All so common these days.... ok .. 20 years or more.
plastic body parts, Glue attachments.. even metal to metal... plastic interior parts.. dashboards... and on and on.
they rely on the threads to Cut into paint overspray... out of warranty in 3 to 5 years... will work till then. if not dealer will deal with it..
latest story I have... Ohio State highway police car pulling over a Akron police car at night.. NO rear lights of any kind.. and the Car was 2 days old.
grounds were never attached in the rear half of the car... 9 black wires not attached at 2 points...
or motorcycles with bad ground connections at the spark plug coils... for 4 years of production. paint in threaded holes
