2022 GMC Hummer EV voluntarily recalled for battery connector issue

When vehicles from certain automakers need to return to dealers for fixes but the National Highway Traffic Safety Administration isn't involved, these situations might be called "Customer Satisfaction Programs." It is, effectively, a voluntary recall. GM Authority notes that GM has issued one such program for the GMC Hummer EV and the Brightdrop Zevo 600 van (formerly the EV 600) to deal with a battery issue. In roughly 424 total units across both populations, the high-voltage connector might prematurely corrode. If this happens, water can leak through the connector into the pack. A warning light in the gauge cluster will alert owners to the condition. GM doesn't outline the possible results of water getting into the pack, but the outcome wouldn't be ideal.    The fix is a trip to the service bay to have a technician apply sealant to the high-voltage connector.   GM says it will get in touch with Hummer EV and Brightdrop owners about making appoints with dealers. Meanwhile, owners can contact GM Customer Service at 800-462-8782 and refer to Satisfaction Program No. N222362090. Owners can also visit the GM Recall Center page and insert their VINs to find out if their vehicles are affected. Since this isn't a recall overseen by the NHTSA, the issue isn't covered on the NHTSA's site. However, there are Manufacturer Communications between GM and the NHTSA related to other H2 issues such as a calibration issue with the Hummer EV's Extract Mode and the HVAC, so owners might want to visit SaferCar.gov for the whole picture.

GM delays 3.0-liter Duramax diesel in Silverado and Sierra pickups

Stricter testing protocols around the world are making it harder for automakers to predict launch timelines. GM is the latest to get caught in emissions nettles, the Detroit carmaker forced to delay the launch of its new Duramax 3.0-liter inline-six diesel for the Chevrolet Silverado 1500 and GMC Sierra 1500. That's what company reps told dealers in a memo seen by Automotive News this week. Dealers and buyers had been promised the Flint, Mich.-built oil-burner in early 2019, but AN wrote that the EPA certification hiccup has turned into a "slight delay." A GM spokesman told Motor1, "[We] did not attribute [the delay] to a single entity, as the truth is this is a collaborative effort between GM and several government entities. We will make the 2020MY Duramax available for dealers orders soon, and expect to deliver the first trucks to customers soon after emissions testing is complete." We know the new 3.0-liter Duramax diesel has 277 horsepower and 460 pound-feet of torque, outdoing Ford's 3.0-liter PowerStroke diesel by 27 hp and 20 lb-ft. But without final EPA paperwork, GM can't release the numbers that will show how the two engines stack up when considering fuel economy and tow ratings. The certification process has been sticky for a few other makers of late, especially since the Volkswagen Group situation in 2015. BMW had to delay the launch of four diesel models in 2016 over EPA testing. The new Ram 1500 dribbled out in a trickle last year for reasons thought to deal with EPA testing, coming as it did a year after the EPA investigated Ram's EcoDiesel engines in 2017 and 2018. More recently, WLTP testing in Europe caught out just about every automaker over there. Since we're almost halfway through 2019, the delay until the 2020 model year is only a few months. Still, GM told dealers to cancel any orders for the engine for this model year. Dealers will need to resubmit the orders once opening begins, but GM hasn't said when production will begin other than "soon." The company said that it will offer 2020-model-year replacement vehicles to customers and dealers. If prices hold into the next model year, the 2020 Silverado 1500 and Sierra 1500 with the inline-six diesel will come at a $3,890 premium over the 2.7-liter turbo four-cylinder, and a $2,495 premium over the 5.3-liter V8.

2015 Chevy Silverado, GMC Sierra recalled for steering issues

DETROIT — General Motors Co is recalling more than 1 million pickup trucks and sport utility vehicles in the United States due to issues with a temporary loss of power steering, the National Highway Traffic Safety Administration said. The recall is for 2015 models. They are: the Chevy Silverado 1500, Suburban and Tahoe, GMC Sierra 1500, Yukon and Yukon XL and Cadillac Escalade. The problem may cause difficulty steering the vehicle, especially at low speeds, increasing the risk of a crash, the auto safety regulator said in a document dated Sept. 12. The document did not highlight any reports of accidents and injuries, because of the power steering issue. GM dealers will update the power steering module software, free of charge for owners of the affected vehicles. In 2014, the No.1 U.S. automaker had recalled nearly 800,000 pickup trucks worldwide because of the same problem. GM did not immediately respond to a request for comment.Related Video:
