My coworker owns a 2008 and has had many more issues, some of which appear to be common. Vehicle drives great and currently has 120000kms. He is glad that he has extended warranty:
1. Timing Belt tensioner has died twice. Thankfully it was audible before total catastrophic failure. Apparently, it is very common.
2. Steering gearbox had to be replaced twice.
3. Engine rear main seal had to be replaced because it was leaking.
4. Leaky fuel injectors. The symptom was the car needed a little extra crank sometimes. In doing so, it made a very weird noise.
5. Front wheel bearings. Apparently very common for them to fail at low mileage.
6. If you have the battery replaced at the dealer, be careful. Honda/Acura OEM batteries seem to be prone to intermittent cells. The symptom is you're driving along and the car suddenly stumbles, or quits (no power on dash or engine). Contrary to popular belief and even what the techs will tell you, the alternator will not pick up the load. Why? The alternator generates fairly noisy, dirty power with voltage spikes. The battery, being a capacitor acts like a low pass filter and regulates the power. When the battery quits, the alternator puts out spikes. This can damage the electronics. Most manufacturers have put safeties in their electronics that will shutdown when this condition occurs. The techs could not diagnose this and I had to tell my buddy to fork out some cash, put in a battery and prove it to them. He did. Needless to say, they reimbursed him.
7. Lot's of little squeaks and rattles since almost brand new. Very annoying in vehicle of this price point.
8. Seal on rear diff had to be replaced because it was leaking.
9. Rear shocks gave out around 80-90k kms. Expensive because they are the adaptive ones.
All this in 5 years of ownership and 120000kms.
I can tell you my Mazda is more reliable despite being a rust bucket in almost 10 years and 325000kms of ownership.
