Safety Recall
N222375270 Brake Pressure Switch Connector Fire

 

Condition

General MotorseBay has decided that a defect which relates to motor vehicle safety may exist in certain 2019-2023 model year Chevrolet Silverado Medium Duty 4500HD/5500HD/6500HD vehicles. These vehicles may have a brake pressure sensor assembly that allows brake fluid to leak beyond the diaphragm seal into the pressure switch. The brake fluid may seep into the sensor’s electrical components and short the brake pressure switch and the associated fuse. If brake fluid shorts the brake pressure switch and the associated fuse, the circuit can generate excessive heat that could result in a fire, increasing the risk of injury. An underhood fire may occur when the vehicle is off and possibly unattended.

 

Correction

Dealers will replace the master cylinder pressure sensor. Dealers will also inspect the associated wire harness and replace if necessary.

Chronology :

On August 9, 2022, GM opened a product investigation following a claim of a vehicle fire on a 2019 Chevrolet Silverado Medium Duty vehicle. As part of that investigation, GM coordinated with Navistar, the manufacturer of the subject vehicles, to review field data and warranty returned brake pressure sensors.

While a series of tests failed to duplicate the SUFS vehicle’s condition, on January 25, 2023, a warranty returned sensor and harness was identified which exhibited signs of heat damage. This part was subjected to more detailed analysis, including X-ray scans which were completed on February 13, 2023, followed by chemistry laboratory analysis which was completed on February 28, 2023. The results from these analyses revealed the presence of brake fluid past the diaphragm seal, into the brake pressure switch and through the actual wire harness into the pump’s fuse circuit. Analysis of the returned components also revealed delamination of the corrosion inhibiting sealant, which allowed slow seepage of the brake fluid past the diaphragm seal.

On March 30, 2023, Navistar reported one potentially related field incident involving a part with alleged heat damage. On April 5, 2023, Navistar provided GM a list of potentially affected vehicle VINs.

On April 6, 2023, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall. GM’s final analysis of the field data, including legal claims, identified a total of twenty-one potentially related complaints, eleven of which alleged a fire, smoke, or flame. GM was provided notice of those events between July 26, 2021, and January 25, 2023.

GM is not aware of any accidents or injuries associated with this condition.
