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.

GM admits Cadillac ELR no real competition for Tesla Model S

Last year, then-CEO of General Motors, Dan Akerson, made it clear that the company lookouts at the Ren Cen had California automaker Tesla in their sights. "If you want to compete head-to-head with Tesla, and we ultimately will, you want to do it with a Cadillac," he said. So, given the fact that the Cadillac ELR has a plug and sells for roughly the same price at the Tesla Model S ($75,000 vs $69,900, before incentives) and that Cadillac doesn't have any other electric vehicle on the horizon, you'd be forgiven if you thought that the way that Akerson wanted to challenge Tesla's EV success was with the ELR. Well, you'd apparently be wrong. "The ELR is a different car, it's a different price point. It's way-different technology." - GM's Mark Reuss Speaking yesterday in Detroit, GM's head of global product development, Mark Reuss, admitted that the ELR is not the Tesla competitor that Akerson promised. "People like to say the ELR is [competition for the Model S], but it's really not. It's a different car, it's a different price point. It's way-different technology." So, if we follow that logic to conclusion with Akerson's quote from last year, then the only way that Cadillac can eventually compete with Tesla is with a pure electric car, and that seems an outside chance, at best, for the foreseeable future. Through the end of July, Cadillac has sold 578 ELRs since it went on sale earlier this year. Tesla doesn't break out monthly US sales, but has sold 15,114 Model S EVs around the world in the first six months of 2014. For his part, Tesla CEO Elon Musk has already said that GM is headed down the wrong path with plug-in hybrids like the ELR or the Chevy Volt. Speaking about the Volt last year, Musk said, Chevy "sort of created something that's a bit of amphibian," which resulted in a car that's, "Okay but not great."

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.
