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.

Both Android Auto and Apple CarPlay slated for Chevrolet lineup

Long awaited, the race among automakers to keep drivers connected to their smartphones has officially entered a new era. Hyundai said Tuesday it would be the first manufacturer to put Google's Android Auto into a production car, the 2015 Hyundai Sonata sedan. Not to be outdone, General Motors said today it'd offer both Android Auto and Apple's CarPlay on several Chevrolet models set to hit dealerships this summer. By giving car buyers the choice between these rival phone-projection systems, Chevrolet hopes to quell concerns from prospective customers worried about the compatibility of their smartphones and vehicles. "It's about providing choice," said Alicia Boler-Davis, GM's senior vice president for global connected car consumer experience. "No two customers are alike, and we cannot expect a single solution that works for every driver in every situation." Across the industry, automakers are rushing to add both to their cars as a growing base of customers seek an array of connected features. Estimates from automotive technology research firm SBD indicate smartphone-integrated content is available in 36 percent of current vehicles, and the company expects that penetration rate will grow to 84 percent by 2025. For Chevrolet, the systems will be available on select 2016 iterations of the Cruze, Camaro, Volt, Spark and Malibu as early as next month, and appear on 14 Chevy models overall for the 2016 model year. They're available on all trim levels, but they only work with the company's MyLink infotainment package installed in the cars, and the first to hit showrooms will only work on the seven-inch touchscreen models. "CarPlay and Android Auto, these are things that are addressable to the broad market, and I think it makes a lot of sense for GM to put it into Chevys first," IHS Automotive senior analyst Mark Boyadjis said. Via physical connections, both Apple CarPlay and Android Auto allow users access to smartphone features like turn-by-turn directions, phone calls, voice-to-text messages and music streaming. Interfaces are similar to the ones found on the respective smartphones, but on the dashboard, they're redesigned for a simpler, in-car experience. Fonts are larger, for example, and easier to press on a touchscreen. CarPlay relies heavily on Siri so that drivers spend more time staring at the road instead of their touchscreen. That sounds good, at least in theory.

2021 BMW M3 and M4 vs all the high-powered sport sedans and coupes

Should you have a found a way to get past that schnoz, you've probably digested some of the basic specs for the all-new 2021 BMW M3 sedan and M4 coupe specs. They're plenty impressive. There's also, basically, two sets of them thanks to the regular and Competition versions that differ in engine output and transmission type.  But how do they compare to other ultra sport sedans and coupes? Well, we were wondering that too, so we fired up the Autoblog Comparison Spreadsheet Generator 5000 (aka me chained to my computer in a dark basement).  Sadly, there are surprisingly few competitors for the 2021 BMW M3. Rival sedans include the Mercedes-AMG C 63 and the Alfa Romeo Giulia Quadrifoglio, along with the Audi RS 5 Sportback sedan/coupe/hatchback thing. There's no more Lexus IS F, the Cadillac CT4 Blackwing has yet to arrive and Jaguar doesn't offer a spicy XE R.  Happily, there are more coupe rivals for the 2021 BMW M4, including the two-door versions of the AMG and Audi as well as the Lexus RC F. I also included the Ford Shelby GT350 and Chevrolet Camaro SS 1LE. On paper, they align incredibly well. On the street and on a track, I can personally attest that these Americans are fully capable of keeping up and/or bettering the fancy-pants luxury brands (and let's not forget there are even more powerful, hardcore versions available). If they don't align in terms of price or prestige, whatever. OK, let's get to the spreadsheet. Let's start with the coupes and note that I didn't bother listing the dimensions for the M4 Competition and C 63 S as they are identical to their "lesser" siblings.  I won't bother burning words explaining what you can see on the chart. Instead, I'll point out a few things that stood out to me. First, BMW M comes awfully close to matching the output of AMG's twin-turbo V8 despite having two fewer cylinders. Similarly, Audi manages to better the 0-60 time of the M4 Competition and tie the C 63 S despite being WAY down on power. It's not like it weighs less. Magic? Second, and speaking of 0-60 times, remember the importance that transmission and drivetrain make with them. It's not just horsepower and torque. An automatic will be quicker and easier to launch than a manual, while all-wheel drive provides more instantaneous and beneficial grip.
