Lexus RX 2010-15 :: 2014 RX350 - Vibration At Slow Acceleration
Apr 7, 2015
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.

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.

I have a 2011 RX350 and like car for the most part. Something strange I have noticed is that the gas pedal seams to have some little vibration when I am pressing it smoothly. My foot is constant on the gas pedal maybe 1/4 of the way down and it doesn't feel smooth like other vehicles. I have a 2014 lex IS250 and it doesn't have that vibration. Also had a 2004 RX330 and it did not have that vibration. It is a slight vibration that ruins the luxury driving experience.

My 2010 RX 350 only has 35K miles and I've been feeling that the smoothness in the ride has really deteriorated in the last several months. So much so, that even though I could have squeezed another 5K or so out of my tires, I bought a new set...OEM Michelin Latitude Tour HP. I can't say the ride has improved at all. Today, I brought it to the Lexus dealer for a brake inspection, because I was getting a slight vibration in the wheel when braking. Front brake job was needed. I was given a 2013 RX 350 as a loaner. The ride in that car is so much smoother. Should I be questioning the suspension or some other issue that would improve the ride?

Having issue with seat belt buckle vibration, passenger side, when the vehicle speed is between 40-50 miles/hr ? It feels like an exhaust vibration transferred through the floor connection of the seat belt. How can I get rid of it ? The vibration feels like a cell phone set on vibrating and is very annoying for the passenger.

I am on my third RX now with my 2014 RX350. Previous to this car I had a 2007 RX400H which I loved. I find this new car much noisier when on pavement than my RX400H. Noticed the interior noise on the 2014 to be quite loud. I compared to my wifes Mercedes ML350 also a 2014 too and it's much louder.

I have a 2014 RX350 and the brake pedal rattles when I use it. It seems to be loose at the pivot point way up under that dash but I can't get to it. It seems to have excessive movement side to side otherwise it works as it should.

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.

Replacing license plate bulb on a 3rd gen rx? I tried taking off the interior lining on the rear hatch but no luck. There's access covers for taillight & reverse, but none for license plate light. I also tried "popping" out the plate light cover right above the license plate... don't think they are designed to be popped out.

I just got my new 2014 RX350 a few weeks ago. After these weeks drive, I feel the Brake is kind of soft and unsensitive.
When I braking, the first part of the brake pad feels soft and the braking is not very efficient, until I push a lot of the brake pad, the braking becomes confident and efficient.
I used to drive my 2006 Nissan altima , and feels the brake pad is very sensitive. My new lexus makes me a little bit unconfident when following a car in a short distance.

New owner of 2014-RX350. I have figured out most stuff simply using the owners manual (go figure), but this one continues to stump me, as I have repeated the procedure right out of the owners manual without success.
Manual states to have only one fob or card present, car in park, "ignition on" position (I interpret this as two pushes to the ignition switch), push desired memory button and hold while pushing either lock or unlock button till chime sounds. I get the chime. But when I lock the door, wait a minute, and unlock the door by touching the handle, the car unlocks just fine, but seat does nothing. When I manually push L2 (in my case), the seat does indeed move into position. But I cannot for the life of me get this function to work.

Is there a way to increase the volume of the buzz sound when locking the door with the remote? It has been bothering me for a while. Every time I lock the door with a remote as I am walking away from the car, I need to listen very carefully for the almost inaudible buzz sound so I am sure the door is locked. I searched in the settings but didn't find where it can be changed.
BTW, it is a 2014 RX350.

Can I disable unlocking of all the doors when I open the rear hatch from the outside? I figured out that if I use my fob, the doors does not unlock.

Weird thing yesterday, noticed a rotational tick sound coming from the right rear wheel during slow backing up with the windows down. Sounded like debris stuck between the dust shield and the rotor. Had that tinny sound. Anyway, no dealer around in the town I was at. Closest is over two hours away and not in the direction of home which was four hours away.
I was visiting friends, and decided to jack the truck up and pull the wheel off and clear whatever debris was stuck in there. Pulled the wheel and didn't see anything. Rotated the hub and could still hear the noise. I pulled the caliper next and made sure nothing was in there. There wasn't. Ok, must be in behind the disc in the parking brake shoe area and making contact with the dust shield. I pulled the caliper mount and then the rotor. Still didn't see any debris or anything foreign. What I did see was a bunch of metal filings on the inner side of the brake shoes all around the backing plate. Also a fair amount of metal filings in the drum portion of the rotor.
Rotated the hub again, and noticed the noise coming from the retaining pin cap on the rear most shoe. It was rubbing against the backside of the hub. As the hub rotated the cap spun and made noise as the spring gave way and turned. This made sense for the noise and the metal filings. The cap was still in place and the pin was not being touched yet by the back of the hub. I reassembled it all and decided the further drive home was not going cause more harm than what was already done.
Dropped off at my local dealer this morning and explained the above. The technician confirmed it as well, and ordered the a new retaining pin. Some how it got out of tolerance and caused itself to be longer than it should have. The tolerance appeared close from the front side shoe that was not rubbing.

I took my 2011 Lariat in for first service and reported that it sometimes tries to accelerate on its own during slowdown from high speed, eg when coming off a freeway ramp, rpms go up and vehicle wants to speed up rather than slow down. (sounds like something a Toyota would do!)
Dealer says its a known problem with 5.0L and performed a supposed fix per "TSB 11-8-9, 5.0L ENGINE BRAKING PERFORMANCE DURING LOW SPEED COAST DOWN," essentially a PCM reflash.
Happened once in a parking lot...thought the floormat was stuck on the accelerator but the pedal was clear.

For the past 4/5 weeks my truck vibrates when i brake at slow speed ex. Driving out of a parking spot, slightly braking no matter if i go forward, reverse, turn or go straight it'll vibrate, sometimes very lightly, but usually it's very noticeable, can be compared to the clutch pack issue with these trucks. I had the clutchpacks in the rear diff. replaced at 160k ,after that it drove very smooth but that only lasted 20/30k.
So when turning it'll vibrate at about 15/20 km/h, but that's because of them crappy clutch packs

I have a 4motion Automatic Tiguan 2011. It always had a tiny acceleration lag which I believe is quite normal. But lately, our Tiguan developed a that-doesn't-sound-right symptom. I feel the acceleration gap is much longer now, the engine makes quite a bit of noise but the car hesitates to go, and it gets a bit worse on uphills. It had a transfer box leak that was fixed 3-4 months ago.
It sounds like a transmission problem to me. Is there something wrong with the power train?

I have a 2010 Prius Pkg 5 with around 71xxx miles. I usually drive it like a regular car on eco mode and get around 38mpg average but recently I've changed my style of driving where I accelerate to the desired speed limit, let go of the gas, then reapply and keep the mpg meter in between the middle eco line and before the pwr band. I've been able to average 44mpg this way, which is great!
However, what I've begin to notice now is that say if I'm traveling at say around 45mph and let go of the gas and re-apply, the engine starts to shudder as if it's not getting enough gas. Why this is happening? I also need new tires (215/45/17) but that doesn't have anything to do with this. I've owned this car since 30xxx miles and haven't done anything other than put gas and change the oil at the dealerships. Could putting 87 octane gas with up to10% ethanol have any effect on this?

I find it a little concerning that I can actually drive off in our RX350 without the key fob in it. I know there is a warning on the dash, but that doesn't stop someone from stealing it. May be a park lock out would be a better solution.
