Acura recalling nearly 20k new MDX crossovers over AWD driveshafts

Acura is recalling nearly 20,000 of its 2014 MDX crossovers fitted with all-wheel drive over driveshaft concerns. The affected vehicles were built between May 6, 2013 and October 14, 2013, and have bolts that attach the driveshaft to the transmission that may not have been tightened properly.
Needless to say, an improperly secured driveshaft could lead to a number of problems, including everything from excessive drivetrain noise to full driveshaft detachment, a condition which could result in a loss of power and crash.
There's been no reports of accidents, injuries or deaths relating to the driveshaft issues. Acura will begin notifying all 19,197 owners in question of the recall, and will request that they report in for repairs, which will consist of tightening the driveshaft-attaching bolts. Scroll down for the official bulletin from NHTSA.

A smoother operator | 2017 Acura MDX Sport Hybrid First Drive

There's a lot to unpack when trying to understand the 2017 Acura MDX Sport Hybrid. Acura is billing it as a three-row crossover infused with NSX technology via a sport-oriented hybrid drivetrain. So it's a hybrid crossover, sure. But it doesn't comport itself like a traditional crossover, nor is it a conventional hybrid. What it is, underneath, is an intentionally subtle blend of impressive technologies doing their best to appear transparent – and it's too subtle, I fear, to be appreciated by those who'd like it the most. This is a lot of foreshadowing, but if you're not familiar with the MDX Sport Hybrid's powertrain, let's fill you in. The MDX Sport Hybrid uses the same basic system as the 2014 RLX Sport Hybrid, with some newer NSX battery tech sprinkled in, packaged neatly into the refreshed third-generation MDX platform. The system improves handling and efficiency – but more important, it smoothes out the harshness of shifts and engine stop-starts. We do need to examine the system in some detail to understand how all this affects the MDX as a whole, so let's go toe to tail. Up front is a transversely-mounted 3.0-liter V6 making 257 horsepower and 218 pound-feet of torque, as well as featuring i-VTEC and cylinder deactivation. It's slightly smaller than the 3.5-liter V6 found in the conventional MDX and many other Honda and Acura products. Attached alongside is a Honda-produced 7-speed dual-clutch transmission that has a 47 hp, 109 lb-ft electric motor-generator stuffed inside. Amidships are the battery pack and the electronics to control it, and stretching aft from there are large cables feeding power to a pair of electric motors that reside in single housing, one for each wheel. Together, they produce electron witchcraft and torque-delivery wizardry – and add 72 hp and 108 lb-ft of torque to the mix. The total system output is 321 hp and 289 lb-ft of torque – a gain of 31 hp and 22 lb-ft over the conventional MDX SH-AWD. Beyond the raw numbers, there's the remarkable subjective benefit of the Sport Hybrid's drivetrain. Engine start-stop events are quiet and smooth, nearly imperceptible when under way – in stark contrast to the too-perceptible shudder of competing engines kicking on. The electric motors (mainly the one residing in the transmission) add in power to make up for the lull during a shift, making shifts up or down seamless, as well as providing regenerative capacity.

2020 Acura MDX PMC Edition coming to L.A. Auto Show

The Acura TLX PMC Edition debuted at the New York Auto Show earlier this year, the 2020 Acura MDX PMC Edition takes its turn in Los Angeles on November 20. The MDX PMC, hand-built at the Performance Manufacturing Center like the Acura NSX and TLX before it, will be limited to 330 units. The 300 examples destined for the U.S. and 30 for Canada represent 30 fewer units than the quota for the TLX PMC. That could translate into tighter demand for the MDX PMC, since the standard crossover does about 70 percent more business in the U.S. than the standard sedan. The doted-on MDX PMC follows the formula of combining Valencia Red Pearl paint with the normally-exclusive Advanced and A-Spec packages. Dark contrasts come from the body color grille surrounding gloss-black mesh, black chrome exhaust finishers, gloss-black decorating the roof, antenna, exterior mirrors, window molding, rear license plate garnish, and door handles, and gloss black 20-inch wheels. Inside is found an A-Spec steering wheel backed by metal-finished paddle shifters, black Milano leather seats with Alcantara inserts, red stitching throughout, and an individually numbered plaque identifying the build number. Extra luxury kit includes GPS-linked climate control, climate-controlled front- and second-row seats with second-row captain's chairs, and 10-speaker ELS Studio audio. The engine specs don't change, those being a 3.5-liter V6 with 290 horsepower and 267 pound-feet of torque shifting through a nine-speed automatic. Super-Handling All-Wheel Drive keeps the power in shape. When the automaker laid down a marker for the TLX PMC price, it said to expect something around $50,000, the final figure after destination coming in at $50,945. Acura says to expect the MDX PMC to figure in the "mid-$60,000 range," so don't be surprised at $66K minus some change.
