About three weeks ago while driving my Prius and accelerating the car jerked suddenly and warning lights came on. I was able to read the above codes with tech stream. The car still drives but has limited horsepower. The engine also does not seem to rev down like a normal hybrid. I have not had good experiences with the local Toyota dealer.
View 13 RepliesOn my way home tonight - As i was making a turn near my home i got a bunch of warning lights that came up. Red Triangle, VSC, Check engine and i believe the Brake Warning (The little Circle with the ! inside).
The Car drove fine till i got home (only about a mile away at that point). Looked under the hood- nothing that stuck out as being busted but only a quick glance. If i still get the lights in the morning, Off to the dealer. Don't have a Code reader so cant pull anything here at home from the car.
If its related or not is the A/C seemed to get a bit weak in the minutes before the lights turned on - I remember intentionally cranking it up which is something i normally don't do. because the A/C is normally great in the car.
I have to say in the 4.5 years I've had the car - this is the first time I've had this kind of issue. The battery died and had to be replaced like 9 months ago but i didn't get the amount of warning lights I am getting now.
Strange thing happened yesterday. After changing my oil as I left my friends house I had a couple weird indicator lights. ABS warning, the yellow indicator next to that ((!)) and the traction control light were all lit and solid. Brakes felt a little unusual. Less sensitive than normal but working fine....
I pulled out of his driveway, then went about 20 feet and pulled over. Shut the car completely off, turned it back on and all was normal.
The exclamation indicator was not lit nor Check engine and no messages were displayed. No beeping . It's almost like I had the car in some kind of brake test mode or something.
Here's what I did before I left his house:
While on jack stands I changed my oil. While it was still up on jacks I turned on the car to run the engine for a moment. (I put it in neutral to let it run for about 1 minute.) No leaks .. buttoned up the car, put it back on the ground. Filled oil to the top line and ran the engine again for maybe 30 seconds. Everything normal. Then I had it in "ON" mode while I checked my tire air pressure. (I had a warning indicator about that.) Once I had tires correct I put the car in ready mode. All indicators off and normal. Shut off car then had it in accessory for a little while. (Listening to radio) It was after this I left his house..... So I definitely cycled the car on and off several times.
I drive my 2005 Prius 40+ miles each way for my commute. I bought it in the fall of 2007 with 56k miles already on it, and with my commute I'm up to 140,000 miles already.
This morning I was about 5 minutes from work, cruise control on, and deeply absorbed in listening to a podcast. I was startled out of my reverie by several things happening simultaneously. The car beeped, the cruise control kicked off, and multiple warning lights lit up on the dash, with a warning icon of some kind also on my MFD.
(Once stopped, I looked up the warning lights. They were: Master warning light; Check engine light, or "malfunction indicator lamp", according to the manual; YELLOW Brake system warning; VSC warning light. On the MFD, the Hybrid System Warning Light was on.)
I was on the highway doing about 70 and I had just crested a hill, so I allowed the car to coast on the downside while trying to access the situation. I cautiously pressed the accelerator, and though the road noise made it impossible to hear the engine, the car seemed to still be driving normally. The Energy Monitor still showed normal flows between battery, engine, and wheels. I had one final, short uphill climb before my freeway exit, so I chanced it. I took it easy and allowed my speed to decrease on the uphill so as not to push too hard, just in case. Once off the freeway, most of the remaining mile is downhill or flat - I can often make it to the office without the engine, and in fact I did so this morning.
Once at the office, I put the car into Park and grabbed the manual so I could identify all the warning lights before powering off the car. I turned off the Prius, let it sit for 5-10 seconds, and powered it back on. The brake system warning and VSC lights did not come back on - only the master warning light, and "check engine" lights reappeared, and "Problem" on the MFD was again replaced by the Hybrid System Warning icon. After the usual 10 seconds, the engine started normally and responded to the accelerator.
One additional note: After the freeway exit, my car is usually at 1 green bar or just below on the hybrid battery. Immediately following the freeway exit is a steep downhill that usually puts the SOC to completely full. That was the case again today, and as often happens, that full charge was able to take me the rest of the relatively flat, distance to the office at my usual 25-35 mph. I mention this because whatever might be setting off the warnings, the Prius still seems to be managing the charge level normally; at least in the admittedly short period I was able to observe it after this occurred.
We've got a 2011 Prius with a little over 24k miles on it . For the last few months we've been having issues with it starting. First I thought the remote barriers were dying so I replaced them , I thought my wife might have been trying to start it incorrectly till the problem happened to me a few weeks ago. What happens is you try to start it (foot on brake, press power button) and all the warming lights pop up , radio turns on , navigation turns on but car doesn't start. This morning it happend just once , yesterday I had to try it maybe 10x before it finally started up. The dealership had it last Saturday and of course it started every time for them and they couldn't duplicate the problem , they also said they ran whatever tests they do on it and it didn't turn up a problem. FWIW we had the software recall update done in June.
View 19 RepliesStarted my 2010 Prius the other day and the traction control, brake light, abs light and a yellow Astrix light came on and wouldn't go off. The car drives and handles just fine, brakes feel normal. I have tried resetting the lights with a trick with a paper clip someone else posted, but it didn't work for me.
View 7 RepliesThis morning when I started my Prius 3rd Gen 2011, I noticed three yellow lights being on. These were; something similar to handbrake light, ABS light and then the stability control light. All are in yellow. Checked tire pressure and found that one tire was low and filled it. Also, brake fluid was near the low level and I topped it. The lights are still on. I switched on and off several times but the lights are still on.
View 4 RepliesMy Prius yesterday while driving slowly (under 10 mph) all the dash warning lights came on(triangle, cel, trac control, brake). the gas engine started and the message came on that says: "check hybrid system". Today when I went out to check there only two warning lights on (triangle and cel) with the same message displayed. My question is can the vehicle operate without damaging anything if I drive it as is? I have read on several threads that the engine will not start if the hybrid motor(s) are not working. Since my engine starts and runs I have to believe the motor(s) are working.
View 19 RepliesMy 07 has 149K on it and I never have checked the oil. I do have it changed every 5K and no one has ever mentioned it coming in low. My last oil change was at 145K and about 2000 miles later the master warning light would come on when I slowed down fast, especially if there was a turn. I noticed this on the twisties driving up the west coast. The problem then went away after a couple hundred miles. Then recently it started doing it again and so I checked my fluid levels everywhere just in cast that might be throwing the warning light and found my dipstick was bone dry.
I am surprised the warning was so general. Why not an oil light? or an oil pressure warning? WHen the master light came on, the screen just said "problem". Kinda vague for such a specific and important matter. My guess is that the oil got so low that the oil pump sucked some air due to the acceleration when cornering or stopping. (negative acceleration).
My question is what would make it start using oil suddenly. True I didn't check it b4 so I have nothing to compare it to, but as we all know, the Prii do not use much oil and if in fact it was so low that it was sucking air 2000 miles after an oil change, they either forgot to add oil or else it started using the 1 qt/ 600 miles that the owners manual tries to tell us is normal. I seriously doubt they shorted me on the last change. BTW I added some oil ....
i have a 2010 with 182k miles. The vehicle will jerk like the drive is engaging and disengaging several times (repeatively) when going down hill. It doesn't matter how fast, but I notice it does depend on the ECO indicator. The ECO gage always indicates above the mid mark but ranges between no more than quarter to an inch and quarter above. If I speed up it stops and if I slow down below the mid line it will stop.
View 13 RepliesI commuted to LA 2-3x a week. The mileage on my car is now at 90k. I have had an average of 40 mpg since new, but suddenly it began to drop. We took it to our local Toyota dealer and was told it was most likely a cable that needed to be cleaned. That was $160. It didn't work.
View 10 RepliesI am using a 2012 Prius and I was running around 23KMpL average. For sometime I am seeing my mileage around 17 - 18 KMpL. What could be the reasons for this ?
The only change happened in between is that I had a accident which I had to replace the front buffer.
I've notice this several times when leaving from work to go home. The first quarter mile I will be starting off nice and easy, the engine is on and then suddenly a lurch of power. Now its not giving me a wipe lash! But I can defiantly feel it and out of the corner of my eye can see my passenger's head move back slightly. So not so subtle either. It will only happen once.
It is not going from battery to gas as I mentioned engine is already on. I am in eco mode the whole time. I am not hitting the gas any harder. And I am not going into the power band all the way right of the bar. I am staying steady in the eco area.
I have a strange issue that just started happening. A whirring sound comes from the vent in the back seat I believe which sounds like escaping Air. Not like the last 2 years I've owned it. At the same time I noticed that the accelerator now takes a second to engage after I hit the pedal from a stop every time. Furthermore the engine seems to be over revving, as if engine braking. I've restarted the car a few times. I've checked all the fluid levels.
View 7 RepliesFirst time Prius owner Aug 2012. First 2 tanks of gas very impressed at 50-51 mpg. Then going slowly (10mph) through a parking lot I heard a strange noise on passenger side underneath the car. The best description is that it sounded like a steel lawn rake being dragged under the car on the asphalt. It lasted for about 30 seconds, then quiet and I have not heard it since. No sign of issues. No dash warning lights.
My next tanks rendered 47.5, 48.5, 46.5, 45.75 mpg. Then in the last 2 tanks suddenly at 41.5 and 42.75 mpg. This seems like a very major drop in mpg. I have been reading the comments regarding outside temp etc. and I will make adjustments. It just seems extreme and the "noise" is now making me wonder if some electrical component failed and is adding to the poor mileage issue.
I have been driving 2013 model for five months. I noticed that whenever any front wheel rolls over cat-eye on the road and any sudden small bump then it generates noticeable clicking sound. I went to the dealer and they said it is normal and comes with all such cars.
View 19 RepliesI had just picked my kid up from school, as I turn out of the parking lot my A/C stops blowing cool air, I check the A/C screen and it still says it's set on High with temp at 68. However, it is blowing very low with warm air. Seconds later the dash lights up with numerous warning lights. I'm on the highway and I'm able to gather speed, but each time I do I hear the engine revving like crazy. We only live a few miles from the school so I am able to make it home. Once home, I turn off the car and turn it back on. The only warning lights displayed now are the red triangle and the yellow check engine light. I turn the car off, pop the hood, I check the belt and it was fine. I checked the oil and it seemed fine. I check the coolant overflow and it was empty.
View 15 RepliesWhile driving my 04 w12 a few months ago i noticed a "stutter" or brief jerk while driving. the next morning i had a "coolant level" warning. i took the car to a mechanic i use who diagnosed the problem as a broken coolant line involving the transmission cooler, with the result that coolant migrated to the atf. indication was that the tranny was toast, along with the atf cooler. I authorized a repair (not inexpensive), keeping costs down by installing a used tranny. since the car was "fixed" i still got a "jerk" usually in fourth gear, sometimes in third. i took the car back and was told that the tranny was flushed numerous times and the transmission was reflashed. i picked the car up yesterday, but i still get the "jerks", now usually in third gear.
View 3 RepliesI noticed that if I forget the lights on when locking the car, I don't get any warning. Is that normal? On the Toyota, you get that chime sound that tells you you forgot something like the key in the ignition or the lights on.
View 16 RepliesBought a 2010 lexus rx450h with 45k miles. Last night on my way back to home suddenly its front lights went off without any warning. Instrument panel was illuminated but no lights even the indicators and head light dippers , front fog tights were not working. Few buttons on panel like tail gate, height control were also not illuminated.
I stopped the car and after 10-15 minutes of fiddling around. Switched on and off the car a couple of times. Its lights came back. Now im a bit worried what caused this sudden black out. What should i check so as to get this thing not happening again.
All my dashboard warning lights are on in my car and won't turn off ( as shown in pix ) every time I start my car. I wonder what's wrong with my car ?
