The 2020 Cadillac XT4 is the subject of a safety recall due to potential inactivation of the brake assist system.
The problem: the XT4 was the first Cadillac ever to be fitted with the Electro-Hydraulic Braking Assist technology (EHBA), also known as e-Boost. The material used in a sensor connection in the electronic brake boost system may have been contaminated during the material supplier’s production process. This contamination may cause an interruption in communication between the sensor and the brake boost system under certain conditions. The lack of communication may in turn mean that the vehicle’s electronic brake boost assist could be lost.
The hazards: this issue does not affect the braking performance of the Cadillac XT4. However, the purpose of brake boost assist is to provide more braking than the driver has applied if the vehicle senses that this would reduce the chance of a collision. That chance increases if the system fails.
The fix: Cadillac dealers will replace the electronic brake boost module.
Affected vehicle: 2020 Cadillac XT4.
Number of affected vehicles: Cadillac parent company, General Motors, has not included the number of affected vehicles in its recall notice.
Affected component: electronic brake boost module.
Next steps: owners should expect a recall notice in the mail and can contact their Cadillac dealer or Cadillac customer service (phone number below) with any questions.
Vehicles involved in this recall that are in dealer’s stock were placed on stop delivery on September 24th, 2020. Once the electronic brake boost module has been replaced, the vehicle is released from stop delivery and can be delivered to the customer.
