Not true, because you don't know the EXACT reason your GX is on hold. There isn't a dealer out there that has that info. There are rumors circulating about sunroofs being the cause, but still no actual concrete official reason.
The GX, according to the Toyota/Lexus recall filing, is not part of the recall. In order for the GX to be affected, motors built in 2022 would have to still be available to the Tahara plant for install in the early GX builds. If that actually happened, then it could be argued that Toyota/Lexus is now a whole lot more incompetent than anyone realized, and would be in danger of losing a whole lot of loyal customers.
