While driving, the hood prop rod dislodged from its securing clip and fell onto the positive terminal of the battery. This caused an electrical short, which led to the rod heating up rapidly and igniting a fire under the hood. The fire damaged the headlight assembly and the surrounding trim panel, though the wiring fortunately did not catch fire. A nearby police officer was able to extinguish the fire before it spread further. This incident posed a serious safety risk and could have resulted in more extensive damage or injury. There were no warning lights or symptoms before the failure. The issue appears to stem from the design or failure of the clip that holds the hood prop rod in place. The vehicle has not been modified and was being driven under normal conditions. A local auto body shop inspected the vehicle afterward and confirmed that the loose prop rod made contact with the battery terminal, creating a serious fire hazard. They advised reporting this as a safety issue. The manufacturer has not yet inspected the vehicle. The incident was witnessed by a police officer, and the damage was evaluated by an independent repair shop following the fire.

The A/C relay switch has been replaced several times and now I'm having to replace the actual AC switch on the compressor due to it bogging my engine down every time I turn it on and it still won't blow cold air. This has been a continued issue and I've seen a lot of post online about it. So why hasn't it been recalled or something done about it.

My 2009 civic has a problem that has affected many other eighth generation civics: the A/C relay is faulty and is of a poor design and/or manufacture. The A/C relay is known to fail very prematurely and cause the compressor for the air conditioner to spin/cycle continuously or stay on (even when the A/C is not turned on), and thus cause the compressor to heat up tremendously and fail, which causes mechanical damage inside the cooling system. There are countless stories online, in car forums, and at honda dealerships and repair shops to back this assertion. Not only does this substandard A/C relay cause expensive damage that is not easily repaired (how does a 4 hour tear-down and reassembly sound?), but it represents a potential safety hazard since the relay is faulty and may cause issues not only with the rest of the electrical system (including the fuse box where it is located) but also because of the tremendous heat that a faulty relay generates when it causes the compressor to continuously cycle. The metal of the compressor actually changed color when it continuously cycled on my car, and is a telltale sign of this ever common failure. Honda is aware of this issue but has not seen fit to address it though tsbs/recalls for other models have been issued.

Tpms indicator is always on. Have taken to dealer to get service but they have said it's an electrical glitch cannot be fixed. This presents a safety issue if a real problem occurs not knowing when tires need adjustment.
