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 GT3 data 'will inform future iterations' of the street car

Motorsports programs exist to drive innovation in road vehicles, and that's precisely what's happening at Honda. Acura NSX development boss Nick Robinson told Autocar that the company's work on the GT3 racing variant is directly informing future development on the road car. "In North America, we've just unveiled the GT3 version of the car, and the development team of the street car has had some involvement in its development," Robinson said. "What works well on the track will inform future iterations and updates of the street car and vice versa." But Honda is a big company that does more than build cars. Robinson paid tribute to the impact his employer's well-known motorcycle program had on the NSX. Apparently, building stuff like the CBR helped Honda with the NSX's complicated packaging. "For many years our motorcycle development teams have strived to ensure the optimum centralization of mass, ensuring the lowest possible center of gravity," Robinson told Autocar. "This leads to the best possible yaw response." Is this all a sign that a long-rumored lighter, faster NSX, potentially wearing the vaunted Type R badge, will be especially track-focused? Maybe. Robinson's comments indicate that the company is doing something with the mountains of data it collects running a GT3 program. While a pure road-focused NSX-R successor seems like it'd be a waste of that data, an NSX-based rival to the Porsche 911 GT3 RS might make a lot more sense.

2019 Acura RDX First Drive Review | Boringness banished

WHISTLER, B.C. — Things have come full circle for the Acura RDX. The compact crossover launched in 2007 with an all-new turbocharged four-cylinder engine and an all-wheel-drive system that was sophisticated enough for the brand to affix the Super Handling designation to it. It was a fun, sporty vehicle in a sea of boring competitors, and we liked it enough to write a eulogy of sorts when the second-generation RDX ditched the fun turbo engine in favor of a V6, and dumbed down its optional all-wheel system so much that they dropped the Super Handling name. Acura's mainstreaming of the RDX for its second generation turned out to be a smart play. Sales jumped 94 percent in 2012, the first year that the redesigned RDX went on sale, leapt another 50 percent the following year, and have stayed over the 50,000 mark for the past three years. It may sound surprising, then, that Acura is flipping the playbook back a few pages by swapping its V6 engine back to a turbo four and reinstalling Super Handling All-Wheel Drive. We think it's a smart move. The 2019 RDX is both sportier and more upscale than the model it replaces. It does more than just check boxes. It's interesting, boasts some cool technology, and offers a strong value proposition. The 2019 RDX's all-new 2.0-liter turbocharged four-cylinder engine delivers 272 horsepower and 280 pound-feet of torque. That's down a negligible seven ponies from the old 3.5-liter V6, but up 28 lb-ft, and it's tuned to provide the bulk of that torque in the heart of its powerband — peak torque plateaus between 1,600 and 4,500 rpm. An equally all-new 10-speed automatic transmission sends that power to either the front wheels, or, as was the case with the vehicles we tested, all four wheels. Jumping into a 2019 RDX for the first time, our main powertrain concern was that the 10-speed automatic would generate a ton of unnecessary, and distracting, shifts. This proved to be an unfounded fear. The gearbox does shift quite often under hard acceleration, but does so quickly and without any undue jerkiness. The sheer number of gearing options — the old six-speed auto had a 68 percent narrower spread of ratios — and the torque-rich engine combined to provide excellent straight-line acceleration in any real-world driving scenario we could conjure. The rest of the time we didn't really think about the transmission at all. We did, however, lament the push-button transmission interface.
