Ford Excursion :: 2003 - Vibration When Braking In OD At Higher Speeds

2003 7.3 Excursion, 130k, stock suspension with newer bushings, etc.

Vibration when braking at higher speeds - not felt as pulses through brake pedal or shimmy through steering wheel - rather, a "body" vibration. Stops as soon as the TC unlocks. Being a diesel I can't tap the brake to allow it to unlock like on the gasser 4R100's - its locked until it shifts down into 3rd. Turning off OD puts it into 3rd but locks TC (no way to "single out" TC). Only felt when braking in OD (though I haven't tried running up to highway speeds with OD off/trans in 3rd) - braking is completely smooth at all other times/gears/speeds and at all braking force (light, mod, heavy).

Front and rear pads are good with even wear and sufficient material, lugs evenly torqued, tires good/balanced, no sign of a stuck caliper or rotor warping, MM manual hubs unlocked. No driveshaft carrier on the Ex's, just a regular two joint shaft with recent Neapco Gold u-joints, no slip yoke play. Trans filter replaced 4k miles ago, 6 +/- qts DexIII/Merc exchanged when I did the filter, fluid smelt and looked fine. Transfer case fluid changed about 5k miles ago. Factory LSD rear diff not serviced recently but fluid suctioned from fill hole looks acceptable.

I'm afraid that something is going on with torque converter/shudder but I don't get any shudder or slip under acceleration or at any other time and gear shifts are smooth. I know that the 4R100's can be sketchy, especially with 130k, but want to get suggestions before digging into it. I've also got a very slow hydroboost leak/weep but the power steering fluid is properly filled. Steering is smooth and proper, brake pedal movement is normal so I assume there is no air in the lines.

Subaru - B9-tribeca :: Pulsation Happens When Braking And Gets More Severe When Stop From Higher Speeds

I change my own pads as a good lifetime warranty with free replacement from Autozone is great!

But with the Tribeca... I changed the front rotors just like all my other cars over the years.. and now there is pretty severe pulsation when trying to brake... I've checked the rotors and pad replacement twice now and all looks perfect.

I searched this pulsation issue and saw on a Jaquar site that you can ruin the ABS on some cars when you don't drain excess fluid as you push the piston back to install then new thicker pads..

Is this an issue for B9? I don't see it anywhere... I'm ready to bring it in the shop.. the pulsation ONLY happens when braking and gets more severe when stopping from progressively higher speeds...

Prius (2010-12) :: Regen Braking Force Less At Higher Speeds At Over 45 MPH Or 70 KMPH

I have noticed recently that I seem to be getting less regen braking force than I used to. Particularly noticeable at higher speeds at over 45MPH or 70 KMPH. The regen seems to have very little effect now until I have slowed down. I seem to have to use much more brake than I remember recently. And by the way the battery in not nearly fully charged....Regen does come on but seems to have very little slowing power....

Elantra XD (2001-06) :: Engine Whirring At Higher Speeds / Vibration When Stopped And Braking

I have two simultaneous problems with my 2005 Elantra (automatic transmission). I don't know if the problems are related or not, or if they are alarming or not.

Background on the car: timing belt and water pump replaced in 2010; four tires new in 2010; oil changes every 5000 km.

The first is that my engine is making this 'whirring' sound when I approach 80km/hr. It's not high-pitched, but more of a droning noise. Having read around the forums, I see that Elantras commonly make funny engine noise, but this is fairly new to my car (145,000 kms) and definitely not there at all when idling or at low, city-street speeds.

Additionally, I have a weird vibrating noise coming from the front left of the car only when I am dead stopped and the brakes are fully depressed. It doesn't make this sound in park, and I don't hear it until the car has come to a complete stop; there is no odd noise while slowing down.

Hyundai - Elantra :: 2007 - Sounds Rough At Higher Speeds

My husband and I noticed that my Hyundai Elantra (2007) sounded rough when running over 60mph. The car has 61,000 miles on it and is due for an oil change, a radiator flush, and a fuel filter replacement. My manual says that the platinum coated (versus iridium coated) spark plugs would need to be replaced at 60K miles. I was told that the car would run rough at lower speeds if it was the spark plugs.

Passat (B6) :: Hard Downshift When Decelerating From Higher Speeds

So I've had my B6 7 months now with no major problems (other than a blown head light bulb, which was repaired under warranty) - until now....

So when I'm decelerating from higher speeds (55mph +)...say for a stop light or to turn....around 30mph....my car occasionally shifts down hard. Not enough to make me stop driving and call a tow truck but definitely enough to make me to notice.

It's only when shifting down and it's just started in the past month or so. Before that the car has performed beautifully...shifting like silk. My car is a 2007, auto 2.0T with almost 20k (had 4k when I bought it). It happens when I decel slow or have to stop real fast. It seems like there's no rhyme or reason to it.

Passat (B6) :: High Idle / Transmission Is Sluggish And Rough Downshifting

The notorious 3.6 high idle has haunted me for over a year now. When it first started happening, I thought it was a temporary thing. It has been happening for a year now and the stealership has not been able to diagnose it. It has started happening more frequently now, no matter the weather. The idle overall is just rough. I place the car in neutral sometimes at a red light because the vibration and idel is so rough. The transmission is sluggish, and as i come to a stop sometimes, i can feel the rough downshifts it makes from gear to gear. And just today, after I picked up the car from the dealership from a failed diagnosis of the high rev problem, my parking sensors stopped working. When the system turns on(car in Reverse), there is a steady beep even while there is nothing behind me. Even as the car is moving(below 10mph) the car makes three beeps, every five seconds or so. I do not know what to do. I have a feeling that even if I take it to a different stealership, I will get the same results.

Passat (B6) :: 2008 - Engine Was Cutting Out At Higher Speeds - No Compression

Initially I brought the car in for repair because the engine was cuting out at higher speeds so they replaced all 4 coil packs and did an oil change.

After 50+miles of driving it was taken home. Later on we tried to start the car and it wouldn't start. The car has power and it cranks.

We then bring it back to the shop and they say there is no compression. I suspect conventional oil was used.

Would the wrong oil cause my problems? 2008 VW Passat Turbo...

Passat (B6) :: Extremely Rough Downshifting In Sport Mode - Transmission Valve?

When driving in Sport Mode I have a violent down shift as the car slows and heads into second gear from third. It doesn't seem to matter if I am going 40 miles an hour around town or 70 miles an hour coming off the freeway. There has been a few times where the jerk is so hard that seatbelt tensioner tightens. Is this a normal aggressive function of the sport setting, or is this something else? Perhaps related to the transmission valve/hard second gear shift issue?

Passat (B7) :: Ticking Noise When Turning At Higher Speeds - ABS Or Traction Control?

I've been hearing a faint but rapid ticking noise when taking faster exit/clover-leaft style turns (usually ~40mph). I think it's the ABS or traction control on the verge of kicking in because if I push it a little harder I do get the flashing traction control light on the dash, but the ticking is happening before that light comes on.

I'll ask the dealer when I do the courtesy 30 day inspection... I'm at the end of the 2nd week of ownership with 200 miles right now, so I'm still getting used to the car. (2013 Passat TDI SEL). Loving the 40+ mpg on my rush hour commute!

I did a search and didn't find anything on the B7 forum that might explain this noise. I don't think it's a CV joint since the car is new, it happens when going around these style turns either way and only seems to happen at higher speeds. I suspect it's just that the traction control is sensitive (or maybe I haven't scrubbed the tires enough yet to get good contact).

Passat (B6) :: 2.0 Auto Thuds When Auto Downshifting After A Long Drive At Highways Speeds

My 07 AT 2.0 has a weird problem - when auto downshifting after a long drive at highways speeds, the whole car thuds. This happens after driving about 20 miles or so at 60MPH+. 5 or 10 miles are not a problem.

What happens is that when it slips down into 2nd, it sounds like something jams (no grinding). The force/feeling is similar to running into something at a slow speed - like bumping a car while parking.

If I slip into Tip and downshift manually, it doesn't happen. Outside of this the car has 22K miles and drives great.

Passat (B5) :: Slight Squeal When Braking From Moderate Speeds (20 Mph And Under)

I have started to hear a slight (but getting louder) squeal from my brakes when I am braking from moderate speeds (20 mph and under). I know that the car had new stock brakes put on it less than a year ago. What I should do about it?

Stock 1.8T 5spd 2001 discs all around.

Passat (B5) :: 2000 - Pedal Is Buzzing At Feet When Braking From Slow Speeds

I'm experiencing a weird problem with my Passat (2000 TDi 110), where the brake pedal is buzzing at my feet when braking from slow speeds. If I am doing around 5-10mph and lightly apply the brakes, it sometimes buzzes in the peddle and I can't apply full pressure (this can be tricky when behind another car!), but if I take my foot off the pedal or wait around 3 seconds, the buzz and pressure restriction goes and then I end up braking quite sharp as the pressure releases. The buzz is quite audiable and can be heard by others in the car and sounds quite electronic. Pads and Discs are fine, they will need replacing soon, but this issue has been going on for a while, so I don't think it's related to them.

Golf V R32 :: Braking Malfunction When Downshifting

When I downshift while braking, especially in the lower gears, it feels like the brake pedal depresses further. And why does this happen?

Also, do people find you get cleaner downshifts if you have the gas pressed down a little, or do you downshift while braking, or just downshift without either?

Passat (B6) :: Rough Braking And Code P0299

Elantra MD (2010-15) :: Downshifting From 5th Gear To 1st While Braking

The downshifting while braking is very obvious during braking, I can literally feel the gearshifts going down from 5th Gear to 1st as I brake. I have driven a wide range of cars but haven't experienced this earlier. Is there any modification that can be done or added to change this and make it smoother like usual cars?

Touareg :: Downshifting Does Not Provide Engine Braking

I don't know if this will be corrected by the next Tranny Flash (since the current flash wasn't applicable for my 61xxx VIN and engine code), but I have noticed that whenever I opt for Tiptronic, and downshift, my Treg seems to speed up first. I don't notice any significant engine braking until I apply the brake.

Passat (B6) :: Higher Pitch Of Faster Turning Engine / Car Idling At Higher RPM At Stop

Sometimes I will stop at a light and my idling rpm will go from 600 (usual rate she idles at) to about 950. While this may seem inconsequential in the grand scheme of things, it's noticeable enough that it seems like the car wants to go. It'll lead me to depress the brake more. You can also hear the higher pitch of the faster turning engine (it is a 50% increase in speed). This will happen at random times so I have not been able to pinpoint if it is caused by a particular driving style. ECM for this?
