There are some NX 200t owners experiencing some uncharacteristic engine vibrations at idle or low rpms around 700-800 rpms as per this thread here, even for a 4 cylinder. How about IS 200t owners?
View 14 RepliesI have an 09 F150 4x4 with 116,000 miles on the clock. I am having an issue with moderate acceleration and felt mostly in 3rd gear. I changed the spark plugs at 106,000 miles with OEM replacements. I have had this issue since about 80,000 miles but intermittently. It seems its starting to get worse as time goes by. The problem is both cold or warm and doesn't happen all the time but now about 80%. Light acceleration is good and full acceleration is great with no issues.
Feels more like running out of fuel but not to the point of stumbling. Possible misfire that is not being detected. No check engine light lit. Tranny shifts perfect. Idles extremely smooth. I was thinking a coil problem but with no engine light, I don't want to try to guess which one. So far, this truck has been awesome and has needed nothing but tires and routine maintenance. I pull trailers consistently and this beast is not abused nor babied.
I purchased a 2011 F150 XLT 4X4 Super Crew in early January, since then I have had it into the dealership many times to correct an annoying shudder that can be seen (looking at the steering wheel) and felt as the truck accelerates. The shudder happens around 5 kph or 3 mph and then quickly disappears as you accelerate.
This is extremely annoying in stop and go traffic and is more readily felt if driving up hill. The dealer tried shims in the differential, Installed a new rear drive shaft, U joints and the last attempt was a complete rear end all to no avail.

While driving down the highway yesterday at about 65mph I went to change lanes. As I was changing lanes I gave it a little gas. About half way through the lane change truck jerked like I had just been rear ended. I immediately checked my mirrors to see if I changed lanes in front of some body. No one was around. Truck still ran the same. Everything I'be read seems like similar thing happen to others at slower speed.
5.0L ... I'm having one of those moments, you know after you do a mod to your truck and all of a sudden you notice something about your truck that could have been there all along but now you notice it as something new? Ok earlier in the week I had my exhaust resonator removed and replaced with a straight-pipe by a reputable exhaust shop. IMO the work looks to be pretty good for what it is.
That said I have always been nervous about getting exhaust work on any vehicle because it always seems like tampering with or removing the OEM plumbing for aftermarket or custom work tends to develop a vibration at some point.
So here is what I've noticed over the last couple days, when driving my truck it is extremely smooth, almost like glass. When I come to a complete stop say at a traffic light about 1-2 seconds after making the complete stop I feel this slight harmonic vibration in the steering wheel. For those of you that have an iphone it would be like having your phone bolted to the steering shaft somewhere and it on constant vibration if that makes sense.
Just to prove it only happens when I'm sitting still and idling in (D)rive I sat in my driveway with the truck idling, set the park brake and released the brake pedal holding the truck in place in (D)rive with the parking brake. No vibration, smooth as glass engine idle, as soon as I put my foot back on the brake pedal the vibration comes back. It's as if the extra draw of applying the brakes puts an extra load on some sort of accesory drive or componant under the hood and the result is this harmonic vibration.
Just so everyone knows, the vibration is very noticeable to me because I drive the truck daily, most people wouldn't pick it out if I didn't tell them first. Case in point if my wife drives the truck she can't feel it unless I tell her what to look for. There are going to be some of you that just say my truck doesn't do this and has had a smooth idle for XX,XXX miles I believe you but let me know now that I have explained exactly what to look for. Like I said for all I know it's done this since day one.
I have a feeling that the straight pipe might have been welded in slightly longer than the oem section that was removed thus putting more tention on the exhaust and engine if that makes sense, the end result being a slight vibration?? I know that manufactures put these little rubber bushings along the exhaust system on cars/ truck to absorb harmonic vibrations and for all I know my resonator might have been designed to balance out harmonic vibes in the exhaust system as well as quiet down the exhaust.
I have an issue with my new 2011 F150 FX4 super crew with 5.0. I put a Rough Country level kit on the front struts which raised it 2.5 inches and looks great. The issue is that there is a low speed knock heard on the left side and felt through to the steering wheel. The truck has been aligned to factory specs. all bolts have been tightened, the strut has been taken off to check the top mounting bolts. Nothing appears to loose. Can't find anything. Am I forgetting something. Rough Country said it can't be the kit. It has bee used for sometime with no issues.
View 14 RepliesLifting 09-13 F-150 with the two piece drive shaft. I am getting a lot of vibrations at highway speeds(55mph or higher). I have a Pro Comp 6 inch lift that was installed while I was stationed in Alaska. I have the drive shaft spacer that goes on the drive shaft at the pinion. I also have a carrier bearing drop kit from BDS that I am currently experimenting with (trying to find the sweet spot). I am at a loss though because my truck is no longer fun to drive. I drive an hour to work one way and it blows that my truck feels as though it will rattle apart. I have tried doing all the research that I can find about this issue.
View 14 RepliesLess than a week of driving the GS, the power steering suddenly seemed to stop working. After starting the car, the steering felt heavy (actually a good thing) but near impossible to turn during a standing stop.
Good thing I still have warranty. What turned out to be causing this?
I got the attached warning today on my 2010 LS600. The pedal felt a little soft after the warning. It kept popping off and on, dinging every 30-40 seconds.
I checked the brake fluid, it was full. Car has 36k
I had it towed in to Lexus and they couldn't get the warning to come back up.
Our new (got April 2014) RX350 seems to have an issue with the rubber/felt window molding getting caught between the glass and metal incorrectly. "Pinched".
View 1 RepliesJust done a five mile journey at urban speeds (20-40mph). I find that any kind of unevenness in the road is distinctly felt inside the car. Things like drain covers. I'm not sure if this is normal or a fault?
The car is a new to me 07 ls460 with air suspension, 19" wheels and fairly new Dunlop Sport tyres. I've set the car to comfort mode.
I'm thinking that I should get the suspension checked out, so if there is something wrong hopefully I can get the dealer to rectify it now. Are there any particular things to check?
I bought a set of stop tech rotors drilled and slotted. After having them on for about 5k miles I'm getting vibrations when I'm slowing down so I'm guessing they are warped already. Any better crossed drilled rotor for a decent price that won't end up like the stop tech rotors.
View 9 RepliesI test drove the sc 430 the other day, I found it very smooth and very soft ride. I noticed that when I accelerate the car feels heavy as if it lacks the torque. Is this normal?
Also, the steering felt loose at high speeds above 60mph. Is this normal?
07/ES350. Feel vibrations when the lever is on D or R? It started to vibrate a little bit on D, when the engine is hot. No lights. I noticed that when I shift in D there's no rpm rise.
View 2 RepliesI bought a gs 350 AWD about 3 weeks ago and I love it. But one thing I have been noticing is often but not every time from 0-20. I feel vibrations and almost like a skipping/jumping of the tires/car, its very soft. Is this normal?. I still have a dealer warranty of 30 days left. But its kind of far so I wanted to see what it was before I drove 2 hours to have them check it out. what this could be?
View 14 RepliesI own an LS 460 and since I had the latest recall done (ELS potential fuel pressure sensor leak) my car has been idling higher than normal and i am having a constant vibration on the steering wheel in drive mode while in a stand still.
View 5 RepliesEver since I put in my stage 2 BFI mounts I've had pretty bad vibration at 2800rpm. After over 5,000 miles, these are the symptoms:
Some times are worse than others. I will be cruising at 2800rpm and my dash will be rattling. If I lift off the throttle and re-apply it, the vibration could lessen and stop dash rattling. I think once I hit a bump while maintaining 2800 and the vibration became less severe, almost as if the bump "sync'd" whatever was vibrating.Seems to be worst when engine braking. Causes dimple dash to rattle loudly against front dash area and rear view mirror shakes...vibrates when the car is in gear or in neutral
I'm leaning towards flywheel based on what I've read. Before I replace clutch/flywheel, what could be causing it?
Also curious what labor might cost on clutch/flywheel replacement, and if the "shim" kit thing is necessary to do for a stock setup. The shop is recommending machining something in there to fix the play issues with 02m?
I have a 2006 Lincoln zephyr. 3.0l v6. With fwd. I bought the car off Craig's list, from a private owner.
When I got it, back brakes were complete crap. Looks like never changed. Put on new rotors, new pads. The car was still vibrating, and making noises from the tires. Changed front brakes and rotors. Car was jerking when braking or at really slow speeds (0-15mph) even the jerking goes away, the vibration was still there. Went to ntb today, they changed my oil, rotated tires, and balanced front tires. The jerking gradually got better, I can't say it's there at all. As for vibration, still there, and tires in back are still a little loud. Someone told me my rim is bent? That does sound like something that could be causing this?? Another thing I have noticed is that the jerking in the car and the vibration get worse after driving for a while or when my sound system has been on for a while. Another thing today, after the oil change, I got home, and noticed a clicking sound coming from the engine. Seems as if the clicking starts after the car has been driven a little bit, then stays on until you turn it off and let it sit for a while
What it could be? IS MY CAR drive able?
05 Toyota Tacoma without traction control but has ABS. A few weeks ago I noticed the brake pedal felt mushy. I had my wife step on the brakes with the engine running. I could hear a swoosh of air coming from the rear of the engine near the firewall but more towards the passenger side. I did the following tests:
With engine off pump brake pedal and it built preassure and stayed firm.
With engine RUNNING held foot on brake and turned engine off. The brake pedal moved slowly to the floor.
Check the check valve in the brake booster and its good.
So, I replaced the Brake booster, bleed the air out of the master cylinder and bleed the brakes. Now it feels great for about the first 20min of driving but then goes soft again. and I'm still getting the swoosh of air escaping from somewhere in the same place as before.
I'm wondering if I have a vacuum leak somewhere before it goes into the brake booster? the connection is good where the vacuum hose comes from the engine to the brake booster. OR should I replaced the master cylinder?
Strange Vibrations From Engine (Possibly?) While Riding Brakes In Slow Traffic. I tried to search but didn't come up with much that was similar.
View 2 RepliesTiguan 2.0 TSI 2009... Lately I am experiencing occasional engine vibrations, especially once the engine is cold, but do come even after engine has warmed up. Sometime even at highway speed, i could feel the vibration, but no effect on engine pull or acceleration. There is no noticeable engine misfiring. On few occasions, one starting, the engine does not pick the rpm and rattles with EPS, Oil and CHG light remaining on. A little press on the accelerator and engine gets to normal idle. The diagnostic computer does not show any fault. The local VW dealer after an expensive trouble shooting has 'diagnosed' POSSIBLE low fuel pump pressure, faulty ignition coils and ignition leads, and a heavy bill for replacements.
