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.

2021 Acura TLX Long-Term Update | Pleasurable drive, puzzling gremlin

This was my first long haul behind the wheel of our long-term 2021 Acura TLX, and past experience with the brand (and Honda in general) led me to believe that if I could get past any seat comfort issues, the TLX and I would get along just fine. As it turned out, I had no cause to worry in the first place. The TLX’s seats are comfortable and supportive enough for my typical driving position – and look great in red to boot. Not having to worry about my back screaming at me after a couple solid hours on the highway, I was able to devote my attention elsewhere, and the report is largely positive. To me, the most impressive thing about the TLX is how small it feels from behind the wheel. IÂ’ve had it in my driveway for nearly two months (for various reasons, none of them good; look for more in a future update) and despite driving it rather frequently, I often forget that itÂ’s a midsize. HowÂ’d Acura accomplish that? ItÂ’s all in the feedback. The steering is dialed in pretty much perfectly and lacks the artificial and distant sensation present in AudiÂ’s FWD-based luxury sedans, for example. IÂ’d even put the TLX ahead of BMWÂ’s 2 Series Gran Coupe in this department. Sure, theyÂ’re very different vehicles, but that Acura can accomplish this with something as large as the TLX while even BMWÂ’s compacts disappoint? Well, it says something. And though it may feel small, it isnÂ’t. The TLX more than accommodated enough luggage for two people traveling to a Lake Michigan wedding over a long weekend, and did shuttle duty throughout the festivities without even a peep from rear-seat passengers, apart from commentary about the red leather. ItÂ’s a bit polarizing, IÂ’ll admit, but I think it looks great against the blue exterior. 2021 Acura TLX A-Spec View 51 Photos Over the 500-mile round trip, the TLX averaged just a hair under 30 mpg (against an EPA rating of 29 mpg highway; score one for the numbers geeks) at cruising speeds of 75-80. Michigan highways arenÂ’t known for top-notch surfaces, but even on the grooved pavement found on many of its interstates and other rural expressways, tire hum never became intrusive. Present? Sure, just not unpleasantly so. My gripes are few. I wish the cruise control would be a bit more aggressive in accelerating to a set speed when resumed, for one; it seems downright lazy under certain conditions. I could also do entirely without the silly touchpad-like infotainment interface.

Inside Honda's ghost town for testing autonomous cars

On the edge of the San Francisco suburb of Concord, California sits a ghost town. Dilapidated buildings and cracked roads are framed by overgrowth and slightly askew street signs. The decommissioned five acre portion of the Concord Naval Weapons Station that once housed military personnel and their families is now home to squirrels, jack rabbits, wild turkeys and Honda's mysterious testing lab for autonomous vehicles. This former town within a Naval base – now dubbed "GoMentum Station" – is the perfect testing ground for Honda's self-driving cars. An almost turn-key solution to the problem of finding somewhere to experiment with autonomous vehicle inside an urban area. Thanks to the GoMentum Station, the automaker has access to 20 miles of various road types, intersections and infrastructure exactly like those found in the real world. Just, you know, without all the people getting in the way. While the faded lane markers and cracked asphalt might initially make it difficult for the car to figure out what's going on around it, that's exactly what you want when training a self-driving system. Many roads in the real world are also in dire need of upkeep. Just because autonomous vehicles are hitting the streets doesn't mean the funding needed to fix all the potholes and faded lane markers will magically appear. The real world doesn't work that way and the robot cars that will eventually make our commutes less of a headache will need to be aware of that. Plus, it's tougher to train a car to drive downtown than to barrel down the highway at 80 miles per hour. A company is going to want to get as much practice as possible. While semi-autonomous driving on the everyone-going-the-same-way-at-a-constant-speed freeway is already a reality, navigating in an urban environment is far more complex. If you've driven on the streets of Los Angeles, San Francisco, New York, Chicago or Seattle you know that driving downtown takes far more concentration than cruising down the interstate. With all that in mind, Honda's tricked out Acura RLX did a good job during an (admittedly very controlled) hands-free demo. It didn't hit either of the pedestrians walking across its path. It stopped at stop signs and even maneuvered around a mannequin situated in the middle of the road. The reality is, watching a car drive around the block and safely avoid stuff is boring. Not to metion, Google has been doing this for a while in the real world.
