GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

GM recalls 51k Enclave, Traverse, Acadia crossovers over fuel gauge inaccuracy

With all eyes fixed on General Motors in the wake of the ignition recall debacle, the auto giant has been carefully calling in a wide array of vehicles to fix anything and everything that could prove problematic. Just the other day it issued two separate recalls - one concerning the Cadillac SRX and another its heavy-duty pickups - and now it is issuing another.
This time the vehicles in question are the Buick Enclave, Chevy Traverse and GMC Acadia, three fullsize crossovers based on GM's Lambda platform. In an estimated 51,640 units manufactured between March 26 and August 15, 2013, the engine control module has been found to incorrectly display the level of fuel in the tank.
As a result, owners are being notified to bring their vehicles in to their local dealers to have the ECU reflashed to fix the problem. View the full details in the announcement below from the National Highway Traffic Safety Administration.

2019 Buick Regal GS Review | Because Buicks are allowed to be cool, too

Buick continues to try to convince everyone that its cars are cool, but we still haven't seen much evidence of this working. However, the 2019 Buick Regal GS is exactly the car that can help change people's minds about Buick in 2019. It has big red Brembos sitting inside superbly stylish wheels, bright red GS emblems everywhere, aggressive bodywork and some of the best sport seats in any car today. Buick truly made the GS look the part, and if you can get past the brand's Wal-Mart greeter personality, you're going to like the way it drives, too. The Regal GS is powered by GM's 3.6-liter V6 that makes a healthy 310 horsepower and 282 pound-feet of torque in this application. That gets mated to a nine-speed automatic transmission, which is the only option for the GS this time around. The previous generation Regal GS offered a six-speed manual, but we weren't missing it too badly here. With seemingly every car under the sun going the turbocharged route, it was refreshing to see GM use a big, naturally aspirated V6. Even stranger was that the Regal GS before this one was boosted, so you could say GM went the opposite direction of the industry trend. That previous GS made 270 horsepower and 295 pound-feet of torque from its turbocharged 2.0-liter four cylinder. So, while the V6 beats it by 40 horsepower, the old GS has it by 13 measly pound-feet of torque. Still, we dig the V6, because this car's power delivery is fantastic with a snarly but restrained exhaust note to go with. My largest quibble is taking off from a stop. The GS's throttle response is a little numb from the get-go, but put any revs to it and the car is ready to leap forward at any speed. This immediacy is increased when you put it into "GS" mode, which sharpens up the throttle, quickens shifts, stiffens the suspension, sends more power to the rear wheels and makes the steering heavier. The nine-speed is seamless and unobtrusive in traffic, but offers up surprisingly quick shifts when you're flat-out. Most of the time I end up ignoring the paddle shifters on cars with torque converter automatics, so I wasn't exactly missing them here. You can select the gears via the gear lever's slapstick function if you really want to, but it's hardly more engaging than just letting the car go at it. In GS mode it holds gears long enough and resists shifting out of the power band. During fall-attack on a backroad, it works smart and is on-par with the eight-speed in our Stinger GT long-termer.
