2020 Jeep Gladiator

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.

While I was driving the vehicle, the instrument cluster screen went completely blank and it won’t display any information like the speed, gas or anything about the vehicle information. Went completely blank while driving the vehicle, which could’ve caused an accident.

Instrument Panel Cluster (IPC) Failure. The central Instrument cluster display went blank without warning unable to see fuel gauge, Temps and other gauges and warning lights are normally illuminated while the vehicle is in operation.

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 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 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.

The instrument cluster has gone black.

Intake lifters seizing and or rockers needle bearings failing resulting in camshaft lope damage

Jeep will not include my vehicle in the Instrument cluster failure because they predetermined which vin numbers were affected and did not include my 2020 Jeep Gladiator on the list. But my vehicle clearly has the electrical problem causing the center instrument cluster to not work and be blank. I cannot see how many miles I drove or how much gas is in the tank and cannot see anything outside of MPH and RPM.

INSTRUMENT CLUSTER WENT BLACK

The contact owns a 2020 Jeep Gladiator. The contact stated that while driving at various speeds, the instrument cluster failed to display the odometer or safety features as intended. No warning light was illuminated. The vehicle was taken to a local dealer where it was diagnosed and determined that the instrument cluster needed to be replaced. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Investigation: PE25014 (Electrical System) and NHTSA Campaign Number: 24V652000 (Electrical System); however, the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was approximately 56,000.

Front defroster only blows in the center and does not distribute air to the sides of the front windshield when the driver looks out.

Engine failure due to coolant leak: in December, 2025, vehicle was towed to dealership due to overheating engine. While driving home from work, Vehicle was exhibiting engine overheating including temperature warning lights, temperature gauge fluctuating from normal to extremely high, a strange sound coming from the front of the vehicle (almost like a fan was not working) and running rough, like a diesel idle. I immediately pulled the vehicle off to the side of the road & shut it off. (Fortunately engine didn’t seize or exhibit these symptoms while I was on the highway just minutes before) I called dealership & they said it needed to be towed in. After having my vehicle for 10 days, Dealership stated thermostat needed to be replaced. Vehicle then exhibited same symptoms a few weeks later along with a check engine light, vehicle is returned to dealership. Dealership NOW tells me they’ve “seen enough of these to know that it’s most likely going to need a left side cylinder head” due to coolant leak into the engine. I am now aware there have been multiple reports to NHTSA for similar issues and that a service bulletin has been issued to the dealerships for this very reason: its a KNOWN issue with no recall in sight. Jeep at this juncture, acknowledging it’s a problem, REFUSES to assist with very costly repair, instead suggesting I should report to NHTSA.

digital dash cluster became erratic then blacked out entirely. Restarting vehicle didn't help. Cannot see fuel gage nor safety alerts any more.

The digital gauge cluster went blank and does not display any important information. 32k vehicles have been issued a recall but my VIN was not included. I also heard that 90k+ other vehicles had the same problem but new recall was not issued.

Instrument panel cluster has gone black. Checked fuses and they are well seated.

Our dash board has gone black and we can not see how fast we are going how much fuel we have or the milage or anything else on the dash. The radio still works but nothing else on the dash is working. there are 32,000 other vehicles with recalls on this same issue our truck does not fall under the recall batch but obviously should. this is a major safety issue
