Some other common problems reported by Highlander drivers

A failed ignition coil can sometimes cause an engine misfire or check engine light. This is more common on 

older Highlander SUVs from the early 2000s. Even if all of the coils do not fail at once, replacing all the ignition coils 

at once is a good idea. If not, you may end up back in the shop after not too long.

This Toyota Highlander problem was reported between 80,000 miles; one even had 2,100,000 miles before the 

issue popped up. Depending on where you get it fixed, this problem could run between $500 and $700.
