Toyota Prius Problems

The Check Engine Light may illuminate with a fault code P1121 stored. It is commonly caused by a failed three way coolant control valve. Valve replacement is recommended if this occurs.

The center multi-function display may failure. This is commonly caused by poorly soldered internal connection. Our technicians tell us that these display panels can be successfully repaired or reconditioned by a shop specializing in such repairs.

The fuel gauge may read incorrectly. Our technicians tell us there is a recalibration procedure which should be performed to correct this issue.

Toyota Prius Recalls

These vehicles are being recalled because one of the electronic components of the hybrid control system, the Intelligent Power Module (IPM), can fail internally. This module is located inside of the inverter module and contains transistors that may become damaged from high operating temperatures. If a failure were to occur, various warning lights would illuminate and the vehicle would only operate in a reduced power mode for a short time or stall completely, increasing the risk of a crash. Dealers will update the software in both the motor/generator control module and the hybrid control module to correct this concern. If an inverter module were to fail before the software updates are performed, it would be replaced as part of this recall.

The brake booster pump contains a compartment filled with nitrogen gas. This nitrogen gas can leak into the brake fluid causing reduced hydraulic pressure during application of the brakes. Reduced braking efficiency can increase the risk of a crash. Dealers will replace the brake booster pump assembly as necessary to correct this concern.

Vehicles have a tire size/weight rating label to inform owners of the carrying capacity of their vehicle. These models are being recalled because the incorrect vehicle weight rating is shown on the information label. This could result in vehicle and tire overloading, increasing the risk of tire failure. Owners will be provided an updated vehicle weight label to correct this concern.

The car now has 180,000 miles and still drives like new (no squeaks or rattles, tight steering and suspension) and still gets 42-46 MPG. I will buy another Prius in a heart beat but this one still runs so good that I just can't part with it.

Love my car, would have bought even if not a hybrid. Well designed inside & out, w/ a lot of features for a car in this price range.

The way I use this car is not ideal for a hybrid. I usually drive over 70 and its mostly all highway miles. I get about 41 mpg. I love pretty much everything about this car. It feels big and luxurious inside. It is like having a car that is trained to sense you - you never have to insert any keys and it reminds you if you leave your lights on and it doesn't let me lock my keys in the car. It i...
