While driving, airbag, (!), vsa, vtc and brake lights all lit up. Horn stopped working as did all controls from steering wheel (cruise, radio airbag light). I pulled over, everything seemed to work but lights would not turn off. Went to Honda in ft pierce, FL. Was told it's probably a low battery. Replaced battery, lights all stayed on. Contacted johnston Honda in stuart, FL. Head mechanic told me he had no idea what would cause this and if he ran it on diagnostics, it could take 8 hours at $80 an hour and he still may not find the problem. Brought this lemon to local mechanic who ran on diagnostics for 2 hours. Could not find problem so he did not charge. As almost all other complaints above, while driving at 35 to 40 the car starts to shudder as though it will turn off. Was told it's possibly defective motor mounts. I have contacted american Honda motor works in California with these issues and they essentially told me to 'gfy'. Stated car is not their problem.
