2022 Jeep Grand Cherokee Reliability Report

Automatic emergency braking slams the SUV to a stop with nothing ahead, including in the middle of intersections and on empty roads. Following drivers have had to swerve to avoid a rear-end hit. A second pattern is a forward collision warning off light that appears along with the Italian-language, metric-unit display glitch. Dealer resets, sometimes billed to the owner, fix it only briefly. A few owners report the system failing to detect a car ahead and not braking at all.

Rear lower control arms fracture, a control arm bracket fails, and a tension link bolt snaps, sometimes at highway speed. In one crash with an injury, the wheel assembly came off at 67 mph. Many filings concern the rear coil spring recall, which covers springs that may detach, with dealers reporting parts unavailable for long periods. Front clunking and knocking over bumps also show up, often after the suspension warms up. Leaking struts and worn ball joints and bushings round out the reports.

Hybrid models shut off without warning, including on busy interstates at about 70 mph, and one stall led to a rear-end crash. Others lose power, stall, or will not start after charging-system and hybrid warnings. A separate pattern is a thumping or knocking from failing engine mounts that often appears only after about 30 miles of driving, which makes it hard for dealers to reproduce. Isolated reports cover a water pump leak, worn camshafts causing misfires, and a failed coolant pump.

Emergency braking engages hard at highway speed with no traffic ahead, locking seat belts and nearly causing rear-end crashes. Two crash reports describe the brake pedal not responding while parking, one ending in a building and one in a pole. Owners also report ABS, traction control, and brake booster faults after routine rear brake service done in service mode. Adaptive cruise and automatic braking warnings come and go for months without a lasting dealer fix.

Sudden loss of propulsion on the 4xe dominates these reports. A hybrid service warning flashes, the accelerator stops working, and the SUV may coast, go into park, and set the parking brake, sometimes on highways at 65 mph. Owners link it to recall 25V576, a hybrid control software error, and code B273C-00. Other complaints cover a fuel gauge that reads full until about 4 gallons are used, highway stalls blamed on a fuel pump, and the unresolved battery fire recall.

Unintended acceleration in driveways and garages appears in both crash reports, with the engine revving hard in drive or reverse. Adaptive cruise brakes violently when passing large trucks, and dealers have failed to fix it. One owner reports the set speed keeps climbing after the +/- button is released. Front camera faults shut off cruise, lane keeping, and automatic braking, starting at low mileage. Hybrid models also lose power at highway speed or fail to accelerate in electric mode.

Serious frontal crashes, including head-on and T-bone impacts, end with no deployment in all three crash reports, which include three injuries. Other complaints describe a warning light traced to a failing steering control module, a front passenger seat air bag deploying while parked, and a driver seat air bag inflating inside the upholstery and leaving a large bulge. Some owners of hybrid models also see air bag system warnings alongside power-loss and hybrid system warnings.
