2004 toyota prius hybrid power loss on uphill grades
We are expriencing a pulsating power loss as we drive in uphill grade driving conditions. We have drove these roads many times in the past (years) without any problems. The pulsating comes from us feathering the gas pedal to keep up our speed. It reminds me of when a gas powered cars fuel pump is starting to fail and as you step on the gas it starts to bog down. The battery indicator (bars) during these times, drops to only a few bars. We have no warning indicators that come on during these times and the screen showing the engine and battery output seem to be working. We have owned this car since it was new. This problem just started to happen.
I'm looking for the manual for troubleshooting help, but that has not showed up yet. Thank You, email@example.com

Re: 2004 toyota prius hybrid power loss on uphill grades
Since you did not mention that there are any warning lights on at the dash, I must advise you of the following: Prius vehicles are VERY PICKY when it comes to the proper weight of oil. That being said, and if you have the wrong weight oil in it, expect problems. Easy way to check this: Take off the tube going to the throttle body at the front of the engine. Open the throttle plate & look down into the intake...Do you see any oil laying there, in puddles? If so, you def have incorrect oil in the engine. This will NOT det a DTC code, and it WILL give you your condition.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Hello, There is absolutely nothing wrong with your car. It's actually keeping you safe! If the outside ambient temperature is +37F or lower, your car knows this and gives a warning for possible black ice conditions. Lots of people wonder the same thing, next time it shows the warning, note the outside temp to see if it's below +37F.
Hello, lets test that BMW M5 ABS braking system, OK. First, drive down a street
with no traffic. Speed up to 30 to 40 MPH. Then slam on your brakes hard, if the
brake petal is pulsating and there a noise like clunk,clunk,clunk,clunk noise.
Your BMW ABS is working. If not, then the BMW ABS isn't working.
ABS system and what it does to your BMW. All it amount to is it doesn't lock
up the braking system. It just applied the brake and release in micro seconds.
This keep the vehicle from sliding side ways on wet roads, snowy roads, icy
roads or even on dry roads. In other words, it keeps the front of the BMW in a
If your BMW ABS isn't do this, you'll need to have the ABS braking system
could be a few things, this must be a hybrid, 1st make sure all the tires are inflated properly, the tire pressure will be stamped on the side of the tire, also if it a hybrid it has regentavebreaking system which means the more you use the brakes the more power is returned to the battery system, also the higher the alcohol content in the fuel you buy the lower the fuel mileage, what i recommend is to fill the car with the best fuel you can get NO ALCOHOL so you can get a base line on the fuel mileage then try other brands and grades to see which ones give you the best mileage.
The AWD means All Wheel Drive. Sort of the same as a 4 wheel drive. All the wheels have power at the same time. In a slippery road condition, all tires/wheels can loose traction at the same time causing loose of control - which would be normal. AWD does not mean traction all the time in snow and ice. It still has to be driven with caution and respect to road conditions. Hope this helps.
The basic explanation of these gears are as follows. 2up/2wd is a basic two wheel drive setting where the vehicle will react as a rear wheel drive. In this gear the transmission will only distribute power to the two rear wheels(best for all around driving with clear road conditions and will give the best fuel efficiency). 4up/4wd is a high speed four wheel drive setting. in this gear the transmission will always distribute power to all four wheels and will allow you to drive at higher rates of speed( good for poor road conditions when ice and wet roads are a moderate risk). 4dwn/4lo is a low gear four wheel drive setting where again the transmission will distribute power to all four wheels but will limit you to a low rate of speed(good for really rough roads and severe weather or very poor traction conditions). auto gear selection is basically a all wheel drive setting, where the transmission will use a primary setting of rear wheel drive gearing until the vehicle slips or looses traction on one of the drive traction. as soon as the transmission detects a difference in wheel speed between the two rear wheels, at which time the transmission locks up the front differential turning itself into a four wheel drive, until the wheels have regained traction and remain spinning at the same speed for a set amount of time, at which time it will then unlock the front differential at return to a rear wheel drive setting. this is a good all around gear but will cause you to get slightly less mpg/kpg then a 2up/2wd gear would. i hope this helps
I'm not aware of any such problems, and puzzled as to why you suspect the transaxle but one thing is certain: you have a very technologically advanced car with many highly interconnected systems controlled by complicated firmware/software. It has many benefits, but one of the trade-offs is that you're effectively tied to visiting Toyota dealers when things go wrong and the vehicle absolutely MUST be maintained according to manufacturer specifications.
Hybrid drive is still very new and is an immature technology. Sorry, but you simply won't find the kind of useful and comprehensive answer you need anywhere other than at a Toyota dealer. My company has run a fleet of assorted Toyota and Honda hybrids since they were first introduced and so it's my experience that any problems you experience will rapidly escalate and become far more difficult and costly to diagnose and fix. This is true enough of any modern vehicle, but hybrids have far less fault tolerance.
If it helps, many baffling and apparently major faults have often turned out to be caused by simple things like faulty sensors, solenoids and software bugs. Poor advice and guessing just turns them into money-pits.
In short, get your car to Toyota asap and find out exactly what's wrong. You can then decide what to do next.
some other garages can diagnose this problem m8 but its not wise as there not used to the system there gonna charge about 70pound to look at it, how old is the car? it might still be under warrenty, it should not have done to much damage though.
