Prius (2004-09) :: CEL Came On In Cruise Control Mode
Very very odd thing happened. Driving up from Houston to Colorado yesterday. Snow tires mounted in preparation for the snow in NM and CO. Around 300 mi into the trip, the CEL (check engine light) came on. I was on cruise control, I did not notice the lack of power. Checking the battery, it was in the purple. I first opened the gas cap and screwed it back in. I figured the change in elevation or temperature may have had something to do with the CEL. Nothing. Gas tank was a quarter full.
At Lubbock, I pulled over and filled up. I played with the rubber gasket on the gas cap but decided it was going to be more trouble than I was prepared to deal with, without any tools. CEL stayed on for another 30minutes or so while I navigated through the city, covering another 20 miles or so. After a pitstop to pick up OJ, I started the car and the CEL was off.
Here are the variables:
Elevation delta - +3000 ft
Temp delta - -10F
The only thing I can think of is that the hybrid battery is getting long in the tooth (2008 MY, 103k mi), the wind in the high plains chewed through the battery power, and the long length of being in low charge got the ECU to confuse itself into thinking that the hybrid battery has bad cells, which it probably has a few weak cells.
Camry 2012+ :: RPM Tends To Decrease In Cruise Control Mode
So the problem occurs while I am driving with cruise control on . Suppose I am driving at the speed of 80mph with 1300rpm, few seconds after I come downhill the rpm shifts to 2000 and comes back to 1300. Now I understand that the rpm will increase as I go up in order to maintain the speed but this problem occurs once I come downhill
And today also while driving without cruise control on I experienced the similar problem. I got a SE V6.
Prius (2010-12) :: Cruise Control Is Disabled If In B Mode?
About 2 months ago, I was driving and my cruise control wouldn't engage on the highway ... I happened to be right near the dealership so I immediately returned there .... didn't turn off the car, but the tech put it in P while I was waiting. I was so ticked off because I thought that may have 'reset' things, and of course when the tech took the car for a drive (in D) the cruise worked fine. We of course never confirmed that the cruise control didn't work.
Today, the same thing happened at the same place, so I returned to the dealership, calling them on the phone, and informing them that I would not turn the car off, or allow the car to be put in park. The service manager met me out front and we went for a quick ride so I could 'prove' that the cruise was inoperative. He confirmed that it was not working, and why. For some reason, I glanced at the dashboard and noticed that the car was in 'B' mode. I mentioned that to the manager and he noted it as well. I must have bumped it somehow while driving as I NEVER use B mode for anything ... ever. I said I wondered if that was the reason, and put it in D, and lo and behold, the cruise worked again.
I haven't checked the manual yet to see if this is stated there, but the cruise control is inoperative if the car is in B mode. Or at least it seems that that is the case. Other than the car being in B mode, it acted just like it always does, and since I was on the highway, I never noticed the braking effect that B mode gives you.
Ford :: 2013 - EV Mode Won't Work In Cruise Control?
I own a 2013 C-Max hybrid and I notice that during long drives if i engage the cruise control, I don't get as many EV miles as I do when I have my foot on the gas pedal and take it off when i have reached my desired speed. Does EV mode not work in cruise control? My feet start to ache a bit with constantly having to press and release the gas pedal just so that I can generate some EV miles.

Phaeton :: 2004 - Adaptive Cruise Control Causes Limp Home Mode
I am one of the few that has ADC on my 2004 V10.
Occasionally, 3 times now. I press the ON button and the cruise control does not initialize properly. After a while it will say "Temporarily unavailable" . The problem is that then there is no power any more.
I stop on the hard shoulder of the motorway, engine off, engine on and all is reset, ADC works ok and full power is restored.
Touareg :: EPC Light Comes On If Car Goes Into Limp Mode And / Or Cruise Stops Working
Just to save you all some time.... If your car goes into limp mode, and/or cruise stops working, and the EPC light comes on..... We had over a week of downtime and hundreds of $ out to find out that the literally brake light switch broke - its apparently flimsy and triggers all kinds of electrical faults..
View 1 RepliesPrius (2010-12) :: Battery Charging While Going On Downhill Especially With Braking Mode / Cruise Control On?
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?
Elantra MD (2010-15) :: Cruise Control Will Not Set The Speed
So my cruise is giving me issues, won't set the speed. Turns on and off no problem but set and resume do not work. However, turn off the car and then re-start it and the cruise works again. I know the radio is only up to 60k.
View 19 RepliesTouareg :: Cruise Control Won't Stay On
I didn't feel like putting my foot on the throttle. turned on and set the cruise control at 60mph. and 5 mins later, the car slows down. i look down at the speedo and my speed is dropping.... THE CRUISE CONTROL LIGHT WENT OFF!
so I turned it back on again... set my speed. this time it stayed on for 30 seconds. turned it back on. And it shuts right off. Then I had to exit the highway. flicked the right signal... (i was expecting 3 blinks) blink pause pause pause pause half-blink.
I hit it again. this time I turned ON the right blinker. blink pause blink pause blink. I know it's late and all... I'm pretty tired myself. but the Touareg can't be tired and lazy like me! what's going on?
on top of that, earlier tonight, I hit a pothole and my left xenon went out. i thought the housing popped out, I stopped at a gas station popped the headlight back in. xenon still dead (every other bulb is still on) i thought to myself: "great. the bulb died. now I have to go home and get my old xenon bulbs" went home. swapped the xenon bulb to my old one. popped the headlight housing back in. STILL DEAD. WHAT'S GOING ON? I'm approaching 10k and my car is dying on me.
Touareg :: Cruise Control Won't Stay On?
no i am not hitting the brake.
it works intermittently.
i would turn it on, set my speed and the cruise control light would go off.
sometimes cruise will be on for 5 mins... sometimes only a few seconds.
Touareg :: Speed Won't Display With Cruise?
My owners manual says that when cruise is turned on there is a "cruise" symbol in the color MFI - that works as advertised. It also states that after pressing "set" at speed the set speed should also be displayed.
Do a 'set' speed display with cruise and if so do you have NAV or not. Do you have Color or Red MFI ?
What VIN series - I am 37XXX

View 6 RepliesTouareg :: 2010 - Cruise Control Would Not Engage
I searched here, but could not find anything. My cruise control would not engage this morning. Worked fine yesterday on the way home. Of course the car just passed 30K Miles (now at 30,800) and will be out of warranty. I looked in the owners manual and could not find the number for the fuse and if it is in the right or left panel on the dash.
I will also check tonight when driving home if I can shift into gear w/o pushing the brake and if the green "push break pedal" indicator comes on or not when I try to shift into gear w/o pushing the break pedal. I read on this forum that this could indicate a fault in one of the switches at the brake pedal.
BTW, it's a 2010 Touareg with the 3.6L V6 and 30,800 Miles on it. So, what fuse to check??
Lexus LS 2007+ :: Cruise Out Of Control - Sloppy In Speed Regulation
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!
Passat (B6) :: 2006 VW - Cruise Control Current Speed Display
When I first got this car about 2 months ago, my current speed would be displayed in the MFD when the cruise control was set to on (not activated and in use). For some reason now that no longer happens and it just shows dashes. The only time the speed is displayed now is when I am actually using the cruise control. Is there a way to get that thing back to showing my present speed like it did before?

I have a 2006 santa fe with th 2.7. The tail lights light up both films on both sides when you turn the lights on. Now the cruise control will turn on but it won't set the speed. I changed the brake switch and i tried to put it in the same exact spot. The old one was not sticking or anything. Now I was told the switch might need reset or something. I looked everywhere for shorts and sealed them up. Checked all the fuses which all are good. So im not sure whats going on. Now when you press the brake the small fuse will burn out.
