“I take my car for updates (Recall) and now i am being told that the head gasket is blown and damaged the injectors The powertrain might pay for the blown head gasket but not the injectors (which were damaged due to the head gasket blowing) no coolant but the car never ran hot. Honda is trying to stick to me to pay out almost $7000.00 which is wrong when it went to them for a recall”

“Car just started jerking and eventually stopped. I had it checked and was told the turbo was gone. Took it to Honda they said the head gaskets are blown. The car is 5 1/2 years old and it not one time ever ran hot. I’m not the only one with this issue. Honda needs to do something to fix this. Every car that goes to service has this issue something is definitely not right”

Should you keep driving it?

This page can't tell you that. 0 of 26 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
