Prius (2004-09) :: Intermittent Warning Message - The Transmission Lock Mechanism Is Abnormal
Jan 20, 2015
My 2005 Prius has about 140,000 miles. I had been getting the intermittent warning message, "Caution: The transmission lock mechanism is abnormal" although the vehicle has been able to start and drive just fine. I replaced the 12v battery, which was suggested in several other threads. However, the warning keeps reappearing. Possibly related, my gear shift knob is "sticky". I'm able to get it into each gear (and the transmission remains in the gear selected), but the knob does not move smoothly like it used to.

I own a 2005 prius that I purchased used this year. This morning I had my first issue. I turned on the car and it gave me the following error message:
"Transmission p lock mechanism is abnormal. Park your car in a flat place and apply parking brake completely."
The parking break wasn't on and I was already parked in a basically flat parking space. I couldn't move my car because it wouldn't go into drive or reverse or neutral. (The car turned on, but the engine wouldn't start). I tried turning the car off, but the car also wouldn't turn off. I let the car sit for 5 minutes then tried again and the car turned off. When it turned back on, everything was fine.
My questions is: Do I need to bring this into a mechanic? The car seems to work fine now, but I don't want to be stranded again or do damage to the car by driving it with an issue.

After trying to start my '08 Prius, the following message appears on my touch screen about 2-3 times a month: "The transmission PARK lock mechanism is abnormal. Park your car at a flat place and apply the parking brake completely". I try to patiently wait it out while I apply the parking brake, unapply it etc. Finally, all dash lights will go out, and I can then start the car.

A month or two ago I started getting the error message on my screen while driving. There is a problem with the Transmission P lock mechanism. Park you car on a flat surface and fully apply the parking brake. After reading up on the error, I replaced the 12-volt battery. (it was the original)

I've read around the forums stating the P Lock error is common from a low battery causing the vehicle not to start.
The strange thing is that my vehicle DOES start and the message appears and the dash shows READY and I am able to enter gear and drive. If I hit a button on the console the message goes away and if I'm driving at higher speeds the message does not return but the large triangle stays. The error message only reappears when I slow down to 3 mph.
The error does flash back on the screen when I slow down to stop or sit at a light. The car does not shut off during this it just flashes the message and shows the large triangle.
My battery test shows 12.3v on no load and 11.6 on a load. I would hate to replace my battery and have the issue not be resolved.

Weird problems with my 2006 prius. Car has 54,000 miles.
4 times now over the last year, during abnormal braking conditions (someone swerves over at me on highway and I have to break and swerve suddenly to avoid), I get multiple warning lights, and the warning buzzer. Yesterday this happened, and I got the red triangle, the red brake light, the abs light, and two new lights on the LCD display I've never seen before. I pulled over and began to slow down. The brakes felt stiff, and the vehicle started to loose acceleration power. LCD started resetting itself. I stopped the car, turned it off, and turned it back on to find everything normal. I then drove 200+ miles to my destination without incident.
This is the worst case of this problem yet. My 12v battery was replaced last year after the first of these issues, with similar symptoms, but no loss of acceleration. The tech said the only code in the system was a voltage spike, and thus thought it needed a new battery. In every other case of the problem, I turn the car off and turn it back on, and it's fine. I'm about to drive 2000 miles next week, and want to avoid further issues...

I'm getting an intermittent brake light warning message on my otherwise perfect '04 V8. It is the bulb in the center part of the 3rd brake light. To replace it I looked for access from inside or outside. No obvious way to get to it.

This has happened to me twice (just today and about a month ago). The first time I was just sitting in the car, turned it off. It was hot outside so I just hit the power button without my foot on the break to start up the air conditioner. After a few minutes, a message pops up on the screen saying something about the transmission couldn't put the car in park and to park it on a level surface. I was on a level surface. I tried to start the car and it wouldn't start. After several tries, including inserting the key fob in the slot it finally started.
Today, I had almost the same scenario, only I was just returning to the car. Four warning lights came on, the parking break light was on (even those it wasn't engaged), and again the transmission message came up, saying I should move the car to a flat surface. After fiddling around, I got the car started again and immediately went to the Toyota dealership. I was just there yesterday getting an oil change and a once over safely check before I head back north which is a total of 24 hours of driving over several days.

My 2011 Prius apparently had a broken lock actuator on the driver's door, and knowing that the dealer would charge me over $500 for installation of a new actuator, I decided to order a new $5 motor off of ebay, and change the little motor inside the actuator myself. Everything was going fine until I put everything back together, and gave it a try. Now my door won't unlock at all. All of the other doors work fine. I've tried the little key from the keyfob, and turning it kinda feels mushy. My guess is that something is wrong with my re-installation of the cables.

Yesterday morning my door was ajar, latched but loose, when I started up. I got a yellow warning triangle, a beep (I think) and message in a rectangle saying to put transmission in Park. My wife claims she saw a little car with open door symbol too, somewhere in the light show, guess I missed it.

10 days ago I bought my '05 Prius to the dealership to get the Brake Recall fix along w/ an oil change and inspection. Since then I took a road trip and put about 1,000 miles on. Two days ago, when pulling up to my house, I got a beep and warning message, since I was home I parked and decided to worry about it later.
The next morning the car turned on but would not move (crawled a bit forward and reverse but was basically dead). I checked the meaning of the warning light and its the Hybrid Systems Warning Light. From the information screen it appears the battery is drained and therefore electric motor won't function.
Of course I'm worried its the expensive battery dying on me but would this happen all at once or slowly over time? Unfortunately I'm at 117,000 mi so the system is out of warranty. My next thought was that something they had with the brake recall may have caused the problem (though it would seem odd it'd take 10 days to happen).

As far as the owner can tell, the car is running fine. He hasn't driven it aside from getting home after the light came on. It seems to give a very informative error message. What it's saying?

Although the key slides into the lock easily, it's a bear to turn the key left and right. I tried squirting some graphite into the key hole and working it with the key but that didn't do much if anything.
Is there a way to lube the internals that a homeowner--not mechanic--can do?

I have a persistent prob with the lock mechanism on the rear door of my mk4 golf, I don't suppose there is a picture tutorial on this subject. I have looked but can only find for the front door.

My car occasionally locks me out! When I lock the car using the driver's side automatic lock, it works fine, but then it won't let me back in. My repair shop says the left-side locking mechanism needs to be replaced but they can't get the part. The car is a 1992 Cadillac Brougham that I've had since new. The car is in great shape and runs like a top.

Ok. So I purchased my 2009 Prius on Saturday (4/23/2016). Couldn't be happier. I have a couple of things that I need to get to right away including a very small crack on the front windshield and the slide mechanism on the drivers side. I am a small guy and the seat belt currently goes across my lower neck (not a good thing). Now the passenger side will allow for the adjustment of the seatbelt height by sliding up and down but the drivers side won't budge. The seat belt itself works fine, just not the adjustment for changing the height.

2006 Prius, 114K miles. In the last week started getting the intermittent warning of "There is a problem with the parking transmission lock. Place the car on a flat surface and fully set the parking brake." Car would not start, would only go into neutral. All accessories work fine, seems to be plenty of 12V power. Did a lot of research and determined that the most likely cause was a failing 12V battery. Used the diagnostic mode to check voltages, had 12.1 at "READY", 11.6 under auxiliary loads, and 14.1 with engine on (I did get the car to start eventually but can't figure out how and under what set of circumstances it would start).
So I ordered a 12V battery and replaced it. After replacing, I still had the Hybrid warning light, but after stopping and starting the car 3 times it went away. Car worked fine for a day but now the intermittent warning has returned. With the warning on, the parking lock seems to be fully engaged (car won't roll even on a slope).
