Lexus RX 2010-15 :: 2014 RX350 AWD - Brake Pad Feels Soft And Braking Is Not Very Efficient
Nov 13, 2013
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.

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.

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.

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?

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 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 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.

What is the procedure for adjusting the parking brake shoes on a 2011 Rx 350? How many clicks from tight should it be?

I have a 2013 RX 350 AWD and I'm wondering if it is equipped with hill assist. If so, how does it work?. On my other ride (Q50), the car won't roll backwards on a hill if I let go of the brake.

Just a couple of months ago, I bought a 2010 RX350 CPO, and the car seems to have developed a strange issue. When I brake and come to a stop, it sounds almost like a choo-choo train coming from the back of the car. That's the best way I can describe it. A few thumps/chugs spaced apart as I am applying the brakes to come to a stop.
What this might be? Annoying that I already need to bring this in for service, but I suppose that's what I'll need to do. Would seem like a warranty issue, but either way, the dealer better take care of this without charge.

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.

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.

Here's the short of it. 3rd time in a year the brakes on my 2005 SF (177K miles, 2.7L) have gone out.
The brake pedal is very soft and goes to the floor before braking occurs. Typical signs of a bad master cylinder.
The first time was a year ago. I bought a re-manufactured master cylinder, change it and bled the brakes. Worked like a champ and lasted 10 months.
To months ago same exact symptoms. I assume it was a bad re-man part. It's under warranty, not big deal. I do warranty exchange, bleed system, brakes return. All is good.
Less then 3 weeks later, brakes gone, same symptoms! This time I spend the difference and get a brand new OEM cylinder with reservoir. Replace, bleed, problem fixed. Brakes go out in less than a week.
I'm not leaking anywhere. Reservoir is to corect level. ABS light is NOT on. No chattering in brakes. Braking is smooth both when power brakes work and when not. No visible damage to calipers. I'm 99% sure there is no air in the system, but I'm going to try bleeding again. I have not put it up on a lift to yet to check all the lines.

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.

What is this metal on metal noise...you hear it the best around the 7-12 second mark...it is especially loud on cold start in the morning when you put the car in "drive" but don't move the car forward. It also is prevalent on hot days when you park the car outside and just start the car. The sound gets louder when you turn on the a/c during the hot day.

I have a 2001 Ford Ranger 4x4 that developed an odd problem almost two years ago that no mechanic I've taken it to has been able to find and fix, and I and my more car-savvy friends haven't had any luck with either.
About maybe 50% of the time when I sharply turn left (only left, never right) the brake pedal goes "soft" and the vehicle's braking power drops dramatically (but not entirely). Because of the sharp angle required to make this happen, and the low speeds I have to be moving at to even handle that sharp of a turn with this vehicle, this has only ever happened when I pull into a parking spot, and the vehicle still manages to come to a complete stop safely before being in danger of hitting anything. It never ever happens at any other time, and brakes like a champ normally.
I've had numerous other issues with the brakes in this vehicle in the last two years, all of which I've fixed. This one eludes me and every mechanic I've taken it to, though. I've replaced both calipers, both rotors, the brake pads, bled all four brake lines, and had the ABS control unit and ABS motor replaced.
At the time the issue first appeared, I had two damaged calipers caused by shoddy brake pads disintegrating on me (almost new, barely worn, but covered in pockmarks, looked like a Michigan road) and clogging up the calipers. That caused the vehicle to lurch to a halt with screeching tires if I so much as barely tapped the brake pedal. Replacing the calipers and brake pads fixed that issue, but did not fix the soft pedal issue when turning left. I ended up with the same screeching sudden stop problem recently when the ABS module went bad, replacing it fixed that, the brake pads and calipers are still in good condition, and replacing the ABS did not fix the soft pedal issue.

recently acquired an 07 mercury metallic with 118000 one owner and about 8 pages of maintenance all done at Lexus. car is in fantastic shape new tires, and brakes the interior still looks and feels brand new, to date I have changed the oil full synthetic 0W 20, eng and cabin air filters Toyota serviced the transmission changed the plugs with OEM off ebay. Rotated tires, rear diff fluid i couldnt find 75 / 85 anywhere so it wasn't too expensive from Toyota. the front left low beam was flickering so I replaced them I followed cucusdad instructions and it went as he mentioned about an hour per side, although I did take the opportunity to clean the inner fender well and the inside of the tires and rims.T hrough the years we have owned countless cars a couple of brand new ones although this is the first Lexus, I am very handy in the garage and have an understanding of electronics and maintenance upon reading this forum I think folks perhaps want perfect that's impossible as for mentioned this vehicle has been well maintained and obviously personally cared for.
: passanger seat heater/cool inop no light, (wifes only complaint, believe me that's saying a lot)
: aux audio input has intermediate static
: passanger rear door puddle light inop.
: slightly yellowed headlights.
: occasional vibration feels to be from front left while braking although mostly tracks straight ahead
: a very quiet car although I have read and may someday entertain some wind noise application on the triangle piece
None of these anywhere unreasonable on any car with similar miles and production date regardless the manufacture
