Prius (Gen 4) :: Loud Beep And Cruise Control Is Unavailable Message When Driving On Freeway

Yesterday while traveling on the freeway and using cruise control my 2016 Prius beeped loudly, displayed the message "Cruise Control is Unavailable" and dropped me out of cruise. I turned cruise off and back on, and got the same message. There's also an orange indicator light blinking that looks like a car hitting another car, and the "Cruise Control is Unavailable" message now displays on the info panel every ten seconds*. Collision prevention is also unavailable.

Was this something I did wrong? Is there a way to get cruise control and collision prevention back?

Hyundai - Elantra :: 2006 - Cruise Control Cuts Out After Driving For 25 Minutes

The cruise control cuts out after driving for 25+ minutes. The rpm's rev up to 4000 and the speedometer goes wild just before cutting off. It can be reset but does not hold for long. Short trips and a cooling-off period for the engine seem to work. The dealer could not replicate the condition.

Sonata I45 (YF - 2011+) :: Cruise Control Will Completely Stop Working While Driving

So I've had my 2011 Hyundai Sonata since May of 2013 and I've had few problems with it until now. For some reason, at seemingly completely random intervals, my cruise control will completely stop working while I'm driving. What exactly I mean by this is that I'll be driving with cruise control set and suddenly it kicks off and I have to continue by manually controlling the gas pedal. I am also completely unable to turn Cruise back on until I have shut off the car and turned it back on. There are also times where I'll have Cruise control "On" but not using it and suddenly the Cruise indicator light on the dash will disappear, I'll try to turn on Cruise at that point and it will not work. Again this is the case until I turn the car off and then back on again.

I have followed a couple guides on adjusting the wiring harness in the steering wheel, behind the air bag, to make sure it is not a loose connector issue, but this has not seemed to work. Another reason why I think this may be something more than just that is that I'm also having transmission issues that seem to correlate with the times that my car loses the ability to use Cruise Control. Everything is completely fine with the car, including the transmission, until the above mentioned issue occurs, at which point if I happen to be driving below about 50mph, or reach a point where I have to slow down below 50mph, my transmission begins to intermittently disengage and reengage fairly erratically. It has happened a couple times while cruising at around 65-70mph, but has acted the worst bellow 50mph.

To make things even MORE confusing, the transmission issues seem to correct themselves with a simple shut down and restart of the car, just like with the Cruise Control problem. I'm at a complete loss now. I don't want to deal with a dealership unless I absolutely have to.

Isuzu - Rodeo :: 2000 - Lost Speedometer / Odometer / Cruise Control While Driving

As stated in the title, I have a 2000 Isuzu rodeo s fwd v6 SUV. While driving on the road recently I lost my speedometer, odometer, and cruise control. The odometer is digital and I can still read the display when the car is on, however the number never changes. There is a little over 185 K on the odometer. I did some research on my own and figured the problem was my vehicle speed sensor (VSS). I thus bought one, changed it without problems, yet my problem persists.

Now when I drive for a bit, and come to a stop my vehicle sometimes stalls. Not all the time though. I figure even though the VSS is good (I changed the second one I put in again for a factory VSS and still I get no change) maybe the signal isn't getting to the ECM. What are my other options for the issue? Could it be the cluster behind the console? Is there a speedometer cable in this vehicle that could be causing this problem? Is there some little selenoid somewhere that is bad and is causing these problems?

Ford 7.3L Power Stroke (1999-2003) :: Cruise Control Cuts Off While Driving

This has happened 3 or 4 times now while driving down the road. Just cruising down the road the CC will just cut out. I'll hit the "set accel" button on the wheel and all is good again until it randomly decides to do it again.

The only thing I've changed recently is the rear end speed sensor to cure the ABS light. I wouldn't/didn't think this would have any effect on the cruise control, but IDK, maybe I'll put the original one back in and test it.

Lexus ES 2013+ :: ES300h Check Engine Light On When Driving Slowly With Cruise Control

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.

Prius (Gen 2) :: Cruise Control Not Engaging

My cruise control doesn't work anymore. There is no blinking/cruise icon on the dash--period. Is this the result of the button being worn out or a relay/fuse? My little tank has 231k, so it has been used. BTW, I can't seem to find a write up for replacing the switch. Is there one?

Prius (Gen 3) :: Stalled Out On Highway From Cruise Control At 65 Mph

My Prius just stalled out on highway from cruise control @ 65 mph, so I coasted luckily off an exit, and before coming to complete stop the whole dash went black with exception of power steering failure warning light. I had it towed, at my cost of $95, to dealer for troubleshooting. They found that the fuel sensing system/indicator had worn, and cost for repair is $422+, as not under any warranty or recall. Fuel sense indicator worn out @ 105,145 miles...

Prius V :: Cruise Control On Steep Hills

In ordinary cars, the cruise control (CC) only has control of the throttle. That is to say, when the car encounters a hill, the CC system increases the throttle. Coming down a hill, the CC unit will reduce throttle. If the speed increases too much, the CC unit can not reduce the speed of the car. On especially steep hills, the speed may well become too high.

In contrast in my Prius v, I find that the CC holds the speed study even on steep downgrades. This is possible due to the hybrid system which regenerates power. Even on steep grades, the CC system holds the speed rock steady at the set point.

Prius (Gen 3) :: Cruise Control Engaging Intermittently

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.

Prius (Gen 2) :: Cruise Control Only Works Intermittently

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.

Prius (2004-09) :: Cruise Control Just Quit

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.

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.

Prius (2010-12) Fuel :: Using Cruise Control For Better Mpg?

If i am driving say for 15 mins on the highway at 65-75 mpg with a few brakes and accelerations in between due to other cars around, is it better to use the cruise control (i have adaptive cruise control on my prius v) and let the car figure out the throttle and braking or is it better to just drive by myself without using cruise control? i read about the different pulse-glide driving methods.

Prius (2004-09) :: Cruise Control Will Not Set When Turned On

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.

Prius (2004-09) :: Using Cruise Control In The Mountains

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?

Prius (Gen 2) :: Cruise Control Won't Engage - All Dash Lights Came On

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.

Prius (Gen 3) :: Cruise Control Lost While Taking A Turn

I have only a week ago returned from a 4300 mile odyssey with no problems, but yesterday while taking a turn in the country, my cruise control vanished! This is a Gen III, model IV, STANDARD cruise, and out of warranty, 43K. Stopped briefly to go into a shop and when I came out and started the car again......no cruise! No it wasn't in "B", all of us have had that happen to us at some point if we use B at all. It continues to be "non-functioning", and w/o any green pilot light on the dash display, or despite that no engagement,....I tried.

I figured it must have blown a fuse. The owners manual is quite good regards both the under hood and the under dash fuse boxes, telling you what each one is for, etc., but I can find none of these fuses with a code that I am even remotely confident is for the CC. Where is the fuse for the cruise control? Is it in another remote area? What is the "code" for it? Or if it is in one of these fuse panels, what # is it?
