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.

Snapshots from Acura NSX prototype run at Mid-Ohio

Acura's achingly slow showing of the new, hybrid NSX saw yet another step yesterday, as we reported late last week. A powder-blue prototype ran ahead of the open-wheelers at the Honda Indy 200 at the Mid-Ohio Sports Car Course. Why show the NSX Prototype at Mid-Ohio? Honda's Ohio research and development center, which has taken the lead on NSX development, is just 60 miles from the track. And as race sponsor, Honda must have figured it would give the spectators a glimpse of the new supercar it's been teasing for the better part of a decade.
With a planned launch in 2015 (special emphasis on the "planned" part, considering the NSX's history), the NSX Prototype shown here sports graphics that "speak to Acura's intention to go racing with the new NSX." That's great news for fans of endurance racing, although it remains to be seen when a motorsports program for the new NSX will get off the ground.
Take a look at the fresh gallery of images, and be sure to head over to our original Mid-Ohio post for the video footage of the NSX Prototype on track.

Production Acura NSX spied getting sharper on the 'Ring

Acura hasn't been shy about trotting out the concept version of its upcoming NSX hybrid supercar - we've seen it colorized on Facebook, wearing Super GT drag and running wrapped at Mid Ohio - but until now, we've missed seeing the production version at all. Thankfully, our boys in the field have been diligently camped out by the Nürburgring, just the place for Acura engineers to get the NSX shaken down and ready for the public.
The first thing you'll likely notice (and no doubt appreciate) is that Acura is staying very true to the concept car. The same wind-tunnel-carved wedge shape is in evidence in the car's silhouette, and details like aggressively scalloped engine vents behind the cabin have made it through unscathed.
We do notice that there are some vertical elements at the bottom of the front fascia/grille that appear to be revised, and the mirrors are considerably less slinky than those of the concept car. Still, by and large, we're seeing a direct translation from show stand to real life here.
