2023 Jeep Wagoneer Reliability Report

Sudden shutdowns that throw the SUV into Park lead this mixed group, repeating patterns found in other categories. Also reported: a driver display that stays blank except for the start prompt, a transmission stuck in a low gear when accelerating, and thermostat failures that cause overheating and stranding. One report describes the panoramic sunroof shattering while the car was parked. Others describe disputes with dealers over open recall work at sale and recall work recorded as finished. The one crash-related filing involves road debris, not a vehicle defect.

Power steering cuts out without warning. The wheel stiffens or locks, and a "Power Steering Unavailable Service Required" or "Service Power Steering" message appears. The engine often shuts off at the same time. Reports describe this at stoplights, in parking lots, and at 80 mph on the interstate, where the driver could barely turn the wheel. Some owners also lose brake pedal feel. Repeat shop visits, dealers who find nothing wrong, and waits of up to six weeks for parts come up often.

The rearview mirror mount breaks away from the windshield during a normal adjustment and pulls glass out with it. Another report describes a visible warp in the windshield under the mirror that is bad enough to cause vertigo. A third describes a sun visor that drops down while driving and blocks the road. Owners say other Wagoneers have the same mirror and windshield problems and that no fix has been offered. Only three complaints fall here.

The main complaint is strong vibration at highway speed. It starts around 60 to 70 mph and gets worse the faster the car goes. The steering wheel shakes, passengers feel carsick, and owners say no fix exists. In a separate report, lug nuts came loose after a dealer tire rotation on a vehicle with aftermarket wheels and spacers, and the wheel could be moved by hand. That case involves aftermarket parts and dealer installation, not the factory wheels.

Most reports here are about a repair delay, not a failure. Owners were told about a rear quarter window trim repair, but the part was not available. Some stopped driving the vehicle while they waited, and one says the wait is hurting resale value. The one actual failure is a panoramic sunroof that shattered on the freeway at about 65 mph with no debris strike. The shade screen underneath kept the glass from falling on the occupants.

Brake fluid leaks from the master cylinder and reservoir area when the SUV is parked nose-down on a slope. The leak gets worse on hot days. Owners report more than four dealer visits, with major parts replaced, and the leak continues. They worry about losing braking and about flammable fluid in the engine bay. One separate report describes a complete brake failure that needed a new brake module. The brake warning light stayed on after that repair.

In a 55 mph crash into a guardrail, the front air bags did not deploy. The dealer said the sensor placement meant the system worked as designed, and the vehicle was not diagnosed or repaired. The second complaint describes a rattling noise while driving at about 30,000 miles, with no warning lights. That vehicle also went undiagnosed and unrepaired. With only two complaints, there is no clear pattern beyond the crash where the air bags did not deploy.
