So, my 2005 Gen II Prius went for a scheduled service on Wednesday, 70k miles, Toyota main dealer. They called and said it needed new front brake pads and disks, I was surprised but gave the go ahead. There would occasionally have been a mild squealing sound from the brakes at very low speed so I accepted the pads might need replacing, I was surprised the disks needed replacing but it hard to argue about brakes, especially as I only have the car a year (I'm the second owner and it has a full Toyota service history). It had a "major" service, new spark plugs, new front brake pads and disks.
Since collecting it I've noticed that the engine seems to kick in more often and needs higher revs. The fuel consumption seems higher, normally mid 50's MPG (imperial gallon) now 35MPG. However it hasn't been driven many miles since its been serviced so its a low distance for calculating MPG. I've also noticed that the car seems to slow more quickly without applying the brakes, a regularly driven hill that I coast down at 48kph now only gives 35kph. Also, if I drive on a flat road for a mile or 2 and coast to a stop the front brake disks feel VERY hot, way too hot to touch, drivers side more so that passenger side.
Ford F-150 (2004-2008) :: 2006 - When Shifting While Driving Down The Road And Hit 30 MPH It Goes Into Neutral
Transmission trouble on an 2006 F150 5.4 triton ... The problem I am having is when you are driving down the road once you hit 30 mph and it goes to shift into the its like it goes into neutral. It does that rill you slow back down to a lower speed then it shifts back down the transmission picks right back up till you get up to speed again, then it like it goes into neutral again. When I turn overdrive off it won't shift out of second gear. I have changed the valve body to the transmission to no success.

Ok I read about replacing a bad or ailing 12v battery (mine was original - 2007 - and resting at 10.1v) and an increase in mpg's. But I didnt expect this kind of increase!
I bought the car 9-14-12 and had been driving it very hypermilishly...lol...and getting 48mpg average.
Prius (Gen 3) Fuel :: Consumption With Speed Increase / Decrease
Since I got Prius I've noticed that driving at 50mph returns 80+mpg , 90+mpg if I let it gently glide at -1mph per 1 mile. As it gradually slows down, the mileage starts to decrease. By the time I get down to 45 mph the mileage shows around 70mpg,
I get down to 40mph, I'm only getting 50mpg. When I keep my speed between 40 and 45 I get about 52-55 mpg for the day. If I keep my speed between 45 and 50, I get 55-60mpg for the day.
Prius (Gen 3) Fuel :: Can Synthetic Tranny Fluid Increase MPG
I have the 2010 prius V with the 17in tires. I love the rims on them Vs the hubcaps on the other models.
HOwever I have read that it is hard to hypermile with the 17in rims. SO I was trying to figure out what I can do to raise that MPG up there. I have noticed that my prius does not glide well.
I have 2LBs more air in the tires then it says on the side. mine say 60LB so i have 62.
My only thought is to running Amsoil 0w30 oil and amsoil synthetic tranny fluid. I know on a regular gas car you can up your MPG at least 2 MPG or more.
Prius (Gen 3) :: Shifting In Neutral Without Turning On?
For decades, in preparation for washing our cars, I've been shifting them into neutral without starting up, and rolling them out of the garage. Typically there's a mechanical "keep it in park" lock that needs to be bypassed. Then, once you've released the parking brake, you can open the driver's door and get your car moving in "foot mode".
View 19 RepliesPrius C :: Shifting To Neutral At Red Lights Bad For Transmission?
I shift to neutral when approaching a red light when my speed is exactly at 7 mph to save on battery power that would otherwise continue to propel the car forward. Combined with proper timing, this also allows my car to come to a complete stop without the use of brakes on flat roads. Once stopped, I immediately shift back to drive to allow the battery to charge if needed and of course in preparation for the green light.
A few sites, such as Putting your car in neutral at read lights. Good or bad? (red light, manual transmission) - Automotive -Sports cars, sedans, coupes, SUVs, trucks, motorcycles, tickets, dealers, repairs, gasoline, drivers... - City-Data Forum mention that shifting from drive to neutral at red lights, then back to drive again when the lights turn green puts wear on automatic transmissions.
Given that the Prius C has CVT, will it also wear, due to such frequent D -> N -> D shifting under the circumstances described?
Gen 2 Prius (Audio/Electronics) :: 2004 - Static In AM Radio Increase Or Decrease When Driving
2004 Prius and I have lots of static in the AM radio. Some days it is worse than others mostly I am unable to listen to it. If the car is in accessory, the static in the AM radio is not there. As I drive the car the static will increase or decrease based on the proximity to the overhead wires. There are days however where the static will be hardly noticeable. I've owned the car since 2006 and have always had this issue.

Is there any harm being done by putting the car in neutral to force a coast then putting it back in "D" to charge up the battery just before coming to a stop? I've changed my driving patterns and started heavy usage of the CC and putting the car in neutral for a forced coast, but putting the car back in D just before coming to a stop or even after the down-slope coast ends. Just before going back up hill.

I'm very puzzled by how prius (2008) decides whether to use gas when I coast with neutral (I only do that if there is a long stretch of the road that is going down the hill). Same roads, same driving style, but sometimes, the gas usage goes to 0 but sometime it continue to use gas. Sometimes if you just let it in the gear a little longer or just press the gas pedal, it would go 0 after switching to neutral. There is no consistency that I can come up with the best method to get it to not to use gas and just slide using the gravity and momentum.
I can understand if it has to fill up the battery but when it uses gas at neutral, no transfer of energy among all parts. The diagram (wheel, engines, battery) shows standstill but it still uses gas. I don't have air on and turn the fan to the lowest and it doesn't make any difference.
A few conclusions I had:
It will always use a little gas at highway speed (55 to 70mph).
It appears to use gas at higher humidity (not sure but the MPG is higher when it's humid).
Prius (Gen 2) :: 2005 Car Went Into Neutral And Shut Off While Driving?
This morning on my way to work by car went into neutral and shut off while driving. The hybrid warning system light came on along with the malfunction indicator. The master warning light also came on. Also the car turned back on eventually... should I have it towed or should I drive it there?
View 13 RepliesPrius V :: 2012 Shifted Into Neutral Without Any Warning When Driving At 30mph
Three days ago our gently driven Prius with 64K miles suffered an inverter failure. I was driving at 30mph when without any warning or sign of trouble the car shifted into neutral. Soon after that I noticed that the hybrid system, power steering, and VSC warnings came on. Luckily I was in a position to stop on the side. When I shut off and tried to restart, the car was stuck in neutral. In addition to the warnings I mentioned, check engine, oil lamp, and brake system warnings also came on. I got the car towed to a dealership that diagnosed the problem to be the hybrid inverter. It was a warranty repair, but I was told that without the warranty it would have cost me around $3500.

2011 Prius II, purchased 2/2012. Driving down the highway, and the car pops itself into Neutral and the check hybrid system warning light comes on on. Had to have it towed to the closest dealership who pretty much told me it must have been my fault; I must have hit the park button driving down the road. However, about an hour prior to getting on the highway, we were driving down the road, heard a beep and started decelerating. I noticed the car had some how ended up in Neutral. Shifted it back to drive kept on our merry way. Half hour later we pull into a gas station, and the park button is not working. The only way we could get the car into park was by turning the car off (pushing the power button).
Once we got back in the car, we checked the park button and it seemed to be working again, so we took off down the highway. We only got about a mile before the car popped back into neutral, the check hybrid system light came on, and we could not keep the car in drive (by shifting it back into drive) because within one second the car would pop back into neutral. The day previous to all this, my car had just had its 5k mile maintenance.
The next day I didn't even make it out of my drive way before the car pops itself back into neutral, but no codes or anything pop up. Put it back into park and drive to work without further incidents. I bring the car to the dealership where I purchased it and they opened a ticket with Toyota drive it for 100 miles and cannot recreate the issue and Toyota is unaware of any issues with park button or the spontaneous neutral shifting. This was 2 weeks ago.
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..

Golf/GTI VI :: Possible Causes Of Increase In Fuel Economy
Wondering what could cause an increase in fuel economy. My GTI has been running at 29 +/- MPG since the day I bought it, but no higher than 30. I took it out for a ride on Sunday after I changed the front brakes Saturday. The dash tells me it's running at 34. So I filled it up and manually clocked it on a 50 mile trip. I refilled at the exact same pump - just to remove any error. And what I calculated is that the computer is right.
There is no loss of power. However, I've been fighting intermittent misfires on cyl #1 and #2. the misfire on #1 has all but gone away after finding out the coil wasn't sitting right and the spark had loosened up. I've tracked #2 down to either the injector or carbon. I'll be taking care of that next weekend.

View 8 RepliesPrius (Gen 3) Fuel :: Fuel Mileage Reduced When Driving In Rain
We gave the Prius a good workout in the rain for the first time today. Central Florida has been having serious amounts of heavy rain, creating water covered roads in our area. Normally the digital fuel mileage display shows around 55 MPG for most of our driving. However today it dropped to the upper forties very quickly.
We were running the wipers on continuous (low and med speeds), the AC (defrost) was running to keep the condensation off the windows, and the headlights were on. I wonder if the extra resistance of the water on the road also had an effect on the fuel mileage.
Even though we hit some fairly deep water and created large amounts of splash, the car tracked straight, the brakes worked well, and the power was totally uninterrupted. Other than the poor fuel milage we were impressed.
Ford Aerostar :: Running With AWD Unplugged Increase Fuel Mileage?
Winter is over and summer is here. Will running with the AWD module unplugged increase fuel mileage? Will it do any harm to the drivetrain? (Assume matched tires, good alignment and suspension).
Signed, Looking to squeeze a buck anyway I can.
