06-09 honda civics have a known manufactoring defect in the engine block. They mostly fail at the 90k mark a person driving 8k miles a year may not encounter this until the 12th year of ownership. The repair for this known defect is 2500-4500 depending on the dealer. Honda knows about the defect which is why the extended coverage to 10 years. But for owners who are just hitting this 90k-100k thresh hold we are out of luck and need to fork out almost half of a used car. I have loved and pampered my honda for the past 10 years. I don't think it is a question of if it will fail but when.
The paint started peeling after a few years. Recall notice not given until out of warranty. Had to pay $800 to repaint the hood and trunk. Every Honda Civic I've owned 1996 (224k trade-in), 2004 (190k died), 2006 (still running) had the passenger side window motor fail. However, the automatic transmission is good. Exhaust problem fixed by Honda but it failed again and was a few days over that warranty. On the 2004 Civic the transmission failed and had to be replaced by Honda after only 2k miles, so I'm sensitive about that. I'll try an Accord in a few years after I get to 250K or the car wears out.
I bought this car my senior year of high school and truly would go back and do it all over again. For my daily commute and how much i drove, the MPG and reliability were great! I get anywhere from 350 to 500 miles to the tank depending upon where i drive(city/highway) or how had on the pedal i am. I bought the car with 80,000 on the clock and now has 152,000 and have had zero issues other then regular/routine maintenance. I love this car and would recommend it to friends and family or for someone's first car! I am a pretty tall guy and was a little disappointed when i first saw the car but when i got in and realized how much room i had and how comfortable it was i was amazed.
Excellent car, I find it strange that you have a handful of complainers out of over 800 reviews. I don't even bother looking at those reviews when you have almost a 5 star score and just a few 1-2 stars.
