On my 2013 QP (model year 2012 carryover) the right-front-outer parking sensor somehow got pushed inwards - and fell down inside the front bumper. I did an online search and from other's experiences it seems that the front bumper must be removed to gain access. Well I'm happy to report that is not the case - you can access the parking sensor by removing the headlight assembly. To do this, you need to remove the right-front wheel, and then the wheel well liner, then a support bracket. Once all of these items are out of the way, you can remove the 3 bolts securing the headlight assembly, and just slide it back out of the way. Then working from the front of the vehicle, you should have access to the parking sensor. I hope this helps others out there who need to access and/or replace these sensors.
