GM recalling 54k Cadillac SRX, HD pickup models

There are more recalls to report General Motors, but these latest actions pertain to newer examples of the Cadillac SRX, Chevrolet Silverado HD and GMC Sierra HD. With so much scrutiny on the company's recall strategy, GM is under increasing pressure to call in defective models more quickly, and it appears to be doing so here.
Here in the US, the automaker is recalling 50,571 Cadillac SRX crossovers from the 2013 model year fitted with the 3.6-liter V6 because the transmission control module programming can cause a three- or four-second lag in acceleration at low speeds. The explanation filed with the National Highway Traffic Safety Administration states, "if the following sequence occurs within two seconds: during an upshift from first to second gear (8-10 mph), the driver then brakes the vehicle to less than 5 mph, and then accelerates again," the delay can occur. According to Automotive News, the recall effects 56,400 vehicles worldwide, and the company is not aware of any crashes caused by the problem. The fix consists of a transmission control module (TCM) reflash.
In a separate recall, GM is repairing 51 Chevrolet Silverado HD and GMC Sierra HD pickups from the 2015 model year in the US. In vehicles with diesel engines and dual fuel tanks, the nuts that connect the fuel pipe to each side of the transfer pump between the tanks may be improperly torqued, which could cause a fuel leak. Obviously, this could be a fire hazard. The remedy is simply tightening the hardware. According to GM spokesperson Alan Adler, there have been no fires actually caused by the potential leak. "Only 21 of the trucks are in customer possession and they can be fixed anytime because there are no parts involved. The others are being fixed at dealerships," Adler said in an email to Autoblog.

2021 GMC Canyon AT4 Off-Road Performance Edition is ready to hit the trail

GMC introduced a more capable Canyon AT4 named Off-Road Performance Edition that gains modifications like skid plates and a beefier suspension. It can venture further off the beaten path, but it won't get there faster. Based on the AT4, which is already better suited to venturing into the woods than the standard Canyon, the Off-Road Performance Edition gains a taller suspension and loses its sizeable front air dam to offer a 30-degree approach angle. GMC knows adventurers will be tempted to put that figure to the test, so it also added skid plates made with 5/32-inch aluminum to protect the radiator, the front differential, the steering gear, and the oil pan. Full-length rock rails on both sides shield the rocker panels from expensive encounters with boulders and other obstacles. Finally, the Off-Road Performance Edition stands out from the AT4 with specific 17-inch wheels painted in gloss black, black AT4 logos, and black exhaust tips. 31-inch Goodyear Wrangler tires come standard. Changes in the cabin are limited to floor liners. Out back, the cargo box receives a spray-in liner. Don't look for Ram 1500 TRX-like performance, because it doesn't sound like GMC made any major mechanical modifications to the Off-Road Performance Edition. Power comes from a 3.6-liter V6 that sends 308 horsepower and 275 pound-feet of torque to the four wheels via an eight-speed automatic transmission and an automatic locking rear differential provided by Eaton. AT4 buyers can order a 2.8-liter Duramax turbodiesel four-cylinder with 181 horsepower and a stout 369 pound-feet of torque on tap for an additional $4,375, but there's no word yet on whether this fuel-saving engine will be available on the Off-Road Performance Edition, too. GMC's 2021 Canyon AT4 Off-Road Performance Edition will go on sale later in 2020, though pricing information hasn't been announced yet. For context, the standard AT4 costs $39,395 in its most affordable configuration.  

GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.
