GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video    

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.

Cadillac clears camo off the XT3 revealing grille, lighting details

Up until now, every Cadillac XT3 we've seen has been buried under covers and vinyl wraps, but one of our spy photographers recently captured a group of them with significantly less camouflage. As a result, we finally get a relatively clear picture of what the car will look like. The nose blends the look of current Cadillacs with cues from last year's Escala concept. The headlights still appear to stretch up into the top of the fenders like its production brethren, but they don't descend as far down the front fascia, a hint of Escala influence. The grille also features more of egg-crate mesh like that Cadillac concept. In profile, we can see evidence of the XT3's smaller size compared with the XT5, mainly in the lack of any glass area behind the rear door. Other evidence of the smaller size is that our spy photographer reports the cars were being tested alongside the BMW X3 and Mercedes-Benz GLC-Class. The profile also shows that the XT3 will have a hard-edged rear end with a rakish hatch. At the back, there isn't a whole lot to report, but the taillights look like they'll be interesting. There appears to be a horizontal element in the middle of the hatch similar to what we've seen on the Escala and the refreshed XTS. We can also see some lights up on the C-pillar, which indicates that the XT3 will also have tall vertical elements up those pillars like on the Escalade. We expect the XT3 to show up late in 2018. It will likely be powered by a turbocharged four-cylinder of some sort, and because it will probably be based on an existing GM crossover or sedan platform, it will probably have front-wheel drive and/or a front-drive based all-wheel-drive system.
