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 TLX GT Racecar bringing the 'X factor' to Pirelli World Challenge

One doesn't normally think of Acura offering anything to mix it up with the SRT Viper, Lamborghini Gallardo, Mercedes-Benz SLS AMG, Nissan GT-R, Audi R8 and Ferrari 458 Italia (at least while the NSX is still off in the ether), but that's exactly what's about to happen. Honda's premium outpost is jumping into the top tier of the Pirelli World Challenge with this 2015 TLX GT.
The surprise reveal of this racecar at today's Detroit Auto Show will be campaigned by RealTime Racing, no stranger to racing Acuras, in the GT class (previously, the team had campaigned the series a rung down in GT-S).
The racecar is powered by a twin-turbo variant of the direct-injected V6 to be found in the production TLX sedan, right along with its Super-Handling All-Wheel Drive system. There's no word on how much power this HPD-massaged engine will put out in race trim, but we won't have to wait long to hear it fire up - the car is set to take to the track with team owner Peter Cunningham at the wheel in the next few weeks.

2017 Acura NSX | 2017 Autoblog Technology of the Year Finalist

Like its iconic predecessor, the second-generation Acura NSX blazes trails. The old NSX proved that you could get reliability and daily use from an exotic car, and subsequently changed the automotive world. Acura's engineers pushed in a new direction for the prodigal successor: technology. And so the new NSX sets a new bar in the way technology is used to achieve speed. The highlight here is the Sport Hybrid SH-AWD system, which supplements the 500-horsepower twin-turbo V6 with three electric motors, making 573 peak ponies. The two front motors each act on a front wheel, doing all kinds of tricks to help the car corner faster, brake harder, and accelerate like the proverbial cannon shot. They help make the NSX more stable at high speed, and let you sneak up on unsuspecting video producers at low speed. Then there's the third motor sandwiched between the engine and nine-speed transmission, which never lets a shift go by without filling in the milliseconds with velvety torque. If the all-wheel-drive hybrid supercar sounds familiar, yes, Porsche did something similar with the 918 Spyder. But even when you load the options on the NSX (try not to, we dare you), it's never more than a fifth the price of the Porsche. Then there are the little details, like a new form of casting Honda engineers developed for the NSX's crash structure. Or the three-dimensional bend to the A-pillar and roof rail that makes it less obstructive to the driver and also stronger. Even the Marysville, Ohio factory gets some credit here, with 12 patents filed relating to the assembly process. There's only so much a driver can do with two hands and two feet. The NSX takes your inputs and figures out how to maximize the contribution from each individual wheel. This is a car that harnesses all the greatness of technology to change what's possible in a sports car.Related Video: 2017 Acura NSX | First Drive
