I have changed the key battery before in the past with not experiencing this issue. Recently, I got the key battery low warning when parking the car. I replaced the existing battery with a new, fresh battery. All was well for about a week or so. Yesterday, I started getting the key battery low warning again. I'm not sure why I am getting that message again after replacing with a new fresh battery?
View 19 RepliesThis 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.
I have a 2010 Prius that I really love. In two separate incidents, I parked the car in a NYC parking garage and when it was delivered to me about 6 hours later the battery indicator only had two bars. There was no problems since the car recharged in about 15 minutes. On both occasions, I believe, the parking attendant left the key fob in the car the whole time it was parked. Is the car being drained because the key fob is in the car, or are the parking attendants doing something wrong? I can leave the car in my driveway for a few days and the battery is not as drained a sit is in 6 hours in the parking lot.
View 9 RepliesIs it normal that over night parking battery looses charge from 7 bars down to 2 bars? I never lock the car and leaving my key in it.
View 10 RepliesI recently parked my 2013 Prius in a concrete parking structure near LAX for 8 days. When I returned, the battery was dead - car was completely nonresponsive. AAA had to "resync" the hybrid system along with jumper cables to get me going. The technician said it was because the concrete drained the battery. I have previously left the car in underground garages for longer periods of time with no problem. Is this an urban legend?
View 15 Replies2006 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).
Had my car parked outside of work for about 12 hours yesterday, and in the NYC cold front, the parking break must have stuck on slightly. When I started to move, despite the fact I'd released the parking break, I received a warning in the MFI that said PARKING BREAK FAILURE TO RELEASE. I pulled the handle again and heard it pop just a little more off. Everything worked great after that. If I hadn't received the alert I probably would have driven off with it on. I'd probably have noticed the hesitation and checked the break again, but the alert was useful. Some of the warnings in the MFI can appear to be a pain at times, but it's amazing how thorough a job VW has done monitoring the cars systems and giving real time information if something doesn't work. You just have to make sure you don't get info overload from it all!!
View 4 RepliesIf the battery (that powers my car) is about to die, will the prius warn me? Will there be a light on the dashboard?
I need to know if the same lack-of-warning should be expected, or I need to know if the dashboard will tell me that my battery is about to die. I realize there is a dashboard menu in my car that shows battery life, but I never switch to that menu. I'm always on the menu that shows the temperature outside. So if I'm not on the menu with the battery, will there be some kind of text that comes on to my dashboard to warn me that my battery is about to die?
Someone said I can lift up the hood and look for some eyeball red/green image on the battery?
A warning light has come on stating" Key battery low". How do I fix this?
View 18 RepliesTonight I was driving home and the warning light came on. Thursday I was driving and noticed that the power lurched a few times. I switched over to see the energy usage and noticed that the battery was at the lowest bar. It stayed there for about 10 minutes. I called the dealer and started to head there. As I was talking the bars began to rise. It has seemed fine for the last few days until the lights came on tonight. I had just put gas in it. However, the car seems to run just fine and the traction battery seems to be charging just fine. There was no loss of power. Here in Texas it has been over 100 degrees for many days. I had an oil change at the dealer 10 days ago.
View 4 RepliesYesterday I heard a voice warning in my 2011 Prius. It said in effect "your battery is low". Glancing at the display my hybrid battery icon was two dots from the top, so I assume it meant the 12 volt battery. Not having a voltmeter, is there any way to check the health of my 12 volt which only has 33k miles on it.
View 19 RepliesI have my 2004 Prius in the shop for a replacement of the HV battery pack. The car has approx. 120,00 miles on it.
The battery failed with all the lights, warning symbols etc. I just got a call from the dealership that its going to take longer than expected to get the car back to me. They have the battery pack replacement, but when doing the replacement, they noticed that the cables were "corroded." The cables for the battery need to be replaced before they will complete the repair. But the cables need to be ordered and won't be in soon.
Is this common? for these cables to corrode? Would this problem have caused the HV battery failure?
I have replaced the Traction battery AND the 12volt battery. I clear all codes by disconnecting the 12 volt battery for a short period of time. I reconnect 12v battery and no warning lights. I drive for 10 miles and RED TRIANGLE, Check Engine and the Brake lights also come on the dash. 2006 Prius 130K miles.
View 16 RepliesBut while driving the hybrid warning light turned on in the MTD. A red car if I remember correctly. It was the hybrid battery over heating and to try and mess with the wiring going to the cooling fan in the right rear quarter panel.
View 6 RepliesI have a 2007 Prius with 92000 miles. All dashboard warning lights lit up the other day. Had it towed to the Toyota dealer and they first replaced the HV ECU. Now they are saying the traction battery needs to be replaced. They have had the car several days but they put me in a free rental.
View 3 RepliesMy 2010 Prius with 205,000 miles, has hybrid system warning, and the dealer has reported that the hybrid battery needs to be replaced, there is a prob with one module but they do not repair the batteries only total battery replacement. Also needs front brakes and tune up. I did not expect the hybrid battery failure on this 2010 Prius since my 2008 Prius (184,000miles) had no issues thus far with the battery. Both cars are every day drive cars. Both cars have been really dependable and only routine maintenance.
I had no issues with the hybrid battery until after my last service when their was some factory recall having to do with the cars computer system, and routine oil change. The car stalled out the next day, but then restarted, this was odd it felt like the car was running but would not go into gear nor respond to the gas pedal, I'm calling it a stall, I'm not sure if this is correct terminology. So, it did this a couple of times the day after service, I was shocked but I just killed the car and restarted no other issues for about 3 weeks. Then I got the hybrid system warning on the computer screen on the dashboard, UGH.
I never expected my newer 2010 Prius to have a hybrid battery failure before my 2008 older Prius.
I'm looking for options with Prius over 200,000 miles. Both have been maintained through dealer services. Dealer reports the 2010 Prius with this issue is worth 1000.00 . I'm at a loss I really want to keep the car, but now I'm unsure, and obviously think it's worth more than 1000.00.
I just purchased a 2006 Prius with 89k miles and it has a problem with the drive train and randomly losing all power on the freeway causing me to make emergency shoulder stops to reset the car.
The symptoms are as follows:
-red triangle on, orange circle with ! on, check engine light on, hybrid monitor green car symbol is red with ! in it
-traction battery fan is always on when car is powered
-the car has never driven under electric power
-shifting problems, sluggish acceleration and all power loss on freeway
-hybrid monitor system lies and shows the battery full one second and empty the next.
2005 Prius I picked up a few weeks ago decided to eat both of it's batteries for lunch and leave me high and dry. I replaced the aux battery yesterday which I was lucky to get at cost at the toyota dealer since the aux battery was original. Put it in and all was well with the car for the rest of the day. Got in it today and headed out and was welcomed with the big stupid "!" triangle, the regen brake warning, check engine light, "PROBLEM" written on the display with a picture of a "!" inside a car outline, and some severely reduced performance. So I looked online and found a place with a bunch of low mileage batteries out of smashed up 2009's.
View 19 RepliesFirst a little background on the car , it has 217,000 miles. The battery was just replaced with a used one. While taking it through the carwash, she put it in neutral and a minute or two later she got a warning that the battery was not charging and to put it in gear. Sounds like the battery is having issues to me. She has a 60-day warranty.
View 10 RepliesMy 12v battery died, I tried recharging it etc, but it was dead so I took it to my local Toyota dealer and had the battery replaced.
Because I had the battery off, there was a VSC warning light, which I thought that the Toyota dealer could reset. They re-calibrated all the warning apart from one, they say that the Yaw sensor will not clear it's warning and needs to be replaced.
if I can reset this warning myself, or do I really need to replace this sensor?
I have a 2007 Prius. We left for vacation for 2 weeks. Came home. Started the car and then all the lights came home. I thought the battery must have drained. But the lights are all on with a new battery. Is there a way to clear all these?
