Prius (Gen 3) Fuel :: Car Enters Into Stealth Mode On Highway Speed

I have only been driving my Prius for a month. I have been paying close attention the to the Car energy usage screen. I have been noticing the car (while on cruise control) entering into stealth mode (Engine seemingly off and power getting drawn from battery only w/ about 3/4 bar on EV) on the highway @ 60mph going down a slight decline. I have been trying to mimic this on my own w/o the cruise control, but no matter what I try (P+G and other techniques) I cannot get the same results.

Prius (2004-09) :: 2007 - Unusual Noise When In Stealth Mode?

I have a 2007 Prius with about 77,000 km on it. Lately I've noticed that the car would make an unusual noise sometimes when driving at around 50 - 60 km/hr in stealth mode, with slight accelerator pressure such that the energy monitor shows power flowing from the battery to the motor (ie - not gliding or regen braking).

Prius (2001-03) :: AC On Max Setting Would Go Into Stealth Mode

My 2002 Prius A/C is acting strange. From what I understand, if you have Max A/C on it will keep the ICE running. Lately my car isn't doing that. Whenever I'm at traffic with the Max A/C on it will go into stealth mode then it will turn the engine on then back off again in a cycle.

Also whenever I hit the brakes or simply slowing down with the ac on the whole car will shake violently like theres a strong earthquake and its about to stall unless I shut the A/C off. This only occurs when the A/c is on btw.

Note :: I've had my ac charged so its not out of refrigerant. But I don't know what's causing it.

Prius C Fuel :: Cruising At 40 Mph - Stealth Mode Or Lightly Loaded ICE?

Conditions often allow me to choose between moderate to high current draw in stealth mode, or a lightly loaded ICE (<1300 RPM). How much power do you find it's best to allow in stealth mode before you decide to give the throttle a slap and fire up the engine?

Prius (2010-12) :: Top Speed In EV Mode?

What's top speed for EV mode? I was able to keep it in EV when driving through town, after a hill, and keep it around 41-42 for a little while before my speed dropped and I had to use a little more throttle.

I don't understand why you can't lock in EV and deplete more of your battery at times, such as a few miles before getting on the freeway. Seems a bit wasteful, since the highway portion would give you plenty of time to build up charge again.

Prius C :: Ev Mode Deactivated Excessive Speed

I have questions about ev mode for my Prius c. I just got the car in December and was using the ev mode frequently. It would work when I was going 25mph or lower as long as I wasn't rapidly accelerating or climbing a hill. Now it seems I barely get up to 10 mph before it clicks of saying "ev mode deactivated excessive speed". This happens when I break to come to a stop or when I slowly accelerate. I took it to where I bought it and the kid rudely told me to read my manual so I did and this isn't covered. I have lost 10 miles on my mpg and I have been doing the same commute since I got this car. Before I was getting 52.3 now I'm lucky if I get 40.

Prius (2010-12) :: Gen 3 - EV Mode Disabled Due To Excessive Speed

I was under the impression that when you enable EV mode the car will stay in EV till around 40 mph or something close to it? I can't seem to go above 10 mph without getting a message stating "EV Mode disabled due to excessive speed"? Is this a glitch or can you really only go 10 mph? That seems pointless if that is the case.

Prius V :: Engine Is Running At Very Low RPM In ECO Mode At Steady Speed 40 MPH

I've noticed the Prius V engine is running at very low RPM in ECO mode at steady speed of about 65km/h (40mph). Fuel consumption vary between about 4-5L/100km (58 - 47mpg) and RPM is showing about 1100+

I usually see RPM of about 1100 to 1400+ which is very good; so I'm not surprised this engine is very fuel efficient.

Prius V :: EV Mode - Gaining Speed Faster Without ICE When Taking Off From A Stop

I've read several posts that suggest the EV mode is mostly useless. I disagree. I've noticed that it's useful in gaining speed faster without the ICE, when taking off from a stop. Especially if I'm in traffic and I don't want to annoy drivers behind me.

I've noticed that conditions have to be met in order to do this, such as engine warmed up etc. but I find it very useful, and I am seeing improved MPG when doing this. I've had my 2013 PRius v Two for almost a month now.

Prius (2010-12) Fuel :: Can't Get Into EV Mode - Excessive Speed Message At 8 MPH

Just bought a 2010 Prius IV and loving the car.

Minor annoyance, but wondering why it's so difficult to get the car to enter or stay in EV mode.

When I'm able to get into EV mode, it often beeps that it's leaving EV mode due to excessive speed, but I'm often doing barely 10 mph when this happens. I was under the impression that I could do up to 25 mph. Yesterday, I was floating at 8 mph and it said that was excessive speed.

More often, though, I can't even get into EV mode. It says "EV mode currently unavailable" and why. Doesn't matter if I'm not moving or if I'm driving slowly.

Prius Plug-in 2012-15 :: Low Speed Electric Acceleration In Hybrid Mode?

Just curious, is the low speed electric acceleration in *hybrid mode* generally, seat of the pants, noticeably more robust than that of the 'regular', 3rd gen Prius? By low speed, I mean starting off from stop lights in normal driving.

Why do I ask? In 3rd gen Prius, electric acceleration lasts only a few seconds from a stop, maybe up to about 15 MPG roughly with light acceleration. With heavy throttle, gas engine comes on about right away.

How does the PiP behave under moderate acceleration from stop in hybrid mode? Could we say PiP accelerates on electric drive in HV about 6 MPH per second +/-x up to 25 MPH +/- x on level ground, etc....?

3000GT/Stealth :: 1995 3000GT - Overheating On Freeway Running At 80 Mph And Maintaining Speed

I have a 1995 3000gt sl. When im on the freeway running at 80 mph and maintaining that speed it starts to overheat.I can reduce my speed and it starts to cool down I can also turn heater on high and that cools it down I cant hit the exit ramp and by the time I get stopped at the end of ramp its cooled back down.I can start it and sit with it running and it never gets hot.If I stay below 55 I never have any overheating its only when I increase and maintain 75 or faster I have a problem. Also when it was hot outside I turned my air on max cool one day and it got hot real fast.So to fix that I just didn't run my air any more. then a few months went by and this started to happen.50mph and slower its fine.But at freeway speed limit it starts running hot. Only with increased speed to the engine does it start getting hot.

3000GT/Stealth :: 93 3000gt VR4 - Check Engine Light Comes On Goes Off When Driving At A Speed Of 55

I have a 93 3000gt VR4 with 214,000 miles on her at the moment. As I am cursing at a speed of 55 the check engine light comes on and stay on for a while then as sudden as it came on it goes off still driving at 55 or less depens on traffic. My question is why is this happening? I took it to AMMCO to have the code check but they could not because the check engine light is not constantly. I do not have a code sxanner for the car to read the codes if any. The engine runs strong I tried to see if I could get the check engine light to come on but to no avail. Could it be a sensor going bad or the ECU I had trouble with it before and had the dealer replaced it.

Prius (2004-09) :: 2007 - Cannot Change To EV Mode Now

I just recently bought a 2007 priuswith 77k miles and really love it and just 3 days ago installed the EV switch (manual button, not the coastal one) because of my plans to get it to plug in in the near future, and it worked very nice until today. No matter what i do and when i press it, it just keeps saying "Cannot change to ev mode now" doesn't matter if i push it before the ICE warmup or after. its in the range where it should be working like plenty of battery, not pushing the accelerator at any time, under 34mph, and not while the ICE is running....it was in the mid 80's today which is cooler than last 2 days. I'm just not sure what to do anymore...I do have a check engine light on for 02 sensor but it has been on since I bought the car.

Prius (2004-09) :: 2007 - Can't Put It In On Power Mode

We got this 2007 used in June and I love it but recently I have been reading the manual and noticed the power on mode. I have tried numerous times and different ways to put it on with no luck. It powers up for ignition with no issue but I can't just listen to the radio or reset the tire pressure because it can only go into ignition mode.

Prius (Gen 2) :: 2007 - Cannot Change To EV Mode Message With Three Beeps

I have a 2007 base model and for the last two months I keep getting three beeps and on the mfd shows up "Cannot Change to EV Mode Now". I haven't done any mods to the car. It seems to happen during the first couple of miles after start up, but it also happens when I need a little extra power to pass a car on the highway or if I've been coasting for a few seconds and then hit the accelerator again. I live in Atlanta and the temps have been 60-80 degrees for the last few months, so it's not getting to hot / cold.

This might be a coincidence, but it seemed to have started doing this after my last emissions test. The gentleman who did the test acted like he had never seen a prius before and took him a good 10 minutes to hook up his equipment. As this is going on, he proceeds to touch all kind of buttons on the MFD and got to screens I have never seen before. It wasn't until a younger co-worker came over and showed him how to hook it up that he stopped messing with buttons. My question is, could he have done anything on the screen that would cause the issues I'm having.

Prius (2004-09) :: 2007 - Traction Control Computer Stuck In Limp Mode

I have a 2007 Prius and it will be my first car once I get my license. It has a bad traction control computer and is stuck in limp mode. I have a neighbor who has worked on these and will show me how to replace it. Right now I have two questions. I keep coming up with how to disable it not the actual part.
