GM under fire from safety advocates over braking problem caused by recall fix

Safety experts are lambasting General Motors over what they say is the automaker’s slow notification of owners of certain 2019 sedans and trucks that a recall fix could cause power braking to fail and increase the risk of a crash, the Detroit Free Press reports.  GMÂ’s original recall in December targeted about 550,000 Cadillac CT6 sedans and Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, all from the 2019 model year, over potentially defective electronic stability control and antilock brakes. In that case, GM said the errors would not show up as a diagnostic warning on the instrument cluster. But after GM had done recall work on 162,000 vehicles, about 1,700 owner have complained that their power brakes didnÂ’t work after they had the recall done and then used the OnStar app to start their vehicle. GM then issued a supplemental fix for customers whoÂ’d already had their vehicles serviced. In this case, a diagnostic warning should illuminate saying either “Service Brake Assist” or “Service ECS,” which GM says is a signal that a customer should not drive the vehicle and instead call their dealer, which will tow the vehicle and have it repaired. Safety advocates say the automaker hasnÂ’t gone far enough to protect customers. “The fact that you could potentially start a vehicle and not have brakes is a pretty risky proposition,” Sean Kane, president of the Safety Research and Strategies, which works on auto issues for plaintiffs and governmental organizations, told the Freep. “The fact that they wouldnÂ’t notify owners (sooner) is pretty stunning.” GM told the Freep it was required to notify the National Highway Traffic Safety Administration and file paperwork before it notified customers about the original recall, which was made Dec. 12. It then had to investigate and resolve the problem created by its original recall fix before alerting customers. GMÂ’s call center and dealers are contacting the remaining 900 customers who havenÂ’t yet had the update made to the original recall repair. GM also hired a vendor to send recall letters to the 550,000 customers affected by the original recall notifying them about the update. There are no known injuries or deaths related to the problem.

Cadillac chief marketer admits ELR is 'a big disappointment'

During the Cadillac XT5 global launch in Dubai, Automobile interviewed Cadillac Chief Marketing Officer Uwe Ellinghaus and got the CMO to touch on just about every major issue affecting the brand and the industry. After two years on the job, having come from 15 years at BMW, Ellinghaus naturally started with the "passionate Cadillac customers" and "iconic brand" spiel, then they got into a top-down look at where America's preeminent luxury brand stands. Ellinghaus said Cadillac is in a period of transition, lately focused on smaller and more performance-oriented vehicles, which has alienated a chunk of veteran customers and left others trying to figure out what Cadillac is about. He believes that "for a few more years, the products will probably be stronger than the brand," while he does his work of conveying what the company has to offer. But the brand had to make the switch, because "Generation X and Y will make 80 percent of all actual buyers in the next five years..." On top of that, he'll be working on making sure the customer and dealership experiences are where they need to be. Speaking of dealers, Ellinghaus thinks the future will not be brick-and-mortar shops, but digital pickup-and-delivery services. "Nobody wants to go to a dealership for service and maintenance," he says. He said the ELR has been "a big disappointment," but it has taught Cadillac that converting its existing line-up to plug-in hybrids is a better way forward. However, he characterized the plug-in hybrid as "the next all-wheel drive," in that everyone's going to offer it soon, so it will be "an entry ticket into luxury automobiles rather than a differentiating aspect." The CMO thinks the CTS is suffering because of the decline in the US midsize luxury sedan market in general thanks to the SUV and crossover craze, so the brand really needs another small SUV. Head over to Automobile for more of Ellinghaus' intriguing answers, like "I do believe that very long-term hydrogen is really the way," and "it's time to get real" in Europe. Taking a dig at Volkswagen on that last matter, he also said, "I think the absence of the diesel is not as much of an issue as it was eight weeks ago." Related Video:

GM extending warranties on Cadillac CTS-V and Chevy Camaro ZL1 for supercharger issue

Okay General Motors, we've sat by and watched you recall the compact cars, crossovers and pickup trucks, and aside from reporting on it, we've been fairly quiet. This, though, this will not do. We can almost tolerate the recalls on the bread-and-butter cars, but leave the performance vehicles alone.
According to a report from The Car Connection, GM has discovered a problem with the superchargers of the 6.2-liter V8s found in the Chevrolet Camaro ZL1 and the Cadillac CTS-V. Apparently, the issue rests around the internal bearing shaft grease, which can become contaminated (we aren't sure with what). If left unchecked, it'll first lead to a rattle at idle, which goes away under slight throttle. The real warning stage is when a high-pitched squeal develops, signaling that the bearing shaft has failed. Naturally, severe engine damage is the next step (although it's possible that the engine will also just refuse to turnover, although neither case is desirable).
According to TCC, GM will replace the superchargers on vehicles that have exhibited symptoms of bearing shaft failure free of charge. It will also, allegedly, be extending the warranty on all supercharged ZL1s and CTS-Vs to 10 years or 120,000 miles (whichever comes first), from the date of purchase. Officially, only 2009 to 2013 CTS-Vs and 2012 to 2013 ZL1s are suffering from this issue.
