The most expensive proposition was a new windshield, but your particular insurance could solve that. Spark plug replacement was a surprise as far as cost is concerned. I've routinely changed the oil and cvt fluid once. No other maintenance issues. I love the car. Incredible roominess in the cabin and very capable offroad when needed.
2005 Camry 2.4L just changed original plugs at 130k miles. I go 5k on synthetic oil and don't have to add any between oil changes.
My 2015 outback has 140k miles. I just did spark plugs and belt, brakes. That's the only maintenance I've ever done other than tires and batteries.
Subaru forester. Mine is a 15. Comfortable, decent gas mileage, able to seat 4 with stuff in back. Kayaks fit on roof. AWD helps in rain and snow. Easy to do basic maintenance, but spark plugs SUCK.
The OEM plugs are iridium and are good for 120k miles, per Toyota. I paid about $16 per from a dealership (which I was happy to do, because its a job I dont want to be doing again in 50k miles).
Use the Toyota OEM iridium tip plugs. They are amazing!
Customer had misfires, bought oem spark plugs and coil pack. Customer came back couple months later, misfire came back. Found that port injector was bad.
Last thing on my agenda is the spark plugs. Got it with 131K and I’m pretty sure the previous owner literally sold it to avoid doing them. I know I should have done them yesterday, but god it looks like a bitch, even with Car Care Nut’s guide. I’m planning on doing the job with the new plenum gaskets, and ignition coils while I’m back there.
A regional tire store / repair center "recommend" spark plugs on my Sienna at 92K for $850 (intake manifold has to come off to get at 3 of the plugs). I asked them what benefit would there be in replacing spark plugs at 92K considering Toyota sets the spark plug replacement at 120K.
I now dread doing spark plugs. Something that’s super easy to do on most 4 cyl cars is a PITA doing on my ej25.
