I'm still getting the occasional "slam" as I decelerate from freeway speeds as the trans downshifts from 4-3. Service writer says VW is aware of the problem and are working on a TCM reflash.
View 1 RepliesI can hear a drone at freeway speeds coming from the engine compartment of my 99 Passat 1.8. I don't know whether this is normal, but it seems like the down pipe has a resonance/vibration. How to reduce this? Test pipe? Header wrap? Or is there something wrong that I have this buzzing?

Possibly a mount?
I have about 25K miles on tires that are expected to last for 60K miles. The tred is fine. But I have experienced occasional serious shaking of the car when going at high speeds. Not every time. And it has only happened when I am alone in the car (of course did not happen with mechanic in the car). My mechanic says I need an alignment and new tires, claiming that by being out of alignment the tires are ruined. Says it is heat and road conditions that cause the effect and there is steel belt damage within at least one of the tires. Curiously, the car does not do the classic out-of-alignment thing of pulling to one side. Not at all. Is it an alignment and tire issue or something else? The car has 175,000 miles on it and otherwise run great!
View 6 RepliesI have a weird vibration only at freeway speeds. It's a vibration that lasts 3 seconds but are consistently 2-3 seconds apart. It's a very suttle vibration and can be felt at my feet and slightly on the wheel. My passengers can feel it if I mention it. The key thing about the vibration it's starts and goes away the starts and goes away?
View 14 RepliesJust bought certified preowned 2009 Prius from dealer. Never had one before. I did test drive it for 20 minutes before purchase. But on the way home from buying it today I noticed a constant and subtle "stammer," on the freeway at speeds between 50 and 80 mph, like as if the car was very slightly and frequently shifting in speed even though the accelerator was in a constant spot and the road was flat. I watched as the display constantly shifted, like many many times per minute, where and how power was being generated/used.
View 12 RepliesI have a 2000 6.8L V10 Ex, and I'm currently working through the last thing on my "to fix" list. The truck has 37" tires (Nitto Mud Grapplers), and at freeway speeds the speedometer is off by 10mph. If it reads 60mph, I'm really going about 70mph.
I thought the solution was to order an SCT flash tuner, so I purchased one with tunes from 5startuning:
**1. SCT 7015 - X4 Flash Device with Choice of 5 Star Tuning Custom Tunes - 5 Star Tuning
I choose the correct Revs per mile for my tire (560), but the speedo is STILL 10mph off at 70mph.
No changes that I made to the tire size or axle ratio made any difference. It always read the same amount off. The SCT X4 flash tuner wasnt able to change the speedo on the 2000 Ex's.

My question is this: If both of those tuners plug into the exact same port, and use the same parameters, why is it my X4 tuner can't change the speedo, yet this other tuner is able to? It doesn't make any sense to me. If the X4 truly cannot change the speedo of certain model years, there should really be a disclaimer about it. Feels like a bit of a rip off since the only reason I purchased it in the first place was to correct my speedo...
I have a 2010 Prius no frills model with 5500 miles on it. I've started hearing a noise that sounds like loud burst of radio static. I hear it with the radio off or on. It's very intermittent, but seems to occur only at freeway speeds. Seems to be coming from underneath the shifter or underneath the dash in the same area.
View 2 RepliesI have a 2000 5.2 ltr. Dodge Ram Van. Only in overdrive, only with the cruise on, there is a slight hesitation at freeway speeds every few seconds. The Chrysler dealer said it was the overdrive clutches going bad, to the tune of trans rebuild. Guess what? It didn't fix it.
View 2 RepliesI have a 2002 4Runner that has recently developed a vibration at freeway speeds. I purchased new tires about two months before the vibration started. I have been back to the place where I bought my tires and the assure me that they are balanced.
I have been dealing with this problem for the past couple of months and have been getting nowhere. When I took my 4Runner into the dealership to get the lower ball joint replaced I spoke with the service folks about the vibration problem and all I got in response was "we've never heard of that before".
Have excessive cabin wind noise in your Gen 6 when travelling Freeway speeds. I know there would be some noise but when passengers mention it and we talk louder than normal then i think its an issue. It is kinda loud now...
View 2 Replies2011 Camry LE with what I would call a mushy or sloppy feel to the steering. It is most noticeable at freeway speeds and requires an almost constant driver input to maintain the car in my lane with slight corrections back and forth right and left. This is fatiguing on long drives. It feels like there is too much power steering assist at higher speeds, although an independent mechanic said he didn't think it has variable assist power steering. There is no pulling in one direction. Alignment has been checked and it's ok, and tires are balanced and properly inflated.
Strong wind or large trucks passing me cause me to struggle to maintain the car in it's lane. Toyota dealer mechanics and the Toyota rep checked it and gave me the "drives as designed" answer and that there is nothing wrong with it. I had an independent mechanic look it over and he said there is nothing wrong and that there is nothing that can be done to change the feel of the steering. It is hydraulic steering and not the electronic power steering. I have test driven other Camrys as well as Corollas and other makes of cars and they all drive with a more sure feel to the steering and I just want my Camry to drive like that.
2007 Hyundai Elantra, gets this noise/squeak when around freeway speeds.
I took this short video, squeaking starts around half way in: Video - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting
This is a really annoying noise .
OK so here's the deal. Driving around town @ lower speeds I've yet to have this problem. When driving at freeway speeds seems like between 1/4 tank & reserve all of a sudden the power just drops off . I mean like the ignition has been turned off. No throttle response .. nothing..... just begins coasting & dropping speed. When throttle is depressed... totally dead. This lasts for about 5-10 seconds then after coasting & looking where to pull off the highway all of a sudden the engine kicks back in like nothing ever happened. Where to look for Jetta MK 4 18T Fuel supply problem??
View 4 RepliesGot a strange one here. 1995 Buick Park Avenue, supercharged 3800, 159K miles... an older car, but an unmolested one. A little over a week ago I began to notice an occasional miss when cruising along at highway speeds, along with a slightly rougher idle. Both the fuel filter and the plugs/wires predated my ownership of the car (a little more than 6 months); so seeing no obvious culprit, I replaced them and hoped for improvement.
Unfortunately, neither had any impact. The missing continued to become more noticeable. It was never present under acceleration. Most of it was like a split-second long version of "bucking" that could be observed while cruising at lower (<2000) RPMs. It was also very noticeable at idle. Eventually a code was set: P0341, camshaft sensor issue. If the story had ended there, it would have been just another night in the garage. But it didn't.
As I was noticing the aforementioned symptom increase, I also noticed my voltmeter would occasionally "twitch" in the downward direction. Eventually I had an incident where I came to a stoplight... transmission in Drive, foot on brake, gauge dropped to around 10-11v. It returned to 14v momentarily, but dropped back down, held there for several seconds, returned, etc. No particular rhyme or rhythm. Of course my first guess was that the alternator was failing; a separate problem from the other.
I checked all the relevant connections (at the battery, at the alternator, etc), and cleaned them for good measure. All were tight, relatively clean, and the cables showed no resistance on the ohmmeter. It happened that I had another correct alternator on hand (used/working pull), so I swapped it in. No change. I reinstalled the original and was back where I started.
On my most recent drive, I noticed both issues had become very noticeable. The drop in voltage was happening at nearly every stop, and the missing was happening a few times per minute while coasting along. There seemed to be some correlation between the missing and voltage fluctuating, but it wasn't absolute.
I decided to attack the voltage issue again. Re-checked all the cables; same result as before (all OK). Looked all over the car for possible bad grounds, loose connections, or other visible problems, but found none. My next thought was to run a jumper from B+ to the voltage regulator's Sense input (have seen issues there on more than a few older vehicles) - but after reading that this car uses the PCM as the voltage regulator, I didn't proceed.
Just to be certain I'm going to have the alternator tested by the local auto parts store. But I suspect it'll pass.
My 2002 Toyota Highlander burned up to a quart of oil very 300 miles when on a recent long distance freeway trip. It must be burning it out the back as there is no drip. Clearly, there is a leak, but why only when driving on long freeway trips? Can this be due to pressure build-up and a clogged PCV?
View 9 RepliesI have a 2001 F150 4x4 supercrew XLT 4.6 with 150,000 miles. I have a few things happening in the truck, and although it is still running for now, I would like to get ahead of this before something catastrophic happens, and I don't know if everything is related, or everything is falling apart separately.
1. I have been noticing a burning smell coming from under the hood after driving, every time I drive, but no noticeable leaks, and oil level is fine. I have seen light smoke coming from the exhaust but inconsistently. A mechanic said it was probably the valve cover seals leaking to the manifold, but I would think there would eventually be less oil on the dipstick?
2. When on the gas, over 2200 RPMish, the air and AC switches to defrost. It seems like a vacuum line leak somewhere, but can't find it.
3. Generally, the truck seems sluggish, sometimes unwilling to shift gears or accelerate at freeway speeds. Not sure if its the transmission going out again (had it replaced at 125000), or spark plugs?
I have a 2006 F250 Lariat CC FX4. I bought the truck with 68,000 miles about 3 months ago. This is my first 4WD and I'm wondering if I need shocks.
I know how to check on a car but this suspension is too stiff to push down a corner so how do you test? Or do you just go by the age? At freeway speeds when I hit a bump I get a bit of a shudder that makes me wonder if the axle is hopping.
If I were to replace them are the Rancho shocks OK for a replacement? I will spend very little time off road and mostly use this truck for boat towing and hope to buy a travel trailer down the road.
165k miles 4x4 6 speed, bone stock unmolested
Slowly progressing problem over 6 months. Occasional miss at highway speeds uphill has progressed to bucking and jerking during even gentle acceleration attempts.
I hadn't got my cam sensor recall done but no change after that procedure completed yesterday. Oil recently changed as well.
I have a torque pro but it never finds any fault codes even though 'service engine' light comes on sporadically. I'm not sure I'm operating it properly but it at least reads rpm when its running.
I'm contemplating the hutch mod but I'd like to have an official diagnosis beforehand if its possible in my case.
Why I am smelling coolant? I have a 2004 6.0 SD.It generally happens when accelerating up to freeway speeds or passing cars, Medium to hard acceleration and the smell is strong and will go away after a few min. The obvious thing is to check for a leak but I haven’t seen any.
View 14 RepliesFor no apparent reason, my 2001.5's 1.8T, with less than 67,000 mi on it, suddenly began "hesitating" when power was called for. I first noticed this while the car was climbing steeply one side of the (very tall) Newport Bridge. I could feel the occasional deceleration as I tried to maintain constant vehicle speed (with and without using cruise control), but could see no change in vehicle speed or engine rmp on either the speedometer or tachometer. It felt as if fuel flow to the engine had decreased a bit for a second or two and then returned. This occurs consistently and is most noticeable when accelerating from a dead stop as I'm climbing through the gears (manual transmission). Also, there's no apparent turbo boost. Are these classic symptoms of a failed turbocharger (or something else)?
