I don't know if it's company policy, but they don't usually charge under 3yrs/36k miles, after that they usually do...

Air Turbulence

Air currents, turbulence and layers of different densities cause refraction of the sound wave. An echo may be weakened or diverted to the extent that it is not received at all. Sensing range, accuracy, and stability can deteriorate under these conditions.

wchlin81 Hi, I am not sure if anyone is still following this thread BUT I've finally gone to the dealership to let them know my parking sensor goes off when there's nothing too close in front or back, and it goes off when perhaps a large truck or bus is on my sides but again nowhere close.

I went to the dealership, and they said they could not find a problem. THEN they charged me for labor performed "because Ford can't pay us anything that we cannot find to be a warranty repair".

I am sooo upset over this, to the point that I'm considering just letting the car die off, sell it, and never getting a ford again.

Any tips on this? Left a VM to Ford service person and no response yet.

Thanks

I don't think so because several times, the beeping started as soon as I put my car in drive in the morning and didn't stop until I manually turned off the sensors.

focus wht There are only 4 sensors for the front park aid. The 2 on the sides are for the self parking. and do not add to the beeping. Forget about the warranty because you will never be lucky enough to duplicate this issue on demand or lucky enough to have it beep while as scanner is connected. Just buy your own new sensors and swap them out and be happy. Once again the reprogram of the BCM and Apim has nothing to do with this issue no matter what they tell you but with an update to the vehicle . It is referenced on a TSB. There is no Tsb for the false Beeping.

I suggested they replace my sensors at the 3rd dealership I took my car to. There are 6 front sensors and 3 rear sensors. They told me that according to Ford policy, warranty work is only done when a problem is verified. Thus, they needed to figure out which of the 8 sensors were bad, if any. They then tested each sensor and updated the APIM and BCM for good measure. They found nothing wrong with the sensor system. However, it still acts up every now and then for me and is inconsistent. This is just my honest experience with this system. I think my case is rare but hopefully, anyone else experiencing this can glean some information from my experiences. Unfortunately, the fastest resolution to this is to buy and replace each sensor myself, or get a dealership to do the work with my money.

TitaniumD I have definitely had mine false alarm sometimes, but not the same problem as dragonpalm.
Mine will go off sometimes while stopped at a light next to a large truck. There must be some resonant frequency in the engine or exhaust system of certain trucks and buses. This alarm stops as soon as the truck moves.
I have also had mine false alarm when a sensor got wet or dirty. A little drop of water covering the gap around the center of the sensor is all it takes sometimes. This usually happens after leaving a carwash, and will go away very quickly when I start to drive.
My falses are also usually not the fast beeping or continuous beep, I usually get the slow beep as if I am farther away from something.
