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 vs. luxury sedans: How they compare on paper

The 2021 Acura TLX has been revealed, and it looks superb. We also have a handful of hard numbers, so you know that we've got to take a look at how they compare to the competition. As we only have numbers for the base turbocharged four-cylinder model, we're only looking at similarly equipped competitors. And with the small to midsize luxury sedan segment burgeoning these days, we've selected a mix of rear-drive, front-drive and all-wheel-drive options to compare to this front-drive-based sedan. You can see the raw numbers below, and a summary of them under that. Engine and transmission The Acura's base engine is a turbocharged 2.0-liter four-cylinder, just like the vast majority of cars in its segment. It's an especially powerful base engine, though, with 272 horses. That tops every base engine in this group, and is only topped by Volvo's mid-range turbocharged and supercharged four-cylinder that makes 316 horsepower. Its torque rating is strong, too, falling short of the aforementioned Volvo engine and the BMW four-cylinder. You'll note that we've included two four-cylinder engines for the Audi and the Volvo. With the Audi, the entry-level engine is seriously underpowered versus the competition, whereas the higher-output version is more comparable, so we felt it should be included. As for the Volvo, since the turbo and supercharged engine isn't quite comparable to each of these model's six-cylinder alternatives, we felt it should be mentioned, here. Many of these cars have substantially more powerful alternatives available, including the Acura. The Acura will have a twin-turbo 3.0-liter V6, but we have no specifications for it. It will face off with the 382-horsepower BMW M340i, 400-horsepower Volvo S60 T8 hybrid, 365-horsepower Genesis G70 3.3T and 349-horsepower Audi S4, among others. The Acura is available with either front-wheel drive or all-wheel drive, and every version gets a 10-speed automatic, giving it claim to the most gears. All the other cars here make do with an eight-speed automatic. The Genesis G70 is the sole offering with a manual transmission, something that's offered on the Sport trim with upgraded brakes and a limited-slip differential. The Audi is unique in making all-wheel drive standard. On the Volvo, all-wheel-drive is only available if you upgrade to the higher-output engine, another reason why we wanted to include it. Size On the outside, the Acura is the largest, or more specifically, the longest.

Acura puts on display of mechanical horsepower in new ad

Originally forged with a brand identity based on luxury, sportiness and practicality, Acura has spent the last decade or so struggling with its image. The sporting credibility suffered a mighty blow with the loss of cars like the Integra, RSX and NSX, and recent years have seen the Japanese company attempting to recast itself as a technology leader.
All of that makes this latest Acura commercial, Let The Race Begin, even more difficult to understand, metaphorically speaking. The horsepower-horse race 'theme' certainly isn't difficult to fathom, with mecca-equine versions of popular luxury brands filling the screen. But the choice to make Acura's filly a flesh-and-blood creation seems odd, for the high-tech theme. Acura as "thoroughbred apart from the rest of the field" seems to be the rough message here, though we're not sure we're buying it. We're also not sure we're comfortable with how much these ponies reminded us of a certain off-putting robotic dog...
Looks expensive, at any rate. Watch the robot ponies run for yourself, below.
