I have a new 2019 Suburban and when it below 20 degrees the lift gate won’t open. I know that there is a “lockout” around 4 degrees F to prevent motor damage but this thing won’t open when it’s 20 degrees. My last Sub also had this “feature” but at least it would work if the interior was warm and if all else failed you could just pull the door up. I can’t seem to open this door manually when this happens. That puts me out of a tailgate for basically the entire winter as I live in MN and 20 is warm. Can this temp set point be altered somehow? Any suggestions? Thanks.

If the liftgate does not open because of cold weather, the manual says to "select OFF on the liftgate switch".

Turning the liftgate switch to off does not fix this problem. I have a 2018 Suburban and its doing the same thing when below freezing. Any other thoughts on this would be appreciated.

There may be more going on than cold weather, my manual does not give a temp and it does say the word 'may'  I would check the Liftgate module with a scan tool and see if there are any issues in there. No codes would be appearing on the dash. I live in Canada which regularly gets below 0 F, and i have never had any issues using the power lift gate. Sometimes I would have a problem with the sensor for your foot when the ice gets under there. The fob usually takes care of the opening. It may be different as i have the 17 Suburban with Premier Trim level so they may have made changes in the 18 and up.

@cjpwalleye @SUB2018 Did you get any resolution on this issue?  Our 2017 just started doing the same thing, if its 25 degrees outside, we are not able to open the tailgate.  Turning on or off the power liftgate feature does not change it.  In a heated garage it works fine.  Very frustrating, i can't seem to find any info on this problem.

GM has a Service Notice - If it get to cold , turn power off , and lift tail gate manualy, Make sure you hold it up, so it wont drop on your head.  This was on my 2008 tahoe .

Old thread but clearly still a problem. I have a 2017 Tahoe and experiencing this is SC with the unusually cold weather. Console switch in off position, lift gate will unlock but will only lift a few inches manually before resistance is felt. Initially noticed at about 9°F and worked normally earlier/warmer in the day. Over freezing today so will try and see if it is resolved and will let you know. Curious if putting it in manual before the freeze would have helped. Any advise form colder regions to help a frosty southerner would be greatly appreciated 😊.

Turning the switch off before it gets to freezing does not change the problem.  Our 2017 Yukon XL has the issue as you describe above, and the console switch makes no difference whatsoever.  For us, last year it worked fine, even down to about -5 F, this year, 28 F and it doesn't work, have to stuff the Yukon in the garage and let it warm up.  Since we can't open it manually, which would be fine, its really hard dropping the kids off at the ski hill right now.

 

Any guidance would certainly be appreciated before I start swapping out parts randomly

Yea that blows. There must be a work around for this “feature.” You’d think there would be an alert or a light when the computer is stopping the lift gate from working. At least then you would know if it’s broken or just temporarily disabled. Dash tells me that there may be ice on the road but not that I can’t use the lift gate… Ours has worked fine now that we’re above freezing but would love to know to know if there’s a fix. Thanks for the reply.

Well, in case anyone is interested, or runs into this later, it was the lift gate actuators, which are also the spring arms.  They cost around 300 bucks, from the dealer, and was a fairly simple replacement, I think it took about half an hour start to finish.

2020 Yukon purchased used @120k miles. At 125k temperatures hit a low of 19 overnight for two nights in a row.


After the second night lift gate would unlatch and latch but not raise.

 

after researching and about giving up and taking it to the dealer, miraculously started working again after parking in the sun where temperatures approached 40 around noon.

 

changing the dial in the headliner had no effect. Temperatures are normally not that cold so I’m assuming it was temperature related.

 

Not good for those in colder climates, However I found no YouTube videos or forums that provided any other answers except to attribute the problem to weather conditions.

 

GM is no help when google is used to find answers. I’ll assume this is the least of GM’s concerns considering all the other problems associated with this make model year

Had the same issue on a 2017 Tahoe, my initial reply to this post is above in Dec of 22. Once the weather warmed up it was no issue… Until they failed to actuate at all in June of 23 even with warm weather. This could be an indicator that the actuator is beginning to fail, at least it was for me. Bought a pair on Amazon for $90 (yes both). Easy install and have not had any issues even in the very cold weather this year. Hope this helps. Amazon description below, YMMV.

I have a 2022 Yukon with the same issue. I actually found that there becomes an ice/mud(from dust) build up at the top of the trunk opening. Once I cleared the ice and mud from around the electrical harness, it started working. Seems like a design flaw to me

      OCI, not when but why?

      By Chuck FB · Posted

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.

      Looks nice. I still have my 2000, 1500. Bought a 2025, 1500 for retirement. Feels solid. These trucks have a bad rap on the internet. My brother has a `24 1500, 5.3 with 52,000 miles. No problems at all. Mine hasn`t either but mine`s only at 12,700 miles. Have seen some of these things with 100,000 miles with no problems.
