Owners have filed 1,690 complaints
about the 2006 Toyota Prius with NHTSA between 2006 and 2026.
The largest single group is the lights.
Across this model's run it ranks 5 of 25 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 100
Against the median year of the Toyota Prius. 50 means typical for this
model; 100 means roughly double.
Severity — 52
10.1% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 43
25% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

NHTSA investigations into the 2006 Toyota Prius
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Recalls on the 2006 Toyota Prius
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous

STEERING
Toyota is recalling certain model year 2004-2009 Prius vehicles manufactured August 5, 2003, through March 30, 2009. The affected vehicles have a steering intermediate extension shaft assembly built with metal splines that complete the connection from the steering wheel to the steering gear. These splines may have been manufactured with an insufficient hardness.
Risk: Over time, the splines may wear and eventually fail resulting in a loss of steering ability, increasing the risk of a vehicle crash.
12V536000
ENGINE AND ENGINE COOLING
Toyota is recalling certain model year 2004-2009 Prius vehicles manufactured August 6, 2003, through March 30, 2009 and FCHV-adv vehicles manufactured December 12, 2008, through September 13, 2011. During manufacturing, a scratch may have occurred inside of the electrically driven water pump at the coil wire. The coil wire may corrode at the scratched portion.
Risk: The corroded coil wire may break and the water pump could stop. The corroded coil wire could cause a short circuit between coil wires and a possible open fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. This may increase the risk of a vehicle crash.

Recall 202172355,683 units in Canada
Electrical
Issue: This recall is for certain block heater kits installed on certain vehicles or sold as accessories at Toyota or Lexus dealerships. On certain vehicles, the engine block heater cable may not have enough heat protection and could be damaged by high temperatures. If this happens, the cable could short circuit while plugged in, and cause the wiring to overheat or melt. Note: This recall only affects the following block heater/cord part numbers: C014003034 PK5A408J09 PU14000904 C014003151 PK5A408J13 PU14000905 C014000885 PK5A489J11 PU14000907 C014000888 PK5A489J22 PU14000909 C014000907 PK5A410H00 PU14000911 C014100904 PU14000900 PU14000913 C014100907 PU14000901 PU14003571 C014100911 PU14000902 PK5A489J14 PK5A408J05 PU14000903 Safety Risk: Engine block heater wiring that overheats or melts could create the risk of a fire. Corrective Actions: Toyota recommends that you should stop using the engine block heater immediately. Toyota will notify owners by mail and instruct you to take your vehicle to a dealer to disable the engine block heater. For some vehicles, the corrective actions for this recall are under development. For others, a new engine block heater cannot be installed, and the owner will receive a refund of the purchase price of the engine block heater.
Recall 201238814,816 units in Canada
Steering
On certain vehicles, the steering intermediate shaft splines may have been improperly hardened. If the steering wheel is held firmly on the steering lock while turning sharply at low speeds, the splines could deform and wear, causing a backlash in the steering system. The splines could also become fully stripped, resulting in a potential loss of control causing a crash resulting in injury and/or damage to property. Correction: Dealers will inspect the vehicles and replace affected steering shafts.
Recall 20123878,740 units in Canada
Powertrain
On certain vehicles, the electrical water pump assembly, used to circulate coolant through the hybrid components, may fail. If this were to occur, coolant would stop circulating, illuminating various warning lights in the instrument panel of the vehicle. In certain cases, the water pump motor could short-circuit, causing the hybrid system to stop functioning and the engine to stall. A loss of propulsion, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing personal injury and/or property damage. Correction: Dealers will replace the electrical water pump.
Recall 2009290437,445 units in Canada
Other
On certain vehicles, the accelerator pedal may become stuck in the wide open position due to an unsecured or incompatible driver's floor mat. A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death. Correction: Dealers will reconfigure the shape of the accelerator pedal. Certain models will also have the shape of the floor underneath the accelerator pedal modified and/or a brake override system installed.
Recall 20061294,138 units in Canada
Steering
On certain vehicles, the connection at the intermediate shaft or the intermediate extension shaft may become loose or the intermediate shaft sleeve may develop a crack under certain operating conditions. The connection may separate or the shaft sleeve may fracture, which could result in the loss of steering control and an increased risk of a crash. Correction: Dealers will replace the steering intermediate shaft. In addition, the dealer will inspect the sliding yoke and the intermediate extension shaft and replace them if necessary.

I was involved in an auto accident on 4/20/2026 @ 6:23 PM. I was driving a 2006 Prius and the vehicle in front of me stopped to make a left turn. I applied my brakes, which grabbed slightly and then released. I then had to hit the brakes hard and they did the same thing again. I ended up rear-ending the vehicle in front of me and had to go to the hospital. I’ve been out of work since the accident, and I feel this was not my fault DUE TO FAULTY BRAKING SYSTEM ON THIS VEHICLE. My vehicle was declared a total loss, by the insurance company After doing my own research I have found many accidents with this type of vehicle that has had rear end accidents with injuries and some fatalities. it also shows not only this 2nd generation with this problem however the 3rd generation Prius as well. I have been out of work since the accident. I'm asking for a complete and thorough investigation into this and a satisfactory resolution to this so that it doesn't happen to anyone else. There were no warning indicators of any kind prior to the accident plus I had paid over 2000 dollars' worth of work and a set of 4 new tires put on this vehicle prior to this incident. Please advise and thank you.

I am looking to receive a little bit more assistance regarding my daughter's first car that she worked very hard for. It is a 2006 Toyota Prius. It was garage-kept and owned by an older couple who only put 85,000 miles on it. It is really a gem of a car. Soon after we registered the car, my daughter was out driving with her father. While going through a 4-way stop, she found that the brakes had failed and she was unable to stop at the intersection. Luckily, she was with her father, and he was able to give her verbal instruction to guide the both of them to safety. Upon further investigation, we learned that there was a recall on the Brake Actuator Assembly in 2016. Which is the part that has failed and almost caused my 16 year old daughter to crash the car she worked hard for. I contacted the Toyota Brand Engagement Center. It was stated to me that the recall has expired, however, I feel that the fact that a recall was issued means that it was recognized by Toyota that the vehicle was sold with a faulty brake system. This, in and of itself, is a hazard and could be fatal. This should be addressed and the brake system should be replaced as it is no fault to any owner regardless of the recall expiry date. We look forward to your timely response on how we can remedy this very serious safety issue. My daughter was super excited as she worked very hard to save up for her first Toyota and get it registered only to find that the brake system fails.

ELECTRICAL SYSTEM
The following describes a near total failure of the brake system that accompanies and is triggered by routine aging of the battery. I believe this applies to multiple model years and editions of the Prius, based on reports by other owners on owners' discussion groups. I believe this should have the highest severity level. Here is what happens: An alarm is sounded, several warning lights ABS, VCS appear, and soon after that, the front brakes stop working. The rear brakes then prove ineffective and lock up. The happens with high frequency under any of the following conditions: (a) as the battery approaches 3yrs age, (b) it is excessively cold outside. (c) there is a higher than typical load on the 12V system from any of a variety of reasons. After installing a fresh new 12V battery, the above happens with much less frequency. There no warning on the dashboard to indicate that the condition of the 12V battery is not safe for operation of the vehicle. It seems clear that the route cause is that the brake control unit is configured within inadequate tolerance for the normal aging of the 12V battery, compounded by the absence of warning on the dash. This probably traces back to a poorly chosen LDO voltage regulator in the design of the brake control unit. Recommendation: Review the electrical designs for the brake control unit, all model years, replace as needed and update the dash board computer to provide warning when the battery condition is not sufficient for safe operation of the vehicle. I further recommend that this be done with all due haste, as the condition is quite dangerous. Qualifications: PhD Chemical Physics and Electrical Engineer

VEHICLE SPEED CONTROL
The light up display for the odometer, fuel gauge, and speedometer does not always light up. When it is not lit, the cruise control and any warning and informative alarms/lights also do not work. This is a well-known issue among owners of these cars, related to the capacitors on the circuit board for the display being defective, and there is extensive documentation of it online. It may also have had a technical service bulletin released for the issue, but I'm not entirely sure. The light goes out intermittently and is not always consistently out. I did mention it to the service personnel when I took it in to get recalls repaired recently, and they didn't seem surprised or unaware of the issue. I did not ask them to diagnose or fix it, as I know I can get it done for a better deal elsewhere.

EXTERIOR LIGHTING
One afternoon, in the Summer of 23, I entered my Toyota Prius to run some errands. Once I proceeded to power on the car, none of the dashboard lights illuminated. This included the gas gauge, speedometer & transmission indicator. Fortunately, I was only driving a few blocks down the road from my residence as I live in a small rural town with little congestion, little traffic and mostly two-lane roads. I can't imagine this occurring in a much larger metropolitan city. When I arrived at my destination, I discovered that my Prius wouldn't shut off. This dashboard malfunction was preventing the Toyota from powering off. I quickly completed my errands with my vehicle running during this entire ordeal. Finally, when I returned home, I frantically researched on YouTube regarding this issue and discovered many others who also were having these no-illuminating-dashboard problems. Some YouTubers offered workarounds but the solutions will be temporary as the problem will eventually worsen until the Prius owners have no working dashboard lights. From the way I understand it, this problem is nothing more than a small computer board that's behind the speedometer and this computer board has a small diode that tends to burn out on all kinds of Toyota Priuses when it reaches around 150,000 miles.

I can't imagine this occurring in a much larger metropolitan city. When I arrived at my destination, I discovered that my Prius wouldn't shut off. This dashboard malfunction was preventing the Toyota from powering off. I quickly completed my errands with my vehicle running during this entire ordeal. Finally, when I returned home, I frantically researched on YouTube regarding this issue and discovered many others who also were having these no-illuminating-dashboard problems. Some YouTubers offered workarounds but the solutions will be temporary as the problem will eventually worsen until the Prius owners have no working dashboard lights. From the way I understand it, this problem is nothing more than a small computer board that's behind the speedometer and this computer board has a small diode that tends to burn out on all kinds of Toyota Priuses when it reaches around 150,000 miles.

One afternoon, in the Summer of 23, I entered my Toyota Prius to run some errands. Once I proceeded to power on the car, none of the dashboard lights illuminated. This included the gas gauge, speedometer & transmission indicator.

EXTERIOR LIGHTING
I was Driving down the main road at night time in my 2006 prius and the headlights both went out and all most caused a crash. I pulled over turned my car off then back on and the headlights came back on so i started driving home. After driving a couple blocks i was pulled over by the police because my drivers side headlight was off. Luckily he let me go with a warning, but i work at night and am losing money daily because of this problem. I sent toyota a email and no answer. There has been many electrical problems with this car and the speedometer still says i am deiving 34 to 35 mph while i am actually only going 30mph. I think that toyota should fully fix the problems in thos car. Its amazing there can be so much wrong with a vehicle and they not have to replace the vehicle with a vehicle that works or fix all the problems and give me a loaner vehicle. I will upload a picture of what the toyota dealership nearest to me wanted just to replace 1 bulb ans the balast wires going to the light for one loght they want $211.34 and that is just for the bulb and wire. For there time they said each bulb and wire would be around $500 worth of repair time to pay for them to put the new light and wire in so for one lightbulb with rhe wire would be about $800-$1000 for the dealership to replace the parts, so basically $2000 to replace both light bulbs and the wires and pay the toyota company to put them in. If you look at the estimate it is for 1 bulb and 1wire and that would be the price if i put them in and if i only wanted the parts. So $211.34 then i would have to double it because i would need 2 bulbs and 2 wires. Then i would have to add another $1000. That is $500 for labor for them to put the bulbs in per each bulb and wire and they said its not guaranteed it will fix the problem. So that is $422.68 for parts and they said somewere around $500 for them to install each bulb and wire and after it might not even fix the problem. So that is $2422.68 to maybe fix the problem.

Brake actuator is not working properly and will eventually get us in an accident. We bought the car brand new. There is a recall for this issue, but we were never notified by Toyota. After contacting Toyota, they claim we are out of the recall dates and will do nothing. I have requested a copy of the letter they should have sent you notifying us of this issue. They cannot provide one. I would like to be able to fix this car; I cannot afford another car or such an expensive repair caused by a defective Toyota part. Please, help us. Thank you.
