front parking sensor acting up

[djw88]

front center parking sensors act up sometimes.

ill be stooped and it will just start going off.

doesn't happen consistently.

 

no its not blocked by something.

no its not wet.

 

 

is it as simple as a bad sensor?

On my ‘16 I got the message in my DIC to check my sensors and (if I recall correctly) neither the fronts not backs worked.  

 

Took it it to the dealer.   One in front bumper was bad.   Swapped and I rolled.   All good.  Warranty.

I had one bad sensor on my 2017. Every time I would wash it or drive in the rain I would have issues for a day or so. I took it to the dealer and they couldn't find anything wrong, Went back to the car wash and got the same problem. I took it back and showed them the pics of the messages I was getting and told them to wash the truck. They ended up changing one sensor and all has been fine since.

Same thing was happening on my 16. Dealer found a TSB and reprogrammed. It stopped the issue, but I noticed that it no longer beeps with every increase of the "sonar" waves on the DIC. It only beeps when I'm in the final/"red" zone. Don't really like how it operates now.

well i finally figured it out

 

i swapped the inside sensors to the outside and outside to the inside. and now the right sensor is randomly going off. 

so i ordered a replacement from advance auto for $30 shipped to my door. $43 regular with 25% off and a $5 coupon.

 

oem one is like $140 so ill give the aftermarket one a shot.

Like that ^^^^^^^^^^^

So the one from advance is identical to oem both are bosch one just has a GM logo and part number. 

So no reason to buy the GM one for 4 times the price at advance Auto.

It is sold as BWD part number BWS46

Don't paint over paint like you have. If ill form a solid connection to the side of the sensor. Try scratching the paint off in a ring around the sensor head to fix it. Also water in the housing area is known to cause problems. Try taking the sensor out cleaning the housing , sensor and silicone ring and puting it back together.

Do you happen to have the part number they used? I'm having the same issue but am getting different part numbers!
