Are you guys referring to the underbody covers, ecu covers, or was there a proper engine cover under the hood? Now I'm curious
Engine covers - those were removed pretty much across the board and other manufacturers are doing the same thing (unless in some cases you get a "better" version of the car - ie. Grand Cherokees have no cover unless you order a Summit or an Overland)
Hood shrouds have also been hit or miss - our '19 Edge ST was a tad quieter than the '21 ST as the hood had nothing underneath it - just bare metal.
I really wish that I had kept the Ford Performance manual sleeve from the '19 ST...
Then again, at least the cars didn't have the nonsense from our new '22 Toyota Highlander Platinum. The back end of the steering wheel had broken clips, passenger door had a failing latch on first pull after unlock, the rear door trim was not glued/attached and was coming off from new... there was also something banging behind the dashboard between the steering wheel and the door... noticed it when pulling out of the dealership but we had a 4 hour drive home and didn't have the ability to just say "take the car back". And if you guys who hate your Explorers for mechanical issues are upset - I had the valve seals spitting clouds of oil on start after just 3k on the odometer. Worst car ever. Have never hated a new car bumper to bumper until I got a Toyota Highlander...
.... so here I am still with Ford!
Suffice it to say, it is now luck of the draw with every car manufacturer
Except for Hyundai and co. - ie. Kia. That's just a flame waiting to be lit... pardon the pun.
