Lexus LS 2007+ :: Dynamic Radar Cruise Control
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.
Lexus LS 2007+ :: LS460 Cruise Control Does Not Perform Automatic Downshifting
I have a 2007 LS460 and one issue I have, which could be costly unless I'm paying attention, is the cruise control does not perform automatic downshifting like my Honda does. In fact, my speed can increase by about 10-15mph going downhill, which a couple of times I've been lucky to realize my speed is increasing and downshifted manually and sure enough there was a speed trap. I really don't like driving by luck, if you know what I mean.
Is there something that is causing this? I do not recall that it has ever worked correctly...
Lexus ES 2013+ :: 2016 - Adding All Speed Dynamic Radar Cruise Control
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.
Lexus GS 2013+ :: Dynamic Radar Cruise Control Fails To Slow Down The Vehicle
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)
Prius (2010-12) :: Speed Range Of Dynamic Radar Cruise Control?
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?)
View 18 RepliesAvalon 2005-12 :: Dynamic Cruise Control Acts Erratic And PCS Warning Goes Off Periodically
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).

Dealer told me needed new control arms as the bearings are wearing out. Was quoted a little over $3k. Doesn't really bother me bc it only makes a clicking noise when I apply brakes hard but concerned about safety issue. Surprised a car like this would need new control arms with only 70k miles on it.
View 14 RepliesLexus LS 2007+ :: Cruise Control Module - Deactivates At Around 25 Mph
Do our cars have a separate cruise control Module? I drove a new 600 the other day and found that the radar (adaptive) cruise will bring the car to a full stop. My 2009 will not. It deactivates at around 25mph. I emailed another 2009 600 owner who is overseas. He said his also comes to a full stop. So I'm wondering if I can put in a new module, or an overseas module, and get the results.

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!
Lexus GS 2006-11 :: 2007 GS350 Speed Just Drops Off / Cruise Control Not Working
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.
Lexus GX 2004-09 :: AC Diagnosis Shown On Nav Screen - No Option To Change Climate Control
Yesterday all of a sudden the lights on the instrument panel started flashing and the RPM indicator started fluctuating . The RPM indicator would rev and bounce all over the place while the engine was. At a constant speed. Same thin happened before when the alternator went. Next the A/C sort of went and the NAV screen showed Air Condition Diagnosis with no options to change the climate control on the screen. When I got to the car I noticed the 110v ac button was on, not sure how long she had it engaged. I turned if the 110v button and unplugged the battery to reset the computer. All seems fine driving it for 20 miles now.

View 7 RepliesLexus ES 2007-12 :: ES350 OR LS460 Which One Is Best
I have tested 07 UL package a while ago, really liked the car, how it drives, really quiet, very smooth, good acceleration, very comfy etc. the only concern for me is it spacious enough ? I'm driving around 90% in town, how is it on a long trips with 2 - 4 people.... ?
Immediately after I parked ES 350, I have tried LS460 07 AWD, somehow it felt under power for me, maybe cuz it's a awd.. ES was faster in my opinion. It had it 100k miles on it, the car felt really solid like a rock, safer, but slower. Maybe a RWD would feel differently.
My plan is keep the car for 5 years or so, I'm also concern about maintenance costs too. As today I'm pretty much can get a LS 460 07 or ES 350 UL 10-12' for the same price.
Lexus LS 2007+ :: LS460 - Vibration At 65 - 75 Mph
I took it in to Charles barker Lexus (our dealer here) and they said the water pump was leaking, the front struts were totally blown out, and the 2 belt tensioners had some free play.
Got the dealership I purchased from to pay for the water pump but they would not cover the struts because they said the car pass inspection so they don't believe they are damaged.
Got and independent shop to replace the front struts with kyb 551122 for $400 parts and labor. While they were under the car they said the upper and lower control arms looked newer as if they were replaced recently
Got all wheels balanced at a little small used tire shop small change. The vibration that started at 60mph now starts at 65. Question is are all tire balancers created equally?
Lexus LS 2007+ :: LS460 Transmission Slips Between 2 And 3
I purchased my first Lexus in October, a very clean 2009 ls460. In colder weather (for Tucson AZ) in the 30's to 40's I notice that the transmission slips while the car is accelerating between 2nd and third gear.
By slipping, I mean as the car shifts between 2nd and 3rd it feels like it goes into neutral for a half second, so rpms spike 500 rpm, the car stops accellerating, and then catches as the next gear is finally engaged.
It does this pretty much every day when the car has been sitting overnight on the first steady acceleration after backing out of the garage. It only does it once, subsequent shifts a re pretty much normal.
Every once in a while coming out of a parking lot after say grocery shopping, it will do it again, just once.
I dropped it at the dealer and they of course could not replicate it.
I made a youtube video which shows it sort of. besides the rise in engine rpm, you feel a lurch in the acceleration as it drops down into gear.
Service records showed the trans was serviced just before I bought it.

Lexus LS 2007+ :: LS460 Trunk Won't Close
My wife has a 2007 LS460. Some dummy at a big box store tied down the trunk to get a chair home by threading rope through the latch mechanism. Needless to say, the trunk will not close. Not with the button or manually. I tried the disconnect battery thing. Nothing. The lid goes all the way down.
View 14 RepliesLexus LS 2007+ :: General Vibration From 75 - 85 Mph On LS460
Our 2007 LS 460 (98k miles) drives like a dream except from about 75-85 mph we have a general vibration. Its most evident in the steering wheel but everything in the car has a general vibration. It may have been there for a few months now, but I felt it when I drove it yesterday. There is absolutely no vibration below 75 and none above 85 (I was cruising at 90 mph and the car was solid). I tried to do some investigating:
Tires: Appear to be fine in regards to wear and the tire pressure is about the same in all of them in the mid 30 s. Alignment is fine and the car does not pull to any side.
Brakes: New brake pads about 10k miles ago at dealership and work absolutely fine.
Transmission / engine (I hope not): The car is 7th gear at that speed but it usually is anytime above 50 mph so its quite odd. We don't lose power and no lights are set off.
Body work / damage: doesn't appear to be anything on the front or sides of the car that cause this.
Lexus LS 2007+ :: GS450H Or LS460 Sport?
I've been waiting for to trade in my 04 Acura TL and move up drastically to either a 2010 GS450H or 2010 LS460 Sport. Both are driving me crazy because I absolutely love the look of both cars and the more I keep looking at the wheel photos makes it even harder.
I have 3 kids but 2 of which are older so size doesn't matter. I do prefer the GS due to the super sleek looking and 20" are a win BUT the LS on 22" with the air ride and data controller is a super win!!! not to mention the 19 speakers are better then the 14.
I know that I have to drive each car and I have not yet. Also pricing is pretty close for each car and it looks like the gas mileage is also pretty darn close so I don't believe that is an issue either way unless I'm wrong??
Lexus LS 2007+ :: LS460 - Electronic Power Steering Is Out
Got in my 2007 LS460 and it wouldn't start. No power, no clicking, nothing. I checked the battery terminals and noticed they has some corrosion so I cleaned them and reattached. Nothing. I found that if I jiggled the positive cable the power would light up my dashboard with every light / radio, but it still wouldn't start....and I had to disconnect the cable in order to turn the power off. I had the car towed to a trusted Toyota/Lexus repair shop I've used for 15 years. They connected the cables to the battery and it started right up....but the power steering is out. They tried multiple things to get it working with no success. The only option now is to replace the electronic power steering unit.
