2023 Jeep Gladiator Reliability Report

Owners report a recurring issue with the 2023 Jeep Gladiator's suspension, specifically a violent vibration, often referred to as "death wobble," when encountering road irregularities at highway speeds. Typical symptoms include severe shuddering of the front wheels and steering wheel, which persists until the vehicle is decelerated significantly. Complaints frequently mention this issue arising at mileages as low as 610 miles, with occurrences noted up to 40,000 miles. This condition leads to concerns about potential loss of control, as owners describe needing to rapidly reduce speed to regain stability. Buyers should be aware of this behavior, as it is reported even in vehicles with low mileage and may pose a safety risk if not addressed.

Owners report issues with the powertrain of the 2023 Jeep Gladiator, particularly concerning the vehicle entering limp mode and losing power. Complaints frequently mention warning messages related to the clutch overheating and the check engine light illuminating, often accompanied by a sudden decrease in speed, which poses safety risks on highways. The problems are noted at various mileages, with one owner experiencing issues at approximately 15,000 miles. Some owners describe difficulties obtaining necessary recall repairs due to parts unavailability, with one complaint indicating unresolved defects following a previous recall repair. These issues suggest potential safety implications, particularly when driving at high speeds or on steep grades.

Owners of the 2023 Jeep Gladiator report issues primarily related to overheating relays and water intrusion. One complaint describes a vehicle fire occurring while the vehicle was parked and turned off, leading to total loss, indicating a significant safety concern. Another complaint from a repair shop notes that several Gladiators have relays in the under-hood fuse panel that appear to have been hot or overheating, though the cause remains undetermined. Additionally, an owner reports inadequate door sealing, resulting in water spraying into the cabin during car washes, raising concerns about potential water intrusion during rain. These issues are observed early in the vehicle's life, as indicated by the context of a "brand new truck."

Owners of the 2023 Jeep Gladiator report several issues with the service brakes. A common problem involves the parking brake becoming unattached, particularly concerning for manual transmission models where it is essential to prevent the vehicle from rolling. Another issue involves a "hissing" sound from the steering area during startup, which coincides with the vehicle moving unexpectedly despite the brake pedal being pressed; this problem has been noted around 6,162 miles and persists despite initial repairs. Additionally, at approximately 5,700 miles, an owner describes a rear brake caliper bolt falling out, causing damage to the wheel and preventing the vehicle from moving backward. These complaints highlight potential safety risks, including unintended vehicle movement and compromised braking ability.
