Owners often praise the Gladiator’s off-road capability, open-air driving experience, and distinctive styling. Common complaints revolve around its ride quality, fuel economy, and some reported reliability concerns.
Engine
3.6L Pentastar V6
- Excessive Oil Consumption
- Description/Symptoms: Some owners have reported higher-than-normal oil consumption, requiring frequent topping off between oil changes. This may manifest as blue smoke from the exhaust, particularly on startup.
- Solution: Monitor oil levels regularly. If consumption is excessive (more than 1 quart per 1,000 miles), investigate potential causes such as PCV valve failure, valve stem seal leaks, or piston ring issues. A compression test and leak-down test can help diagnose the problem. Replacement of the affected components will be necessary.
- Estimated Cost to Fix: $50 (PCV Valve), $1,000 - $4,000+ (Major Engine Work/Replacement)
- Recalls: None Found
- Tick/Rattling Noise
- Description/Symptoms: A ticking or rattling noise, typically emanating from the top of the engine, especially at start-up. This may be related to the rocker arms or lifters.
- Solution: Diagnose the source of the noise by inspecting the rocker arms, lifters, and valve train components. Replacement of the affected components may be necessary.
- Estimated Cost to Fix: $200 - $1,500+
- Recalls: None Found
3.0L EcoDiesel V6
- Engine Oil Dilution
- Description/Symptoms: Fuel can contaminate the engine oil, thinning it and reducing its lubricating properties. This issue is often linked to the diesel particulate filter (DPF) regeneration process where excess fuel is injected into the cylinders. Symptoms include rising oil level on the dipstick, fuel smell in the oil, and potential engine damage.
- Solution: Frequent oil changes using the correct oil specification are critical. Consider monitoring oil analysis to track fuel dilution levels. Software updates to the engine control unit (ECU) may help optimize DPF regeneration. In severe cases, a new diesel particulate filter may be needed.
- Estimated Cost to Fix: $100 (Oil Change), $500+ (DPF Replacement)
- Recalls: None Found
- Fuel Injector Issues
- Description/Symptoms: Rough idling, misfires, decreased fuel economy, and potential black smoke from the exhaust.
- Solution: Diagnosis involves scanning for trouble codes, checking injector pulse width, and performing injector balance tests. Replacement of faulty injectors is required.
- Estimated Cost to Fix: $400 - $1,200+
- Recalls: None Found
Transmission
8-Speed Automatic (850RE)
- Harsh Shifting/Hesitation
- Description/Symptoms: Abrupt or jerky shifts, particularly between certain gears. Hesitation when accelerating or shifting into gear.
- Solution: Start by checking the transmission fluid level and condition. A transmission fluid flush and filter replacement may resolve minor issues. If the problem persists, diagnose potential issues with the valve body, solenoids, or internal transmission components. Software updates to the transmission control module (TCM) may also address shifting problems.
- Estimated Cost to Fix: $200 - $500 (Fluid Flush), $800 - $3,000+ (Valve Body/Solenoid Replacement or Transmission Rebuild)
- Recalls: None Found
- Transmission Failure
- Description/Symptoms: Complete loss of drive, grinding noises, or inability to shift.
- Solution: Involves a thorough inspection to determine the extent of the damage. Depending on the severity, the transmission may need to be rebuilt or replaced.
- Estimated Cost to Fix: $3,000 - $7,000+ (Rebuild/Replacement)
- Recalls: None Found
Suspension
- Death Wobble
- Description/Symptoms: Violent shaking of the front end, particularly at highway speeds after hitting a bump or imperfection in the road.
- Solution: Death wobble is often caused by worn or loose steering and suspension components, including tie rod ends, ball joints, track bar, steering stabilizer, and wheel bearings. Inspect and replace any worn or damaged components. Ensure proper torque on all fasteners. A steering stabilizer upgrade may help dampen vibrations.
- Estimated Cost to Fix: $100 (Steering Stabilizer) - $1,500+ (Component Replacement)
- Recalls: None Found
Electrical
- Uconnect System Issues
- Description/Symptoms: Freezing, lagging, or crashing of the Uconnect infotainment system. Bluetooth connectivity problems.
- Solution: Try a hard reset of the Uconnect system. Ensure the system is running the latest software version. If the problem persists, the Uconnect module may need to be replaced.
- Estimated Cost to Fix: $0 (Software Update/Reset), $500 - $1,500+ (Module Replacement)
- Recalls: Recall Number: 21C12 - Uconnect Radio Software
- Description: This recall involves certain Uconnect radios. The radio software may cause the display screen to remain black after the vehicle is started, affecting the rearview camera image display.
- Solution: Dealers will update the radio software free of charge.
- Sensor Malfunctions
- Description/Symptoms: Various warning lights on the dashboard related to systems like ABS, traction control, or tire pressure monitoring (TPMS).
- Solution: Scan the vehicle’s computer for trouble codes to identify the faulty sensor. Replace the sensor as needed.
- Estimated Cost to Fix: $100 - $500+
- Recalls: None Found
- Battery Issues
- Description/Symptoms: Premature battery failure, difficulty starting, or electrical system malfunctions.
- Solution: Test the battery and charging system. If the battery is failing, replace it with a high-quality replacement. Inspect the battery terminals and connections for corrosion.
- Estimated Cost to Fix: $150 - $300+ (Battery Replacement)
- Recalls: None Found
Exterior
- Roof Leaks (Hardtop)
- Description/Symptoms: Water leaks around the seams of the hardtop, particularly during heavy rain or car washes.
- Solution: Inspect the weather stripping and seals around the hardtop panels. Replace any damaged or worn seals. Ensure the hardtop panels are properly aligned and secured.
- Estimated Cost to Fix: $50 - $300+
- Recalls: None Found
Interior
- Rattles and Squeaks
- Description/Symptoms: Various rattles and squeaks emanating from the dashboard, doors, or other interior trim pieces.

Summary
The 2020 Jeep Gladiator, while praised for its off-road prowess and unique design, does present some potential reliability concerns. The severity and cost of these issues vary. Engine problems, particularly oil consumption in the 3.6L V6 and oil dilution in the 3.0L EcoDiesel, can be expensive to address. Transmission issues can also be costly. Electrical glitches and suspension problems are more common but generally less expensive to repair. Prospective buyers should be aware of these potential issues and have the vehicle thoroughly inspected before purchase.
