The IMA light coming on is usually caused by a battery pack that is no longer charging correctly. Replacing the battery pack will turn off the IMA light.
Honda Problem Reports
Most Reported Honda Problem Reports
On certain models the drivers seat bushings can wear out and the seat can rock back and forth. Replacing the bushings are needed to repair this issue.
The ABS modulator (hydraulic unit) can leak air into the brake system and cause a low brake pedal. A new ABS modulator will be needed if it is diagnosed to be the source of the leak.
A faulty brake master cylinder reservoir filter can cause the brake system indicator to illuminate after a cold start and then go off. Replacement of the reservoir filter will commonly fix this problem.
On automatic transmissions the accumulator cover can leak due to failed o-rings. Replacing the o-rings and cover will address this issue.
Worn door locks (tumblers) can cause the lock not to work. Removing the lock and replacing the worn parts (tumblers) is needed to get the lock working again.
Integrated Motor Assist (IMA) battery failures are not uncommon. The IMA battery will require replacement when it fails.
A knock or clunk type noise may be noted from the front suspension over bumps. This is can caused by worm stabilizer (sway) bar links. Replacing both stabilizer bar links will commonly repair this issue.
Plugged moon roof drains can cause a water leak inside the car, usually over the head of the driver or passengers head when turning a corner. Cleaning the drains will fix this problem.
The A/C fan speed control switch stopped working, had my local Honda shop repair it. The Resister pack that controls the fan speed burned out. Simple fix except that on my particular year/model Honda had a service bulletin that stated there was a problem with the AC Fan that caused this resister pack to fail thus requiring the fan AND resister pack be replaced together. I had this done and have had no problems since then.
The rear trailing arm bushings tend to crack and break requiring replacement of the bushings.
One or both of the rear sway bar end links may break resulting in a knocking noise from the rear of the vehicle.
The air cleaner case is prone to cracking. This can make it difficult to remove the screws securing the cover, making it difficult to replace the air filter. Replacing the case is often necessary to address this issue.
Impact to the front bumper can cause the connector on the washer pump to come off and the windshield washers will not work. Depending upon the severity of the impact it could damage the washer motor and bottle.
