Electrical system

Air bags

1 report1 crash
“On 7/17/2026 I was involved in a motor vehicle crash resulting in damage to both my Jeep Wagoneer and the other vehicle. I was informed that I have a recall on my Electronic brake assist and the brake system control module for my Wagoneer today August 6th, 2026. I'm wondering if the faulty brake system control module contributed to the crash. I am unable to complete the recall repairs until after my wagnoeer is repaired after the resulting motor vehicle crash. I had no prior warning, messages, or problems prior to the failure. Also to note--I hit my head on my side driver door and sustained significant impact to the front fender wheel (driver side) and my air bags did not deploy. The resulting damages to my car are estimated at 19,000”
