| Service Brakes problems |
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.
I purchased a new 2026 Jeep Grand Cherokee on may 9, 2026. On June 4, 2026, less than one month after purchase, the vehicle experienced a sudden brake system failure while I was driving. The brake pedal became hard and unresponsive, the abs warning lights illuminated, and the vehicle had very limited stopping power. Fortunately, I was able to safely drive the vehicle to the dealership without an accident or injuries. The dealership diagnosed the problem as a failed brake booster (part # 68734134ab) requiring replacement. However, the replacement brake booster is on backorder, and stellantis has confirmed that there is currently no estimated delivery date and no assigned distribution for the part. As a result, my vehicle has been out of service for 4 weeks with no repair timeline. Stellantis has acknowledged that this involves a critical safety component but has been unable to provide a meaningful resolution beyond monitoring the backorder. I continue to make lease payments, insurance payments, and other vehicle-related expenses for a brand-new vehicle that I cannot safely operate because of a warranty-covered safety defect. This is a serious safety concern because the failure involved the vehicle's braking system and significantly reduced the vehicle's ability to stop. Had this occurred at highway speeds or in heavy traffic, the consequences could have been catastrophic. I am submitting this complaint because I believe this brake system failure warrants investigation to determine whether it affects other 2026 Jeep Grand Cherokee vehicles and whether the lack of availability of replacement brake boosters for a critical safety component creates an ongoing risk to consumers. A vehicle with a brake system failure should not remain out of service indefinitely because a safety-critical replacement part is unavailable.
