U0155 on Jeep by model: symptoms, diagnosis and fix
The 3.5-inch instrument panel cluster display can fail due to a bad circuit board (made by Marelli) that shorts out internally. Drivers lose speedometer, fuel gauge, engine temperature, turn signal indicators, and other warning lights. NHTSA opened investigation EA25-003 covering over 232,000 Gladiator and Wrangler vehicles from the 2020 model year.
Common Symptoms
- Speedometer stops working or reads incorrectly
- Fuel gauge inoperable
- Engine temperature gauge fails
- Turn signal indicators not illuminating
- Warning lights all illuminate simultaneously
- Intermittent blank instrument cluster display
How to Fix
Dealer replacement of the instrument panel cluster module is the primary fix ($500-1,200 at dealer). Some independent repair shops (such as Cluster Fix) can repair the circuit board for $200-400. Ensure any replacement is properly programmed to match the vehicle VIN and current mileage.
Owner tips & cautions
- TipCheck if your VIN falls under the NHTSA investigation - a formal recall may result in free repairs
- TipCircuit board repair shops like Cluster Fix can refurbish the IPC for $200-400 instead of full replacement
- WarningDriving without a functional speedometer and warning lights is unsafe and may fail state inspection

Early JK Wranglers commonly develop instrument-cluster faults: speedometer, tach, fuel, and temp needles that stick, read erratically, or drop to zero, and in some cases full cluster/CCN module failure. Owners report needles losing their retaining adhesive on the stepper-motor shafts. A high-demand JK electrical search.
Common Symptoms
- Speedometer or tach needle sticks / reads wrong
- Fuel and temp gauges inaccurate
- Needles drop to zero intermittently
- Dead or flickering cluster
- Warning lights on with no fault
How to Fix
For sticking/erratic needles, the cluster is removed and the stepper motors/needles reseated or the board repaired; specialists (e.g. UpFix) offer a rebuild-and-return service. Complete failures require a replacement cluster (must be programmed/mileage-matched to the VIN via a dealer or locksmith tool). Reseat any needle fully onto its driver shaft.

Chrysler recalled 32,863 vehicles — 2018-2024 Wrangler and 2020-2024 Gladiator — because the instrument panel cluster can develop an internal short circuit and fail outright, taking the speedometer, fuel gauge, and every telltale and warning lamp with it. NHTSA classified this as a failure to comply with FMVSS 101, 'Controls and Displays.' Unlike a software-blanking fault this is a hardware defect inside the cluster, and the declared remedy is replacement, not a reflash. Owner notification letters went out between October 3, 2024 and January 23, 2025.
Common Symptoms
- Instrument cluster goes completely dark
- Speedometer, tachometer and fuel gauge inoperative
- All warning lamps and telltales lost
- Intermittent cluster flicker before total failure
How to Fix
Have the dealer perform Recall 24V652 (FCA 30B) — full instrument panel cluster replacement, free of charge. There is no software fix; a dealer offering only a reflash has not performed the campaign. Verify eligibility by VIN at NHTSA.gov before scheduling, and if the cluster has already been replaced at owner expense, submit the receipt to Chrysler customer service (1-800-853-1403) for reimbursement under the recall.

Frequently asked questions
What does U0155 mean on a Jeep?
U0155 stands for "Lost Communication with Instrument Cluster." This is a network communication code meaning a control module (usually the engine or body computer) has lost communication with the instrument cluster over the vehicle's data bus. Modern vehicles share information between modules over a network (such as CAN), and the cluster both displays data and relays messages. When messages from the cluster stop arriving, this code sets. You may see warning lights, dead or erratic gauges, missing displays, or other modules acting up. It usually points to wiring, power/ground, or the cluster itself rather than the engine. On Jeep it is documented across 2 models: Gladiator, Wrangler.
What are the most common causes of U0155?
The most common causes of U0155 are: Faulty instrument cluster, Loss of power or ground to the cluster, Damaged or corroded CAN bus wiring, Loose or corroded connectors at the cluster, Blown fuse feeding the cluster, Short or open on the communication bus, A different failed module dragging down the bus. The specific cause varies by vehicle.
How much does it cost to fix U0155 on a Jeep?
Published repair estimates on Jeep range from $150 to $1,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
