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 to climb Pikes Peak with Integra Type S and wildly modified NSX

This year marks the 101st anniversary of the Pikes Peak International Hill Climb, one of the oldest motorsports events in the world. As has been the custom for the past 13 years, Acura will head to the Colorado summit with a fleet of specially prepped cars based on production models. This year, their team consists of two new Integras in regular and Type S flavor, a modified NSX Type S, and a TLX Type S pace car. Of the Integras, the HPD-prepped Type S will be the most eye-catching, as it's wrapped in an anime-style livery. It's an extension of the company's "Chiaki's Journey" web series whose second chapter was released to coincide with the Integra Type S's launch. The second installment features the Pikes Peak race as part of its story line.  The real-world Chiaki is Lori Unser, a fourth-generation driver in the Unser racing dynasty. Her father Johnny raced at the Indianapolis 500, and if you count her extended family of Al, Bobby, and Al Jr., the clan has nine Indy championships under its collective belt. The family also has a history of racing at Pikes Peak, with Louis and Joe Unser competing in the hillclimb way back in 1926. In the Time Attack I division Acura is fielding a wild-looking NSX Type S called the Active Aero Study. We prefer its nickname, Yamabiko, which means "echo" in Japanese but is also the name of a spirit from Japanese folklore that lives in the mountains.  The NSX wears an enormous carbon fiber front splitter and rear diffuser, which by the looks of them extend the length of the car by two to three feet. The one-off aero bits include an active aero rear wing that can be electronically moved to reduce drag on high-speed sections of the course, or deployed as an air brake. At the same time, enough has been stripped out to reduce weight by 200 pounds. More powerful turbos have been fitted to the twin-turbo V6 and the engine software re-written, but Acura did not reveal how much over the stock Type S's 600 horsepower Yamabiko's output might be. The NSX was built specifically to tackle the hillclimb by Crazy New, the skunkworks team of Honda employees that brought us the 800-horsepower CR-V Hybrid. It'll be driven by Honda engineer James Robinson, who holds the current Hybrid class record of 10:01.913, which he set with an NSX in 2020. With Yokohama Tires' trademark Advan black and red livery and lightweight HRE forged wheels wrapped in Advan A005s, it certainly looks the part of a purpose-built Pikes Peak racer.

MotorWeek remembers retro icons, Supra and NSX

It's easy to poke a joke here and there about John Davis, the long-time host of MotorWeek. His voice is so monotonous that, from time to time, if you closed your eyes, you may think it's generated via a computer. But you have to give him and the rest of the show a lot of credit. The program has been on the air for decades, giving people direct, straight-down-the middle automotive reviews.
MotorWeek's massive back catalog of reviews are slowly making their way onto YouTube, and they provide a fascinating chance to look back on how performance cars rank against their contemporaries from back in the day. Two recent additions include the show's old looks at the 1986 Toyota Supra, the dawn of the third-generation model, and the now-iconic 1991 Acura NSX.
Both reviews are interesting in their own way. These days you hear nary a negative word about the original NSX, but MotorWeek isn't afraid to point out a few flaws. And the Supra really shows the progress of suspension tuning in the intervening decades because it has some serious body roll in the corners.
