My 2023 that I got in Dec 2022 started the roof knocking stuff and would knock over nearly every bump. I tried various lubes but they would last only a week or so. I did TSB 19-2374 for model year 2019’s (expensive lube) and more then a month later and not a peep. I could not understand how lube would fix knocks but it did.
Where did you apply this lube, like, exactly where, because it seems like I will have to deal with this myself. Now my car spent 21 days at the dealership, where they disassembled and assembled the thing two or three times, found out that nothing is broken, then performed a field test just to have the rattle start again on them. The third time, obviously with me urging them to give me the ride back, they assembled and drove back the car to me (about 150 miles) no rattle, I used it for two or three days, no rattle, then drove it to the city which is about 150 miles away and boom, it came back dancing and jumping. Now they want me to drive back to the dealership, 150 miles away from home, go on a field test with their mechanic and show them "exactly which rattle I am hearing" because after they had the car for three weeks because they couldn't get rid of the noise, now magically they think the noise comes from inside my head, and my wives head, and my childrens heads, and from inside the head of every person that gets in my car and gives me the "dude you got scammed, a car that sounds like that with only 21K miles is a *************" look. So, if anyone can help me get rid of the noise by myself, I will be forever in your debt.
