0w20 synthetic, some have been with 5w-30. No oil consumption so far. Air/Cabin Filters every 30K, transaxle has been serviced every 30K with ATF-WS. Brake Fluid flushed every 30-45K. Coolant (engine and inverter) was done at 30k, 92k, 122k, 180K and 185k. Thermostat was done at 122k and again when the HG was replaced. Both electric water pumps (engine and inverter) were replaced at 180K for maintenance. The EGR was cleaned at 180K as well but was not blocked. Front Lower Control Arms were replaced at around 97K with OE because the bushings became "squeaky" but were not cracked; the issue has recently surfaced again. Struts and Shocks have both been replaced twice with OE, but was probably not needed. Spark plugs were replaced at 92k, 180k and 185K. PCV valve was replaced at 180K. 12V Battery was replaced in 2015.
Hybrid Battery: Still original, but displaying some signs of weakness with A/C use. I have reconditioned it a few times with the Prolong system
but with only short-term improvements. Current cost on a new one is about $2500 from Toyota.
Fuel Economy: I stopped keeping track several years ago but it is usually in the low 40's with mixed driving.
Conclusion: It has been a great daily driver minus the head gasket issue. The car carries a lot of cargo (compared to a Corolla/Civic), delivers excellent fuel economy and is reasonably easy to work on.
