I noticed yesterday that sometimes when I'm driving down a street which is slightly downhill and the ICE is off and I'm coasting that the EV light is sometimes off even when my foot
View 1 RepliesI had my 2006 Prius (108k miles) shipped (on the back of a flatbed) from Los Angeles to Seattle in mid-October, and I noticed a drop of MPG pretty quickly. I went from 46mpg to now 34mpg over the last month, over 3 tanks of gas.
I have Goodyear tires, but I don't know the make of them (I remember they were 'High Efficiency' or something, meant for fuel economy) and I checked the PSI and it was 36 front, 34 rear. At first I thought it must be the tires but they seemed fine.
Then I thought it was the cold weather, but really the change in temperature wasn't very dramatic (until last week) as I was on the beach in LA where it was typically 65 and the past month in Seattle it would be typically 50-55 (this past week notwithstanding!).
I have noticed something about my 2010 Prius. Lately when I am driving the car for about an hour, the engine slowly reduces RPMs (based on sound) when I take my foot off the gas. The MPG indicator slowly goes from near zero to 100. Like VERY slowly. And that is just street driving below 45 mph. The car has almost 60k miles. Tires are correct and in very good shape.

View 14 RepliesSo I was driving my car about a week ago when it decided to "die" on me for about 2 seconds. I was coasting in neutral (tiptronic) to a red light when the car's engine light popped on and the car just bogged down hard. I threw the car into drive and the problem went away immediately. I haven't had the problem since then, but I'm also not allowing the car to coast in neutral anymore.
I was thinking about bringing the car in to have them read the computer but is this something that they would be able to trace back or would I be out the 90 bucks for nothing? I have absolutely no clue what this could be.
My 2008 Prius had a front quarter panel replaced after my wife back in to a fire hydrant.The body work looks fine , no issue there, but now when the car is coasting with the gas engine off you can hear a humming sound that was not there before the repair.Also it does,nt seem to be recharging the hybrid battery at the same rate.My thought is maybe the body shop caused some damage to MG1 by spinning the front tires on a emision testing machine or rollers.Does special precautions would have to be used when testing wheel clearances after a quarter panel replacement on a hybrid? Would a body shop need to do this ?
View 2 RepliesYesterday when driving at high elevation and extremely cold temperature I heard and felt a pulsing from rear of my car when coasting or idling.
View 5 RepliesI just had an oil change done on our 2010. Also of note, I've just switched the winter tires over to summer tires - done myself. So here's the issue. When coasting, particularly at low speeds, a rubbing noise can be heard issuing from the front right somewhere. The noise goes as the rpms go and seems to go away when either braking or accelerating. I'm not sure if it's present at high speeds due to road noise which would overwhelm it.
View 4 RepliesSymptom: A vibration that feels somewhat like a bouncing tire
Cause: Coasting in Drive (Applying the gas at all stops the vibration, putting the car in Neutral also stops the vibration)
Noticed the barely audible (with good ears) high-pitched sound that emanates from the car when you let off the throttle enough to prevent any charge or discharge bar from showing? It goes away if you completely release the throttle or if you press the throttle a tad bit more.
View 19 RepliesDriving my car (2001 Jetta Wolfsburg w/ 1.8T) to work yesterday and all of a sudden the airbag light comes on... As I was almost to my exit I continued another 500 yards. The ABS/and brake light come on as well and the car dies as I coast to the side of the road. I would not start so I had my spouse bring the trailer and another battery to see if it would start up. It started up and we loaded onto the trailer.
Took the battery to Napa and they said battery was bad. Today I buy another battery and the voltage of the battery not running is 12.2V and with the car running the alternator to battery voltage is the same. How do I know if the voltage regulator is bad or the diode or something internally in the alternator? Also how to I get the airbag light reset?
So our car has performed flawlessly since 2005/135K miles. Still getting 55 mpg in the display in the summer, 45 mpg in the winter. Only issue is traction battery SOC quickly goes to full green when coasting downhill, and 1 or 2 purple bars when climbing. In Colorado, this happens a lot. Within a mile or so coasting downhill the SOC is full green. Question is: should I replace the traction battery? Is there any harm to continuing to experience this behavior? When full green, I realize I am using friction braking over regen braking, have actually felt the crossover from regen to the pads, as the SOC goes full green.
View 4 RepliesI am getting a light clicking from my rear Axel when coasting at a slow speed. It could be clicking at any speed but my car is to loud to hear it going down the road. I don't have more details than this. What to look for ?
View 15 RepliesI'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.
View 5 RepliesI had whining from the engine compartment when I am coasting and accelerating, much noiser than in the past. I had been getting a C1310 code along with C1253 , C1241 and C1300, but I changed out the Anti Skid ECU and these went away. However I still get the red triangle of death VSC and ABS lights on after driving on the highway for about 10 minutes at speeds over 65. So I then got P0A2B 250 codes, Drive motor A temperature sensor. After it rested a while and I restarted the car, all but the red triangle would go out. After two more starts the Red triangle went away too. This happened for a few weeks, until one day after a trip, the car just stopped. Would not start at all, no ready light went on. Testing gave me a P0AA6 526 code, Hybrid Battery Voltage System Isolation Fault. Now I know the 526 could be multiple faults but with the whining and the P0A2B, I am thinking the transaxle is the smoking gun.
View 14 RepliesLast week as I was returning home I had a strange event in my Prius. I was coasting at about 30 mph when I heard a very faint pop sound a bit like a balloon breaking. It sounded like it came from the right rear area of the car. Afterwards I thought I detected a very faint chemical smell. Could this have been something involving the HV battery?
View 10 RepliesWhen I go out to do errands around town (I live right in town) I get horrendous gas mileage. Now, I understand gas mileage is high at the beginning of a trip, but for this long and this high and under these circumstances? I'm getting ABOVE 10l/100km when I have 80% charge available (for americans, that's disgustingly high MPG like, pick-up truck high), AND my foot is completely off the gas. Literally, coasting, or braking, and I'm still sucking up gas. What the heck?
Is this just because it takes a certain amount of time for the engine to run no matter what or something? I still don't see any reason for me to be eating up all that gas when my foot isn't even on the gas AND most importantly, I have charge available. Feels pointless for me to use my car for what I use it for 70% of the time, which is for quick errands around town at low speeds. Thought the prius was suppose to be a superstar for this kind of thing.
New 2012 GX 460 in 01/2012. While GX is coasting between 55 mph and 70 mph, noticeable "whine" from vehicle. (Sounds like the whine from snow tires, but that happens all of the time in a previous vehicle.) Noise disappears when the accelerator is engaged. Been like this from day #1 and now at 10k miles. Dealer seems perplexed; has said at delivery and at 5k service that it is the tires. Bridgestone dealer says "not our tires."
View 14 RepliesI just bought a 2013 Golf R and have been driving around with some kind of road noise since the day I got it. The sound occurs when coasting only, and is most audible above 55mph. It is best described as a mid-high-pitched hum or drone, kind of like a much quieter semi (when you drive next to them on the highway).
I took the car in to a VW dealer and they were able to hear the sound on a test drive but were unable to diagnose the source. They rotated tires, checked all bearings/hubs, and eventually called VW to find out that it is a "characteristic of the vehicle" and that VW is aware of it and nothing more.
Aside form the noise there are absolutely no issues with the car and it only has about 8k miles on it...
So I'm used to the vibration coasting down from 110-115mph or so, I would mitigate it by applying light throttle. Recently it started coasting in the 75-80 range, then 70-80, and now it does it just plain cruising in that range as well. Nothing below 65, and nothing above 80 (coasting, cruising, or under load).
It's definitely a mechanical vibration, tires are fine, wheels are fine, wheel bearings are new... Thinking driveline u-joints? Don't have the money to throw parts at it unless they're the fix. I've consulted Christina's analysis chart and this is the only thing that makes sense so far.
No other symptoms anywhere else except those ranges. U-joints are, as far as I know, OEM originals. 276k miles seems like a hell of a life for them, especially with the abuse they've seen in the past 75,000.
I need to crawl under and give things a shake and wiggle, current condition is unknown. Left for a road trip to meet the wife's ex so he can have his time with his son, and the X was so bad at the aforementioned speeds that we turned around and swapped vehicles. It was worse this morning than it's ever been and I wasn't risking catastrophic failure with a zero emergency fund.
I have a 1993 Caprice that was running great. The engine purred. We hD it sitting over the winter not driving it at all. Now when we go to drive it there is noise. It purs when you are just coasting, but when you put your foot on the gas there is a loud noise. This noise was not there before we let it sit. What can I do to quiet the engine again?
