Vehicle Specs & Maintenance Data
The 2022 Jeep Grand Cherokee L maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Jeep Grand Cherokee L.
For oil changes, the 2022 Jeep Grand Cherokee L takes 5W-20 Full Synthetic motor oil with a capacity of 5.9 quarts. Brake fluid type is DOT 3, the recommended coolant is Mopar OAT (Purple/Violet), and transmission fluid is ATF+4. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Jeep Grand Cherokee L, torque the lug nuts to 110 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.

Common problems reported by 2022 Jeep Grand Cherokee L owners, with recommended fixes and estimated repair costs.
Transmission Harsh Shifting and Hesitation
The 2022 Grand Cherokee L equipped with the ZF 8HP75 8-speed automatic transmission exhibits harsh shifts, particularly between 1st and 2nd gear, hesitation when accelerating from a stop, and occasional transmission shudder at highway speeds. Some owners report the transmission downshifting aggressively when light throttle is applied, causing an uncomfortable lurching sensation.
Reflash the Transmission Control Module (TCM) with the latest calibration software per TSB 21-019-22 REV. B. Perform a transmission adaptive learning reset. If shudder persists, a transmission fluid change with ZF-approved LifeGuard Fluid 8 is recommended. Some cases have required torque converter replacement under warranty.
Est. Cost: $0 - $2,500Uconnect 5 Infotainment System Failures
The Uconnect 5 infotainment system with the 10.1-inch touchscreen experiences frequent freezing, random reboots, black screen events, and wireless Apple CarPlay/Android Auto disconnections. The navigation system loses GPS signal intermittently, and the 360-degree surround view camera displays distorted or frozen images. These issues are present across multiple software versions.
Update the Uconnect 5 firmware to the latest version. TSB 08-058-22 REV. A covers radio reprogramming and reset procedures. Performing a hard reset by holding the volume and tune knobs simultaneously for 10 seconds can temporarily resolve freeze conditions. In persistent cases, the head unit requires replacement under warranty.
Est. Cost: $0 - $1,500Electrical System Glitches and Driver Assist Shutdowns
The 2022 Grand Cherokee L suffers from electrical system instability including random driver-assist feature shutdowns (adaptive cruise control, lane centering, forward collision warning), instrument cluster blackouts, and start-stop system malfunctions. The Intelligent Battery Sensor (IBS) frequently misreads charging state and triggers power management mode, disabling multiple systems.
Replace the Intelligent Battery Sensor and update the Body Control Module software. TSB 08-075-22 addresses IBS-related power management faults. A full 12V battery system reset (both terminals disconnected for 15 minutes) may also resolve communication glitches between modules. Update all module software to the latest calibration.
Est. Cost: $150 - $600Third-Row Seat and Cargo Area Build Quality Issues
The third-row seats are difficult to fold and unlatch, with the release mechanisms binding and requiring excessive force. The cargo area trim panels detach and rattle at highway speeds. Rear seat climate control vents blow inconsistently, and the third-row USB ports intermittently lose power. These are widespread quality control issues from early production builds.
Lubricate the third-row seat latch mechanism and cable with silicone spray. Resecure cargo trim panels with push-pin retainer clips per TSB 23-006-22. Reprogram the HVAC module for rear zone calibration. USB port failures typically require replacement of the rear power outlet module under warranty.
Est. Cost: $0 - $500Suspension Clunking and Premature Bushing Wear
The 2022 Grand Cherokee L develops a clunking noise from the front suspension when driving over bumps, potholes, or rough pavement at low speeds. The noise is traced to premature wear of the front stabilizer bar end links and control arm bushings. The air suspension system (on equipped models) also reports faults and fails to maintain ride height properly.
Replace the front stabilizer bar end links and inspect the control arm bushings. TSB 02-005-22 covers front suspension noise diagnosis for the WL platform. For air suspension models, the height sensors and air spring solenoid valves should be checked. Recalibrating the air suspension ride height sensors may resolve leveling faults.
