The Toyota Yaris comes with a 1.5L 4-cylinder engine which should last well over 250,000 miles with regular oil changes and routine maintenance. There are even examples of people reaching over 500,000 miles on the original engine – they are incredibly well built.
If I buy the car I expect to keep it for at least 5 to 6 years. It will eventually be a hand me down for my son who will drive it when he turns 16. I've been told that typically age matters more than miles with these batteries and 10-13 years is expected life. Idk anything more concrete than that but I love my '15.
The 12V battery losing charge seems to have been relatively consistent. It is possible this could be a result of the HV cable issue attracting more attention/ being blamed for issues with the hybrid battery. It is also very possible that the hybrid battery and 12V battery inexplicably draining and the HV cable issue are problems that are linked
According to my BlueDriver diagnostic tool, the highest charge on the driver display, 8 out of 8 bars, is actually 80% of actual battery capacity. If you want to maximize the life of these batteries, you don't want to charge them to literally 100%. This 80% rule of thumb is endorsed by most EV makers, isn't something made up by Toyota.
As far as the battery, unless the battery gets a bad cell, you shouldn't need to replace it. Usually, that'll happen early on the cars life (so it'd be covered by warranty). Even if it loses a lot of capacity over 10 years, a PHEV will just spend more time in hybrid mode vs ev mode, so that's not a real concern.
The Secret The Dealers Do Not Want You To Know, Hybrid Battery Maintenance Here is the secret that every Toyota dealer will never tell you about your NiMH hybrid battery. It is 100% serviceable
If you want long term reliability, go with less complicated; I have a 2005 Civic EX with the 4 speed auto, the 1.7L engine in it is adequate, plenty of power for every day driving, and I still average in the high 30's with the automatic seeing as high as 40 on a long distance trip, I was able to get 500 miles to a tank of fuel.
Charge to 12.5v. Car worked like new. Few days later after not driving for 36 hours, checked battery, it’s down to 11.5v. Spoke with Toyota to query it and was told- Hybrid batteries are smaller than non hybrid, they run flat quicker, I need to take car for a “decent” drive every few days (30mins doing 80km or above) to keep charge.
Generally, when a hybrid battery fails, it's usually just a few cells in the battery that have failed. So rebuilders replace just those cells and recharge all the others up to spec. Some local electronics guys have started businesses rebuilding these batterys for around $1,000 to $1,500 while the dealers charge around $3,000 for a rebuilt battery.
