Prius (2004-09) :: Cruise Control Intermittently Flashing On Dash As Malfunction
Sep 2, 2010
I just returned from a 4K trip through 7 states and my cruise control will go batty and make you pull over and re-boot the car. Basically I am cruising down the interstate with cruise control on. When I come into a town I will either pull the cruise lever forward or step on the brakes to disengage it.
The traffic comes to a stop or slows to a crawl for a short period of time. Once the traffic starts to move again and we are back to highway speeds I can no longer use the cruise control because it is intermittently flashing on the dash as a malfunction. The only time it doesn't do this is when I am slowing down if I turn the power off to the cruise control system.
I stopped in the middle of my trip at two different dealers and there were no codes stored. One dealer charged me a diagnostic the second didn't after I showed him my receipt from the day prior from the other dealer but then he wanted to sell me a brand NEW MFD.

My engine and cruise control lights keep flashing....This happens intermittently (been going on like this for several months). I took it to my mechanic and he cleared the computer...was fine for awhile...but happening again. Mechanic said that if it happened again, it might be the catalytic converter. I hope not b/c this is a very expensive part to replace!!! Is my mechanic correct or could it be something else?

About 2 months ago ('06 Prius - 386K) 12v battery was replaced - red triangle disappeared and everything has been fine. ( I have driven the car about 7K since replacement).
Now on my 2800 mile trip, the following is happening. With Cruise Control on and functioning - freeway traffic comes to an almost halt (5-8 mph) after traffic picks up Cruise Control light on dash is flashing and will not function. (Pull over and re-boot the Win95 machine - and everything is back to working until next slow down).
I am now driving on a service road to my hotel at approx. 25mph and as I go over every patch in the asphalt my Traction Control light comes on and then off and it makes the car act like it is on ice ( and yes the Cruise Control light is back to flashing).
On my journey on this 5 miles of access road then my stereo volume starts going up and down all on its own. If I try turning the volume knob nothing happens. I push the knob in and then push on the knob to come back out and then the volume knob works and then the volume control on the steering wheel starts to work as well.

Had an intermittent problem with my Cruise Control engaging. The CC light would come on when the CC on/off button was pressed.
When the CC would engage the "set" light would come on and the speed would hold. On occasion the CC would not engage.
I looked are reread the owners manual.....NOTHING! I was double checking to make sure there was nothing different with the hybrid. (I have owned Toyota for a very long time...since 88').
Since the Hybrid is new to me, "shifting" is a little bit different. There is a "B" on the shifter which is mentioned for "downshifting". There is no mention that once you are done with downshifting that you must shift back to "D" for normal operation. The only mention is not to run in "B" for an extended amount of time.
So, when you are in the "B" position, the CC with disengage.

First it wouldn't turn on, at times now it at times won't work even though the light is on, on the dash. At other times it works as expected. I dun think it's the 12V battery, because when only the center console is on in diagnostics the battery reads 12.2-12.4 and 14.5 + when the engine is on.

My Prius cruise control will intermittently not activate when I try to turn it on. One day it will turn on and work fine. The next day I can not get it to turn on. I took the panel off of the back side of the lever and the contacts look ok for the on/off button.

My mechanic can't find the problem. Engine light comes on. Along with the flashing cruise control. His diagnostic doesn't show him the exact problem as the voltage changes. He has checked everything related, changed out the bank 2 sensor 1 oxygen sensor, but can't find the problem. I don't know the diagnostic code. But he says that it doesn't give him an exact code. Can only the dealer do this? Car runs fine.

engine light and flashing cruise control switch--computer says replace bank one---so I replace with factory catalytic converter----six months later light comes back on with flashing cruise control switch and computer asking me to replace bank one---So I use computer to shut light off----four weeks later light comes back on----called dealer they said "we usually replace both banks"---I found it most painful paying for dealer supplied catalytic converter even when I was under the impression that it would keep light off.---This is my wife's car and she is not really buying the piece of black electrical tape I placed on dash over check engine light.---Am I dealing with a bad oxygen sensor ?

I have a 2006 Prius and was just on vacation for two weeks and my Prius was stored in my garage. My wife just drove the Prius about 6 miles and all the dash lights came on. The car still drives, but the cruise control won't engage. A few months back I replaced the aux 12 V battery as it somehow died, so I don't think that is the problem. When the car is off, the aux battery voltage is 12.5 volts. When it is running the voltage is 13.9 volts.
I disconnected the aux battery and then reconnected it and all the problems went away for a while. Cruise control worked again, too. I just drove it a few more miles and it happened again and just as I got home to go up my steep driveway it would only go about 3 mph. Is that the "limp mode" I have heard about? What this might be? All the dash light are lit - red triangle, check engine, VSC, Brake System, etc. I am a newbie to this site, but I did a search and didn't find much that sounded like this problem. All the lights came on previously when my aux battery died, but the car wouldn't start, so this is somewhat different.

Question regarding a 2002 Dodge Dakota, 2wheel drive ext cab 100,000 miles 6 cylinder engine. Cruise control stopped working, get the indicator light on dash, but no cruise.
Would I start with the Clock Spring? Will Durango parts interchange? ABS Light, was told the problem is the main unit that mounts on the driver side fender. Have tried replacing with other units from the local scrap yard, but still get warning lights/sounds.

I'm at my wit's end trying to install cruise control in my 2009 Corolla. I thought it was a relatively easy install, but then after putting the airbag in place, I find that the horn no longer works. I test out the cruise control, and the green "Cruise" lights up on the dashboard..but it doesn't actually work.

Cruise control on, set at, say 65mph. I want to lower the speed to 60mph. Tap down... click-click-click-click-click and watch the set speed number drop to 60.... then pop right back up to 65 and the car accelerates back to faster set speed. This has happened more than once now.

I have a 2011 GTI, has about 4000 miles on it. Sunday went for a quick ride down some FM's and on the hi-way. Got up to about 85mpg for about 10 miles, hit the exit back to the house which is only about a mile away. On that mile ride home I took it real easy maybe 35-45 mph decided to have a little AC also (outside temp 90F degrees).
I pulled into the garage sat and idled for about 30 seconds, on the MF display up pops the Cruise Control Malfunction icon ( amber on the MFI,But the owners manual says it's RED. it's a cruise symbol with a giant exclamation ) then it goes away. I looked at my cruise stalk, cruise was Off. I turned it on and up Pops the Malfunction Icon again then goes Off. Took the GTI back out and No Cruise malfunctions. Also, when I did finally park the Car both cooling fans were on for at least 4-5 mins after I had shut everything down.
Did I run my little GTI too hard? Is the Cruise control Malfunction icon like a nuisance message that doesn't really mean anything or, is it a sign CC it's already toast, or getting ready to go.

I have a 2005 Subaru Outback with 179,000 miles on it. My engine and cruise control lights flash on and off....have been doing this for 6 months now....intermittently. My mechanic said the he cleared the computer and to wait and see if it happens again. He said that it might be the catalytic converter. The car runs fine whether or not the lights are flashing.

Mine just quit on me. Nearly 180K. 2008 Gen 2. I watched that youtube video, they were working on a Corolla. Seems easy enough, it's a pricey part though. It's called an airbag clock spring. I don't think it's the stalk. The button feels the same as it ever did.

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.

My Prius is a 2009 with 30,000 miles.
Have just begun to have an intermittent problem with the cruise control (has happened twice in past month -- never happened before).
Turn cruise control on, but it will not set. Turning off cruise control and turning it back on didn't solve the problem. However, stopping and turning the vehicle completely off and turning it back on did solve the problem. The second time this occurred (this morning), the engine sounded like it was revving and seemed somewhat sluggish (not what you'd expect if the engine was revving). Not revving real fast, but noticeable.

I feel like I am going crazy but it feels like when driving up long steep 6-7% grades if I set the cruise control for 65 I can go 65 the whole way. If however I just use the gas peddle the car bogs and slows enough to get passed by semis (maybe not that bad but it feels like it). Is there a rational explanation for this behavior?

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.

I have a 99 Passat 4 cyl turbo and the cruise control seldom works. Sometimes it works, sometimes not, and sometimes it shuts itself off. What could be the problem?

I had had intermittent issues with the cruise control not working in my excursion. most of the time it was fine though. after a recent 150 mile trip it stopped working half way through. i didnt worry about it too much..got back into town and checked under the hood. i found brake fluid running down the inner fender well! all over everything under the master cylinder. finally tracked it down to the cruise control switch on the master cylinder leaking. I pulled the plug apart and it was full of brake fluid.
Meanwhile the master cylinder was about half full, so i replaced it with the same switch out of a '96 parts explorer which is the same part luckily. also yes i have had the cruise control recall done. So if you have lost CC and you have a leak replace the switch! seems it can leak..and at a pretty good rate..alittle scary! glad i figured it out before my 800+ mile trip later this week/weekend.
