Yes. The majority of the components in the interior are plastic. Plastic can be well done though. Just compare it to a '12 Civic to see what I mean. I know. I had one. One of the worst Honda interiors ever. Acura nailed the interior of the TLX.
And as the years go on, build quality of these interiors should prove to be great as well. Only that we have to do our part and treat the leather, keep it out of the sun while exposed for extended periods of time and it will look flawless for years.
