Problem Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2018 Volkswagen Tiguan and Tiguan long wheel base (LWB) vehicles. The nut that holds the lower ball joint of the front wheel on each side of the vehicle may be loose or improperly tightened. Risk A loose or improperly tightened ball joint nut can result in the separation of the lower ball joint causing steering, traction or other stability issues, increasing the risk of a crash. Fix Volkswagen has notified owners, and dealers will replace the nut on the lower ball joint and, as necessary, clean the thread in the ball joint, free of charge. The recall began May 30, 2018. Owners may contact Volkswagen customer service at 1-800-893-5298. Volkswagen's number for this recall is 40N4. Note: owners are advised not to drive their vehicle until the recall repair has been performed.

Two numbers, one recall

Every safety recall carries two identifiers. 40N4/40N5 is the number Volkswagen assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 18V324000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.

Check one specific vehicle

Both lookups check a VIN against the manufacturer’s own list and say whether the repair is still outstanding on that vehicle.
