2021 Acura TLX A-Spec Long-Term Update | Infotainment system hits a pothole

The first few thousand miles of motoring in our 2021 Acura TLX A-Spec long-term test car were problem-free, but that changed after we took it on a spirited drive through the winding hills of southern Indiana. You can read about how it handled a full day of thrashing here, but this story will focus on the dead infotainment system previewed in the headline. About halfway through the twisty route, every sizable pothole or big bump in the road would cause the infotainment system to black out. A message would appear declaring “MOST NET LOSS,” and it would quickly dip to black after that. The next big pothole would cause it to flicker back on, but it never remained on for any long periods of time after this. In addition to the screen loss, the speakers would make some rather disturbing crackling noises. This continued throughout the day and for several days beyond that. If the roads I was driving on were flat or devoid of major problems, the infotainment system would generally be fine. It took a major jostling of the carÂ’s bones to cause it to act up, but Michigan provided enough of those to make the problem exceedingly annoying in a hurry. So, to the dealership it went. 2021 Acura TLX A-Spec View 51 Photos After the local dealer looked it over, they said there was a TSB out for this issue, and that theyÂ’ve seen it pop up on other RDXs and TLXs already. Turns out, there are a number of wire connectors between the infotainment system and wiring harness that are causing the problems and coming loose. The fix? Newly designed connectors from Acura, plus the wiring harness is ever so slightly freed up to allow for a bit of movement from violent impacts. Doing this (plus using the stronger new connectors) should ensure that the stress on these connectors is never so great as to cause issues again.  The job was completed under warranty and took a full day from diagnosis to the return of the car. WeÂ’ve put several hundred miles on the car since the fix, and theyÂ’ve been completely trouble-free — it sure was nice to listen to AcuraÂ’s excellent ELS audio system again. That said, this issue is one weÂ’ll follow closely to see if AcuraÂ’s fix truly is a long-term solution. WeÂ’ll have a deeper dive on how AcuraÂ’s TouchPad infotainment system works (now that itÂ’s actually working again) soon, so watch out for that update in the near future.

Acura NSX bodywork to be sheathed in zirconium e-coat, fewer paint layers

Automakers make halo cars to drum up excitement and show off what they can do, but there's more to it than that. Advanced platforms allow a company's engineers to experiment with all sorts of technologies. And in the case of the upcoming new Acura NSX, that includes new paint processes.
Speaking with Autoline in this video interview, Honda's North American Senior VP Jon Minto talked about an innovative zirconium e-coat which it's applying to the new NSX. Unlike some experimental paints developed for Formula One, however, this coating is not designed to minimize drag or enhance cooling: it's designed to be more environmentally friendly.
It's one of a few measures which Honda is implementing on the NSX before expanding it to more accessible models, along with another process that uses fewer coats to reduce energy consumption by 40 percent. Watch the interview with Autoline host John McElroy right here.

Acura NSX owners receive custom short teaser movies of their personal car

In a neat bit of fan service for those who've ordered Acura's new NSX halo car, the company will make a short film that reflects the way the car's been configured. Those films are on their way to future owners as you read this. In addition, they'll get a 1:18 scale custom model of their own car, reflecting every appearance option inside and out. That's neat. So neat, in fact, that we decided to commission our own video. We got together and configured a car in the lovely Nouvelle Blue Pearl, and sent our build over to Acura. They put together a video that's mostly representative of what an owner would see. You can see our build plate (hint: it says "Autoblog – Precision Crafted By Performance Manufacturing Center" on it), and that's "our" car on the dyno starting about 22 seconds in. If you want to check out someone else's film, you can compare our build to Jay Leno's. The reason Acura can do this is that there simply aren't that many available configurations for the NSX. This is at the root of one of the main criticisms some of our editors have about the car. An NSX starts at darn close to $160,000, and there are eight paint options (not too bad), four interior color options, and three seating options. All well and good, but compare that to the 16 paint and 12 interior color/material choices in a 911 Turbo, for example, choosing a similarly high-performance car at a similar price range. And there's a further wrinkle: Porsche will paint your car to match a sample you provide, so in reality the ability for an owner to make the car uniquely theirs is infinite, if you don't mind paying for it. See also the BMW Individual program, or McLaren's MSO one-offs. We're not just talking about the MSO Defined options, but the MSO Bespoke program itself, which will basically do anything you want to the car as long as it's road legal and your check doesn't bounce. We've been to MSO, and they're not kidding: they'll build anything. So yes, these custom videos are nice fan service, and they'll certainly jazz up the buyers who've already ordered one of these dynamically impressive cars. It's a move that builds loyalty, and certainly doesn't have much of a drawback. But for us, already a bit sensitive to Acura's conservative option list for the NSX, it serves to highlight the gap between Acura and the more established brands in catering to well-off customers' desire for bespoke range-topping creations.
