Owners have filed 45 brakes complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Buyer takeaway: A used 2018 Grand Cherokee with brake complaints carries serious risk: many vehicles are subject to recalls (24V838000, 22V426000) with unavailable parts, leaving the brake system unsafe and potentially immobilized. Get a full brake inspection and confirm all recalls have been completed with parts currently in stock before purchase.
The 2018 Grand Cherokee brake complaints reveal a dominant pattern: widespread failure of the hydraulic control unit (HCU) and ABS system, with repair parts unavailable since recall campaigns 24V838000 and 22V426000 were announced. Owners consistently report that dealers confirm the HCU is faulty but cannot obtain replacement parts, leaving vehicles unsafe and immobilized—some parked since 2024. Warning lights include brake, ABS, traction control, and electronic stability control.
Beyond the parts shortage, owners report acute braking failures: complete loss of brake pressure with pedal sinking to the floor, uncontrolled acceleration when shifting or removing foot from brake, and vehicles rolling backward or forward while parked in Drive or Park. One owner's vehicle ran over his legs after rolling at an airport curb. Low-speed loss of control and collision damage are documented.
A secondary safety gap: Adaptive Cruise Control applies brakes automatically without illuminating brake lights, creating rear-end collision risk. Forward Collision Warning and Active Stop systems have also malfunctioned, accelerating instead of braking in at least two incidents.
Rear brake systems have failed silently, with frozen calipers and complete pad wear by 28,000 miles. Brake lights remain illuminated when the engine is off, and even recall repairs for this issue have failed to hold.
Owners report dealerships unable or unwilling to help, lack of rental assistance during downtime, and manufacturer responses ranging from form letters claiming no defect to silence.

Recalls/TSBs owners mention: NHTSA Campaign 24V838000 and 22V426000 issued; parts on backorder with no announced availability. Manufacturer referred owners to dealers, provided form letters stating no defect found, and in some cases opened cases without resolution. Parts unavailable as of mid-2025 per multiple owner reports.
Brake Pedal and Brake System Failure—Total Loss of Braking
Complete or near-complete loss of braking ability while driving, with brake pedal sinking to the floor or becoming unresponsive. Owners unable to stop vehicle at red lights, during traffic, or in emergency situations, resulting in collisions and accidents.
When: 1,400 miles; 3,700 miles; 35–45 mph incidents; one report at 33 mph in city traffic
Symptoms owners cite: Brake pedal depresses fully to floor with no resistance; Complete inability to stop vehicle; Brakes fail to engage when applied; Partial brake engagement only; Brake failure during bumper-to-bumper traffic; Brakes fail to respond while reversing; Extended stopping distance
Repairs/costs cited: Collision damage reported: $1,100 front-end damage in one case. Owner in complaint #2 paid out of pocket; engineer inspection claimed no defect found. No manufacturer-authorized repairs documented; vehicles deemed unsafe by dealers.
Recalls/TSBs owners mention: No assistance offered in cases where brakes completely failed. In complaint #2, manufacturer sent form letter stating no defect found and declined to provide rental assistance.
Unintended Acceleration / Loss of Throttle Control
Engine races forward, vehicle accelerates uncontrollably despite brake pedal being applied. Occurs when shifting into Drive or during normal low-speed maneuvering. Distinct from brake failure—engine roars and wheels spin.
When: 3,700 miles (complaint #1); 31,000 miles (complaint #7, parking lot at 1 mph); low-speed incidents
Symptoms owners cite: Engine roars and races forward uncontrollably; Vehicle accelerates despite foot on brake pedal; Vehicle lunges forward suddenly when brake released; Vehicle accelerates forward when shifting from Reverse to Drive; Wheels spin when vehicle should not be moving
Repairs/costs cited: Complaint #1 resulted in total loss—vehicle steered into backstop wall, front and side airbags deployed. No repair documented.
Recalls/TSBs owners mention: Complaint #1 escalated to Chrysler Customer Care (case number 33880270); vehicle deemed total loss by insurer (AAA). No root cause or repair solution provided.
Gear Shift Lock Failure—Vehicle Rolls in Park
Vehicle rolls backward or forward while parked and in Park position, or gear shifter moves out of Park without depressing brake pedal. Vehicle can move on its own when the driver exits or shifts.Related to brake interlock system failure.
When: 38,000 miles; 76,000 miles; multiple incidents on slopes or driveways
Symptoms owners cite: Vehicle rolls backward down driveway after being parked and engine shut off; Vehicle rolls forward in parking lot into concrete block; Gear shifter can be moved out of Park without depressing brake pedal; Vehicle starts without brake pedal depressed; Vehicle can shift out of Park with engine running
Codes mentioned: 24V838000
