Great Question, Harold. I took a look at the Draw-Tite Sportframe Trailer Hitch Receiver # 24942 and it looks like you should be fine.
The only thing identified is that the underbody panel(s) and/or fascia must be temporarily loosened or removed, trimming might be needed to reattach panel or fascia, and you will be required to temporarily remove the bumper and fascia, as well as do some trimming to the fascia for installation. view full answer...
The Draw-Tite trailer hitch # 24942 for your 2018 Acura TLX has a 1-1/4 inch receiver. This is a Class I hitch so a bike rack will need to be Class I rated. Looking at the 1Up Quick Rack they state it fits 1-1/4 inch and 2 inch receivers but they do not mention if the 1-1/4 includes both Class I and Class II hitches or just Class II. view full answer...
