“Hello Nhtsa, It is a brand new car, while we were driving on the freeway, all off a sudden, we hard noisy drive, eventually smelled plastic. When we saw under the Underbody plastic shield with clips loosen up and it is handing half on the road. we were scared and it could even fire up the whole car as we smelled a burning smell. I called Toyota Custer service a couple of times and reported the issue. again called towing company took to the dealer. …”

NHTSA complaint #11451126, filed 2022-02

“Car makes a startling loud noise like a fog horn a few seconds after starting. Noise is loud enough and unexpected it has caused me to accidently press on accelerator on occasion if I have started moving. Apparently a know problem but fix is only European focused. Fortunately nothing was in front of me when this happened. Happens frequently on first startup but never every time. TSB is BE-00612T-TME Need to force dealers to fix this before an accident does occur.”
