Honda Civic Si Problem
Engine Affected: 1.6L 4 Cylinder
Visitor, 2008 Honda Civic Si, 75,000 mi
I have a 2008 honda civic si. One day the car took a minute to start up. It has never done that before. So I turned it off because the car felt sluggish upon trying to turn it on. I turned the car on again and there was a lot of vibration in the vehicle and it felt like the car was forcing itself to work. The vehicle was still operational but still not a good sign. The car then overheated on my way to school and my engine and VSA light came on. After getting enough coolant from a nice stranger, I took it to the nearest mechanic and they said two cylinders had a misfire but they also put a camera into the engine and saw a coolent leak. Upon further review, they saw that the head gasket had a crack and coolent had been getting into the engine for some time. The repair cost is $2200 which is ridiculous, especially since my car has less than 100k. My warranty expired February 2014 so Honda wont touch it. It puts me between a rock and a hard place so I felt I needed to file a complaint to hopefully have my car fixed. I understand the model years between 2006-2008 have had a lot of issues in the past and now I see that there can be a crack with the engine block on certain models. I also just received notice that the electrical steering had a recall as well. There are too many problems with this car so please help Honda.
