Avalon 2005-12 :: Dynamic Cruise Control Acts Erratic And PCS Warning Goes Off Periodically
Apr 4, 2015
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).

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.

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 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)

We just got the car and I know for fact the CC worked before. Now I don't even get a light when pushing the on/off button on the end of that incredibly weak column arm.
Is there a fuse, or relay? I checked under the hood in the fuse/relay box everything there seems fine, although I don't know if 1 of those relays controls the CC?

The cruise control on my '05 Avalon Limited was working intermittently for a while. I'd hit the button to turn it on and nothing. Then a few miles down the road, I'd hit it again and it would work just fine. Today I tried to turn it on and nothing. Three different trips today and no luck.

The green light comes on but the cruise control does not engage. It did work one time the other day but usually doesn't. What should I check?

I have an '05 I bought 3 years ago and any time it sits outside and gets rained on, the VSC/check engine light comes on when I start it and it doesn't go away for 2-3 days at a time. The frustrating part is that any time this happens, I get the E3 error with the cruise control even though there's not a drop of water to be found anywhere.

My 2005 Mercury Montego has a weird issue with the cruise control. I have already taken it to a Ford dealer once. They claimed the switch on the brake pedal was the issue. It isn't.
At 70 mph, with cruise control OFF, take foot off accelerator and push on brake pedal. Works great.
At 70 mph, with cruise control On and engaged, the brake acts like the engine is off. It is very hard to push. It is like the engine is OFF and the vacuum assist is gone. Press really hard, and the car will slow down. Jab the brake once first (hard), then apply brakes, and it is fine. Push the cancel button on the steering wheel, and all is well. The few times I have looked, the tachometer has not moved. Car has CVT.
I bought this car new, and know it didn't always do this. And certainly shouldn't. A panic stop is scarier than it already would have been. Car has around 62000 miles on it.
Mechanic wrote that he observed the issue in a test dive and tested it following repair and it now works. I don't get this at all.

My 2010 Subaru Outback recently surprised the hell out of me by simultaneously turning on the brake warning light, the traction control light, the check engine light and (just for a bonus!) disabled my cruise control while flashing the cruise control light. I pulled over, quickly surmising that all of those systems could not have failed at 70 MPH without instantaneous death to either me or the vehicle. Both apparently still being alive, I tried turning the car on an off to reset the lights. No go. Subaru was not going to miss this chance to get me to the dealership! (who I had avoided to this point!) As I was far away from home and the car being very healthy, it seemed, I decided to drive on. I proceeded to put a couple of hundred more miles on the car before I got back to town.
My car had 39,000 miles on it, 3,000 miles beyond the warranty end. I learned that I have an error code of P0171, "Fuel Trim Malfunction (Air/Fuel too lean)". So I guess I'm wondering about a few things...why would this sensor set off every light on my dashboard and disable my cruise control? Seems a bit overblown for running a bit lean. My gut tells me Subaru has a sensor/software problem they are not owning up to. I'm a big fan of conspiracy theories and this really smells like one...
Second, jeez, I'm only 3K miles over warranty, don't you think they'd cut me some slack. I mean I love my Subaru, or did anyway, until this happened. Now it's just another POS car that breaks for no apparent reason...

While driving to Calif. from Ariz., on I 10, dropping down into Indio on a mild grade, at 75mph, when I came to the steepest section the transmission down shifted, rpm's rose and it felt like the engine was keeping the mph at the set speed, by providing more drag which it did. I have had many auto with transmissions and cruise control, been descending steeper grades, and never have had this happen. The vehicle is a 2014 Avalon. It would be a nice feature if it had been designed to do this auto braking, but I don't think that it ia supposed to do this?

I try to do my own maintenance. I have a 2006 Avalon Limited. This has happened twice recently, using cruise it has kicked off and gives me the VSC light and the check engine light and cruise error, when running codes I get the following P0138 & P2195 both have to do with the O2 sensor on bank 1, and P1578 & P1201 which are brake malfunction. I have been searching the Internet for any information on what could be causing my issue with no luck. I have a 3000 mile trip and need to figure this out soon.

OK - so is my engine computer toast? The other day on the highway on the way home from work, my check engine light started to flash, and the car on cruise decelerated from 80MPH (ok I was speeding) to 70, and flooring it didn't make is speed up, and that's when i noticed it was shaking a little, so i pull off the highway and it's as if a spark plug was pulled.
So I made it to a parts store to have the code read, then started it back up, all was well. As if nothing ever happened. So I dismissed it as a pocket of water in the fuel or some other oddity.
2 days ago it happened again on the highway. So I pulled into the shoulder, shut off the car, and started it again. Runs fine. Engine computer?

I have been using ACC a lot during my daily commute, it's really an effortless way to drive the car on a daily basis.
One of the issues I have been running into with it is that sometimes when the car in front (recognized by radar) accelerates and immediately decelerates to a quick stop my Sonata's ACC does not react and apply the brakes fast enough. The car will basically apply some braking power (~50%) while very quickly approaching the car in front, all the while triggering the rapid beeping of the Collision Detection system. Everytime this happens I have always had to manually intervene and apply the necessary braking power to stop short of hitting the car in front. This is pretty ridiculous to me since if the car KNOWS that it will crash without additional braking, and has the ability to apply the brakes, why doesn't it do so properly?

I have a 2011 Avalon Limited, and recently the VSC warning light came on (and is still on). Following some of the advice on accessing codes (like jumping ports on the OBD2 plug) I ended up getting codes that said my #7 cylinder had intake issues. Funny...I don't recall seeing a V8 under my hood.
I am hesitant to take the car to the local Toyota mega-dealership because of the excessive amount wanted to simply read the codes. How I might either access codes for the 2011 or even how to clear the light in order to see if it returns or not.

I took my Avalon to get Dyno'd to see if module I foolishly bought actually provided any horsepower gains. Much to my dismay, I could not Dyno the car without the module because the traction control wouldn't allow, seeing as the rear wheels were not moving. Apparently, there is no switch for the traction control, but is there another way to disengage it...?

My 2009 Prius was parked for two weeks. When I started yesterday the red triangular warning light, circular yellow light with exclamation symbol in center, and vsc warning lights did not go off. No previous problem with these. Top half of display screen blank. Vehicle started/ran normally. No change in handling or braking. On highway, cruise control would not activate.

I recently purchased a 2014 xle plus. The passenger seat is VERY low and there is no vertical adjustment control. Is there any way the seat can be raised. My wife is 5' 1" and cannot see over the dashboard.
