2024 Jeep Wagoneer S

The high-voltage propulsion system and Battery Pack Control Module (BPCM) failed. The vehicle suffered an abrupt drop in power, overriding driver input and forcing it into "turtle mode." The vehicle is currently un-diagnosed and available for inspection at the Jeep dealership. My safety and the safety of others were put at immediate risk. The vehicle suffered a sudden loss of acceleration in live traffic. This abrupt drop in speed creates a severe hazard for rear-end collisions, as the vehicle could not maintain traffic speeds or accelerate out of danger. The vehicle was towed to an authorized Jeep dealership on August 10th. The dealer missed multiple diagnostic commitments (August 14th and August 24th) and has failed to diagnose or repair the issue for over 16 days. No formal inspections have been completed by the manufacturer, police, or insurance representatives since intake. The vehicle experienced multiple power drops into turtle mode on multiple dates with dashboard warning lamps illuminated. This mirrors known software issues on this platform detailed in Stellantis TSB 08-022-25 REV. B.

Supplemental Update to Complaint No. 11672058 This is an update to my July 8, 2025 complaint regarding a brake booster failure on my 2024 Jeep Wagoneer S. The vehicle has remained in dealer custody at South Pointe Chrysler Jeep Dodge Ram in Tulsa, Oklahoma since June 28, 2025 and is still out of service. Although a brake booster replacement was installed, the dealer has not identified a root cause and has not confirmed that the braking system is safe or reliable. The original defect involved a complete loss of braking while the vehicle displayed a Ready to Drive message, creating a severe safety risk. No assurance has been provided that this condition cannot recur. The issue appears to involve braking and electronic control systems, but no effective resolution has been documented. Due to the unresolved nature of a total brake failure and the continued inability to return the vehicle to safe operation, I am submitting this update for safety defect tracking and potential investigation. The vehicle remains unavailable for use due to ongoing safety concerns.

1. Brake Booster Failure: On [XXX], my Wagoneer S experienced a brake booster failure, rendering the brakes inoperable. The vehicle displayed multiple error messages but still showed a misleading “Ready to Drive” message, falsely indicating it was safe to operate. The SUV was towed to SouthPointe Jeep in Tulsa on June 28, 2025. I was informed the required brake booster part is backordered until at least July 21, 2025, leaving me without a safe vehicle for nearly a month. 2. Uconnect System Freezing During Backup Camera Use: Approximately 70% of the time, the Uconnect system freezes shortly after starting the vehicle, then reboots. Critically, this often happens while backing up using the rear-view camera — the screen freezes mid-maneuver, creating an extreme hazard for collisions with pedestrians or other vehicles. 3. Other Ongoing Problems: Persistent door rattling and poor build quality. Intermittent braking response or acceleration hesitation. Multiple software glitches, contributing to system instability.
