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.

View 20 Replies2012 Prius with 10K miles.
One of the features I really like over the '06 Prius is the ability of the cruise control to hold the set speed on downhills (until the battery fills up and it switches to compression braking "B" mode, but that's a different topic).
After taking it in for the 10K mile service, it no longer engages regenerative braking on downhills with cruise control set. This is on the same hills where previously it would hold speed.
Did Toyota do a software upgrade that disables this feature?
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.
View 14 RepliesI 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.
View 10 RepliesI 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.
View 6 RepliesReplacing 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.
View 3 RepliesI 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.
View 4 RepliesThe cruise control on my 2013 works as I expected.
However the cruise control on my 2016 Sonata does not.
When driving at highway speeds (65 to 70 mph) in cruise control and the shifter set on "D" (drive) the transmission will down shift to 4th speed whenever I go down hill.
This might be intentional as a way to keep the car from exceeding the set speed, but I have never heard of this and it would seem to place more wear an tear on the transmissions.
Do the down shifting is engineered in or if it is a service problem that I need to have addressed...
Twice now, while going downhill hill (steep grade on freeway) my Prius has revved up to over 4,000 RPMs with the cruise control set at approximately 65 mph. The noise of the engine was my tipoff and I immediately had to turn the cruise control off. This just doesn't make sense to me! Seems like this could be a potential problem for those of us utilizing cruise control!!!
View 15 RepliesMy 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.
Curiosity question. I've noticed that on a downhill of a couple miles, especially in "braking" mode or with the cruise control on, the motor/generator and engine are used to keep the speed down and the battery gets charged to the very top quite quickly. That's good!
On a really long downhill, will the motor/generator still be used for braking and the excess electricity discarded to keep from overcharging the battery?

I have 2 messages showing up in the message center / control panel. I have taken the truck to the dealership and we cannot recreate them while the truck is at the dealership. How it can be resolved.
2013 Ford Superduty Platinum : 33,800 miles and the truck is stock
Messages : service traction control / Downhill decent control fault
This will happen just driving down the road or just after starting the truck and taking off.
It has happened towing my work trailer and also not having the trailer connected to the truck.
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.
