Toyota Prius V

N/a

My Prius had brake warning lights come on around December 2025. Turns out the brake accumulator had an internal leak. After doing some research, I discovered this was a known brake booster issue that Toyota has not issued a recall on. They do have an extended warranty program, but my vehicle did not qualify. The warning lights did not come on until after the 10 years or 150k miles cutoff for the warranty. Toyota's refusal to issue a recall and limits of their warranty program are clearly a move…

I purchased a 2014 Toyota Prius V in 2013, and it currently has 120,000 miles on it. Last month, the engine light came on, so I took it to a dealership. They diagnosed the issue and provided the codes P0302 and P0304. After consulting multiple shops, all confirmed that coolant is leaking into the engine, which means I either need to repair the head gasket or replace the engine entirely. The quotes I've received for this repair range from $5,000 to $15,000, while the current value of the car is…

Driving down the highway, the engine suddenly threw a rod, causing a terrible jolt, after which the engine burst into flames. There had been no warning lights.

The ABS system has failed. All brake related warning lights have appeared on the dash board and the ABS no longer works. The car will brake for now, but the pedal is mushy. The issue was diagnosed by a dealer. The diagnosis from the dealer, based on diagnostic trouble codes they did not provide, is that brake fluid is leaking in the master cylinder and brake booster. The recommendation is to have both the master cylinder and booster replaced. This vehicle has 143,000 miles on it. No accidents…

ABS, brake, and traction control lights, all illuminated at once on the dashboard. Inspection found DTC C1391 indicating the accumulator is leaking or failing to hold pressure correctly. We are advised that the braking system performance will decline, eventually failing. An very expensive repair is required and Toyota apparently has a shortage of the parts required. We cannot drive the vehicle given the potential of braking failure and cannot get it repaired in a timely manner for lack of…
