GM Issues Stop Sale Order for the 2020 Corvette and Other Vehicles Over Brake Sensor Issue


Our friends over at the Corvette Action Center have some breaking news this evening regarding the 2020 Corvette. According to the report, GM has issued a Stop Sale Order to halt the deliveries of the 2020 Stingray over an issue with contamination in the electronic brake boost system sensor which can cause a communication breakdown between the sensor and brake boost system.

According to the stop order, the contamination issue affects multiple GM vehicles including models from Buick, Cadillac, as well as the Chevrolet Trailblazer.

As we learned with the previous Stop Delivery Order, GM notifies the National Highway Traffic Safety Administration (NHTSA) that a recall will be issued for the specific vehicles. We checked out the NHTSA website and they do not have it yet listed. If you have questions, you can search your VIN at https://my.gm.com/recalls to see if your Corvette is one of those flagged for recall.

Unfortunately, this does look like a hardware problem that will require a dealership visit. The two previous recalls for the 2020 Corvette were concentrated on the frunk with both issues solved with an over-the-air update to owners and dealers to correct the issues.

From the Corvette Action Center:

Effective immediately, stop the delivery of certain 2020-2021 model year Buick Encore GX, 2020 model year Cadillac CT4, CT5, XT4, Chevrolet Corvette, and 2021 model year Chevrolet Trailblazer vehicles in new or used vehicle inventory. General Motors has notified the National Highway Traffic Safety Administration (NHTSA) about an upcoming safety recall that involves these vehicles. The GM recall number is A202307260.

Material used in the manufacturing process of the sensor connection can exist which may cause an communication breakdown between the sensor and the brake boost system.

A list of affected vehicles in dealer inventory has been sent to Chevy dealers and GM is working with the supplier to acquire the necessary parts to conduct repairs.

Along with the notice to dealers, GM sent a list of FAQs to answer any customer concerns:

  1. My new C8 was supposed to have been built this week, now I cannot get a straight answer as to how this will affect my build and delivery date.

  2. I guess my car will have its first recall before I even get it. GM is so screwed up that my dealer isn’t sure if my car has been shipped yet.

  3. GM has major issues with it’s modules. I don’t know who supplies them with those modules but they almost always fail. More issues for the C8 will cause further delays now!

  4. Chinese own since 2009! Cadillac, Buick and Pontiac as well as the corvette are made in China!! POS!

  5. It just keeps getting worse and worse for my 2020 Convertible in 3000 mode.
    I keep seeing GM advertising huge multi-thousand dollar discounts on all their 2020 models, some up to $6000. but not Corvette.
    Where does that leave us 2020 C8 Convertible waiting owners?
    I think it’s time GM came to the post with some offers/incentives for us loyal ‘waiters’.
    The aspect of receiving a 2020 in December 2020 or maybe even in January 2021 requires some kind of perk.
    Just spitballin’ here, but how ’bout something like this–
    — $5000. year end discount for deliveries after September 30.
    — Option of changing to 2021 at 2020 prices including options and guaranteed early build.
    — One year extention of 2020 warranty provisions. (i.e., 4 year b2b)
    — Voucher for $2000. worth of OEM GM accessories and/or dealer-installed options.
    Do you think GM should step up to the plate in some way?

  6. I still dont see any comments on what is happening when cars are being built as we speak. are they building the 2020 c8 using the “bad” module and if so now what? are the cars being shipped like that and then they just sit in the dealership lots until these parts are available?
    I cant believe its not in the story. So many customers are waiting on their vehicles and this information is not even mentioned?

  7. All the affected Corvettes on the recall were already built. We didn’t know that until after Chevy released the info on affected vehicles to dealers. – Keith

  8. ok so can I ASSume that new vehicles on the assembly line being built right now have the new updated module/sensor? If so why is GM saying the part is not available to customers of affected vehicles?

  9. We’ve had our C8 three weeks. While out we attempted to open the frunk. Didn’t open, however, the car thought it was. Car would not go over 26 mph. Our dealer sent a tow truck to get the car and my stranded husband. Now we’re told it needs a part to fix it, that is back-ordered for possibly weeks. So our brand new Vette sits at the dealer service bay while we were given a loaner, a Trax.
