Honda Civic 2006–2011: Common Problems and What to Check First
Covers 2006–2011 Honda Civic. Engines: 1.8L four-cylinder, 2.0L four-cylinder (Si).
The Civic has a reputation for reliability, and many of these cars run well past 200,000 miles. Two problems do come up often enough to be worth knowing about.
Coolant loss or overheating on early 1.8L engines
A cracked engine block has been widely reported on 1.8L Civics from the early part of this generation, causing coolant loss, overheating, or white smoke. It is more commonly reported on the earlier model years than the later ones.
What you might notice
- Coolant level dropping with no visible leak
- Temperature gauge climbing, or overheating
- White smoke from the exhaust or a sweet smell
What to check
- Check the coolant level when the engine is fully cold, and keep an eye on how fast it drops.
- Look for external leaks at the hoses and radiator first, since they are far more common.
- If it keeps losing coolant with no visible leak, have it pressure tested by a shop. Do not keep driving an overheating engine.
- Ask a Honda dealer whether any extended coverage applies to your car's engine.

Air conditioning that blows warm
A/C that stops cooling is a commonly reported complaint on this generation, with the compressor or condenser often named as the failed part. Low refrigerant from a leak is the simpler possibility to rule out first.
What you might notice
- Air that is warm or only slightly cool
- A rattle or grinding noise from the compressor when the A/C is on
- A/C that works and then stops
What to check
- Listen for the compressor clutch clicking on when you turn the A/C on.
- Look at the condenser in front of the radiator for damage, and check the compressor for noise.
- Have a shop check the refrigerant pressure and look for leaks before replacing parts.
