What are the problems with the Fiat 500 TwinAir?

Oil leakage

A common issue with this car is oil leakage. Many users have reported having oil leakage. This is usually caused by a cracked or damaged timing cover. After being in use for several years, the timing cover can crack or wear out because of dirt, heat, or even grime. So, when it does crack, it reduces the tightness of the timing cover and may lead to oil flowing from the engine.

To fix this problem, you will have to replace the bad or damaged timing cover. 

Shaking when idle

Another common issue that Fiat 500 TwinAir users should be ready to deal with is the car shaking when idle. Besides, other people have reported their car stalling abruptly when driving and some have stated that the engine lurches forward.

Trouble starting

As expected, Fiat 500 TwinAir also comes with starting problems. The main cause of this problem is a weak battery. So, this is the first part that you should check as these cars feature weak batteries. If that’s the case, you will have to replace the weak battery with a quality and powerful one. The next step is to check the starter and alternator. If these parts are damaged, replace them.

Rapidly wearing suspension

Suspension problems are very rampant in compact city cars like the Fiat 500 TwinAir model. This is because the car’s strut mounts become worn out so quickly. So, to avoid having this issue, you should replace the front strut top mount bearing as recommended by the manufacturer.

Signs of worn-out strut mounts are unusual tire wear, instability at high speeds, leaking fluid on the exterior of struts, and tires bouncing excessively.  

Loss of power

Users of the Fiat 500 TwinAir model should also be ready to deal with the loss of power. This is a common problem with Fiat 500 models. However, in this particular model, the problem is normally caused by a wastegate with a damaged pin. Apart from having starting problems, this issue can also lead to poor fuel economy and lack of boost.

To fix this problem, the owner will have to replace the damaged or broken wastegate pin.

Electrical problems

Fit 500 is known to have electrical issues. Some of the electrical problems that you should expect to experience are warning messages on the dashboard, intermittent taillights and other exterior lightings, and many other electrical issues. To fix this issue, you will have to examine your car’s battery, fuse, alternator, and wiring.
