Prius :: Regenerative Braking Mode
Not a Prius owner but am curious about the regenerative braking. When in regenerative braking mode, do the friction(disk) brakes stay off until regenerative braking fades or do they combine with regenerative braking (blended braking)?

I'm just wondering while under regenerative braking, is the car braking with only the front two wheels? And four wheel braking starts when the friction brakes engage? Or does the rear drum brakes always engage even though the front is braking through the electric motor?

I've been having some issues with my FM radio for a while, I had really bad static when using the rear defogger but they have since replaced my back window under warranty and that has fixed it. Though, I'm still getting static or fuzz when my foot is off the gas and I'm either coasting and/or braking. When the signal is weaker it's really bad.

I have a 2003 Prius that I have had about 4 years. It has under 80,000 miles on it and I have the Ecrostech Scanner which I have had for about 3 years. For the time I have had the Ecrostech I have noticed times when the regenerative braking was not working when I would depress the brake pedal. I understand the regen does not work from about 7 mph and below but my system often does not work even when it is above that speed. I have not been able to force it into regen. It seems to have a mind of its own as in perhaps a faulty ecu.

I took my car to the car wash and they seemed to take longer to vacuum/wash it and while driving it away, I noticed something was off. It seems like the engine is louder than normal. Before when starting the car, it would take 30 seconds to a minute before the battery/engine would come on. Then while accelerating to about 25-35 mph, then the engine would come into gear. When going on the freeway, if accelerating at a quick speed it would sound really loud. Now, it seems like instead of silent, quiet, a little louder, louder and loudest - it's moved to the next level. When starting the car, the engine starts right away and when driving away (at less than 25 mph), the engine sound like I am on the freeway and when I'm on the freeway it sound like I'm trying to gun the engine. I don't know what it could be.

for the last three days, I had the big red master warning light come up four times during normal braking, also "Problem" was displayed on the LCD where "Add fuel" is displayed when fuel is low. But no error code showed on the OBD reader. I searched found that it might be related to 12V battery which I replaced two years ago.

Golf IV / Jetta IV :: 2003 - Louder Than Normal Engine Noise
I have an 03 GTI, and recently the engine has been very loud at speeds over 25mph. There isn't any rattling, ticking or chugging sounds. It just sounds like my rpm is at 7000, when it's actually 2000.
I'll try to upload a video tonight of driving around.

over the past two weeks my 2011 GTI seems to have gotten a bit louder and has a low frequency rumble when on the lower end of the gears (DSG). Any thoughts on this? From the exterior the car doesnt seem louder to me at all. I have a stage 1 APR and everything else stock
Maybe I am going nuts but it is bugging me!
Gmc - Envoy :: Louder Exhaust Noise Than Normal When Start The Truck In Cold Weather
I have a 2003 GMC Envoy with 76000 miles on it. I heard a louder exhaust noise than normal when I start the truck in cold weather. I had it checked and was told that the exhaust system was OK but that the noise was because the motor mounts needed replacing. I have never heard of this before. Before I spend this money I wanted to see what your reply was to this question. Is it common for motor mounts to have to be replaced on this type vehicle with this mileage and age?
View 2 RepliesToyota - Sequoia :: 2004 - Louder Than Normal Road Noise Coming From Front End
I recently noticed louder than normal road noise coming from he front end of my SUV, which is right at 150K miles. I thought it was bad tires; both front ones had uneven wear. Got new ones and the noise is still there, loudest at 35-45 mph. The tire guys said I need new tie rod ends. From what little I know about those, they don't make the kind of noise I'm getting, but what do I know. I do know they are safety hazard and plan to get them fixed pronto. But will that fix the noise? I had the left side wheel bearings replaced last year, but this sound is not the same as this. Much less pronounced, but still fairly bothersome.

View 17 RepliesFord Exhaust System :: Exhaust Manifold Leaking / Louder Than Normal Knock When Accelerating
Leaking exhaust manifold? The truck has a much louder than normal "knock" when accelerating. At first I thought and had some bad fuel in the tank. I eliminated that with a full take of good fuel and some STP but the "knocking" continued. Then I thought that perhaps it wasn't firing on all cylinders but it felt like it had full power. I took it to my mechanic and he said it as a exhaust manifold leak. He said that he has never replaced the exhaust manifold but that it was a "nightmare" and expensive. He also said that it's not a safety issue but on the long run the leak would cause the truck not to pass its emission test. He said the problem was with rusted bolts that would be difficult to remove.

Just bought a 2010 Prius... Anyways... I have noticed that at steady speed (mainly higher speed) I feel a very slight power stutter (though that may not be the best word here). Not enough to change the speedometer reading, but I can feel it a little... of course I'm very sensitive to these sorts of things since it's a used car and I have only a 30 day window to identify any problems. It feels like maybe it's working out the gas:elec ratio it wants to use, which would seem normal. It's all drive-by-wire right?

I'm coming up on 20K miles and I started to notice a few months ago that when I park the car it rolls a little bit more than when it was new one year ago and rolls more than my 2004 Sienna in park with 89K miles. Is this normal wear for this type of trans? It has mostly highway miles.
View 5 RepliesPrius (2010-12) :: Traction Battery Fan Running More Than Normal?
Long time since I have posted anything here, but I noticed the fan running far more than normal here. Now the outside temp was fairly warm, but the most recent day I noticed it, the temps were only around 80-85 degrees out.
I usually don't run the AC in my car unless it is terribly hot out - so when I hear a fan running it stands out to me. It is very obvious that it is coming from the rear seat vent area.
The temps here have taken a dip (highs tomorrow are only about 70-75F), so I will keep an ear out for it to continue. Is this something to be concerned about? It is a 2010 Prius IV with about 32k miles...
Prius (2010-12) :: Green Ready Light Does Not Come On - Car Won't Start Like Normal
I have a 2010 Prius that I bought in January. No problems until this morning. Here is the situation...
I get in my car, step on the brake, mash the start button and nothing. The green ready light does not come on, no key detected does not come on, nothing. However, if I take my FOB, and place it by the start button, the ready light will come on and it will start.
I thought it could be a battery issue but, this happens with both FOBs...
Prius (2010-12) Fuel :: Difference In MPG Between B And D In Normal Driving Conditions
A large auto magazine has reviewed the Auris Hybrid (Gen III Prius drive train) while remarking that driving in 'B' gives better regen. This auto magazine also does a fuel economy evaluation and noted engine noise as a negative point for the car.
Now, how much fuel economy is affected during normal city/highway driving when you drive in 'B' rather than 'D'? And as a bonus. How much more will the engine run due to the missing regen?
