Corolla / Matrix 2009-13 :: 2010 Toyota LE Back Windshield Vibration When Coasting Downhill
I am a first time Toyota car owner. I bought a 2010 Toyota Corolla LE this past Saturday. It has only 42,000 miles on it, and I got a pretty decent deal on it! I'm still getting used to how the car drives, but it seems to be running great. The only thing I notice sometimes is that I am coasting downhill (not using the brakes) I notice a bit of a vibration sound coming from what sounds like the back windshield. If it keeps occurring, I might take it to the dealer for them to check it out. With my luck, the issue might not even happen though with them there.
View 4 RepliesChrysler - 300 :: Loud Clunk When Coasting Downhill
I have a 2010 Chrysler 300 Signature Series. I have taken it to 3 mechanics re: this issue but no one can find anything wrong. For work I park in a 5 story parking structure. When I'm leaving and driving our of the structure, "downhill" , I coast slowly between the turns and when I lightly put my foot on the accelerator to drive around the corners/turns there is a loud "clunk" and you can feel a little "jerk" in the car. It happens everyday but the mechanics can't reproduce the sound or the jerk. What this can be? It has happened only twice when on a flat surface, again in the parking lot, when I'm slowly coasting looking for a spot and then give it a little gas to drive forward.. the "clunk" and "jerk".
View 4 RepliesPassat (B6) :: Temperature Gauge Fluctuation While Coasting Downhill?
Typically after driving for 5 minutes or so my temp gauge is in the middle at 200f. After about 15 min of moderate 35-45 mph driving it went down a notch below the 200 mark after it had reached 200f. I've noticed this happen a few times recently. I did notice that it happens while coasting downhill. I guess i'll be taking it it to my mechanic to take a look.

During an extended drive of the new ride today, we noticed an intermittent vibration when coasting downhill around 60MPH. I popped it in neutral and the vibration disappeared completely. Also, it stayed vibration-free when placed back in Drive, without touching the gas. But as soon as throttle is applied and then you coast again, the vibration reappears.
This points to a condition that only happens when the torque converter is locked, which could be a vibration originating within the transfer case that once coupled to the engine via the locked torque converter uses the engine as a tuning fork, resulting in the vibration. The L-SB-0013-12 AWD Vibration TSB mentions an ECM recalibration, which likely changes the torque converter to unlock whenever you lift off the gas pedal. Is this correct?
I also remember reading about the other TSB, where the "magic expensive fluid" in the transfer case gets changed 3 times in rapid succession. This would address chattering clutches within the transfer case, eliminating vibration at the source vs. masking it by unlocking the torque converter.
We also noticed a misfiring sensation under light throttle conditions at around 40-50MPH. I'm wondering if this is in fact the transfer case clutch chatter issue also...since the 60k spark plug replacement has already been done.
Prius (Gen 2) :: Traction Battery SOC Went To Full Green When Coasting Downhill
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.

The following issue has been stumping every mechanic that I have talked too. We have a 1948 Chevy with a 350 ram Jet and 700 R-4 transmission. The water temp while on the road runs about 180, and up to 195 in town. The following is the problem. When coasting down a hill it will periodically quit, like the key was turned off. I have to through it in neutral, start it, and then put in drive while rolling. It never has done it at idle, on straight a ways, or up hill. No, I can’t avoid going down a long hill sometimes.

I got my grandpa's 84 ford f250 its been sitting in the barn for awhile but i drove it over to my house yesterday and it drove fine but you did have to push on the brake quite a bit but not to bad but today after school i took it for a drive around the block and i noticed that when i was going down hill just coasting i was slowing down a lot and my foot was not on the brake but when i got home my breaks were smoking pretty good but tomorrow i was going to take the front breaks off (its only the front two disk breaks doing this) and clean all the rust off them and put a little oil on the piston on the caliper that pushes on the break pads...
View 1 RepliesPrius (2010-12) :: Rubbing Noise When Coasting Particularly At Low Speeds
I 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 16 RepliesGolf VI R :: Road Noise When Coasting Only
I 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...
Golf VI R :: High Pitched Noise While Coasting To A Stop
I'm stuck in a bad situation. With my work schedule it will be literally a month until I have time to look at my car during daylight. I may be able to drop it off next week.
Anyhow, the R is making a horrendous high pitched noise while coasting to a stop. This starts at just under 30 mph and is most pronounced in neutral. Accelerating in gear stops it. It is loud inside and louder outside and there is some rough "clanking" associated with it. My guess is a belt or bearing. It is coming from the front passenger side.
Golf VI R :: Slight Whirling Noise When Coasting In Gear
So today I got to 800+ miles and when I'm coasting in gear... When I get it to the point (by the gas pedal) where the transmission is not loaded so you can slide out of gear...(you guys that understand power shifting know what I am talking about...) I hear a whirling noise.... Whoo-Whoo-Whoo- etc...I hear it sounds near the clutch (guesstimating since its near the front/dashboard)
I would have to drive it another 500 or so miles to get home. No mods, started trip with about 300 miles... Did not use cruise control.. Varied speed around 60-90 mph to keep the rpms moving since there isn't a lot of mileage here... Idk what else to say... This is really bugging me... Never launched the car... And I did search, only results I got was from other parts of the forums saying wheel bearing...

View 4 RepliesElantra MD (2010-15) :: 2013 - Hum / Buzz At Speeds Over 40 Mph
In the last two weeks, our 2013 Elantra (we have a 2014 also) has developed what I can only describe as a "hum" from the front of the car... only at speeds over 40 mph. It sounds like a electrical transformer hum/buzz. Other than the sound, the car drives and performs as always. It just went over 52k miles.
If you are going 70 mph and put the transmission in neutral, it's still there. Not a transmission sound. If you turn the A/C on and off, it's still there. Not the A/C compressor. It does not get much louder or more pronounced as speed increases, which lead me to believe it is not the alternator or a pulley, and you can't hear it when the car is parked and you rev it up.
The only other source I can think of is the electric power steering motor. I am taking it to the dealer in a few days to let them see if they can diagnose and correct this issue.

How the synergy drive is working. Why when coming down on a long down hill (mountain pass for example) the car stays at high RPM ? That usually happens when battery is charge to its MAX of 80%.

There is an intermittent buzz coming from the center console of my 2010 Prius trim level 2. It seems to be coming from the climate control system. It lasts for about three seconds, and it sounds like a fan with a bad bearing or rubbing against something else.
The buzz occurs when starting the vehicle after it has been off for several hours, and intermittently while driving (maybe once every couple of days), and exactly one minute after powering off. It began occurring a few months ago.

Prius (2010-12) :: Car Revved Up While Going Downhill With Cruise Control
Twice now, while going downhill hill (steep grade on freeway) my Prius has revved up to over 4,000 RPMs with the cruise control set at approximately 65 mph. The noise of the engine was my tipoff and I immediately had to turn the cruise control off. This just doesn't make sense to me! Seems like this could be a potential problem for those of us utilizing cruise control!!!
