Got a letter from Honda Extending the warrantee on the start/stop system for 10 years unlimted miles. It covers the starter, electronics and valve adjustement. What on the start/stop system would warrant an valve adjustments?
Honda Start/Stop Warranty Extension
- Thread starter millerbl00
- Start date
If I had to venture a guess, the constant stop start cycles. I don't care how an engine is designed, frequently stopping and starting, as the stop start system does is not as good as leaving the engine running. Having said that, waiting for a train with 100 cars in tow might warrant shutting an engine off, a traffic light in a crowded city, with constantly stopping then creeping along, leave it running. Your battery/batteries, starting system, engine, etc. will thank you. Flame away..............
Yes, I disabled mine right away.
Honda.
2020 Ridgeline
That would be the brand, goober.Honda.
Interesting. Our '19 Odyssey has start/stop unfortunately but haven't gotten anything in mail about it. Can you post specifics?
I suspect that if the valve adjustment gets too far out of spec, start/stop function may be affected.
NOT the other way around.
NOT the other way around.
You got receipts?
By the way the OP is worded, it makes it sound like all the Hondas, regardless of which model. Maybe it’s just Ridgelines since you didn’t get one, but that would be odd since it would reason that their logic is identical across all models.
For what? Oil, filters and maintenance items? Sure.
No, I mean supporting evidence for your claims.
Its for certain years and models. I dont have the letter in front of me right now. I think 2019-2023 Ridgelines and Passports and Pilots ??
Hence, me asking what specific vehicle he has.
Common sense, reading up on it, knowing people servicing them, and people with a lot more knowledgeable than both of us telling me. That's enough evidence for me. Oh and a few people left stranded because of the system malfunctioning. IIRC @Trav was left stranded with his buddy in his buddy's stop/start vehicle. Receipts? I don't own a vehicle with it, and if I did it would be disabled as soon as I took title to the car. You've been around long enough it is better leaving an engine running than constantly turning it on and off. Yes even in this day and age.
Some Hondas (some? many?) require a valve adjustment at higher mileage anyway. Is it now included under warranty, due to it's new 10-year term?
I should do that too on my 17Accord for driver assist features; lesson learned, my transmission is in limping mode now but the corporate does not want to hear about it
no Honda for me anymore
How are they monitoring valve clearance?
(that's a serious question. It would be cool if they're actually doing that)
