After heavy rain or a carwash, the door locks and lift gate don't work from key fob. And the vehicle says no remote detected and has trouble starting. After a day or two they start working again. It caused U0422 (invalid data received from body control module). On forums it says it can be water leaking into the vehicle and shorting out the BMC from either the HVAC drain or a weatherstrip somewhere. Now my rear passenger door locks don't work at all. Dealer wants to replace the actuators but can't find the root cause of the problem. Issue has been going on for over a year now.

After raining door locks on every door will not work. Won't lock or unlock, manually or by using the key fob. Something seems to be getting damp and shorting out . After a day or 2 the locks will work just fine when everything dries out.Seems to be a safety issue if I can't exit the vehicle. The rear hatch is the only door that works when this happens. What is the problem and the solution? This happens every time it rains. Had it to the dealer and they couldn't find the problem.

Gear shift notification problem. Unable to turn engine off after receiving "Shift to Park" message and the gear shift is visibly in the "Park" position. In addition, the doors would not lock. My wife was forced to stay in the unlocked running car in a store parking lot for 25 minutes, until the car just "turned off" on its own. Unsafe for a woman (or anyone) to have to do at 10:30pm. This puts drivers in a really vulnerable position. Vehicle taken to dealer Jan 30, 2023. Was told they were familiar with the problem.

Side blind zone sensors fail due to water intrusion - which is a known issue. A special coverage adjustment (#n172097060) was issued to repair this however not all vehicles are covered in the sca VIN search - and are not being addressed. My vehicle did not fall within the VIN search and experienced the same issues described in the sca. The day after the initial diagnostic and awaiting the part for repair I experienced a complete vehicle shut down due to the corruption of the sensor. I was not aware of this situation until after I researched the sca. This corruption is noted in the sca, however it only states part of the issues you may see. During the shutdown I was luckily not in motion, however, the corruption of the gmlan cause the airbags to disable, passenger airbag presence detection turned off, tire pressure sensor monitors were disabled, the entire dic shut down, instrument cluster shut down, radio and infotainment center shut down, door locks malfunctioned, power steering shut down, power brakes shut down, windows were disabled, and the vehicle would not restart until after about 15 minutes. There is no protection between the sensors for electrical interference and the gm lan. A sensor should not cause these issues, however it does, and it was also noted in the sca. This issue needs to be addressed. The malfunctioning sensors also cause a power drain on the battery, prior to the dic reporting the sensor failure, which is a fire hazard. Gm has not addressed the widespread issue of these faulty sensors outside the sca, nor the safety hazards of the lack of protection on the gm lan caused by electrical interference. If the vehicle is rear-ended, the sensors could cause corruption in the gmlan similar to the water intrusion issue - rendering the front airbags inoperable.
