I use my 07 civic hybrid as a communter car to and from work. I average 35,000 miles per year and have had no problems. I do all the required maintanance ( most of it myself) and expect plenty of more miles to come. Intertior had held up strong with no issues whatsoever. All electronics work perfectly with no sign of impending failure. As for the IMA battery...I can tell it is going to go fairly soon. However, I do not plan on fixing it due to the nature of my driving. It will operate without an IMA battery, Just dont expect to get the accel youre used to. Overall, wish I would have purchased the non-hybrid version. But, I'll drive this one into the ground. Hoping that'll be a long time.
Everything but the IMA. Keep in mind, it's still a Honda.
Replace the batteries when they fail. It wont bankrupt your company, and it will regain the confidence in your customers.
