4pcs Reverse Backup Parking Rear Bumper Park Assist Object Sensor 15239247 25961317 25961321 25962147 for Cadillac Buick Chevrolet Chevy GMC

The sensors may be OEM, but they are cheap af. They only Communicate uni-direcrionally. They work, but you get constant "service park assist" messages.Will not trust this seller.EDIT: Mistake on my part. They will work, but only if you put them ALL in. I was trying to just replace two sensors, but they would not communicate with each other. After putting the other two in, they work just fine.

accurate identification and fast shipping

They do not work i put another orginal sensor and it worked but computer says short to ground changed all four and still having issue went with oem and service light went away cheap asf stay away finally got my truck back from painting and installed and dont work

Well I had the warning message on the dash, ordered these. They cameQuickly, packaged well. The day I went to install them…. The old one already on the truck started working (go figure). So I haven installed them so can’t say much else. Watched several you tube videos on how to install them looks straight forward enough.

Bought for my 09 GMC Sierra, was delivered super fast, super easy to install and saved me $750 because everywhere else I looked they were $200 EACH!! would HIGHLY recommend

I used a stethoscope to verify the sensor was working but am still trying to remove the " service park assist" warning on my Silverado. so the sensor is working as it is supposed to, but the truck isn't accepting it fully. I tried pulling the fuse and the battery cable but the message still won't go away. I pulled the fuse to disable park assist. I could have just done that and saved the money for this product and been ahead of the game. Not the fault of the product, but letting others know.

They worked perfectly and were very reasonable price compared to oem.

I was happy how easy these sensors were to install in my Chevy Duramax. they work fine.
