The GMC Hummer EV Pickup is a complex and highly advanced vehicle, however despite the vehicle’s state-of-the-art tech, some owners have reported problems with a rather simple and straightforward component on the battery-electric truck: door lock and window switches.
According to a recent post on the GM Techlink service website, some 2022 GMC Hummer EV Pickup owners have reported that the vehicle’s driver-side door lock, window, and mirror switches suddenly stopped working. This condition may be caused by a leak in the A-pillar, which can allow water to enter the inside of the upper A-pillar and lead to corrosion on one of the in-line connectors for the driver-side door switches.
To remedy this problem, GM suggests dealer technicians open up the in-line connector in the driver’s side door (labeled #1 in the image below) and use a mirror to inspect the inside of the connector for corroded terminals. At this point, the technicians are instructed to clean the terminals and/or replace any damaged terminals as needed.
In addition, GM is instructing technicians to perform a water leak test on the A-pillar of affected vehicles. To do this, the technician will remove the air inlet grille to locate the seams where the A-pillar merges to the plenum panel and inner fender, re-seal the seams, and test for leaks. The image below shows a technician properly reapplying GM’s suggested sealant to this area to prevent further leaks.
GM also started a Customer Satisfaction Program for certain GMC Hummer EV Pickup models earlier this month due to an issue that may cause the high-voltage connector for the battery pack to corrode. This problem involving the driver-side door switches is not being addressed via Customer Satisfaction Program, however GM has issued a Service Bulletin to address the issue. A complete list of Service Bulletins for the 2022 and 2023 GMC Hummer EV Pickup can be accessed via the National Highway Traffic Safety Administration’s website.

Cause it’s a POS
A $100.000 rusting POS.
celestiq customers can expect the same “luxury” experience, brought to you only by gm.
I figured that maybe you now need a subscription for them lol.
Leak? With that 16-part removable roof??? HOW?!?!
Wow, who would have thought, huh?
Nothing new here.
Standard lack of quality gm is known for.
These things will happen to the celestiq as well, because gm is not capable of building anything reliable or of competitive quality.
They were forced out of europe because of issues like this.
Surprising since they’ve delivered like a whopping 500-600 max at this point. They’ve all but stopped deliveries since July+ it seems…
Production is “up” to twelve a day.
Yep 12.
I can see how that will scare the competition.
LOL
And look at that dodgy build “quality” where they are applying 10 cents of cheap sealant.
And they are going to take over the Rolls Royce market?
LOL squared.
