Love the car. Have no regrets buying the car...but
...on the Honda Clarity, the MM is utter BS when it comes to oil change intervals. Even if you assume 50-50 split on EV vs ICE...oil change interval should be at a minimum 15,000 miles or one year...period. Car companies and their dealer network have earned the reputation that they have...hardly qualifies as cynicism.
Of course a person can take any car under warranty to any mechanic they choose...or do it yourself. Keep all receipts and detailed documentation on all work performed. Its on you to ensure a qualified mechanic does the work or you do it correctly if DIY.
I despise the way these car companies use tactics to install doubt and fear about warranty coverage if you don't use their dealership network for maintenance. The dealers are not going to do anything about this except follow what Honda says via MM. Most often the dealers are either stupid or they play stupid and act like they don't know or understand squat. In the meantime, you are shelling out good money for totally unnecessary oil changes plus what ever else they can sell you.
Honda branded oil and oil filters are decent, run of the mill parts. If a person uses Honda OEM filter/oil OR or a name brand, extended life oil filter and a name brand 0w-20 full synthetic oil that meets API standards...either will meet or exceed Honda specs...and be able to perform more than adequately for 15k (7500 on ICE assuming 50-50 split) or one year.
I understand there will be exceptions due to conditions etc and thats all well and good. Folks just have to understand the environment they drive in and decide if MM is reasonable or not. Majority of folks I would wager are being taken for a ride on oil change intervals.
Folks need to stand up to this blatant and calculated effort by Honda to placate the dealership network and that is all this is. The software in the Clarity for MM is not an oversight or an oops...it is a well thought out process.
Love the car. Have no regrets buying the car...but...dealing with Honda is no different then dealing with Toyota or Subaru or Ford...they're all the same.
