Why GM is Ordering Dealers to Stop Selling 2020 Chevrolet Corvettes

A problem with brake sensors is causing General Motors to recall a few different models. The failure of the sensors could cause drivers of the high performance cars to crash.

General Motors is ordering all dealers to stop selling any 2020 Chevrolet Corvettes in inventory until it can recall and fix a brake sensor. That’s according to a C8 Corvette Forum called Corvette Action Center. The forum has apparently gotten a hold of the bulletin that has been sent to dealers.

Brake Sensor Causing the Stop Sale Order

According to the information on the Corvette Action Center website, the brake assist sensor on the cars could fail to work because of debris on the sensor. The problem can also affect some 2020 Cadillac CT4, CT5 and XT4 models, 2020-2021 Buick Encore GX vehicles and 2021 Chevrolet Trailblazer models. The dealer bulletin says in the FAQ section “Material used in a sensor connection in the electronic brake boost system in these vehicles may have been contaminated during the material supplier’s production process. Contamination of this material may cause an interruption of communication between the sensor and the brake boost under certain conditions.”

In other words, the sensor sends a signal to the brake assist to help slow or stop the vehicle. If the sensor doesn’t work properly, the vehicle may not slow down or stop in time to avoid a crash.

GM is currently working with the supplier so they can recall and replace all of the potentially faulty electronic brake boost modules.

General Motors Bulletin to Dealers

According to the website the bulletin reads, “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 (NTHSA) about an upcoming safety recall that involves these vehicles. The GM recall number is A202307260.”

How GM Will Fix the Problem

GM will notify all of the affected owners of the vehicles about the recall. Once they have enough supplies on hand, the dealerships will replace all of the potentially contaminated electronic brake boost modules. To find out if your vehicle is affected, you can check the NHTSA website.

In the meantime, owners of the vehicles named in this potential recall should be aware that they may need to push much harder on the brake pedal, in case the electronic brake boost fails. The bulletin does not say if there have been any crashes or injuries reported.

As Torque News reported, in August, the stunning 2020 Chevrolet Corvette also recently had a recall involving the front hood potentially flying open.
