Lexus ES 2013+ :: 2016 - Adding All Speed Dynamic Radar Cruise Control
Feb 21, 2016
I brought my new 2016 ES350 last month and I love the car
.
One feature I am missing is all speed DRCC. In my car the cruise disengage at 25mph. I see the feature I am looking for is available in some other higher models and the Lexus technology video's says 'when your call is equipped with all speed DRCC'.
I would like to know if it's possible to add this feature in my 2016 ES by any means? I searched and couldn't find any other useful info.

Symptom: Dynamic Radar Cruise Control (DRCC) fails to slow down the vehicle, (with slowing down or stopped vehicle in front) when DISPlay button on the steering wheel is pressed several times after DRCC is set.
The issue was tested several times with my 2015 GS350 AWD, Canadian model. Maybe it only applies to me, or perhaps it applies to all models with Lexus Dynamic Radar Cruise Control equipped.
Tests: Speed up, turn on main cruise control, and start DRCC when there's no vehicle in front, set to desired cruise speed, set the distance range control to desired range. Now, press the DISPlay button on the handle a few times (5-6, maybe flip through the whole menus, long and short presses. You are all set. Now, drive up to a stopped vehicle or moving vehicle closing to a stop (or slowing down). 4 to 5 out of 10 times, I found out that the DRCC does not sense the vehicle in front, not applying the necessary brake. The screen (where vehicle in front is pictured) shows the vehicle in front at times, other times, The sensing screen is just left blank. Still, the vehicle is on cruise mode and keeps the set speed, however the it acts like a regular cruise control, NOT the dynamic radar one when approaching a slowing down vehicle. At times, pre-collision warning beeps if the vehicle in too close, still no brake. When I says 4 to 5 out of 10 times, the other 5 to 6 out of 10 times, it works beautifully as it is suppsed to. (i.e. slowing the vehicle accordingly)
I tested several times at the 45km/h (30 miles/h), just enough to get the DRCC on, day and night, the vehicle failed to slow down in front of a slowing down vehicle (or a stopped vehicle). At times, the pre-collision warning beeps when the vehicle is at a close distance. I am suspecting that when DISPLAY button is pressed during Dynamic Radar Cruise Control is ON, DRCC fails to work as it should. Not every time, but several times.
I first experienced this at a highway moving at 100km (62 miles) and almost rear ended the vehicle in front if I didn't quicky changed the lane, and warning beep alerted.
I know I shouldn't rely on these technology and I do not, however, if this is a software issue, it should be corrected.
I've been trying to find out when exactly this issue would happen and record on my phone, but I couldn't. I was able to record one occasion on my cell phone, however, it was at night and the vehicle in front was actually a parked vehicle with the rear lights off. (although I think it should've still worked). I am still trying to come up with exact occasion for this issue and get it on video. (Speed/DRCC ON timing/AC/Lights/etc)

Is the drcc on the 2013 full-speed range or is it partial speed range? (will it bring the car to a stop or does it only work above certain speeds?)

I was driving at 65mph and decided to coast and slow my speed to 50mph, as there is congested traffic ahead. I know the radar will adjust my speed according but I wanted a slower set speed anyway. I held the cruise control lever in its downward position (thinking it was going to cause the car to coast and slow) Oh Oh! This thing is applying the brakes hard! I instinctively press the gas but it kept decelerating, no affects at all except the tranny downshifting or engine revving. I couldn't tell which, the radio was loud and it happened so quickly.
Moral to the story- I guess I should have read the owners manual. The manual say every .75 second the lever is held down the cars speed will be dropped 5 mph. My question is- since the car was applying the brakes and I overreacted and pressed the accelerator at the same time, was there a possibility of damaging a component? I know these cars are engineered extremely well.

I'm looking for a fully loaded AWD LS460 and haven't run across many with the dynamic cruise option. Was that option rarely chosen? It's time to add a second Lexus to the garage.

So yesterday we had a bit of snow north of the city. I was driving on the highway and suddenly my cruise control deactivated and I got a message to clean the radar. Then I had PCM flash every second or so. I was really frustrated because this is a MINIMAL amount of snow and it's not even below zero. I'm hoping that this isn't an ongoing issue with these cars? Any solution besides getting out of the car and cleaning it? When I got home I saw that there was a layer of ice on the Lexus logo on the front of the car.....

I recently purchased a 2014 GS350 (CPO). One thing I've noticed is the cruise control has about plus/minus 2 miles per hour variance from its set speed as the car progresses over road inclines. This happens in Eco, Normal, and Sport modes.
I know +/- 2 mph doesn't sound like much, but I thought that the car would hold its set speed without much variance. Even with a manual transmission, my previous car (2006 Audi A4) kept its set speed better than the GS.

I have a 2013 Avalon Hybrid and am having trouble while using the cruise control. The "sensor needs cleaning" goes off although the sensor has been cleaned several times. Also, the sensor sometimes doesn't register a vehicle in front of me. The Avalon has been looked over by the dealer (several times), the sensor was replaced but the problem persists. Because it works periodically, it's difficult to diagnose a problem. Also, the PCS warning goes off periodically. Not sure if that's a related problem. It has gone off while driving through an intersection with traffic sensors (not consistently).

My 1999 SD was originally a Work Truck without cruise. I'd like to add cruise of some sort (factory or after market), but also trying to keep the cost and difficulty factors low.
Have any of you SD drivers ever done this and if so, what you went through?

The latest addition to the driveway (2012 F250 XL 6.2) is getting ready to be geared up for it's tour of duty. The one thing that was on the would-be-nice but not must-have list was cruise control. This truck doesn't have it, which wasn't a deal breaker because the truck was way inside my budget.
So anyways, while researching hitches, tonneau covers, steps, etc. I came across this : [URL] ....
Is this all I need to install the speed control? I would assume the dealer would have to get into the logic and enable something, but is this switch really all the hardware I need to buy?

I've looked in the mounds of user manuals as well as searching here but can't find the answer to this question: How do you keep the EV screen showing on the upper dash after turning on radar cruise control? Even if I switch back to any of the EV screens the dang radar ready or the active radar screen takes over no matter how many times I go back to the EV screens. I have already set the option in setup to not automatically return to the previous screen on the 7" HDD screen.

Is there a way to change the default difference on the dynamic radar cruise control from 3 bars to 1 bar?
I think it's annoying to have to change it every time that I start the vehicle and activate cruise control.

The cruise on my 2013 LS460 SWB RWD sucks big time! Both Dynamic and Normal cruise modes are WAY too sloppy in speed regulation. I was out today on a 55mph PSL two-lane with set speed of 59mph. On a long SLIGHT downhill, the indicated speed topped out at 70MPH!!!
BTW, tranny shifting was weird during this episode with a prolonged run at over 3k RPM. At any rate, that's 11mph over the set speed for the arithmetically challenged. So instead of tooling along at a maximum of 5 over the PSL as my 2007 LS would have done (set speed 59 + overspeed 2 = 61 indicated = 60 actual, so 5mph over PSL), I'm flying at 10mph over the PSL ripe for the picking by any county sheriff (and I saw THREE of them on that road, all with their radar on).
I figure my car's speed regulation (in both Dynamic and Normal cruise) is +11mph/-2mph for set speed of 59mph. That is crazy!

I was driving home from school last week and noticed my cruise control would stay set for 5 minutes or so, then slowly (over several minutes) lose speed. I've noticed it happen before, but very infrequently and usually if I stopped to use the restroom, when I started the truck back up it was fine. This time it continued to happen.
As I was getting nearer to home, I noticed that while I had the cruise set, I would hear a high squeaking noise in the dash almost dead center under the radio. Then , when I would tap the brakes, there would be a rattle. This would only happen with the cruise set.
Noise in dash - YouTube
Not sure how well the squeak can be heard, but the rattle is definitely audible. What the cause might be? Electrical, mechanical, are the cruise and the noise even related? Other than that, the truck seems to be running alright.

I just noticed the other day that my cruise control stopped working.
The cruise light will come on, but when I try to set it...nothing. The speed just drops off.

I'm trying to figure out how / if cruise control can be added to a 2005 F150 with the 4.2L V6. I bought an aftermarket kit, popped the hood, and then learned all about electronic throttles . What (aside from adding the cruise control switches) do you have to do?

Truck is an 02 F250 Automatic 4X4, 7.3 PSD.
Cruise control will turn on, will sometimes set speed and sometimes will not. If it does set and work it may kick off at any second or it may run fine. I have noticed it seems to kick off mainly after going over a slight bump in the highway or it may just kick off for the hell of it. Truck has 50,000 miles on it, I bought it new. Also having trouble with the throttle position sensor, it seems to have a "dead spot" at about 58 mph that shows up when I romp down on the pedal to pass on 2 lane roads. Can these two symptoms be related? Both are very aggravating. FWIW it does have the power adjust pedals. Truck is 100% stock, no power chips or other upgrades.

i have a 96 ranger and want to put cruise control in it. is the wiring there and what other parts do i need to get without going aftermarket.

I was driving slowly with cruise control on when the check engine light came on, a few restarts and it still didn't go away. All fluid levels are OK, no other errors show up on start-up or driving and the car drives fine on both ICE and EV modes.
I'm bringing the car in first thing tomorrow. I called my usual Lexus guy and he didn't know what the problem could be either. I'm a bit freaked out, to be honest. Wish I had an OBD dongle to use with Carista.

I have a 2012 Camry SE I4. The problem is my car speed odometer is faster than my radar detector speed. I have 2 detectors and they are both not show the same speed compare to the speed odometer. For example, I am going 70mph, the detector reads like 67-68mph. So the speed odometer is off about 2-3mph. I have OEM size on my car. I know the GPS on my detector is more accurate. So my speed odometer has problem?
