Short answer

The hydraulic braking leads the 2010 Toyota Prius record at 27%, with braking system close behind. Of the hydraulic braking reports that give a mileage, half came before 3,000 miles. The costliest part on our cost list is the low beam bulb, $3.16 to $21 for the part alone.

It's a count of reports, not a failure rate. Use it to decide what to inspect before buying, not to grade the car.

What we know beyond the file

Toyota recalled 2010 Priuses in February 2010 to update the antilock brake software, after owners reported brakes that seemed to let go over bumps. Most early brake complaints describe that.

My 2010 prius v has very jerky brakes sometimes when starting out. Causes all people in car to be jerked around. Many other prius 2010 owners report same problem. Toyota denies knowing about problem in spite of many complaints!

2010 Toyota prius, 4500 miles while braking, the car hit a set of flush railroad tracks. The bump of the tracks caused the braking system to feel like it stopped working, and I had to re-pump the brakes to get braking to re-engage. The car has had a couple more similar episodes of the brakes seeming to dis-engage.

Abs light came on. Diag code: c1391. Abnormal leak in accumulator. This problem is similar to a recall on prius 2010 for abs brake issue. However, Toyota said that my prius is not part of the recall.

I repeatedly must replace my low head-beam lights in my 2010 prius. They have been going out at a rate of 2-4 times a year. I buy mid to high range quality bulbs and are very careful to keep the bulbs clean during installation. I notice there are many people with similar issues. How can we get this escalated to Toyota!

Was going 25 mph yesterday november 22, 2020 evening when 4 (brake, abs, traction & caution) lights came on dashboard. Pulled over the shoulder & turned ignition off. Restarted later & 4 lights still on. Following day, went to dealership & was told brake booster assembly need to be replaced due to internal fluid leak.

Is anyone looking into the headlight problem with the 2010 prius model v. I made a complaint to Toyota and nothing resulted. The low beams only extend about 40 feet, so that you can only safely travel about 30 mph with low beams or outrun your vision. There is a "curtain" effect. Obviously, one has to travel faster than 30 mph.

Low beam headlights on prius 2010 are very dim particularly for driving on dark country roads and they only project out a short way especially when going up a hill took to dealer who said they were ajusted correctly seems like a safety hazard high beam headlights are fine
