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 Questions

If the fuse doesn't work could it simply need a fuse? Where is the fuse box anyway?

I don't drive off road.

parking at an angle light was on. Would that be enough to discharge it? If not, is there anything else that could be draining the power. I think the battery is OK? It's been fine for years.

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.

Toyota Prius Reviews

Best car I ever had! Extremely reliable. First repair (other than scheduled maintenance) was at 150,000 miles when the rear wheel bearings were replaced. 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.

I purchased my Prius in 2008 with just under 5,000 on it. It now has 62,400 on it, so I've put just about 11,000 miles a year on it. I've had to replace one headlight, cost me over $300 to do it, excessive in my opinion. Why they designed it so that the bumper had to come off is beyond me, much less $180 just for the bulb. Had to replace the axillary battery about two months ago for a l...
