My 2019 ltz Duramax is having a meltdown. The door locks are going crazy. Driving down the road and it’s click, click, click, etc... non stop. The only way to stop it is when the truck is off and I hit lock on the fob or hold the lock button in the lock position while driving. Dealership wasn’t much help. Anyone have anything like this happen? It’s the 2nd time for me. 1st time lasted 10 min about 3 months ago. This time it’s been hours

Ok im going to assume some stuff. Does it stop doing it once you put it in park? does it only do it when your going down the road?

It might be one of the door open sensors. it thing that the door is opening and closing so fast that it doesn't display but it tells the door to lock.

You might want to crack each door open a little when it starts acting up again to see which door might be causing it. if it goes away with one of the doors open then you know at least its affiliated to that door.

It will do it in park, drive shut off and running. The only way to get it to stop is with the truck off and hitting the lock on the fob. I’ll go out and try the opening doors, but I don’t think that’s it. I’m very grateful for your input!! I’ll keep up and let you guys know what I find. I will say, both times it happened it was raining. That might have something to do with it.

Force those a-holes to go for a ride with you or have a passenger video the event for you

 

lol! I know! I feel the same way about most dealers. I don’t have to bring them for a ride, it will do it parked running or shut off.

I know this is a old post , but has anybody have any luck finding a solution? My 2015 2500 started doing this , I check each door and I've unplugged every switch to test , when I remove the fuse for the bcm for power locks it haults it but you can still here it trying to work, when I unplug the pink connector on the bcm under the dash it stops doing it , I've checked my wires and they look good , I've taking the batteries out of my key fob and cleaned all battery post , could it be the immobilizer in the roof or bad bcm?

      Sure, but they do have some affordable options like the Trax, Trailblazer, Envista, and Encore. Some of these have a cheaper base price than the Civic, though the fuel economy isn’t as high. The main problem is that people WANT the highest trim with all the goodies and finance for like 7 years. That’s how ppl “afford” the more expensive vehicles.

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.
