2016 Volkswagen Touareg Complaints

There was a big rain last week locally. I drove through a couple big puddles but nothing that's super uncommon for the area. Almost immediately, my car's electric components started going crazy. ACC stopped working completely. Lane assists aren't working. There was an error that I think was shift lock, but it was red, and the car was driving really weird.

Electronic Parking Brake lever light was flashing and dashboard showed parking brake error message. Drove car to VW Dealership, which diagnosed problem as likely bad Parking Brake Control Module (Part J540). Dealership ordered part, and stated I could drive car home. Within 1 mile of dealership, parking brake engaged automatically abruptly slowing car and error flashed on dash stating "Disengage Parking Brake." Pulled over, turned car off and back on, which disengaged parking brake. Returned to dealership and left car until it could be repaired. Had I been on the interstate traveling at a higher rate of speed, this may have caused an accident.

NTHSA folks, Two months ago, I began getting an "Error Airbag" amber warning in the Touareg's driver-information display. I visited the dealer and was told "the airbag module" (volkswagen-2016-volkswagen-touareg-control-module-7p0959655g08p) was the issue. I was told they'd order the part, only to hear back later: "There are none in the U.S. and it'll take 5-8 weeks to get one from. Europe." This has since been updated with "We have no idea if or when this part will be available." As a consequence, it appears I must simply wonder whether the airbags will deploy if needed, which strikes me (no pun intended) as irresponsible on VW's end, particularly since it concerns a safety-related failure. Indeed, if this part is so unavailable, it would seem that either many owners are experiencing the same problem, or the problem is extremely rare. (I believe it's the former.) Anyway, I bring this to NHTS' in the hope of getting clarification and/or assistance. And ideally helping find a way to...

2016 Touareg was towed to OStein VW service after engine would not accelerate and ran rough when got onto the interstate. OStein VW diagnostic was water into the air filter that got into engine and now need to replace engine block because of water getting into the air filter from the rain drain system system getting clogged for the Touareg. VW Service says can hear engine valves chattering. I see at NHTSA that at least 60 other complaints have been filed about this problem of water getting into the air filter.

There is an ongoing issue with the drain from the air cleaner box clogging and water collecting in the box and then being ingested into the engine. On other occasions I had drained water from the box and changed the wet air filter to a dry one. Today (5/26/2021) I pulled out of my driveway and car started stalling. I got a transmission fault notification and immediately returned to my home. After raising the hood I noticed a noise from the left side of the engine bay and checked the drain for the air cleaner box. It was of course clogged. I opened the air cleaner box and approximately 6" of water ran out of the box. I restarted the engine and no longer had a transmission fault but an engine management warning. The engine while running was running roughly. I contacted the nearest VW dealership and they stated that this was a known issue, that there was no recall, that VW had come up with a "fix" for the issue and that, of course it was not covered under the powertrain warranty....
