2006 Toyota Prius engine problems

Filed Apr 2, 2024 · Electrical, Engine · NC

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.

According to the toyota dealership where I have my car maintained, my 2006 prius is in need of a new motherboard. Apparently there was a recall on this prior to so many miles on the vehicle but I have missed this deadline as my car did not show these symptoms prior to the cutoff.. My prius when turned on does not turn on the dash board features so I have no idea how fast I am driving. Once I reach my destination I am unable to turn my car off. The power button does not respond, usually for several hours. In these cases I usually leave my car on in the parking lot where I am and return over the next several hours to check on it. It tends to turn off after taking the car for a long drive several hours later. This occurs about twice a month now.

I was driving on a highway 95 south, almost to delaware, at night in the rain, after 4 hours on the road, everything stopped working. I couldn't accelerate, I had no brakes, and eventually even my lights went out. The entire electrical system was out. I was in heavy traffic, and don't even know how I got off the highway, and to a gas station. The tow truck driver couldn't even jump the battery enough to get the car in neutral, and had a difficult time getting it up on the flatbed to tow it home. I couldn't even lock the doors. I had a new key made at the dealership on 10/17/19 and I was using that key for hours driving to ct and a couple of days later I was half way home when everything in the car stopped working. I was towed to my home in md because I needed to be able to unpack my car and computer before taking it to the dealership. When the second tow came the next day, I handed him the key by the front door, which was my old key, and he was able to get the car in neutral right away, and at the dealership the car worked just fine. The only difference was the new key. The technician found that "the immobilizer ecu has an intermittent open circuit failure, causing the key to be seen as unauthorized and stall the engine." from jim coleman toyota. Apparently there is a part of the computer system that shuts off all systems if it detects an "unauthorized" key--I.e. If it believes the car is being stolen. It seems to me that this is a very dangerous program in this car. I had been using that new key for several days, and had no problem, but for it to decide in the middle of the highway after hours on the road that the key was a fake, I could have been killed or I could have killed someone else. I would much prefer that my car be stollen than that someone might get killed but shutting off everything while it was on the road.
