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.

2024 GMC Sierra EV revealed with 754 horsepower, 400 miles of range

This is the 2024 GMC Sierra EV in all its Denali Edition 1 glory. You probably knew this was coming. After all, when Chevrolet debuts a new pickup, the GMC version of said truck is typically quick to follow. That’s exactly the case here yet again as the Sierra EV follows the somewhat recent debut of the 2024 Chevy Silverado EV. Per usual, the Chevy and GMC versions of the electric truck share a lot of similarities. TheyÂ’re also different in many of the same ways weÂ’re accustomed to within the GM pickup family. The biggest differentiator is design. If the Silverado EV wasnÂ’t your cup of tea, perhaps the Sierra EV is! Just like the Silverado EV, the Sierra rides on GMÂ’s Ultium platform. ItÂ’s being offered exclusively in Crew Cab form at launch. GMC designers emphasized its upright stance and proportions as typical truck styling. However, close examination will show a lot of curved edges and a focus on aerodynamics to achieve a lower coefficient of drag. The front grille is devoid of any flashy patterns, as GMC has opted to go for the shield aesthetic. Light is heavily used to bring a flash of design to the face — the whole grille features a light-up surround. A three-bar charging status indicator can be seen on the front end, and engineers intentionally mounted the headlights lower in the front fascia than usual. For the Denali Edition 1 (the only version of the Sierra EV available at market launch), all of the exterior trim is done in glossy black, except for the areas you might step on, which are finished in a flat black. The rear features GMCÂ’s MultiPro tailgate, and just like the Silverado EV, the Sierra EV comes with the fancy MidGate. GMC calls it the “MultiPro MidGate,” but itÂ’s the same tech used here as youÂ’ll see in the Silverado EV. With the MidGate down, you get nine feet of storage between the cab and the tailgate. Storage can extend out to 11 feet if you use the MultiPro tailgateÂ’s stopper feature with the tailgate down. Also, the MidGate can be folded with a 60/40 split, so you can get that extra length and still retain some backseat passenger room. All of the powertrain and battery tech is similar to the Silverado EV. That means you get a pair of electric motors for all-wheel drive capability with a combined output of 754 horsepower and 785 pound-feet of torque. YouÂ’ll need to be in “Max Power Mode” (we know, much less exciting than WTF mode in the Hummer EV) to realize all that power.

GM issues stop-delivery for 2015 Chevrolet Colorado and GMC Canyon

General Motors is issuing a stop-delivery order for its latest midsize pickups, the 2015 Chevrolet Colorado and GMC Canyon, because the driver's side airbag might not be wired correctly. The total number of vehicles affected is still being determined.
According to the statement from GM, the problem, "affects the vehicles' two-stage airbag system by reversing the deployment sequence and disrupting the deployment timing of the driver airbag stages." That means in an accident the bag may not work correctly.
Most of the affected trucks are still on the assembly line, in transit or unsold at dealers, says GM. Until a way to repair the problem is found, customer deliveries are stopped. However, "a small number" of them are in the possession of buyers. GM is contacting these people by phone and by FedEx letter to have the vehicles returned to dealers. In the meantime, they'll be given a loaner to drive.
