Seems it would be something to ask the body shop. I'd handle a situation like that through the insurance company. They're obligated to make sure your vehicle is repaired correctly.

 

I would think something in the repair process was compromised. So have them check it over since both the vehicle and repair work should still be warrantied.

 

Thank you for the replies. I am taking it in Monday. I was hoping that someone might know how this could be selected in the software. All the interior components of the old door were transferred to the new door. I don't see how this five second delay in opening the door could suddenly appear.

 

Don't expect 'new car' warranty to handle any repair if the service center knows the vehicle was wrecked and repaired. There are telltale ways they can notice someone else has worked on the vehicle even when you don't say anything to them. Talk with your insurance agent if the service center attempts to charge you for the repair.

 

Anyone have any idea of how to get rid of this five second delay? Thanks.

Does it have the handsfree option? That has a built in 2 second delay. Perhaps undiscovered crash damage or some wires crossed during the repair.

 

That might be a possibility. Thanks!

 

Thanks to divotdug, I found that the "hands free" feature is not working either. The light shines the logo on the ground, but moving my foot under the light does not open the door. It may be that a couple of connections were crossed when transferring the internal components from the old liftgate to the new.

 

Bodark: was a solution ever determined? This is near identical to my wife's 2021 Acadia with damaged tailgate replacement. Tailgate opened right away even with the minor damage and now has 5 second delay with new gate and transferred components. Only difference is the hands free feature works with its expected 2 second delay. Body shop took to local GM dealer and they said the 5 second delay was normal. Rubbish. Any more info on your solution is appreciated.

 

Yes.....in a way. I was told the same info as you from the GM dealer. It has been about four months since my liftgate was replaced. The problem has fixed itself. Over the course of the four months, the liftgate started opening without the five second delay more and more often. Now, it will only occasionally open with the five second delay. I have no idea how this could occur, but it has. BTW, my problem with the hands free feature was dirt on the sensor under the vehicle, which prevented the light from shining on the ground.

 

Thanks for the info. My wife's Acadia lift gate opens immediately the first 'open' of the day using the key FOB. After that it's a 5 second wait using any of the door switch, lift gate switch or FOB. I learned there is a control module for the gate itself that talks to the body computer and it can issue DTC's (diagnostic trouble codes) which can be read by a scan tool. A GM dealer is going to look at this in 2 weeks. I wonder if the software has a built in learning mode that, like your situation, over time, relearns it's OK to open the gate right away. Glad to hear your gate is working OK.

 

Please let me know if you learn anything new from the GM dealer. Thanks.

 

Thanks to my dog's day at the beach she left oodles of sand in the back of the vehicle, including several grains around the u-shaped hook the lift gate latches to. The bodyshop noticed many light scratches on the plastic trim around the lift gate latch mechanism where the latch and the hook meet. They adjusted the lift gate ever so lightly higher and the problem was solved. It opens right away every time. I'm guessing the delay was caused by the lift gate sensing extra pressure on it prior to opening (like someone leaning on it) and then flashing the lights to indicate it was about to open and waiting 5 seconds to open.

 

That makes sense. It is a motorized latching operation so it makes sense that any binding of the latch being too tight when mating might cause that issue.
Good work from that body shop tech then.

 

That is a smart tech. Thanks for the info.
