Adaptive cruise control issues after recent mod

[family4tlasroadtrips]

So, I put in an aftermarket sensor/module on my 2019 Atlas, and now my adaptive cruise and collision warnings are acting up, they're either late or just not showing up at all. Even the auto-brake isn't working. Has anyone else run into this and know how to fix it?

Yeah, that's likely the issue. If the module isn't OEM or wasn't calibrated after install, ACC and AEB will act up. You'll probably need to get it re calibrated at a dealer or a shop with the right equipment.

@family4tlasroadtrips Yeah, aftermarket modules can really throw off the sensors. Best bet is to have a dealer or specialized shop recalibrate everything so it works properly.
