Anton Yelchin -- Recall Repair Never Completed

Anton Yelchin's Jeep Grand Cherokee Laredo never got the fix that very likely could have saved his life ... TMZ has learned.

According to NHTSA docs, obtained by TMZ, the recall on Yelchin's SUV had not been addressed -- meaning he was susceptible to the PARK problem with the shifter.

The recall notice went out on May 14, 2016 ... and says, "Drivers may inadvertently fail to achieve the PARK position before exiting."

As we've reported, the problem is a driver might think the car is safely parked, when it's actually in neutral.
