You were driving on freeway so following probably doesn't apply. But just a clue, if below 20 mph and there is no car in front, ACC will not engage, and the message is "not available".

I have 10K miles on mine, always most recent updates. PA not turning on could have been the lines on the road were crap, too much snow, too much sunlight, you speed was too low, etc. I can literally replicate every condition, because I use PA for most of my 1 hour each way drive to work. This is not Tesla, PA is not auto pilot, Volvo has a lot of lawyers and they know customers sue.

 

Op was concerned about ACC, not to mention PA.

This is good interstate highway (I-95 from Baltimore to Washington), and I was trying to engage it at 65-75 mph. Moderate traffic, in the middle of a partly cloudy day. I was trying this over 15-20 miles before I gave up. I'll try it again today and see what happens. Stay tuned.

 

Adaptive Cruise control "Unavailable"



Have you checked your settings on the left functions page on Sensus to verify that ACC is the default and not CC?

Drove the same highway today. Conditions were worse. Rainy. And the ACC worked fine.

I think it was just a software glitch. If I were on a long road trip and this happened, I'd exit the highway and turn off/restart the engine. But I hope it doesn't happen again.

 

Doesn't ACC require that there is a vehicle in front of you to activate?

 

Where are the darn CTL-ALT-DEL keys????

 

Adaptive Cruise control "Unavailable"

Not with ACC or PA2. I will try to locate some info as my MY16 with PA2 Upgrade does not require a lead vehicle - only highway markings and decent weather. That has been the case for 1.5-2 years now. I will try to distinguish between ACC alone and ACC with PA active once I find some useful info.

ACC vs. ACC with PA. Now that's something I've never been able to figure out. I'd be glad to hear what you find.

 

That is how it started with my 2015 V60R.
Sporadically it would say "Adaptive Cruise Control Unavailable" until it stopped working all together and it's telling me to take it in for service.

Has anyone else experienced this?

I have the same problem on my 2014 V60 Plug-In Hybrid. The ACC works for about 5 kilometers and after that it turns off and the "Adaptive Cruise Control Unavailable" message is displayed. Went to the dealer and they said it's caused by communication problems between the TFT instrument cluster and the ACC. They are asking more than $1100 for new cluster, but this seems strange to me. I would totally search for another opinion on this, because the cluster seems fine and the ACC works for the first few kilometers on every new trip.

 

Next time you stop switch the power shutoff/ battery disconnect off for 20 seconds that should reset it. From what I was told the error is connected to the front sensor being dirty. While that off and should be good.

 

Just FYI for anyone scouring Google for answers on this like I did before - a power disconnect/reboot wasn't going to work for me, as I have a T8. Turned out my issue was the parking brake wiring was damaged. Repairing the wires resolved the issue. Cruise, adaptive cruise, and the parking brake were all not functioning.

Dealer stated often times when one sensor/system malfunctions it disables other systems that may use it as a precaution.

 

Was it permanently unavailable before repair or transiently?
