There are 3 owner-reported brakes complaints for the 2023 Jeep Wagoneerin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Brakes completely went out, needed a brake module, received the vehicle back and the brake light is on
Leaks break fluid when parked at an angle (nose facing down hill). Heat seems to be a factor because it leaks more on hot days. The dealer has tried to remedy the problem no fewer than 4 times, replacing many major components. There appears to be a design flaw in the master cylinder area as that is where the brake fluid keeps leaking from. I have to imagine if you keep losing break fluid it is a safety issue and an environmental one.
This vehicle has a persistent brake fluid leaking problem. Anytime the vehicle is parked at a ~ 7% incline, where the front of the car is lower than the rear, the car leaks material amounts of brake fluid. The dealer has tried many times (over 4 times) to fix the issue by replacing all relevant parts… it still leaks. Based on my observations, there appears to be a design flaw in the brake fluid reservoir and the reservoir cap, it can not keep the fluid in the system. The risks arising from the persistent leaks include: 1.) catastrophic brake failure due to insufficient fluid in the system, 2.) fire risk, engine compartment has flammable brake fluid places it should not be, 3.) environmental contamination risk, and 4.) slip and fall risk from leaving slippery puddles of hazardous material ever place this vehicle is parked on an incline.
