GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

GM recalls Colorado, Canyon, and Malibu for airbag problem

The Basics: General Motors will recall and issue a stop sale on 1,740 total examples of the 2016 Chevrolet Colorado, Malibu, and GMC Canyon. This includes 1,579 units in the US and 161 in Canada. The Problem: The second stage of the driver front airbag inflator might not be present. If this happens, the airbag won't fill as quickly as it should in a high-speed crash, which could increase the risk of injury, according to Reuters. This is not related in any way to Takata's inflator problems, and these parts come from a different supplier. Injuries/Deaths: None reported. The Fix: GM will replace the vehicles' airbag assemblies. If You Own One: GM spokesperson Tom Wilkinson told Autoblog he wasn't specifically sure when recall repairs would begin but said it would be "shortly." He expects the fixes to happen "quickly" because of the small number of affected vehicles, and many of them are either in transport or already in dealer stock. More Information: GM recalled the 2015 Canyon and Colorado in 2014 for a completely separate airbag issue. In that case, a manufacturing error improperly wired the connectors. Related Video: GM Statement GM is recalling 1,579 MY 2016 Chevrolet Colorado, GMC Canyon and Chevrolet Malibu vehicles in the United States and 161 in Canada to replace driver-side front airbags. The second stage of the airbag may not deploy properly in certain high-speed crashes. During a routine quality inspection, it was determined that a component required for a second-stage/high-output deployment was not loaded during the inflator build. Dealers will replace the driver-side front airbag assembly. There have been no reports of crashes or injuries related to this issue. This issue is unrelated to the ongoing Takata recalls.

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.
