GM ending stop-sale order on heavy-duty trucks

General Motors responded to an inquiry from Autoblog regarding a stop-sale order on its full-size heavy-duty pickup trucks. Here's GM's official statement. GM is committed to building the highest quality products possible. We paused delivery on a small number of HD pickups with the 6.6 liter Duramax engine last week to finalize an investigation into a potential quality issue. The investigation has been completed and the stop sale will be lifted for the small number of vehicles at dealerships.Customers can be assured GM’s heavy duty pickups are covered by a 5 year/100,000 mile powertrain warranty. The original article continues below. General Motors has reportedly sent its Chevrolet and GMC dealers a stop-sale order that applies to some examples of the 2022 Silverado HD, the 2022 Silverado MD, and the 2022 Sierra HD. The units affected by the stop-sale order may develop an engine-related problem. Citing anonymous sources, website GM Authority wrote that the Duramax 6.6-liter turbodiesel V8 in the affected trucks can hydrolock, which means liquid could enter the cylinders and cause a substantial amount of damage. The report does not specify where the liquid would come from; hydrolocking can happen by driving through a deep puddle of water, for example, but a large amount of coolant can cause it as well. The publication adds that the stop-sale order was assigned internal reference number N222362910. It also notes that the trucks included in it can't be sold, delivered to buyers, traded with another dealer, sent to auction, or even used for demonstration purposes until further notice. Earlier in April 2022, GM Authority reported that General Motors planned to buy back an unspecified number of Silverado HD and Sierra HD trucks due to quality-related issues with the 6.6-liter V8. Details about the problems experienced by customers haven't been released; all we know is that each truck will be replaced, though the replacement may not have the same equipment due to the ongoing chip shortage.

Six-week production shutdown planned for 2016 Chevy Volt

It's no surprise that GM is winding down production of the first-gen Chevy Volt as it prepares to start building the second-gen for a launch in the second half of this year, but for now, things are proceeding as planned, according to Chevrolet spokesperson Michelle Malcho. Malcho told AutoblogGreen that GM "is still making first generation Volt" and that there has been no announcement about when that will change. The only details she would divulge is that, "It will be this summer." "Halting Chevrolet Volt production in anticipation of the all-new 2016 model year is a smart move for GM," Akshay Anand, an analyst at Kelley Blue Book's KBB.com, said in a statement. "[The move] allows for less inventory and incentives on the outgoing model. Hybrid and alternative fuel vehicle sales have been declining for some time now, with gas prices well below the summer prices of 2014." Volt production will cease in the weeks before the traditional two-week auto plant shutdown over the July 4 holiday. A high inventory of Volts is a factor in the production cuts, but not the only one, Malcho said. The plant construction, engineering changes and pre-production plans for the new Volt and CT6 all were part of the decision, she said. Nationwide, there is about a 200-day supply of Volts on dealer lots (roughly 100 days in California, the car's biggest market), according to the Detroit Free Press, which says there will be a six-week retooling period (twice as long as normal, but other sources say the shutdown will be four weeks long) at GM's Hamtramck plant this summer to get ready for the second-gen model. The 2016 Volt will get an increase in all-electric range to 50 miles and will then get 41 miles per gallon when the battery runs out. It also has a fifth seat that straddles the battery tunnel and a larger li-ion battery. Related Video: The AP contributed to this report.

Race Recap: Rolex 24 at Daytona was fast and feisty

Let the record show that victory at the 2015 Rolex 24 at Daytona went to the No. 02 Chip Ganassi Racing with Felix Sabates Target/Ford EcoBoost Riley DP driven by Verizon IndyCar drivers Scott Dixon and Tony Kanaan and NASCAR drivers Jamie McMurray and Kyle Larson. The winner did 740 laps to cover 2,634.3 miles in 24 hours and 57.667 seconds. That's a statement to this year's pace in spite of 18 cautions, two more than last year: the Michael Shank Racing Ligier got pole with a time of 1:39.194, slower than last year's pole time of 1:38.270; however, the winning car last year only did 695 laps. The fight for top honors was shaved to a four-car battle over the first third of the event. The No. 02 Ganassi car took the lead on the first lap, swapping it well into the night with the No. 01 Ganassi car, the No. 10 Wayne Taylor Racing Corvette DP, and the defending champion No. 5 Action Express Corvette DP, all of them staying within about 20 seconds of one another. The Action Express car had a fuel connector come loose and lost three laps getting towed back to the pits to have it reattached, but was back in the lead 18 hours in. The No. 01 Ganassi car dropped out with recurring clutch problems 22 hours in, retiring not long after. A race-within-the-race is where the concluding action happened, a seven minute, 30-second dash from the end of the last caution to the checkered flag. During the penultimate pit stops with an hour to go, Dixon was in second place followed Jordan Taylor in the Wayne Taylor Racing DP into the pits but beat him out, taking the lead. The Action Express car was in third. In the last pit stops of the race, Dixon gained even more time, getting a four-second advantage over Taylor. Then a full-course caution came out twenty minutes before the finish when a Prototype Challenge car hit the wall and caught fire, bunching up the field. That closed the pits, but the Wayne Taylor Racing car had to pit during that yellow because of a miscalculation of driver time. No driver can be behind the wheel for more than four hours in a six-hour period but Jordan Taylor was going to go over, so he came in to swap out for brother Ricky. That cost the team any chance of second place, since they took an additional drive-through penalty for entering closed pits. When the track went green again, Sebastien Bourdais in the Action Express car stayed all over Dixon for the final five laps but couldn't get around him.
