Toyota Prius is a great car and there is no doubt about it. But nothing is perfect. Here is a list of bugs and issues found in this car. I guess this list will be periodically updated by other people.

1. The US version of this car can switch between Miles and Kilometers, but the thermometer showing the internal and external temperature always shows the Fahrenheit degrees. It was confirmed first by Toyota Japan, second by Toyota USA and finally by my local dealership. It's not critical for everyone, but I honestly would prefer it to be in Celsius, it's just me personal preference.

2. The manual tells, that the buzzer-reminder about seat belts going ON when the speed exceeds 12 miles/hour can turned off by the dealership. They usually refuse to do that. It's like you buy the pair of pants with a built-in pampers. Safe and convenient! But will you be happy with this purchase? There are many sites on the Internet describing how to turn this "feature" off. Unfortunately, it doesn't work in Prius 2013 or I was so unlucky.

3. The player that came with enTune is more or less acceptable, although the settings could be way more advanced, but it basically works, except just one nuisance. You cannot browse your own files. Say, you grabbed your favorite music in a folder and want to find and play this folder. Forget about that. The player indexes all the files once you connected the USB drive, and then shows the different categories - in other words everything, but what you wanted.

4. The same player hangs up if you added the files to your USB drive with the names other than European code system. So if the names are using the upper 127 characters of the byte it will either show you the spaces instead of the file name and content, or quietly hang up. Nice feature! It's not final and once the incorrect files with the "bad" names are removed the player will return back and will re-index your USB drive.

5. Toyota Security system is the best. At least it was said multiple times by my dealership. Is it so? Well, actually it's a big disappointment, or rather a number of disappointments. If you turn the auto arming mode ON, then you will get a big surprise when you arrive to your garage, go take your mail, return back to the car and open it. It's not locked as it should be, according to the manual, the auto arming mode should do that. But it doesn't. It just activates itself. So don't trust the manual. If you forgot to lock your car it will never be locked. The alarm mode will be activated and the alarm will be turned ON... after 30 seconds, but the car will remain unlocked. These 30 seconds are enough to take your valuable things out of your car and quietly leave. Very impressive feature! The question is who designed it - a second grader?

6. If you finally found, that you should not trust the auto alarm mode and locked your car that's probably fine. You then return back, the car recognizes you, turns the light ON, lets you unlock the door if you just touch the handle since it feels the remote in your pocket. You then relax and go to the trunk or to the right door to load the car. It suddenly starts beeping because the alarm was not disarmed and it goes ON if you didn't disable it with your remote or didn't turn the engine ON - everything inside a 30 second delay, which can be changed only by your dealership.

7. If you finally decided to turn this cool feature off and open the ES3200 manual you finally realize, that you need to use the ignition key, but the problem is - the Prius doesn't have it. Be ready to drive back to your dealership and bend your knees and beg them to turn it off using their computer connected to ODB2. You will be lucky if they don't charge you $40-$60 or more dollars for this service.

8. If you upgraded your security system and installed the Glass Breakage sensor for $500+ be sure that it will keep silence even if the half of your car is disassembled. It's deaf and doesn't hear anything even set at the maximum sensitivity. The fact, that it's installed behind the plastic panel below your steering wheel means that the poor enough sensitivity will be even worse. Good luck with this super sensor! Really - it's just lost money, because the main security system is already preinstalled in the car and the sensor, being a very expensive addition, doesn't make yours and your car lives safer. The more advances Prius V has radar that could be used by the security system feeling all people cruising around. But not all Prius have these radars, that's for sure!

So there are only 8 complaints for now. I hope someone can add his problems to this list and make it longer. or even better - will add the possible ways to fix these issues. That would be great, because the Prius is a great car and I love it. But these nuisances are significantly lowering the entire impressions about the Toyota Company and this car in particular.

Unfortunately for the new owners of Prius, the latest 2013 models are still based on the 2010 models and inherit the same issues even if their software is up to date. Mine is 2013 and I got this issue when I reached 3700 miles. Both lights went ON and Prius stopped charging the battery while I was slowing down. The first impression - the break works, but not as eficiently as before. Plus the battery goes down pretty quickly because the only way to charge it is to drive and let the car charge it in background, which is not very powerful as you'd be charging while slowing down. The lights were ON for about 7-10 miles then the car automatically recovered with no explanation. The code didn't show any errors! The problem is - I drive in a very dry environment, the roads are close to perfect, but in this particular case I was standing in a parkig lot, the Prius was in the Parking position, but the engine was ON because I needed the AC. Suddenly both lights went ON. I did shut down right away and restarted the engine. It helped for a few seconds, then they both went back ON. Wow, seems pretty scary!
