Six coil replacement. Five of the six are the same, one is different. When you have trouble, instead of replacing all six, buy one of the five and the different one - can't return parts.
Replace the odd one, then start replacing one at a time to see which is bad. Worked on mine, only had to buy two instead of all six.
Lots of expense at 100,000 miles. Oil drip by oil cooler (for automatics) is caused by the gasket, which hardens. About $20 for the gasket, tedious to replace.
Also it's cheaper to replace the rear trailing arms (causes sway at about 100K) than to replace the bushings.
It's been a good vehicle, but I won't buy another because of the expensive maintenance.
That is not maintenance. Those are repairs. Japanese vehicles are not what everybody thinks they are.
