Prius C :: EV Mode Doesn't Turn On - Car Has Only Gas Engine Running
It happens yesterday when I passed an accident caused traffic jam. The day is hot, about 100 F and the traffic is very slow. It lasted for about 15 to 20 minutes, of course the battery had only 2 bar left. After the traffic jam, the battery is charge quickly, but I realized that the EV will not turn on, or the car has only gas engine running. I can feel the acceleration is different with only gas engine running, not as smooth as normal. I got home, turned off my car. After two hours, I tried to drive it again, it's still the same. Until this morning, it got back to normal. During the whole time, there's no any sign showing there's any problem.

Basically, when driving shortly after turning on the car (when the engine is still warming up) I often experience a 'shot' of acceleration despite not further depressing the accelerator. In other words, I'll be driving along smoothly and suddenly the car will speed up slightly by itself without me having done anything. This only occurs when the HSI is past the middle (i.e. when the engine is powering the car) and when the car has recently been switched on. It's almost as if the sensor that detects my acceleration is re-calibrating itself while I'm driving, increasing the input to the engine.
The first time it happened it was a bit of a shock and I was a little scared, however I'm used to it by now and can anticipate it happening (however it doesn't happen 100% of the time). It's nothing too serious - it probably only accelerates a couple of KMs above what I'm actually doing but still is a bit of a worry. I'll be taking it in for a service shortly and seeing what they say about.
Prius (2010-12) :: Engine Sound Is Very High While Driving Even After Enough Warming Up
I have purchased a 2010 III Prius with 73K miles last week after my 2006, everything is fine for me but I have a scary problem , the engine sound is very high while driving even after enough warming up, specially when the ECO meter reaches the PWR area or when accelerating hardly, I tried changing the engine oil with synthetic 0W-20 and the filter and the sound still the same.
Check the video attached and also note that
- Its winter here and temp is 50F.
- The car was imported from the US,
- The speed in the video in KM/h.
- I am using clean OCTANE 95 fuel.
- The video was after driving 20 Miles.
- I have latest version of Techstream with original Mongoose MFC...

I've had my nice new red Prius now for 2 1/2 weeks now, and I'm noticing a disturbing trend. Other drivers don't seem to see me! I'm not taking about drivers who don't look while changing lanes. I've now had 4 separate incidents where people have turned left RIGHT IN FRONT OF ME, causing me to slam on my brakes.
Now, prior to my Prius, I had a gray Matrix for 7 years. I would think the gray Matrix would have blended in more than the red Prius would have, but I don't think in the 7 years I had the car, I've had this many of this kind of close calls I've had in the past couple of weeks.

When I put the car in ready, the car will beep 3 times. It's like, foot on brake and press start button, then car shows ready, at the same time it goes chirp-chirp, then beep beep beep. I'm just wondering if the 3 beeps can be turned off? I didn't find any thread regarding this beep. I did find many about turning off the seat belt beep, reverse beep, etc. and I already turned off those beeps.
View 3 RepliesPrius (2010-12) :: PWR Mode - ICE Tend To Turn Off Less Often
I have clearly noticed that in PWR mode, apart from the obvious change in gas pedal response, the ICE tends not to shut down and burn fuel when releasing completely the gas pedal, especially - but no exclusively - at higher speeds (e.g. >90km/h).
In normal or ECO mode the ICE will turn off (though still turning, I know, if at "high speeds") and fuel consumption will show 0L/100km.
With PWR the engine spins and you see a fuel consumption not equal to 0.
My theory is that the engine management will be a bit more aggressive and tend to keep the ICE spinning with gas to make sure that when the gas pedal is pressed the reaction is immediate and there is no lag due to the MG1 spinning it first to turn it on. Moreover, the battery is charged more than just letting the wheels spin, but less than braking, in this way, since the engine can actively drive MG1 to generate energy for the battery (not very efficient, but after all this is PWR mode... ).
This would justify,BTW, in a more scientific way the statement on the User's Manual that says that PWR mode will tend to increase fuel consumption.
Prius (Gen 3) :: Why Does Warming Up Use So Much Gas
I'm relatively new to owning a Prius (just over a month now) and am loving it so far. I've also been lurking these forums for a while and love reading over the technical explanations of how the Prius works and all that stuff. There something that I've been curious about recently
As we all know, unless it's already been running/warmed up recently the ICE has to start up around 7 seconds after turning on the ignition (unless in EV mode). When it does, fuel consumption figures go through the roof (10-15L/100km - which equates to around 20mpg) which is obviously very high.
Now, I leave my Prius in the underground garage of my apartment complex which is basically about 20 degrees celsius (70 fahrenheit) year round, which is pretty warm. So I'm curious about a few things:
1) Why the engine has to warm up when it is stored in a warm environment anyway (a regular ICE car doesn't need to warm up - you can turn it on a drive off).
2) Why fuel consumption is so high when the engine presumably isn't actually doing anything other than idling (or is it??)
3) To improve fuel consumption, would it be better to start off in EV mode, and only switch to normal/ECO when I know I'm actually going to need the ICE such as when I enter the actual roadway (so the engine is never in use when it is not actually powering the car)? I know fuel consumption will still be higher than normal as with any car when it is first started, but wouldn't this at least save it turning on unnecessarily?
4) If it is better to do this, why does it need to 'warm up' at all?
Prius (2004-09) :: Auto Mode - Headlights Do Not Turn On In Pitch Black Night
I recently purchased an 05 prius pack 4, it has an Auto mode on the headlight switch that does not work. as in the headlights do not turn on in pitch black night... From the searches I have done it appears that the car should not have auto headlights and yet it has the switch... I dont think its canadian because it does not have DRLs... if some models DO have auto headlights then what would cause them to not work.
View 3 RepliesPrius (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.
Audi - A6 :: Engine Making Clicks When Warming Up
I have a 2006 Audi A4 with about 90,000 miles on it. Recently, the engine has been making a clicking noise when it is warming up. Once the engine is warm it stops. No, performance problems, just the sound. It got an oil change recently (I always use synthetic oil), but the sound was occuring before and after the oil change. What it could be?
View 4 RepliesPrius (2001-03) :: 2002 - Voltage Leak - Goes Into Shutting Down Mode
I have a problem with my 2002 Prius when I was driving down the highway the master warning light came on with a warning display screen appearing saying that there is a problem in the Hybrid System and then the car went into shut down mode. I had it towed to the dealer for diagnosis and an estimate. The codes read were P3000, P3004, P3125, and P3009 they did not tell me the sub-codes read. Their diagnosis was the inverter needed to be replaced. The Main battery on this car had been replacing at 140,000 and there has not been a problem since the car has been well taken care of throughout its life. Being new to working on hybrids but not cars and electronics I figured I could replace it cheaper than the dealer price of $4200. With the age of the car and high miles 175,000 I figured it would not be worth the new part price so I got a guaranteed used inverter. After replacing the inverter I still got the same problem with no change.
So I decided I would have to diagnose it myself. The car starts and runs fine and starts charging the battery right away as normal but if try to but it in reverse or drive it fails so that means the short would have to be in the transaxle. I decided to test MG1 and MG2 for shorts and I figured I would need to use a megger to do this but I did not all three winding on MG2 test shorted to ground on the 200-ohm scale on a regular ohm meter. Then after closer inspection of MG2 cables, you can see a coating of corrosion running up all three cables. So the question I have is this corrosion on the cables a common problem for 1st gen and could it be possibly just a cable issue and not MG2 and can the cables be replaced without dropping the engine and transaxle???

Sonata I45 (YF - 2011+) :: Engine / Transmission Shudder When Car Is Warming Up
My car has developed a strange engine/transmission shudder that occurs only between the temps of 32-50F. It happens when the car is still warming up, when I pull up to a red light and put my foot on the brake pedal the front end makes a vibrating/shuddering noise. You can only hear it from the inside, it sounds like something under the hood or maybe dash is vibrating.
If I shift into neutral or park it goes away. It looks like the RPM drops in drive, but it won't happen when the car is warmed up or if its colder (20F) or warmer out (50F). I recently installed a front strut bar, but I'm not sure it's responsible for causing the vibration I'm hearing.
I checked the oil level this morning, it's right at the full mark. I might try some injector cleaner but it's worth noting Hyundai recommends frequent spark plug replacement in these engines. I believe the manual states to change the spark plugs at 45K, more frequently if the car idles or is driven at slow speeds. I've also seen the 2011 manual indicate to change the plugs out at 22.5K.
Santa FE SM (2001-06) :: P0335 And P1372 - Engine Goes Into Limp Mode And Very Hard To Start
I have an issue with my 2004 2.7 Santa Fe. I keep getting fault codes P0335 and P1372, the engine then goes into limp mode and is very hard to start.
So far I have replaced the crankshaft position sensor, the MAF sensor, the spark plugs, new ignition coils and leads.
I have traced the wiring and found no shorts, the only thing which does not match the service manual is that I get 5v on the CKPS sensor wire when the ignition is on, it said it should be 0V.
The car can sometimes run for 50+miles with no issues - then stalls with codes P0335 and P1372. I have a feeling its worse when the aircon is on but cant be 100% certain/
Prius (2001-03) :: 2002 - Slipping Into Neutral Mode Suddenly When Driving
So I am getting really sick of my 02 Prius...it only has 124k miles on it. So what is happening now is that I'll be driving when all of a sudden the car slips into a neutral mode. The engine revs when I hit the accelerator but produces no power. So I pull over, throw it in Park, turn the car off, and when I restart, it is back to normal.
These are the codes I'm getting...I know this slippage is only one of my problems..
