Lexus GX 2010+ :: 2016 - Car Goes Bouncy On Highway Speed
Dec 18, 2015
The ride is okay until I reach concrete (grey colored) pavement on a highway going at highway speeds. Then it gets very bouncy, where even the st wheel vibrates. I can even hear some kind of noise coming from the back as it's bouncing on the highway. As soon as the pavement changes, this stops and it goes back to a comfortable ride. I also have some weird intermittent crunching type of noise that I hear while turning. But that is rare. There are about 700 miles on this car now.

I got my 2005 jetta gli used with about 41000 mi on it. Ever since i've had it, when i accelerate on the highway at 50 mph or faster, the car almost feels bouncy throughout, what that is.

I am wondering where I might find the approximate rpms for being in 5th and 6th at 70 miles and hour. I am wondering if it is shifting into 6th as the mileage is significantly lower than the AVG shown in the display.

I have a 2005 GX470 with 96,000 miles. Yesterday, while going on a 500 mile road trip the car stalled suddenly while traveling about 75mph on the interstate. It would start surging and then just stall completely. I pulled over.. Let the car sit for a minute and then it started right back up with no trouble. It did this to me 4 times on the trip about 80-100 miles between issues. The last time it was while accelerating hard up hill. All other electrical functions.. Radio, lights, etc... continued to work fine. I don't recall the cel ever coming on and even if it did it wasn't on when it restarts. It was 100 degrees out.
I'm on vacation so wanted to get it checked put before we head home but curious on thoughts of what it might be? I was thinking clogged fuel filter or MAS but the fact that it restarts right up after stalling makes me ink it might be more of an electrical issue.

Find the ride on the 2013 Elantra kinda bouncy ?....I thought it might be the cheaper OEM tires, but after running winter tires, the ride was still kinda skippy/bouncy over rougher roads.....

I got off the highway today and was at a very long light, but enough time to feel my car making slight jerking movements and i saw the car raise a little over an inch.

Have a 2007 F250 6.0 diesel with the standard issues including misfire at highway speed. Assume the bulletproof kit also cures the stiction problem? in reviewing the threads and looking at the vendors, references are made to fixing the oil cooler issue, egr issue, etc., but no one addresses stiction issue directly.

Front end noise over bumps / Bouncy fuel gauge....Lets see how it goes. Brought the car in for a few things to have fixed under my CPO warranty.

Maybe it's because I've been away for two weeks and out of the RC, but when I drove for the first time in a while the car seems like it's noticeably bouncy on relatively smooth roads.
Again it could be my break from driving it. I mostly drive on Sport+ mode.

I have a 2007 f350 scsb with the 6.0 that has 131k miles on it... I bought it in December at 125k and since I first got it I've noticed a lot of steering play at highway speeds only... Basically 60 mph and up... I have a hard time switching lanes and passing because it's very unpredictable just how the truck will behave... It feels like the steering is loose but also slightly delayed and when I make slight adjustments it feels like the truck overcorrects itself... Could this be a steering box issue? A power steering issue?

Since I got my car back from the dealership after changing the rear shock this summer, I can feel a vibration in the car at highway speed. After the shock were replaced the car steering wheel was out of balance and pulling one side. After they attempt to align the car about 5 times it got a little bit better. Then I found out that they had an accident with my car and tried to hide it: [URL] ....
I suspect the tie rod may have been damaged so that could explain the steering issue. It also seems to have gotten worse over time. I'm trying to figure out the possible cause, if directly related to the tie rod damage or indirectly as if the tie rod damage could have caused uneven tire wear and then causing the vibration over time. I've attached some pictures, the 2 first are from the front passenger side, the 2 last from the front driver side. My tire are the Michelin pilot and this thread seems to suggest those tire might be hard to align properly: [URL] ....
I'm due for my winter tire change soon and see if thing gets better, I'll get them balanced too. I'll check at the same time for control arms/shock damage. But still, I would like some feedback and see if those tread wear are normal and hopefully get to the root of the problem (the outer edge on the tire in the back are much less damaged).

Noticed the lights jittery or bouncy when you go over bumps or imperfections on the roads. This cannot be right?

I have a 2006 f250 and the heater will blow cold air unless you are driving in like highway conditions. If you stop or drive slow it blows cold air only. What is causing this???

I just bought a 2007 ls460 with 100k miles on the car love the vehicle but I have 2 issues with it first wind noise which I will get fix after dealing with the car bouncy ride. When I first got the vehicle i didn't notice the bouncy ride it happens when going fast on freeway 60+mph over bumpy and uneven pavements. It would bounce up and down and wobble side to side like crazy where it is scary that I will lose control if I don't hold on to the steering wheel hard.
So I replace all four shocks still no fix. My mechanic said my control arms bushing are bad. So I had all 8 front control arms replaced with OEM parts. That made a big difference on the driving and handling. It doesn't bonce as much as it did but it still bounce a little and wobbles side to side but not as much. I feel like the car is not suppose to feel this way only happens on freeway at high speed over bumps. Do I need to replace my rear control arms as well for the car to not bounce and wobble.
My mechanic said there are 10 total arms in the rear 5 each side. Will this work for my ride? Or do I need to replace new springs? I don't want to spend more money than I already have on it. I did a 4 wheel alignment and my specs in front are good but my left rear camber is -2.6 degree toe is 0.16 and my right rear is -2.0 degree toe 0.10 alignment guy said that if i change my rear control arm it might support the camber.

So I found an 03 gx one owner and only 56k Miles on it. Nice truck. I noticed right away that the rear suspension feels hard and bouncy. When I adjust the height it does work but seems to take a bit. In the Low setting feels like it is on the bump stops. Not sure where to start, sounds like the level sensors can be an issue, so I will have a look at them. Feels like it is just going to the top height to me thus making the ride really stiff. I climbed onto the rear bumper and tried to bounce the truck and it is like a rock. Like the bags are over inflated.

I've been noticing a tremendous amount of wind noise going 70+ on the highway. My car only has 18K over a course of 4 years. The only the possible think I can think is the seals have dried because of standing in the sun for so long at school and then not getting garaged when I get home, my mom's and dad's car get priority. It used to be garaged when it was my moms. I don't think the sun can dry out the seals so quickly.

I have a 1997 Oldsmobile 88 (174K miles, owned only by my father-in-law and then me) with which I am experiencing a hesitation problem from time to time at highway speed. My mechanic has taken the car on several highway test drives throughout the last two days, and he has been unable to reproduce the problem. Furthermore, he has done a full diagnostic test and found no problems with the fuel system, ignition system, or anything else.
Here are the conditions under which the problem occurs:
---Attempting to accelerate gradually at highway speed (usually from 50-60 mph), but WITHOUT pushing the gas pedal down so far as to cause the transmission to downshift
---Engine fully warmed up (temp gauge at 200 F or just below)
---Occurs more often when I have been driving for at least 1-2 hours
The condition is as follows:
---Car lurches/surges noticeably and does not accelerate
---Speedometer needle reflects the lurching by fluctuating up and down about 1 to 2 mph
---Accelerates well if I step down hard enough to cause the transmission to downshift, or stops surging if I lift off the gas pedal
---NO Check Engine light at any time
Some history on the car and corrective actions taken:
---June 2009: My mother-in-law was driving the car about 6 hours into our trip and it consistently hesitated between 50 and 55 mph with the Check Engine light on for the last 30 miles or so of our trip. The next day, we took the car to the dealer where my in-laws had their cars serviced (note the past tense here), where they told us that "there's probably something wrong inside the transmission" and suggested that we replace the transmission with a new one. This transmission is the second new one the car has had (replaced the first time at 95K miles), meaning that this transmission had less than 80K miles at the time. We took the car to a local shop at the referral of a friend, and this mechanic suggested we try flushing the transmission fluid and replacing the filter to see if that would fix the problem before we started talking about replacing the whole transmission. This worked, and we were glad that we did not have to get rid of the car. Did not notice any more problems with this for over a year.
---May 2010: Experienced engine misfire, had spark plug wires replaced. Problem solved.
---March 2011: First noticed my current problem. Had fuel filter replaced (it was probably a little overdue) and had the mechanics do a fuel system cleaning.
---April 2011: Problem still occurs.
---Had throttle body thoroughly cleaned, which fixed a slight sticking in the gas pedal.
---Replaced spark plugs myself. Car running more smoothly overall, but the hesitation still occurs.
---Inspected all three ignition coil packs myself. Top coil pack had some rust on the poles, which caused the resistance to measure as zero. Cleaned most of the rust off the poles, after which all three packs bench tested at 6.23 (with 20000 ohm setting on multimeter). Car runs even more smoothly overall, but hesitation persists.
At this point, my mechanic and I are both stumped as to what could be causing the hesitation problem. My only thought right now is to try replacing the one coil pack that had rust on it, since a pack with a fault I can see may have others inside that I can't see, and maybe something like this is flaking out on an intermittent basis.
