2020 Jeep Gladiator

Instrument Cluster/Dash panel electrical is shorting out and glitching while driving. Lights and messages go off while driving and then when the computer/vehicle resets the codes and lights go away. Then come back again. Garage checked out and could not find any electrical issues with Battery or Alternator and points towards the instrument cluster.

The contact owns a 2020 Jeep Gladiator. The contact stated that while driving at an undisclosed speed, the instrument panel failed to display the speedometer, warning lights, engine oil gauge, and the fuel gauge as needed. The failure had caused the vehicle to run out of fuel several times. The vehicle was taken to an independent mechanic after being involved in a crash while the vehicle was parked, and the mechanic related the failure to NHTSA Campaign Number: 24V652000 (Electrical System); however, the VIN was not included in the recall. The contact was advised to take the vehicle to the dealer. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to report the failure to the NHTSA Hotline. The failure mileage was unknown.

This complaint is a follow-up to NHTSA complaint number 11729095. Since submitting the original complaint, the issue has continued and is now occurring while the vehicle is in motion. The vehicle is experiencing intermittent electrical and communication failures affecting multiple systems. The issue began approximately three weeks ago after completing a normal drive and has persisted since that time, occurring randomly and without warning. Both the main battery and auxiliary battery have been replaced; however, the condition remains unresolved. Current symptoms include: •Multiple warning messages and warning lights activating simultaneously while driving (including “Service Antilock Brake System” and “Service Shifter”) •Loss of communication between multiple control modules •Fault codes that temporarily clear but return •Instrument cluster instability and erratic system behavior Power steering assist becomes intermittent during these events, making steering significantly more difficult, particularly when navigating curves or operating in heavy traffic. This creates a serious safety hazard due to reduced vehicle control. Diagnostic trouble codes associated with this condition include multiple communication-related faults (U-codes), indicating loss of communication between critical control modules. The condition may temporarily improve when the auxiliary battery system is bypassed and the battery sensor is disconnected, but the failures consistently return. The issue is ongoing, intermittent, and reproducible. No accidents have occurred to date; however, the condition presents a clear and increasing safety risk. Photographic evidence of warning indicators and system faults occurring during vehicle operation is available. Root cause remains UNKNOWN but is suspected to involve the auxiliary battery system, battery management system, wiring, or vehicle communication network.

The vehicle is experiencing intermittent electrical and communication failures affecting multiple systems. The issue first occurred approximately three weeks ago immediately after completing a normal drive. Since that time, the problem has occurred randomly and repeatedly. Following the initial event, multiple warning messages appeared, including “Service Shifter,” along with numerous fault codes indicating loss of communication between control modules. Both the main battery and auxiliary battery have been replaced; however, the issue persists with no improvement. Current symptoms include: •Intermittent loss of communication between modules •Repeated warning messages, including “Service Shifter” •Fault codes that temporarily clear but return after driving •Unpredictable and inconsistent vehicle system behavior The condition sometimes temporarily improves but the faults and warnings consistently return. This creates a safety risk due to unreliable vehicle operation, including potential loss of shifting capability, starting issues, or failure of electronically controlled systems while driving. The failure is ongoing and intermittent but reproducible. The vehicle has not been involved in any accidents related to this issue. Root cause is UNKNOWN but suspected to involve the auxiliary battery system, battery management system, wiring, or related electrical components.

The contact owns a 2020 Jeep Gladiator. The contact stated that while driving at an undisclosed speed, the instrument panel went dark and displayed a black screen. The failure obstructed the driver's visibility of the speedometer, fuel gauge, and other components, which prevented the driver from safely operating the vehicle. The vehicle was taken to the dealer, where it was diagnosed with instrument panel failure. The vehicle was not repaired due to the cost. The contact stated that the failure worsened, and the instrument panel was inoperable. The manufacturer was not made aware of the failure. The failure mileage was 47,119.

The side mirror amber lights warning of a vehicle in the blind spot randomly illuminate and remain on for upwards of an hour or upon turning the vehicle off and back on. The dash randomly notifies me that the forward collision warning isn't available and both side mirror blind spot warning lights illuminate for upwards of an hour or until I turn off and restart the vehicle. The Dash randomly goes blank and doesn't display any information such as speed, RPM, warnings etc.

The contact owns a 2020 Jeep Gladiator. The contact stated that while driving at an undisclosed speed, the infotainment screen failed to function as intended. The screen turned black and remained black. No warning light was illuminated. The vehicle was taken to a local dealer and was pending a diagnostic test. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The contact associated the failure with NHTSA Campaign Number: 24V652000 (ELECTRICAL SYSTEM); however, the VIN was not included. The failure mileage was approximately 105,000.
