Chevy Silverado HD, GMC Sierra HD Duramax Stop-Sale Order Lifted

GM has lifted the stop-sale order that was effective on the Chevy Silverado HD and GMC Sierra HD pickups equipped with the 6.6L V8 L5P turbodiesel Duramax engine.

GM dealers were informed on April 26th that the stop-sale order on certain Silverado HD and Sierra HD trucks, which had been active since March 17th, had been lifted. GM Authority was first to report on this stop-sale order, which was issued due to a potential hydrolock/no-start issue in roughly 3,500 Duramax-powered 2022 Chevy Silverado HD, GMC Sierra HD, and Chevy Silverado MD (4500HD / 5500HD / 6500HD) units.

With this change, GM dealers are once again permitted to sell affected trucks to customers. Dealers will also now be able to deliver customer trucks that were on order before the stop-sale but had gotten wrapped up in this quality control protocol.

GM Authority reported previously that GM had agreed to repurchase certain units of the Chevy Silverado HD and GMC Sierra HD due to apparent quality issues with the 6.6L L5P V8 turbodiesel Duramax engine. Although GM has agreed to replace affected trucks, replacement vehicles are subject to feature constraints as a result of the ongoing global microchip shortage, which limits the availability of features like heated and ventilated front seats, heated outboard rear seats, heated steering wheels, and Front And Rear Park Assist. While GM has not confirmed as much, it seems likely this issue is related to the one that caused the stop-sale order.

6.6L L5P Duramax Turbo Diesel V8

The 6.6L V8 L5P turbodiesel Duramax is rated at 445 horsepower and 910 pound-feet of torque, enabling a maximum towing capacity of 36,000 pounds in properly configured Chevy Silverado HD and GMC Sierra HD models. The diesel eight-cylinder is produced at the DMax Ltd. engine plant in Moraine, Ohio as part of a joint venture between GM and Isuzu Diesel Services of America, Inc. The latest L5P iteration of this engine went into production at this facility in 2016 for the 2017 model year.

  1. Today, May 2nd, my buddy who owns and drives a taxi in Toronto, said that he saw one name brand gas station selling diesel fuel for $2.25 per liter. People don’t do the math to really compare our pump prices in American dollars. Since there are 3.7854 liters in a USA gallon, that $2.25 cost is $8.668 per gallon. Apparently the pump price of diesel fuel rose by 40 cents a liter just last week. This is not justified in any way for Canada. How much is that 40 cents in USA gallons? It’s an increase of $1.514 in just one week, yet the wholesale price of oil went down a couple of dollars. Once again there’s no justification for the HUGE price increase at the pump. Remember that on April Fool’s day, the 4th year of the Trudeau carbon tax moved up another level. Forget the talking heads and the media, it’s a smokescreen about the real cost of carbon tax. After 4 years, that 6 cents per liter plus HST in Ontario of 6.78 cents per liter equals $1.0266 per USA gallon. Who knows how much per ton for the carbon tax? I have paid very close attention to this Trudeau carbon tax since is was first under consideration and i have not taken my eyes off of it. It’s the Liberal Party of Canada and the NDP who back them up, are at fault for that $1.03per USA gallon carbon tax. ESSO known as Imperial Oil Corp in Canada, has stated in the past that the Ontario price for fuel is based on the New York Harbour price. Guess what, the EIA administration of the USA government showed that the pump price of diesel fuel in the PADD area which is New England and includes NJ, NY, MASS and NH, CT, Vermont etc. The EIA showed a huge jump up in price of diesel fuel by 86 cents in a one week period. The EIA polls are taken all week and compiled on Friday then the prices are released on Monday’s So, it seems that the whores setting the pump prices in the USA are responsible. But why only 86 cent increase in the USA ( $1.11 in Canada funds )and yet the pump price in the Toronto area went up by an extra 40 cents higher than the American increase. It’s clear that the oil refineries on both sides of the border are screwing the public. Call the PR departments of each major refinery and bitch every day. It’s not just Trudeau screwing with you. Stop using diesel fuel and start using high octane propane in your 2500 and 3500 series trucks. The pump price of propane is less than $1.15 per liter and it’s 104 octane and 37 percent hydrogen.

    1. Got you beat.
      But winning in this case is not good.
      I paid 2.36 here in Halifax
      Don’t forget that Trudeau has put the tax up since the first round.
      Then we have Provincial tax and federal tax and one other tax on fuel.
      The killer is that cars and trucks are the least polluting of all the fossil fuel we burn.
      They are not where the government should be spending there time.
      Power plants that burn coal and oil are the most polluting and problematic in the world for producing carbon.
      Air travel is extremely high also.
      There is 5000 planes in the air over the USA at any given time.
      Nether Canada or the USA power grid can handle the switch to EVs
      All this tax will cause massive inflation.
      Trudeau is a millionaire and these prices have no effect on him or anyone else that make up our over paid and compensated politicians.
      Trudeau needs to go….

  3. See the USA in a CHEVROLET!! I remember that commercial so clearly. Don’t remember the year though.
    I live in the lower mainland in Vancouver BC and with the “INSANE” fuel prices, I don’t see much of a reduction in traffic on the roads, or for that matter any increase in the number of “Campsites” available in the US and Canada. People will “DRIVE” because they enjoy it (except in traffic jams) and public transportation is NOT efficient in most places. I also think you see so many single occupancy vehicles on the road because people want some private and quiet time for themselves and their vehicle is an “ESCAPE”!
    Politicians are usually wealthy coming in and even more going out so few really care or know what the stresses the “working person” deals with every day. That is NOT likely to change.

    It is sad that the public get hammered in the places that bring us the most pleasure like our vehicles.
    Life goes on and we can only do the best we can. Be should be grateful we are healthy enough to be able to enjoy our personnel transportation.
