Hello, my 2015 prius is up for its 140k maintenance, but given the online research and talking to dealership and various maintenance shops. Also alot of the posts here suggest additional maintenance and precautionary steps that are not part of the manual specification. I accumulated a list of recs based on mileage from different sources, yet this doesn help and I feel lost Rec engine/cabin air filter dust build up Rec spark plugs Rec Hybrid battery fan service RecThrottle body /maf/efi services Rec Trans fluid service REc Collant Fluid Service Rec. Inverter fluid service low all that seems excessive and very costly, and i am writing this post to get a response from those who have been through it. Can someone please tell me what exactly toyota recommends according to their manual at 140k? no bells and whistles .
The Toyota USA maintenance schedule stops at 120k miles or 12 years. Due to the awkward, event-by-event format I made a table format equivalent (with MS Excel), which lets you see at a glance the frequency of the various items. Then I extrapolated it, to 240k miles or 24 years. Spoiler: 140k miles is purely a tire rotation. That's not to say that's all that should be done, but that's up to you, and dependent on what's been done, or missed, in past. Also, there are a few items Toyota USA says nothing about, but worth considering: EGR cleaning Transaxle fluid replacement Brake fluid replacement
thank you for this. I have saved the spread sheet to stay alter on what is needed. so spark plugs I never did, are they due at 140? also for your chart is this more precautionary or what you did to maintain your car based on your expereince or research?
sparks were due at 120k, so you should do them when you have a change. people often say they look new at 120.
Don't know how you missed spark plugs @ 120K Rec engine/cabin air filter dust build up - that should be changed around every 30K miles or visibility dirty or clogged. You should be able to do that yourself - dealership pricing for this service is outrageous. Rec spark plugs - should've been done @120k per OEM Rec Hybrid battery fan service - optional RecThrottle body /maf/efi services - optional; if your getting surging with a constant pedal - it needs to be cleaned. EFI is a bottle of Techcron (fuel injection cleaner) in your gas tank. Do that yourself. Rec Trans fluid service - optional, but you should get it done. IMHO it should be changed every 100K REc Coolant Service engine - should've been done @120K per OEM; footnotes states 50K mile change thereafter the initial change. Rec. Inverter coolant service - I believe that should be done @ 150K per OEM, most owners will change both at the same time - easier to track.
