Lexus RX 2010-15 :: Acceleration Noise At Low Speed


Dec 31, 2014

I just purchased a new 2015 RX 350. As I accelerate from a stop at normal speed it sounds loud to me. The loudness disappears at 30 mph or so. I have a 2001 RX 300 that does not do this. I like (a lot) the new 350, but am surprised that the engine noise is louder that a 15 year old RX.

Lexus GX 2010+ :: Brake Squeaking Noise At Low Rolling Speed

Bought my 2013 GX460 in Dec, 2012...approaching 3000 miles now. Everything is great, however, I have been hearing braking squeaking noise consistently under these conditions:

1) Low speed braking, such as approaching traffic light.
2) Low speed braking in cold morning (40 degree).
3) Low rolling speed, driving in parking garage

No noise under high speed braking.

Is this normal? I googled a little, saying that such noise is the result of high performance brake they put on the GX460.

Lexus RX 2010-15 :: Thumping Noise When Braking At Low Speed On 2013 RX350

Have noticed a thumping noise when braking at a Low speed on my 2013 RX 350. Brought it to the attention of my Lexus service mgr at the 5000 mile service. He did a test ride and heard the same thumping sound. He then test drove another 2013 RX at the dealership which made the same noise.

Lexus RX 2010-15 :: Squeaking Noise From Dashboard When Driving Over Rough Road Surfaces And Speed Bumps

I have an RX 450H and noticed that there is a squeaking sound coming from the dashboard. I looked at other posts where people were experiencing similar issues and noticed one post where someone had a GS 450H and fixed this issue by adding felt between the dashboard and the windscreen.

I would like to know whether this method works 100% and whether I can apply this method to the RX 450H. The noise becomes worse when it is cold and especially when the car is being driven over rough road surfaces and speed bumps.

Lexus LS 2007+ :: LS460 AWD Jerking On Low Speed When Driving Without Any Acceleration

My new LS460 AWD 2008 is jerking on 60-80KPH(37-50)MPH, when you driving without any acceleration.

I have only 900km on odometer. And it's started jerking from 0. I gave my to Lexus for a test. They tested it over 7 days, and now they are saying nothing is wrong with it. And it's normal for AWD version.( WHAT???? )

They have one more new AWD 2008 and it has the same jerking issue.

Santa Fe (CM - 2007-12) :: 2009 - Speed Related Noise On Acceleration And Hills

I took my 09 6 cyl. AWD Santa Fe Ltd. into the dealership this morning because of a whoop whoop whoop noise when accelerating normally or maintaining speed on a grade. A bit like a helicopter sound. The frequency of the noise increases with speed and seems to come from the front driver's side. I thought it might be a wheel bearing.

$2000+ later I have new tires, a 4 wheel alignment, new rotors and pads fore and aft, a new tie rod end and a car that goes whoop whoop whoop when I accelerate or climb a hill.

The car has 125,000 km. (78,000 mi.) on it and has been very well maintained. Detonation maybe?

I have a 2010 with about 166k miles. I am getting a slight hesitation at slight acceleration or constant speed. It does not matter if it's on highway or freeway speeds. Now I am not sure if this in junction with me changing the PCV valve, cleaning the EGR pipe, or cleaning the TB for carbon recently. It started happening a week after it though.

Lexus SC430 :: 2010 - Hesitation On Acceleration From A Stop

As I have experienced hesitation on acceleration from a stop, I found a TSB # L-SB-0154-10, that addresses this condition for the 2010 SC430. It was issued in 12/1/2010. I am not sure if it would apply to any other years. The TSB entails re-flashing he PCM with updated software.

Lexus GX 2010+ :: Vibration When Turning At Low Speed

I have a switchback in my driveway, which it pretty steep. I've noticed that when I'm turning right going uphill on that switchback, with some accelerator applied to get up the hill, I get a vibration through the steering column and floor.

Not super-noticeable, but noticeable. I've also tried it on the flat. If I turn the steering wheel maybe a little more than halfway towards the "stop" at the very limit and then accelerate a little bit, the vibration is there too.

I don't think my old land cruiser or my current fj exhibit this vibration. Don't know if it would be originating from the transmission or cv joints. Doesn't seem completely right in an "off-road" designed vehicle.

Lexus RX 2010-15 :: 2014 RX350 - Vibration At Slow Acceleration

I bought a 6,000 mile RX back in december and notice the vibration at slow acceleration.

It sounds like it's coming from the rear of the vehicle. It stops when it gets up to speed. I looked for anything lose and don't notice anything underneath.

I'm not too impressed with my local dealer so far to have them look at it. It sounds as if something is loose inside the muffler. It does not vibrate upon rapid acceleration.

Lexus RX 2010-15 :: RX350 Engine Brake And Acceleration Hesitation

I just purchased an l/certified 2013 RX 350 (34K miles) this past weekend. I did not notice these issues on my test drive. I've started to notice that when taking my foot off the gas pedal (while not resting near the break pedal) the vehicle goes through a series of easy coasts and then some resistance (as if using an engine as break on a truck with a manual t,) then returning to a smooth easy coast.

I've also noticed that when accelerating at a slow speed from stop (I'm in traffic) there is a bit of a hesitation, like turbo lag, yet this has no turbo. The lag seems to be there even if I want to accelerate aggressively.

I hate to get tied up with a dealer service department already.... "Cant duplicate," or "that is normal operation," or "Computer codes check out." Looking for reinforcing information so I don't have to take it in once a month for an unknown amount of time.

Of our three other cars (2015 Prius, 2002 Nissan Altima, and (pre-tran fail) 2002 honda odyssey) none experience anything like this.

Our household is dumping a 2002 honda odyssey for repeated transmission failures never covered with goodwill. All service was at a h dealership and manufacturer schedule was followed. I'm already sensitive to the manufacturer/dealer relationship.

Lexus RX 2010-15 :: Instability While Turning Right - Car Went Out Of Control At A Very Low Speed

My wife drives a 2013 RX 350 AWD. During this winter, when she turned right (once from a standstill, once without standstill), the car went out of control at a very low speed. The vehicle has around 12000 miles on the odometer. The Lexus dealer could not replicate it. He said it might have been snow on the wheels. I too experienced it once and was very scared to use her car after that.

Here is what happens: Turned right at slow speed, suddenly the car sort of accelerates goes left, right and kind of rocks and then after 15 feet or so steadies itself. My wife has reduced her own usage of the car due to the freight she got twice.

Lexus RX 2010-15 :: Vibration At High Speed And While Braking

2010 RX 350 NAP ... Brand New and OEM where it would apply : Tires (Conti's LX20s)

Brakes / Rotors (had same shake before replacing and did not improve after replacement but maybe I am dealing with a bad caliper here)
Tie Rod Ends
Stab Links
Lower Control Arm Ball Joint

None of which have solved a vibration issue thus far. Strut feels solid and the corner push test had the car settle out in less than 2 bounces.

If car has sat a while the driver front (where the issue lies) feels like a imbalanced tire/bent rim (rotated the wheels just to be sure it didn't follow the wheel/tire) or like a broken belt. The tires are almost brand new and only put them on because I was trying to eliminate the point of issue.

When braking, a light touch to the brake pedal makes a almost light clank sound (like weight shift is causing the clank or perhaps a sign of a bad caliper (although pad wear looks even but didn't have rotors rechecked but even with brand new rotors it was there so I don't feel it's a warped rotor plus the vibration is there even when not applying the brakes.

There is only one control arm and the bushing didn't look cracked beyond the normal surface cracking I have seen on most rubber bushing. The upper support is from the strut so perhaps a bad strut or maybe strut support/cap/bearing?

At a total loss as the local garages cannot find anything wrong. My thought was a bad wheel bearing, although there is not any grinding sound that you typically hear when a hub is going bad.

Could also be the CV Joint but not sure how to tell if that really issue the issue unless I replace all the other parts first (hub, caliper, strut/support/bearing).

Lexus GX 2010+ :: 2016 - Car Goes Bouncy On Highway Speed

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.

Elantra MD (2010-15) :: Clunking Noise / Knock On Acceleration

For the last few weeks (about a month) I have been experiencing a clunking noise/ knock on acceleration coming from either in front of my feet or below my feet (drivers side) ONLY on acceleration and only then from a full stop. I can also feel the clunk as well which leads me to believe it is a transmission mount.....maybe an engine mount. I am taking her to the dealer after work today. we had some very cold weather and I was hoping it was just ice but yesterday and today were well above zero and it is still there and it is EVERY time I accelerate. Which is a somewhat good thing since I will be able to replicate the problem for Hyundai.....

Lexus RX 2010-15 :: 2014 RX350 - No Speed Control Going Downhill With CC At All

I have no speed control going downhill with CC at all. Dealer says this is normal. I've had two other Lexus GS models and when going downhill they would downshift and use the engine to maintain a constant speed. My Mercedes does the same thing when going downhill it downshifts to maintain a relatively constant speed. Is this normal with the RX? if so, what a disappointment.
