Toyota Prius Prime

My 2023 Prius Prime cannot be charged normally in hot weather without triggering a thermal-protection fault on its high-voltage charging system. Avondale Toyota diagnosed it in writing: CODE P1CE996 CHARGER COOLING FAN REVOLUTION SENSOR COMPONENT INTERNAL FAILURE. THE ELECTRIC CHARGER ASSEMBLY HAS A INTERNAL OPEN CIRCUIT CAUSING IT TO BE INOP. RECOMMEND REPLACEMENT ADD PN# G9090-47061. Quote: $2,516.99 plus ~$200 diagnostic. The vehicle cannot verify its high-voltage charger's cooling fan is…

Pulling out of a parking stall, when put vehicle in drive, the engine revved up and accelerated - vehicle crashed, the brakes did not work- there was skid marks. Floor mats are factory OEM were installed properly. I did not hit the accelerator and I am in good health and mind. I have driving for over 30 years, never had and accident nor a ticket! - A county officer was at the seen and left me with vehicle that had to be towed away. The Vehicle is a total loss. I have insurance but felt that…

Brake actuator had been making noises and it finally stopped working on 7/14/26. Thankfully my car was and stopped and parked. The car has 137k miles on it, one owner and no explanation of what caused this. There were no accidents, abuse, or failure to maintenance.

Frequency when I start car makes a very loud , painful high pitch noise for anywhere from 5-15 seconds

The brake light, abs light, and traction control light is on. This was a known issue with Toyota Prius. They extended the warranty but failed to adequately notify user. I believe this is a serious safety issue and should be a recall as it affects the adequate stopping of a car, not just an extended warranty.

Unknown. There were a multitude of codes that appeared on the diagnostics causing problems with engine. The temperature, brake, tire sensor lights are all on. The cruise control is not working. White smoke emitting from tail pipe and engine. Main engine coolant leaking. Car overheating rapidly.

The traction control, abs, and emergency brake light came on. We checked and the code produced was C1391. There’s a humming noise every 10 or so seconds when idle. The humming noise is also present when braking. We did some research and this appears to be an issue with Toyota Prius. We called the dealership and were informed that this was not a known issue. Thank you.

My 2012 Toyota Prius is experiencing brake actuator pump failure, presenting diagnostic trouble codes C1253 (brake actuator pump motor stuck/locked) and C1256 (brake actuator pump motor overcurrent). These codes trigger ABS, brake, and VSC warning lights and disable ABS and stability control. Toyota previously acknowledged this exact defect under Customer Support Program ZJB, which covered 2010-2015 Prius vehicles for brake booster and brake booster pump assembly failures triggered by these…

I am filing a formal safety complaint regarding a catastrophic brake component failure on my 2013 Toyota Prius, occurring at less than 83,000 miles. The vehicle’s Brake Master Cylinder/Actuator Assembly has suffered an internal hydraulic pressure leak, causing the electric booster pump to run continuously to prevent a total loss of braking assist. This is a well-documented manufacturing defect that directly compromises passenger safety, drastically increases stopping distances, and threatens a…
