Prius (Gen 2) :: Hybrid System Fail / Replaced Battery But Failure Exists
May 20, 2013
2006 Toyota Prius, bought new in Oct 2006, currently at 90,000 miles.
It just recently broke down on me about a month ago, the dashboard lit up like a Christmas tree with every possible light flashing and nav screen showing "problem." I took it to the Toyota dealership and they determined it was a hybrid system fail and replaced the battery.
After this, I'm thinking all is well. I go out of town this past weekend 130 miles away from where I live and day 2 into vacation my dashboard lights up again! Same lights, flashing red triangle, Vsc, check engine, etc. it gets me back to my hotel but the next morning the engine won't start. At least the first time it broke down the cars engine worked and was somewhat drivable.

Actually 2 very similar questions about my Prius 2007.
1. My water pump was replaced by a dealer due to failure some half a year ago at 95,000 miles. Yesterday, after oil change (98,000), I was told it is recommended to replace engine coolant. Does this sound right? Don't they change coolant when replacing the pump?!
2. Identical question about HV pump. It was replaced at 80,000. Now they recommend do change the coolant for hybrid system. Don't they have to do it when replacing the pump?
I want to do everything necessary to maintain the car. But don't want to spend money for something that is not needed.

Two weeks ago a large, industrial truck dropped a piece of bent steel pipe on the interstate in front of my 2010, 50k miles, Prius and (sadly) I was forced to hit or swerve into rush hour traffic and cause an accident. It tore up a good part of the cooling system and did some body damage. Of course I didn't know this at the time, but it began to overheat, so I pulled off the freeway and had it towed to a body shop. After about ten days, I got my Prius back.

I have a 2010 IV Prius that has been having the following issues starting up / turning off:
On February 4th in the evening: car wouldn't start. Started on 5th try - showed "HYBRID SYSTEM OVERHEAT."
On February 15th in the evening: car wouldn't start. During multiple attempts to start hybrid screen to the right of speedometer flickered / went in and out and was faint. Started on 5-6th try.
On February 16th in the afternoon: car wouldn't start. Hybrid screen to the right of speedometer flickered and went in and out during startup attempts. Eventually car started at 5-6th try - but display to the right of speedometer did not come on at all. Car felt like it was running on engine only.
Took car to Toyota dealership. They had it for 2 weeks and could not figure out what the issue was. Car did not show any error codes. Said they did not experience issues either. Gave me the car back.
On March 3rd, as soon as I got the car back and while still in the dealership parking lot, I pressed the start button with my foot on the brake and only the AC / radio came on. Called over service advisor and when he came tried it the car started up fine.

The other day, I was driving my 2006 Prius on I-20 in Shreveport. As I came off the exit and approached route 80, my navigation display read "PROBLEM", and the car suddenly coasted to a stop. All of this occurred in about 100 feet, so I was lucky to be able to coast the car to the shoulder, because it just died where it stopped. If this had happened while I was on the highway, my whole family would have probably been killed, as there was no way we would have been able to safely get out of the way of the multitude of semi trucks that drive that road.
I attempted to re-start the car, and the red triangle warning appeared on the display, along with the little car with the exclamation point in the middle of it, otherwise known as the hybrid system warning icon. Needless to say, the car would not turn over.
I immediately called Toyota to see if they had any info to get the car going. Toyota was absolutely useless, and the customer service agent said the only recall showing on my model was a floor mat recall. I told him that I knew he was only doing his job, but it was a shame Toyota actually believes Americans are stupid enough to believe the floor mats are the problem. Luckily, we had AAA, so the car was towed home, after a two hour wait.
Diagnostics : I checked all fuses and relays, checked battery connections, and saw no apparent problems.

2010 Toyota Prius III with just under 60,000 miles. The car has been serviced at Toyota from day one (by us and by the previous owners) and runs like a champ. Well, did.
Last week while driving home from running errands the Check Hybrid System light came on for my wife. The car was still running so she drove it home for me to look at. I hopped in and noticed the gasoline engine wasn't turning on. I took it for a spin and even when I floored the car the gas engine wouldn't turn on. Since the nearest dealership is 15 highway miles away I knew we weren't going to make it there on electric power so I had it towed.
The Toyota dealership called me the next day saying when they started the car the light was gone and the car ran fine. They did some troubleshooting and found nothing wrong. They said it might have been a glitch and to come get the car. Not even 3 hours later the light turns on again. Again the gasoline engine goes silent, but this time I didn't even make it a mile and the electric power shuts off as well! We coasted to a stop and had to have the car towed again. This happened out of nowhere and could have been a very serious safety situation had it not happened on the road we were on.
This time the Toyota dealership had a little more to say. They said that their diagnosis has determined that the inverter is shot and they will have to order a new one. They said this failure is extremely rare (the service guy I spoke with had never seen this issue).

My wife was driving our 2009 prius this morning. she said the red triangle, this other yellow circled, light with an ! came on plus in the display window the car icon with the ! came on. Manual states that this is a hybrid system failure.
On very cold mornings the car smells very hot for a period of time. She said this happened again.
I tried to do a reset (turning it off and on atleast 4 times) did not work. So I had it towed to a dealer tonight and I started it again and this time very hot smelling and a whole lot more lights were on, ( brakes lights, almost all of the lights I would say.)

I have an 07 Prius which I bought used in 2011 and which has been fine (except for some A/C work last year) but got the 'triangle of death' this morning and having towed it to my regular shop, they tell me the code (they couldn't give me the number) simply said 'replace hybrid battery'... the car has 102,605 on the clock.

I just switched out my hybrid battery and put in a brand new one. Now, the car isn't doing anything and all that's on is the check engine light. What now? I was told I had to tow it to Toyota and have them reset the computer. Sound right?

I have a 2010 Prius, currently at around 69,000 miles. Back in Feb 2015 (when it was just under 60,000) I was driving on a city street and hit the accelerator once a stoplight turned green - immediately as I took off (at a normal rate of acceleration) my 2010 Prius made a loud noise and I got the red triangle of death, with a "Check Hybrid System" message. The car quickly shifted into "limp home" mode and I was able to make it back home as I was only about a mile away.
Got towed to the nearest dealer the next morning and after tons of testing and going back and forth, they replaced the transmission and inverter (was able to get it covered under powertrain warranty), and I was on my merry way. No issues until last night.
Yesterday evening, I am on a city street and get a warning beep. I look at my dashboard and this time I have a yellow exclamation mark with the "Check Hybrid System" message yet AGAIN. Towed the car to the nearest dealer and am now waiting on next steps. Only update I've gotten so far is that they are still trying to diagnose the issue, and are getting 4 error codes in this process, 2 of which are new. I am waiting on the technician to tell me what the actual codes are - hopefully should get them tomorrow.
I would hope if it's another issue with transmission or inverter, it's covered under warranty given I replaced both less than a year ago. However I'm not sure and am worried that it's going to be $$$ in case it's something else that failed. Plus I'm getting serious doubts as to the safety of my car - what if I had been moving at a high speed on the highway during either of these situations?

I have 2005 Prius with 300k miles. I started throwing P0A80 code. I removed the battery and checked all the modules and found 2 of low voltage, ordered them from Ebay and replaced them. I placed the battery back in the car and started the car but got P0A80 code again. I purchased the grid charger from Hybrid Automotive and connected it according to their instructions for 24 hours. I drove a car but got the red triangle again and P0A80 code again. I removed the battery again and tested the voltage of all the modules and these are the readings:

Jumped into the Prius this morning to discover dash lights working, no radio etc so vehicle would not turn on. Replaced the auxiliary battery (about 5 years old.) Now all dash light, radio etc are looking great BUT:
- Enngine will not engage
- Message stating Check Hybrid System
- Various waning lights on dash (yellow waning triangle, swerve icon on left)(battery, brake, chech engine, steering wheel?) and abs!!!on the right)

I have a 2003 Prius with just over 116,000 miles. When my wife cranked it a couple of days ago, the "Hybrid System Warning Light" came on.
As advised by the owner's manual, we didn't drive the car. We took it to the local dealership to be checked out. When I called for an update last night, they said that the computer indicates that the hybrid battery is leaking.
So I guess my questions are:
1) What kind of lifespan is typical of a 1st Gen Prius?
2) How many more miles are reasonable to expect from the gas engine?
3) Is there anything I should be aware of to make sure I'm not taken advantage of? (eg is there a credit for the battery since it has valuable components)

I haven’t been on these boards very often since getting my used 2008 Prius because until now it has been very kind to me in terms of not needing mechanical repairs. Unfortunately that good streak seems to have come to an end. Driving home Monday evening (after ~30min freeway driving), my master system warning light came on, accompanied by the hybrid system warning light. I didn’t know what the latter was – had to look it up – but I immediately pulled to the shoulder. The car was driving normally, however. Since shops and dealers were closed for the evening, after much debate I ended up having the car towed to a family friend’s body shop; they were still there and had a scanner to check the error codes for me. My car was on the side of the freeway for well over an hour with hazard lights on and the dome light on and off occasionally as we got in and out of the car. By the time the tow truck arrived, I discovered that the 12V battery seemed dead; car wouldn’t boot up all the way, wouldn’t shift to neutral and didn’t want to power down – I had to try turning it off upwards of 10 times. I was surprised, given just the hazard light and limited dome light usage. We jumped it, got it in neutral and on the truck.
At the body shop, they said there were no error codes related to the hybrid battery; something about transmission that wasn’t clarified, and errors for low voltage on the 12V battery. With everything off, it measured 10-something V; something higher when turned on, but they believed the problem was a dead 12V battery. I was surprised that it would suddenly give out in the middle of driving, but we went ahead and replaced it the next day. I picked up the car Tues evening, and had no problems driving it home, to work the next morning. Unfortunately, during my drive home – strangely at almost exactly the same location as the first time – the same hybrid system warning light came back on. I’d driving about 70 miles with it off at this point before the reappearance. This time I didn’t pull over to the side (had enough of that before) but rather drove a few more miles to a parking lot where the car has now stayed overnight. I note that the car seemed to drive perfectly normally during that time; no loss of power.

My 2010 Prius sat idle, parked for 7 days while my wife and I were on vacation. When we went to pick up the car, the airport valet said that the Prius wouldn't start, and so that they'd have to jump it. I approved the jumpstart, and got into the car. We got about 1/4 a mile before the display totally freaked out, including the "check hybrid system" as well as about every warning light there is. The car was beeping, acceleration was lost and it eventually died on the side of the road. The car would not start back up.
Had it towed to the nearest dealership. Initial diag from the service manager was that the 12v battery was dead. I approved replacement of that, and also authorized clearing out "a few software alerts". Got a call later in the day from the same manager (very nice guy) and there are about 11 errors that cannot be cleared out. Now he's asking for 3-4 hours labor to "trace the wiring" as suggested by Toyota. Apparently the tech had been in touch with them all day.

I have a failure on the evap system of my 2002 Escape, and need the proper testing procedure for this particular purge valve. I was able to fix the purge valve on my 2013 Explorer, with no issue, but the Escape has a different type and I'm not sure I'm testing it properly. I want to verify the purge valve is working properly instead of just throwing parts into it. I know it is likely either the valve or the gas cap, but it could be something other than those two items, so I want to get the simple stuff checked out first.

i drive a 2007 XC90 V8 with 76000miles and recently i got a power system failure message and battery light went on , so took it to my mechanic and he tested the car and it was tuning out 11volts so he concluded it was the alternator, so he recommended changing the regulator and i got a new regulator made by Bosch and it was installed and upon starting the message came back on and the battery light as well and upon testing it was producing 15.4volts , now its overcharging , what do i need to do ? should i buy another regulator ? as my mechanic says alternators hardly ever get damaged but the regulator is the one that usually gets damaged...

Had the Check Hybrid System and master warning light come on today. Took it to the dealer, who, after a couple hours, told me that my "Hybrid Water Pump" needed to be replaced.

I have a 96 Cadillac Deville Sedan. Last year, I had problems with the heat and A/C working intermittently. Then both crapped out. I went the summer without A/C...waiting for winter. Have gone all winter with no heat, which is not a huge problem, since I live in Florida. However, I'm planning on taking this car on a 1600 mile journey to Maine. So on Thursday, my bf installed a new HVAC fan motor. Or, yeah, whatever you call them. It worked and the car produced heat. I had a parade to go to Thursday night, so I drove the car there and it was fine. On my way home, the car was revving, like I was driving a lawn mower. Then, while I was still driving at a low speed, the mph went to 0. During the 10 mile drive home, which included interstate, the mph returned and the car acted normal. Then the mph went to 0 again. The speed sensor failure light came on, along with the check engine light.
I thought maybe while replacing the fan motor, the bf might have unhooked the speed sensor. This makes sense to me. But the bf checks and can't find anything obvious.
Today, when I first start driving the car, it again sounds like a lawnmower. The rmp is into the 3000 and 4000 range, while I am driving (approx) 15 mph. If I step on the gas, the car lurches forward, then returns to lawnmower status. The mph is showing 0. The instant mpg is also remaining at 0. The fuel range is showing numbers, but they are not correct, since there are 14 gals of gas in the car and the range is at like 85 miles and declining. I get around 20 mpg. So that's not an accurate range. After a few miles, the car stops over-revving and sounds normal. On the interstate entrance ramp, the mph started working, and worked for several minutes, then reverted back to 0.
So, to summarize. The check engine light is on all the time. The speed sensor failure light comes on in the beginning. The struggling lawnmower act lasts for the first few miles. Lurching if I step on the gas. Then, it might drive normally. The mph stays at 0. Every once in a while, the mph will start working, then stop again. What could have happened during this fan motor repair to have caused this? Or is this just a huge coincidence?

I just wanted to share my story here. Last week on a routine trip on I-5 warning lights started flashing indicating hybrid drive failure. The car automatically shifted into neutral and I was limping along down hill. Luckily I saw a downhill exit and had the foresight to turn off where to my horror I discovered that my brakes didn't work. So I had to coast to the bottom of the hill and again made a quick decision to turn into a slight uphill side street to force myself to a stop with the parking brake. At point the car completely died and I couldn't even shift into neutral to push it.
After towing it to AAA and avoiding a collision on I-5 (if I pulled into the shoulder without breaks I likely would have crashed into a retaining wall) and then not being smacked after I got it to a stop I was pretty shaken...I'm lucky to be alive.
