Absolutely nothing. But then again, with only 3,500 KM's nothing should go wrong.
To start off I want to point out that I have not had this car long enough to make an opinion on the reliability. With only having it for 3 months and 3500 km's nothing should go wrong.
The impressions I have so far of this car is Honda has done one very good job. This car is seriously quick, comfortable and the digital dashboard is a nice added touch :). The handling is superb, transmission shifts nicely and driving at speeds upwards of 130 km/hr on the highway (about 85 mph) is very smooth.
My previous car was a 2005 Civic and I noticed some striking differences. First and foremost is the body shape. The 2005 looked like what it was, an econobox. This new Civic looks like a sportscar. The engine power is strikingly different as well. My 2005 had a 1.7 litre 115 horsepower engine that was rather gutless. This new Civic has the 1.8 Litre V-Tech, which makes 140 horsepower, and can you ever tell the difference. In terms of gas mileage the 2009 Civic also tends to get better mileage than my 2005 one did, but it is a very small increase.
All in all I have to say so far so good. Honda has nailed it once again. In a few months time I will provide another update as to how the car's reliability is.
Your 2005 model must have been miserable. I have a 1.8 VTEC and it is lame; there is no torque, I have been on faster push bikes.
I agree -- Honda is always very reliable.
