The Toyota Prius is one of the most popular vehicles in America, coming in 4th place in a TrueCar.com list. The Prius is also the top-selling Hybrid vehicle by far selling 6.1 million units globally. Toyota has always been known to design and manufacture excellent cars that are reliable and affordable, but they are not void of problems. Today, there is plenty of competition in the Hybrid sector of the car industry. However, despite this competition, nobody can compete with the MPG stats of the Toyota Prius. This is why the Prius represents a significant share of the Hybrid category.
No matter how well a car is designed and tested, there are still issues that arise — being a Toyota does not exclude the Prius from having problems. That said, here are the top 5 Toyota Prius issues:
5. Stalling or Loss of Power
There are reports mentioning that some Priuses are experiencing stalling or loss of power because of debris found in the mass air flow sensor. This happens when the air filter is changed carelessly, allowing debris to enter. Care must be taken when changing the air filter.
4. Failed Power Inverter Coolant Pump
This problem is causing the Check Engine light to come on. It is occurring because of the power inverter coolant pump is failing. If you have a scanning tool to check why you have the Check Engine light on and see code P0A93, the power inverter coolant pump is the problem. Unfortunately, the pump will need to be replaced. This is affecting models from 2004-2009 but has also been reported for 2014 models.
3. Check Engine Light with Code P1121
The Check Engine light could be on for a number of reasons. That’s why it’s great to have a scanning tool that could help solve the mystery. In this case, code P1121 refers to a faulty three-way coolant valve. The valve will need to be replaced immediately. This issue is affecting 2004-2011 models, yet still might affect newer models.
2. Fuel Gauge Reading Incorrectly
People buy Hybrids to save on fuel. Being that fuel is such an important theme for buyers of the Prius, one would expect the fuel gauge to be out of this world. Toyota knows about this issue and has released a service bulletin. The issue is affecting old and newer models. Nonetheless, fixing the problem is simple, so make sure to pass by your trusted Toyota repair shop to get it fixed.
1. Central Multi-Function Display Fails
This problem is also affecting older and newer models, whereby the main multi-function display does not turn on. The failure is caused by a poorly soldered connection and can be fixed by a repair shop that can do that.
The above by no means insinuates that Toyota Prius’ are not reliable. On the contrary, the reported issues were very minimal on a grand scale. These issues are meant as a guide in the case that you are experiencing such problems.
