2019 Toyota Prius Prime problems

Filed Oct 7, 2026 · Electrical · CA

The center infotainment/navigation display on my 2019 Toyota Prius Prime repeatedly turns off and back on while driving. The screen goes blank and then restarts, including the map display. The vehicle itself continues to drive normally. The display is still in the vehicle and is available for inspection. This is a safety concern because the navigation screen goes blank while the vehicle is moving, which can distract the driver. Toyota has already documented this condition in Technical Service Bulletin T-SB-0031-20, which covers intermittent rebooting, screen flashing, and the screen going blank on 2017–2020 Prius Prime vehicles with the large Premium Audio display. On October 7, 2026, I took the vehicle to Toyota of San Bernardino and asked them to perform the multimedia software update under T-SB-0031-20. The dealer refused to do the update at no charge. The problem has not been repaired. The vehicle has not been inspected by the manufacturer, police, or an insurance representative. No warning lamps appeared before the screen started turning off and on. The screen simply goes blank and restarts while driving.

I was parked. I put my car in reverse. I heard the beeping sound confirming it was in reverse. I put my foot on the accelerator and the car went forward instead of reverse. This happened twice. I immediately shut off the car and turned it back on. Then it worked fine, and continued to work fine for the rest of the day as I drove to 7-8 more stops where I shut off the car. This was witnessed by a friend who confirmed that he heard the beeping sound for reverse, yet the car moved forward when I pushed on the gas. It definitely was not any kind of user error.

I've have to take my 2019 Prius Prime (with 20,000 miles total) in twice for brake issues in 6 weeks. Each time the dealer had to deal with a rotor heat issue. The first service was on 3/29/2021, the initial reason for appt was hearing squealing from the front. Upon inspection dealer found major heat marks and deep scratches/grooves as well as the rear rotors had deep scratches as well . All 4 rotors were resurfaced and the brake pads were “scuffed” during the service. At that time all brakes were inspected with the front brakes having 9mm and rears having 8mm of pads. I started hearing grinding a grinding sound about 2 week later. I took my car in for service on 5/11/2021 where the dealer found a “rusty” color on the rotors as well as a cracked and chipped front brake pad. They started a TAS case after which they resurfaced the rotors again and replaced the front brake pads. I am concerned about this issue with my car only having 20,000 miles on it and the rotors being resurfaced twice in less than 2,000 miles between services. The rotors and pads are supposed to be designed to have a longer life than standard gas non-hybrid vehicles. Rotors are only able to be resurfaced a limited number of times, which can cause future repair costs to soar. I am in need of Toyota’s assistance in making any fixes so this does not continue to occur. As well as looking into if there is a larger brake issue within my vehicle.

When I drive the vehicle on the freeway, it feels unstable. It goes left and right. The vehicle is brand new. We just bought it last week. Tire pressure is good and the dealership said there is no recall on the car.

Car had 27540 miles on factory original toyo nanoenergy tires when the rear passenger tire blew out. I was 22 miles into my drive home . No tps warning and I had visually looked at my tires before heading home. The entire tread separated from the sidewalls. The sidewalls stayed with the rim and I was able to safely stop the car on the grass median. This type of sidewall blowout has never happened in all my years of driving. I was on us-321 north bound just after the hardin rd exit going 70 MPH at time of blowout. Not in a turn but nearly straight line driving. Weather was mostly sunny and 65 degrees.
