2019 Toyota Prius Prime problems

“PASSENGER SIDE BEHIND THE DRIVER'S SEAT'S TIRE BLEW OUT. STARTED TO DRIVE AND CAR WAS MOVING SLOWER AND EVENTUALLY HAD TO PULL OVER BECAUSE CAR FELT UNSTABLE. WAS NOT GIVEN AN ALARM THAT THE TIRE WAS BLOWN AND FLAT. WAS DRIVING LESS THAN 30MPH, IN A STRAIGHT, FLAT STREET.”

“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'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…”

“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.”
