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.

Chevy will reveal the Bolt EV tomorrow at CES

The moment that electric vehicle consumers and green propulsion enthusiasts have been waiting for is almost upon us, as Chevy confirmed that it will unveil the production version of the 2017 Bolt EV Wednesday at CES in Las Vegas. Chevrolet previewed the Bolt in concept form at the Detroit Auto Show almost a year ago, proposing a compelling rival to the likes of the Nissan Leaf and BMW i3. We've expected the CES debut for awhile, and Chevy projects that the finished product will boast a range of more than 200 miles on a single charge. That's nearly double the Leaf's range, and significantly farther than the i3 will travel even with the Range Extender kicking in. All of that for under $30,000 after federal tax credits. Of course, Chevy's own Spark EV costs much less, but will only go 82 miles before it needs to plug in again. If you won't be in Vegas for the unveiling tomorrow, you can catch it on Facebook. It will be the first vehicle to debut on the new Facebook Live, featuring both a live video stream and a 360-degree interactive interior video. Once out on the market, the Bolt EV will join the Spark EV, Volt PHEV, and Malibu hybrid in a growing array of electrified vehicles from the American automaker, rivaling the likes of Toyota and Nissan for the most electrified vehicles in its lineup. Chevrolet Bolt EV Will Debut at CES 2016-01-05 DETROIT – Chevrolet will unveil the 2017 Bolt EV at the International Consumer Electronics Show (CES) in Las Vegas on Wednesday, Jan. 6, and be the first auto brand to work with Facebook to debut a vehicle using Facebook Live. With the addition of the Bolt EV to a lineup that includes the all-new 2016 Volt, 2016 Malibu Hybrid and Spark EV, Chevrolet will offer consumers more affordable, electrified vehicle options than any other major automotive brand – solidifying its position as the leader in electrification. "The Bolt EV truly embodies the ingenuity that is at the core of everything we do at Chevrolet," said Alan Batey, president of General Motors North America and head of Global Chevrolet. "The technologies and the engineering expertise behind the Bolt EV are tremendous examples of the kind of innovation we intend to offer our customers, across an array of products at a tremendous value – something only Chevrolet can deliver." Building on the electrification expertise established by the Volt, the Bolt EV is a game-changing, long-range electric vehicle.

Here are all the EVs with 800V charging available in 2024

As technology advances, electric cars are improving their fast-charging times. That means less time spent waiting at a DC public charger when you’re out on the road. While Level 3 chargers used to provide a maximum of 150 kilowatts of power, 350-kW chargers are become more common, making for super-fast charging Â… if your car is capable of taking advantage of it. So how do automakers improve the charging speed of their EV batteries? Some are turning to higher voltage, specifically 800V charging. What's the difference between 800-volt charging and 400-volt charging? So how does 800V charging improve upon the more common 400V EVs? Put simply, the higher the voltage, the less amperage (current) it requires to charge. In other words, with more voltage, you get more wattage (power, aka charge rate) from the same amperage (current). 800V architecture is also more efficient, with less electrical resistance, so it can use thinner cables and smaller, lighter components while needing less cooling. The tradeoff is that it is more costly, and guess who that cost gets passed on to. While automakers don't break down their pricing to show how much more you're paying for that 800V system, you'll just have to evaluate any potential purchases as a whole, and make your decision based on overall pricing of the vehicle. Thankfully, the 800V EVs on sale now are generally ones we like. Now, 800V charging capability doesn't necessarily mean an EV has 800V vehicle architecture. For instance, the GMC Hummer EV and Chevy Silverado EV operate at 400V, but with their dual battery packs, can switch to 800V when charging by temporarily connecting those packs in series. Currently, there are only a handful of EVs available with 800V charging. But if you are going to find yourself taking longer trips in your EV and using DC fast chargers more often, you might want to consider choosing one with this faster charging capability. With that in mind, these are the EVs available with 800V charging, either on sale now or coming in 2024. 800-volt EVs available in 2024 Audi E-Tron GT Chevrolet Silverado EV Genesis GV60 Genesis Electrified G80 Genesis Electrified GV70 GMC Hummer EV Pickup GMC Hummer EV SUV GMC Sierra EV* Hyundai Ioniq 5 Hyundai Ioniq 6 Kia EV6 Kia EV9 Lotus Eletre* Lotus Emeya* Lucid Air Lucid Gravity* Porsche Macan Electric* Porsche Taycan Ram 1500 REV* Tesla Cybertruck *Coming later in 2024 Green Audi Chevrolet Genesis GMC Hyundai Kia Lotus Porsche Tesla Electric Lucid EV charging
