The Most Common Hybrid Car Problems. If you’ve got a hybrid vehicle, it is likely that your repairs will be more expensive than those of regular vehicles. That’s because they have parts which are costlier and there aren’t as many technicians who have the necessary training to repair them. We are going to show you some of the most common hybrid car problems which may occur. However, you must remember that regular maintenance of your vehicle can actually help you to avoid some of these problems in the first place. When you see your “check engine” light appear, you need to be aware of the possible problems it signifies, like the following: A faulty oxygen sensor can cause the car’s gas mileage to drop because of the wrong information which is being sent to the care. Remember, the oxygen sensor tells the car’s computer how much fuel is in the tank, because it measures the amount of unburned oxygen in the exhaust.. A loose/missing gas cap can cause the gas to evaporate from the car, thus lessening the gas mileage. If your gas cap is loose, you can get it tightened for free and if your gas cap is missing, you can have it replaced for a small payment.. A broken catalytic converter can cause problems for your car to use a catalyst to convert harmful gases left over from combustion into emissions that are not as harmful. This can be quite a bit more expensive to repair.. A malfunctioning mass air flow sensor can cause a result in the car losing power, a decrease in fuel economy, as well as surges during acceleration. You should get this fixed as soon as you can, because you need this to measure the amount of air supplied to the engine, which in turn decides how much fuel you should deliver to the engine.. A set of misfiring spark plug can cause damage to your catalytic converter, as well as affect your fuel economy and engine power. Repairing these parts help the car get going, by igniting the fuel which is compressed the internal combustion engine.
