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    

Will attaching the electrodes re-animate Cadillac?

This announcement last week from General Motors —"Cadillac will be GM's lead electric vehicle brand"— followed quickly by the surprise reveal Sunday night of a Cadillac EV crossover, leads one to wonder whether this is a case of GM pulling out the defibrillator and hoping a full-on jolt of electricity will revive Cadillac from its ongoing diminution in the market. In 2018, Cadillac U.S. sales were 154,702 vehicles, which was down from the 156,440 it had sold in 2017. And the 2017 sales were down significantly from the 170,006 vehicles delivered by Cadillac in 2016. And that is down from the 175,267 sales of 2015. Sure, part of Cadillac's problem — one shared by some other OEMs — is that its sedans aren't selling. But if we put those to the side, realize that in 2018 sales of the venerable Escalade were down by 2.2 percent. Admittedly, that rig is a little old in the grille, and it's suddenly gotten strong competition from the Lincoln Navigator, so a sales decline isn't too surprising. But the XT5, the compact lux vehicle that was launched in 2016 as a model-year 2017 product, had an 11.3 percent decline in a segment that is doing nothing but growing. This is not promising. Although the argument at GM HQ might be that Cadillac can reinvent itself as a Tesla fighter, one of the things that isn't often noted about Tesla vis-a-vis other OEMs is that while sedan sales are generally down, Tesla, which had an estimated 2018 sales volume of 197,680 (according to Cleantechnica.com), made its numbers primarily with the Model 3 and Model S, both sedans, as it has just the Model X crossover. So it isn't just about vehicle architecture. It is going to take more than an electric SUV to change Cadillac's performance. But here's where circumstances can fall in Cadillac's favor. Scale can be highly beneficial to Cadillac versus Tesla. The Chinese market, even though it is weakening of late, will be largely predicated on "New Energy Vehicles," which means electrified and fully electric. And while Tesla only just now broke ground on a factory in China, LMC Automotive reports that as of December 2018, SAIC GM is already well-established there and is the third-largest vehicle manufacturer in China (behind SAIC Volkswagen and FAW Volkswagen). Cadillac is going to be able to take advantage of GM's global efforts in developing EVs, so soon the Cadillac showroom could be filled with an array of luxury EVs that may make even Tesla loyalists take another look.

2020 Cadillac CT4 revealed in non-V form

We got our first look at the 2020 Cadillac CT4 when its V variant made its debut a few months ago. Now the company is officially showing off the regular CT4 luxury sport sedans. They actually don't look all that different from the V, though - especially the CT4 Sport trim. The Luxury and Premium Luxury trims are distinguished by less aggressive ground effects and a grille studded with chrome pieces shaped like the Cadillac logo. The interior is similar, too, complete with an 8-inch touchscreen. Super Cruise will be made available on the CT4 later in 2020, including on the V model. Really, the big news is the powertrain as V6 engines have been dropped entirely from Cadillac's compact sedan. The base CT4 engine available in Sport or Luxury trim cars is a turbocharged 2.0-liter four-cylinder making 237 horsepower and 258 pound-feet of torque. Coupled to either rear- or all-wheel drive, it features cylinder deactivation and an eight-speed automatic transmission. Unlike in the old ATS, a manual transmission is not available. One notable mechanical difference between trims is the Sport trim gets standard Brembo brakes. Moving up from the 2.0-liter engine is the turbocharged 2.7-liter four-cylinder introduced on the CT4-V. Available on the Premium Luxury trims, its output is downgraded to 309 hp and 348 lb-ft of torque from the CT4-V's output of 325 hp and 380 lb-ft. It too has cylinder deactivation and can be had with either rear- or all-wheel drive. The only transmission offered is a 10-speed automatic. The V model also gets Brembo brake upgrades, and with rear-wheel drive includes Cadillac's magnetically controlled adaptive suspension. Cadillac will start taking orders for the CT4 later this year, but pricing has not been announced yet.
