Got a new 2018 Atlas and the ACC (front assist sensors) keep giving a fault and shut down. Have made one trip to the dealer so far. Trying to contact them again to let the know it still isn’t fixed. The dealership it was purchased from is about 65 miles (one way) away. Has anyone had a problem with the ACC?
It works great on my Passat.

Thanks for any input.

So, I’ve had my Atlas almost a year and had it in for faults a few times. The first time the front radar dropped its calibration, the second time there was an evap leak fault but no leak detected, the third time it was a bad battery fault, there’s one more I can’t think of off the top of my head but each time the dealers had it for the whole day.

I don't suppose you had something covering the VW Emblem in the front? That's where the sensor is.

So my 2018 Atlas is at the dealer now saying I need to pay $395 to have the front radar recalibrated.
On a recent road trip, in a long run of interstate stop and go traffic the dashboard lit up yellow for no apparent reason. Front crash monitoring out, ACC cruise control, inoperable.
We’ve only had the car about 90 days. Dealer says we must have “hit” something but there is no evidence of impact except a small abrasion on the lowermost corner of the passenger bumper (where it isn’t even painted, but just black plastic). Looks like someone lightly touched a tall curb or something.
Only my spouse and I drive the car and again, the fault happened suddenly while driving down the interstate.
They’re saying it’s not a warranty issue due to the fact that it’s been knocked out of calibration. The radar and the grille and the bumper show no other signs of damage,impact or alignment issues. Does this sound right? Could the front radar have been knocked out of calibration by something so minor? Or could the computer have just created such a fault by just freaking out in heavy stop and go traffic!?

I doubt it. My wife had a UFO hit her driver side bumper and kicked in the driver bumper sensor and damaged the black wheel well trim, etc. We had to replace the black bumper, etc. but no paint damage. Other words, our ACC worked just fine during the two weeks we had this damage. The Sensors went off like crazy so we deactivated it, but the ACC still worked as its supposed to.

I would fight them as best as you can, but we are the small dogs when it comes to warranty repair. The ACC sensor is in the VW Emblem I believe, so not sure how a bumper hit can cause this to be re calibrated. Good Luck.

Yes! New lease vehicle and first week out the "ACC is unavailable". And a big yellow "!" appearing in a triangle in the center dash display. I took it to the dealer service. They diagnosed and said the front ACC unit was bad.

They had to special order the part from VW (2 days). They put the new unit in but they we not able to get it to calibrate (1 day). They contacted VW and they recommended that they replace the front grill. Special order (3 days). That appeared to work. I picked up the Atlas and drove home (8 miles) with the ACC working fine.

I parked the car and went out to drive it a few hours later and got the "ACC is unavailable" message and the big yellow "!" again. Unbelievable. Thinking of just having it disconnected so I don't have to look at the warning light anymore, and just be done with it.

At this point my new car has been in the shop equal to the time I've had it to drive. It's a tough choice. It feels wrong to spend $45K on a new car and not have it work perfectly but it also feels wrong to make payments for a car that's sitting in the shop. Plus, the inconvenience of going back and forth to the dealer on the NYC subway.

I was just now searching the internet for any info about this problem and came across this website. I have not found anything else yet. Has anyone else had a similar experience or have an opinion on what I should do next?

Just drove my fully loaded sel premium atlas for 59 miles on the highway. Going about 70 mph. Once i got into the city and slowed down. Acc stopped working ... big yellow ! In the dash. Acc unavaiable.

Brand new atlas. Drove it home for another 50 miles. With no cruize control. I cant believe that acc doesnt turn off and allow you to drive without it.

Well i guess i get to go to the dealership and see whats wrong. And spend some time hanging out.

I was hoping. Maybe. Turning the car off and back on would do the trick.

Maybe a moth or bee hit my VW sign to hard and broke my sensor ? Lol

However nothing was on it. So must have been a bounce ?

We have a 2018 SEL Premium with about 17k Miles and are having issues with the ACC and the lane assist/keep Systems. My dealer is telling me it’s due to the car being out of alignment... I’m not feeling good about the service advisors explanation.p, but he says the toe and Camber is off... so the vehicle needs to be aligned and then the sensors/cameras need to realigned.... it’s over $400 for both services as they say it’s not a warranty issue. Any help or possible more explanation would be expected. I’m going to fight with the dealer a bit and get vw involved f the dealer doesn’t help. We’ve had sensor issues since day one as well as a bunch of other small issues along the way. Frsutating for a 50k+ brand new vehicle. Glad we leased it.... couple years and it’ll be all there problem.

They claim that an alignment issue is causing the ACC and the lane assist to shut down. No cruise control, no lane assist/keep. The vehicle was in a small fender bender 4+ months ago, Fromt bumper cover replaced, no other damage, no trip to dealer, no issues with ACC or lane assist afternoon pickup. Problem began 2 weeks ago, dealer gave us a loaner, but has now had car for 3 days, claiming the alignment machine is having issues. Feel like e are getting fed a Line here. Not too happy.
A mechanic friend of mine (bmw not vw) stated it could possibly make sense if the ‘steering wheel alignment/position sensor’ and the ACC are connected somehow. I’m probably describing the sensor he spoke of incorrect... but he still said alignment shouldn’t have an issue, and it should be warranteed....

Accident could certainly be related in some way. Sensor is under VW emblem on grill is my understanding. Camera is other component. What errors are you getting beyond "they don't work". Again, alignment of the f. end woudl have to WAY out to even remotely impact this. There have been plenty of folks claiming issues with this over on vortex. The accident is going to work against you here if you mentioned it/they figured it out.

Hi all, I bought a 2018 Atlas in March 2018. I'm towing a camping trailer with it. The second time we went with the truck the accs went off. I brought the truck to VW and they recalibrate it. Or rien works Well for a couple of weeks, up To the moment we go back in camping towing the trailer, the acc went off again, that time I brought banc the truck to VW they had it in thé shop for a week and half, changed the front radar twice, but the calibration was still not holding on. They had several talks with Tech from VW canada To finaly discovery that the problem was in the programmation itself. The company that provide the acc system Odis bad To build a new programation from scratch. It took 2 month To do it and when they got it vw called me back, took à appointment and change back (again) the radar and acc system with the new programation. It's been two week now ans seems To be working Well. I just wait for the next time I Will be towing the trailer To see if it old then. It is à known problem et from VW and Odis (the comptant providing the acc system) so it is under waranty no one should be paying for recalibration or anything link To that problem.

ACC Not working from day 1

Well I wish I had read all of this prior to purchase. We were excited to take our 2019 home. It had 3 miles and on our way home we noticed a little orange icon with an ! symbol. Drove the car 5 days around town, to work, maybe 200 miles.

Roadtrip time - get on the road and cruise control won't engage. You turn it on, the little orange icon comes on. Now I know what it is! Then when we press "Set" we get a message, "ACC UNAVAILABLE" then we move from screen to screen and see "ACC De-activated" so we call dealer. They said they had never heard of any issues and we should be able to "activate" by going to settings. No option there.

Very, Very frustrated with this technology and atlas. I road trip at least once a month, its very frustrating to drive 400-600 miles at a time with no cruise control!

I guess it needs to go back to the dealer. I pray they can fix it.
