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.

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.

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!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Indeed a proper drain tap or drain valve with adapter that has a hose on it that opens up the valve as the adapter goes on is a slick setup and have that for certain highway tractors etc and other equipment that came from the factory with a tap but this L8T is pretty darned good other than me doing it on the floor and easy to touch hot exhaust and am not as agile as I used to be !. If I really want to pull a hot filter on an engine I will use an insulated set of thick neoprene gauntlet gloves but I am not in the hurry I used to need to be so things are done more relaxed and in theory somewhat safer ... I think LOL.    And as I mentioned the unique shape of the Amsoil 1 quart containers, while they might not work as well as an offset pour spout container for some awkward engine location applications, they are working a lot better with my Lisle funnel kit because of how they prop up on all four corners when upside down resting on the rim of the funnel where the typical quart container would never stay put without holding onto it.

      Clunk when coming to a stop... driveshaft/slip yoke? Mechanic couldn't recreate it

      By mrbflat · Posted

      Well, I just hit 100K a few weeks back, and I can honestly say I have not had any major issues with my '21 5.3 Crew cab.  I have done most routine maintenance, oil changes, air filter, tire rotations, and a transmission drain and filter change (not even a full flush).  A couple of months ago, I started experiencing the dreaded CLUNK when coming to a stop, sometimes hard enough to literally push the truck forward! After researching here and in other forums/youtube videos, etc, I was thinking it's the slip yoke. I finally had a chance to take it to my local mechanic today, and he was not able to recreate the issue.  Amazing, since it does it nearly every time I drive.  He also said he can't simply grease my slip yoke/driveshaft splines, because I have a 1 piece driveshaft.  I am not sure what else I can do.  Has anyone else had this issue or have any idea what else it could be?

      This is where the Fumoto drain valve comes in handy.  No mess and able to change oil hot, like right off the interstate hot.  Flows nice and you can direct it into a container. As for the oil filter, I use an old dixie cup or plastic one from McDonalds. It contains the oil as you pull the filter down and not all over your hand.

      Which 2027 engine will you choose?

      By Black02Silverado · Posted

      Well, if it did change from lifters to rocker arms, at least it would be easier to fix as they fail.

      HighMileage oils or stay with Dexos 1 ?

      Doesn't hurt to try.  It's my understanding that you have to run it at least 4 or 5 oil changes for things to get clean.  Think about it, your engine didn't get dirty in just an oil change so over time it will slowly clean. It's the safest way to do it and not have seal issues.      I remember  a product that came out a long time ago, AutoRX, it was an additive you put in the oil and then drove for 3k miles. Some saw improvements and some didn't. It was suggested to use a non synthetic with it at the time. Same observation, use a couple oil changes and give it time to work. It also stated it worked best if you could drive on trips to keep the oil hot.  I'm sure if you ask AI it could tell you all about it.
