BSD Cancelled

My first potential issue.

(Blind Spot Detection) BSD Cancelled just showed up on my car today when driving into work this morning. It was raining so maybe it tripped up the sensor. About 30 minutes later it fixed itself.

I went through the entire winter without issue, so I have my doubts that rain will cause the issue.

So now that it's working again, is it worth bringing in to get it looked at or does the rain actually affect this sensor?

I had the same thing happen while driving down the highway once this winter. I couldn't cancel the error so I stopped at the side of the road and shut it off. When I restarted the car the error was gone. I am going to mention this to the dealer to make sure it is documented in case it happens again.

Happens in Warm and Dry Weather

Just happened to me yesterday driving in Death Valley, outside temp about 78 F, dry, so cold temp or wet is not the cause. The error message dominates the screen as you can make it go away by using the thumb wheel, but after a few seconds the message comes back with a warning chime. The BSD was back to normal after stopping at a Ranger Station and restarting. The Sorento has about 11,000 miles now, first problem or malfunction of any kind.

Ya, mine hasn't come back yet either.

It is concerning that this will happen again; but at least it doesn't impact the running of the vehicle.

I didn't inform the dealer of the issue, but hopefully someone will post when there is a solution out there.

It's odd that it is saying cancelled. Were any of you towing at the time? I know on my previous car, a CX5, the blind spot would not shut off even if it was activated all the time, which would happen every time I towed the Utility trailer. I'm wondering if the software in the Sorento is shutting off the BSD if it gets a continuous signal.

Mine happened while I was driving on my regular 1.5 hour commute and then turned off just before I arrived. So ya, I drive this route a lot and no I wasn't towing anything or doing anything unusual.

I think it was on for about half and hour.

I have had this problem a few times in my 2016 Sorento already. I find that it happens when I am on single lane highway and there is no "activity" for the the BSD to detect, as in, I have not passed/been passed by anyone for a while. It drives fine for about 40 mins to an hour, and then the "BSD Cancelled" message appears (and cannot be cleared). Pulling over and restarting the vehicle clears the message for another 40 minutes or so, or giving the sensor something to detect will also make it go away. I'm taking the vehicle in soon for service, so I'll report back here with Kia's response.

good idea, let them THOROUGHLY check that out. Don't let them pass it off to some sort of weather related issue. Just simply say it's a major issue and needs to be fixed. That's what warranties are for, and to be quite frank, it's more of an inconvenience to US to have to bring it in to the dealership, try to explain what's going on and to possibly have to leave it with them and arrange transportation and move things out of the car that you need for everyday life, etc. Have them fix it the first time you take it and you'll be thanking yourself that you approached it firmly with them. Just look how many people on this forum have chimed in with the same issues. In other words, don't give them an out.

I had the BSDS fault (Check BSDS) after a rear bumper repair. I took it to a local garage that has state of the art diagnostic equipment. I was told that the BSDS system has to be reset each time the backup cameras are disconnected. The backup cameras were disconnected when the rear bumper was repaired. The fault was corrected and I went on may way.
The fault re-appeared after one week went by.
I spoke with my local Kia dealer and was told that the BSDS sensor must be calibrated when the backup cameras are disconnected. I dropped off my 2016 Sorrento at the dealership. They removed the bumper and recalibrated the BSDS sensor at a cost of $350.00.
A week went by and you guessed it. The BSDS fault appeared and went in and out several times. I once again dropped off the car at the dealership and lost a second day of work.
Another week went by and guess what? The BSDS fault once again reared it's ugly head. It's been in fault for the past three days. I am hesitant to drop it off again without assurances that they had a permanent fix.
I was told by the dealership that the sensor was not damaged.
Has anyone else experienced this problem? If so, was it fixed? If so, how?

I've had this happen twice a 19EX, both times about half way into a 10 hr. drive on a major wide open highway. Once in rainy weather, once in clear and both times it re-set its self after a restart.

The BCW (Blind-Spot Collision Warning, Kia's terminology for BSD, not mine) function is explained in section 5 in the US manual and one of the more notable comments is "• The system may turn off due to strong electromagnetic interference". Interference from what? Radio, micro wave, cell phones, perhaps another cars FCW/RCW/BCW system?

Go figure.

Blind spot uses K band radar, the low power antennas on the car are tuned to aim specifically into the blind spot (side and rear) areas of the car, limiting their transmitting capability. However radar jammers, and other radar transmitters received by the antennas could be confusing the receiver. If you have ever used K band radar detectors you may remember experiencing false alerts at times. My guess is maybe other vehicles with radar electronics active, police radar transmitting, may have been picked up by the BSD antennas. Not being a communications transmission specialist I can't answer the microwave, but I don't think radio transmission or cell phone will overlap with K band frequencies. Communications experts are welcomed to chime in.

K band radar is clear up at 24GHz, WAY beyond any cell phone (figure max 1.8GHz). Ka band is even higher, up around ~35GHz.

Being in the presence of a strong legitimate K (or perhaps even Ka, depending upon the selectivity of the system) could 'swamp' the input of the car's system. As someone noted, there are jammers out there (illegal, but out there) that could certainly also have the same impact on the car's system.

At their much lower frequency, they wouldn't/shouldn't bother the car's system, but also to point out that GPS systems can be wonked by GPS jammers (~1.2GHz to ~1.6GHz, too. There's more of them out there than anyone realizes.
Newark Airport used to have a LOT of trouble with GPS jammers on the adjacent highway screwing up their operations.
