I had a bad seat memory control module - dealer needs to run a parasitic battery drain test - my seat control module tried to communicate 290 times over a weekend at the dealer and drained the battery - GM just came out with a newly designed module - installed and no problems since.

Had the single Seat Control Module under the drivers seat replaced with new designed module from GM - dead battery after 3 days due to Seat Control Module trying to communicate 290 times over two days and draining battery - stopped the battery drain. Not clear what your problems are ...

New Seat Control Module installed yesterday and put on analyzer overnight to check for any battery discharge - none - so just picked up my truck. The new seat control modules should be available if anyone has this problem. GM had issued a GM-Techline notice in June 2020 about the bad seat control modules and they are just now available ........... lots of supply/manufacturing issues around the world for GM. Local repairing dealer gets an A plus !

New Seat Control Module in Cincinnati on Friday and on its way to my repairing Dealer north of Detroit for possible repair on Monday and then a day or two to make sure that it is the only cause of the battery draining to dead over 3 days ..............

Am I the only one with a Bad Seat Control Module ? Bad module was draining the battery - tried to connect 290 times over a weekend at the dealer and drained the battery. GM now updating module and is shipping the new part to part warehouses. Truck has been down 28 days waiting on the new part to get to the dealer for repair. Dealer would not release truck with fuse pulled on bad seat control module nor install a "new" old designed part - had to wait on the new part. GM had 240 new modules produced on the first run.

Newly Designed Seat Control Module to be shipped first week in March. Hopefully they kept my new battery on a charger or disconnected while truck was sitting and not just left totally dead for 10 days - check on this Monday.

GM and their manufacturer has produced 240 new design Seat Control Modules and my truck should be one of the first to get one. No firm timing yet.

Thanks Kent, yeah, I realize selling dealer can not really do something except maybe a push, but did say phone calls to the customer service center is the best approach to elevate the case. Repairing dealer looking to see if pulling the fuse will get the truck back in service - pulling the bad module will probably set some codes ........they are going to look at it and let it sit overnight to see if it still discharging from anything else - seat module is the most likely suspect but need to verify. Thanks for your input ......

Talked with repairing dealers "Customer Experience Manager" and are upping my lack of part to fix my truck to the GM District Manager. Called Dealer at which the truck was purchased and asked for a push from them - did not trust the truck to go 35 miles to them due to jump starting particularities - high amp flow on charge before jump. Selling Dealer had me go back to GMC.com Customer Service on call in - ended up being on text. Gave them my reference number and they will get back to me in two business days. There are many trucks that sit at the dealer waiting for a part - like two months. I could request a loaner Pickup Truck as the next step. I was told if it sits for more than thirty days GM would help pay my note on the purchase - mostly cash, trade in and tiny note ........... not interested. I am going to see where this goes, but a new truck with the correct part would be my chosen direction - exact same truck and swap them out ................. Day 15 out of service today !

Nope - new part number is 23338340 and the old part number is 13517130 and the new part is not available from GM - GM online part stores have this reversed and wasted a bunch of time finding a 13517130 at another dealer which was in stock, but what you want is the the part number that fixes problems with the old unit - not working and/or draining the battery. No timing from GM other than a few days out for 23338340 - a $100 part has taken my truck out of service for 15 days so far. Don't understand why GM can't pull parts from the assembly plant to get our trucks back on the road ......... Grrrrrr !

Still searching for a seat control module - some more data on Power Seat Control Module causing dead battery. What are the symptoms of a bad Power Seat Control Module? Symptoms of a malfunctioning power seat control module might include the seat not moving in one or more directions when the switches are actuated, or the seat not moving at all. On vehicles equipped with seat heaters with controls mounted with the power seat controls, inoperative seat heaters may be a symptom of a faulty control module. Also, in some cases, seat setting memory loss may result from a bad seat control module. Occasionally, a dead battery or a blown fuse can be a symptom of a bad control module as well. Seat Memory Control Module - GM (13517130) List Price: $168.92 You Save: $58.96 (34.90% off) Sale Price: $109.96 Make sure this part fits your car

Checked multiple online GM part sources for the Seat Control Module - most show the Seat Control Module - but none are in stock and are back ordered and GM as no expected release date. So I wait until GM comes through with a release date and a replacement part - not just plug and play, has to be programmed. May be easier to just order a new truck ..............

Have a 2020 Sierra 1500 Denali - Purchased in December 2019 - best GM truck I have owned. First week in February attempted to remote start - nothing; then changed battery in remote - nothing; go out to the cold truck and manually unlocked - totally dead - 3.5 volts; charged overnight with my regular battery charger - amps pegged out on full charge, switched to 2 amp slow charge and pulled 8 amps ??. Left overnight and got in to bring to dealer - DIC showed "Extremely low fuel level" - I thought that maybe I did not turn the truck off and ran all the gas out - got my 6 gal can of premium fuel and topped it off - took 4 gallons ?? Started and took to dealer - fuel warning gone, but CEL on of course. Sat a day at the dealer - they looked at it next day and came up with a dead cell in the battery - replace with new battery and took home to live happily ever after. Used the truck next several days and sat over the weekend. Went to start on Tuesday and dead again - charged on low setting overnight - 5 amps on 2 amp setting ?? - dealer put "analyzer" on the truck and saw a parasitic discharge for a while and then went away. Kept on machine over the weekend and Seat Control Module wanted to communicate 290 times by Monday morning. Ordered Seat Control Module - 2 days later, GM does not have a seat control module in stock and is backordered. GM is now looking around the country for a Seat Control Module .......... I know it "talks" to the Body Control Module (I see a couple of those going bad too) ..... waiting to see if GM can find the Seat Control Module. Have a loaner small SUV from the dealer, but truck is my long distance family visiting machine ............

Not easy to change the starter on the road. If you have driven it for a while it should be fine in the cold Canadian Rockies. If you are still worried, just put the new part number starter on now and have that peace of mind.

When my old non functioning starter was pulled off I checked out the seal very carefully and found it to be very well sealed - the dealer did try an overnight bake out procedure with this starter and it still would not work in very cold conditions. I think that the moisture was sealed in at the factory in Mexico and is causing the problem. If these style starters from Valeo, produced in Mexico have defective seals that allow moisture into the solenoid that would have produced many more failures and on some older trucks too - again, no data, just my guess. I also think that over time any moisture present in the affected starters does diffuse out at the high operation temperature of the starter when on a running engine for a longer time. I would bet that a southern truck with a potential defective starter due to sealed in moisture would not have a problem if driven for a while in the south and then came up north with the frigid conditions that we can have - again, just speculation. I would have loved to have pulled my defective starter apart to check for moisture or grease. My new starter of the same part number has performed flawlessly with many low temperature starts. One owner had a bad ground cable that caused a no start condition - clean up and tighten the ground - start Several owner have had high resistance in positive battery cable to the starter - change cable and - start Some owner have had loose connections at the battery to cause a no start - tighten up and start One owner had a defective battery - change battery - start The dealer can run through these 4 items very quickly and then just put the new part number starter on and DONE and out the door in 4 hours - which is what I did - after the bake out procedure was tried with an overnight stay at the dealer ........... they just need to change the starter and I would have saved a trip to the dealer, the rental car (they paid), back to the dealer, pull the starter, wait 4 hours and then go home ............now happy.
