Automatic Stop-Start Removed In Some 2021 Chevy Silverado, GMC Sierra Pickups

Pickup truck customers eager to ditch automatic engine stop-start will be happy to learn that General Motors is removing the feature from some 2021 Chevy Silverado 1500 and 2021 GMC Sierra 1500 models. The change stems from the ongoing global microchip shortage.

According to the automaker, most vehicles built on or after June 7th, 2021 with a V8 engine and 10-speed automatic transmission (RPO code MQB) will not be equipped with automatic engine stop-start. As such, RST, LT Trail Boss, LTZ, and High Country trim levels among 2021 Chevy Silverado 1500 models, as well as SLT, AT4, and Denali trim levels among 2021 GMC Sierra 1500 models are affected.

More specifically, the change affects 2021 Chevy Silverado 1500 RST, LTZ, and High Country trim levels equipped with the naturally aspirated 6.2L V8 L87, as well as LT Trail Boss models equipped with either the naturally aspirated 6.2L V8 L87 or the naturally aspirated 5.3L V8 L84.

With regard to 2021 GMC Sierra 1500 models, the change affects SLT trim levels equipped with the naturally aspirated 6.2L V8 L87, as well as SLT trims equipped with naturally aspirated 5.3L V8 L84 and 10-speed automatic transmission (requires SLT Premium Plus package or Texas Edition SLT Premium Plus Package). Affected Sierra trims also include AT4 models and Denali models equipped with either the 5.3L V8 or 6.2L V8.

To note, the naturally aspirated 6.2L V8 L87 produces 420 horsepower at 5,600 rpm and 460 pound-feet of torque at 4,100 rpm, whereas the naturally aspirated 5.3L V8 L84 produces 355 horsepower at 5,600 rpm and 383 pound-feet of torque at 4,100 rpm.

According to the Senior Manager, Product and Brand Communications for Chevrolet, Kevin M. Kelly, dealers recently received a notice about the change, summarized as:

“By taking this measure, it will enable us to continue production of our high-demand full-size SUV and pick-ups as the industry continues to rebound and strengthen. Most of the affected vehicles will experience a minor reduction in fuel economy and customers will receive a $50 (U.S.) credit on the MSRP for affected vehicles.”

The dealer communication continues, addressing the chip shortage by saying:

“Our supply chain organization continues to make strides working with our supply base to mitigate the near-term impacts of the semiconductor situation. GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including our highly profitable full-size trucks and SUVs for our customers. However, the semiconductor situation continues to remain fluid globally.”

  1. No $50 credit like when they deleted DOD?

    1. Honestly, I’d think most people might be willing to pay $50 to have it removed.

  2. Not to mention the cheesy Trail Boss sticker on a $60,000 truck? Come on Chevy. It took decades to finally make the Z71 sticker into a tough looking emblem on the hood, only to be followed by the cheap looking trail boss sticker. Does it take that long to make a mold for a better looking Trail Boss emblem?

    1. It that why people buy those packages? A sticker on the side?

    1. Aren’t you tired of telling us about this yet?
      What will you complain about in a couple years when they’ve redone the interior?

  4. Someone wants gm to build a RCSB as much as i do. I see that red one pictured a lot. Make mine in Tangier Orange Please. When electrics get here, footprint size won’t matter.

  6. GM in 2016:

    “General Motors will expand its use of engine stop-start systems to nearly all models sold globally by 2020. The move is partially influenced by the EPA’s decision to give compliance credits towards Corporate Average Fuel Economy (CAFE) levels to vehicles that include stop-start systems.

    Including the system can improve city fuel economy by six percent in urban driving conditions, while adding roughly $300 to the cost of a vehicle.”

    GM in 2021:

    “Most of the affected vehicles will experience a minor reduction in fuel economy and customers will receive a $50 (U.S.) credit on the MSRP for affected vehicles.”

    Not that I’d ever want that system on my truck but, if they’ve managed to decrease the installation cost of just one system to 1/6th it’s original cost, why are pick-up trucks priced as high as luxury cars these days?

    1. Their parts cost isn’t $50 because many of the parts are still there and can’t be removed without a redesign. Things like electric coolant pumps, beefier starters, transmission fluid pressure accumulators. The problem is they’re missing the electronics to run it.

  7. Nate “Shockandvawe” can’t impress anybody so he impress himself! LoL… Anyway you don’t like the the interior go buy a butt ugly Tundra the inside of a Tundra might be nice but that exterior yuck decide on an angle straight or slopped and get rid of the giant Toyota badge and cheap wheels, and the ugly TRD sticker. I would take a Chevy over any other truck any day. Now that start stop is gone it’s even better.

  8. Jesus Christ in a Chicken basket. Why don’t they make Auto Stop Start something you can disable by pulling a fuse. Having to press a button EVERY SINGLE TIME you start the vehicle is ridiculous.

    Ford, you too!

    Down here in Phoenix , @117F (forecast for Friday) you do not want your AC slowing down at stop lights.

    1. It won’t turn off it he cabin temperature is too high and the a/c is running on high. Mine rarely stop in the summer with a/c on unless i have been driving on the highway and then come to stop on a exit. It also starts right back up if you just turn the A/c one degree up.

    2. EPA regulations say that it has to act the way it does (default on) if they want to get the CAFE credit.

      Reply
  9. Talk about an addition by subtraction, this is it. It will not only reduce the inflated vehicle sticker-price by $50 but save the owners who quickly become fed-up with this nonsense the expense of purchasing one of the aftermarket gizmos that defeat the asinine stop/start bunk that is guaranteed to wear out your vehicle’s starter prematurely.

  10. It’s funny that a chip shortage can be a “good thing.” People pay over a hundred bucks to get rid of it! Talking about the Toyota TRD sticker….( I don’t know how everyone has missed this one?) The first time I saw one, I’m saying to myself, “What does TRD stand for?” “OHHHH, they forgot the U!” “T-U-R-D!”

    Reply
  11. It’s about time. I wish I did not have it on my last two GM products. HATE IT. It retards my driving ability. Especially at stop lights. A hazard at best! Currently have a 2019 Equinox.

  12. The fix is very easy. Make things in AMERICA. By Americans. When will you learn that China and Mexico are not our or your friends.!

  13. Supposedly (LOL) saves on fuel usage, plays HELL with battery & starter life.
    Need to put a STOP button on the EPA!!!

    Reply
    1. The battery and starter are beefed up for this purpose. Seems no one reads about how these things work. Very few issues with the autostop in any of the car manufactures vehicles. GM’s only mistake was not putting a button to turn it off when they first released it.

      1. It would’ve been simpler to just use a dedicated spot on the prndl for an s/s disable drive. Lots of people see no benefit to pushed fuel saving techs. EPA’s test cycle blows & they’re liars. Dohc and turbo are part of the bs too. Regulations are set up to demonize gas engine displacement. Boost wastes fuel, adds cost. Rev up for power wastes fuel, adds cost. The cost also being buyers that prefer displacement. An easy reason to despise most new Ford stuff.

    2. I’ve often wondered where people come up with this myth. But, to be honest who is more clueless? The person that makes a false statement like the above or the people that agree with them?

  14. This is also affecting the 2021 Escalade as well.
