After about 75,000 miles on my 2005 Honda Civic, I began to notice I got a headache and upset stomach while driving the car. The local Honda dealer discovered a cracked exhaust manifold, and indicated the possibility of carbon monoxide entering the cabin during vehicle operation. I have not yet repaired the condition since the repair cost is very high, about $1000. I have since heard that this is a common problem with this vehicle, and not a result of age or abuse.
