Sport Utility Vehicles continue to dominate roads across the United States due to their blend of performance, space, and practicality. As more drivers lean toward these vehicles for daily commutes, road trips, or family duties, the mechanical reliability of core components has become increasingly important.
One such component that often gets less attention than the engine or transmission is the steering rack. While not a flashy feature, the steering system plays a vital role in ensuring the vehicle responds precisely to the driver’s input. Its reliability can influence not just control and comfort but also long-term maintenance costs.
A common issue some SUV owners face involves the pinion seal, which helps prevent power steering fluid from leaking out of the rack. When that seal wears out or fails, fluid leakage can lead to poor steering performance, increased wear, and expensive repairs.
On the flip side, some SUVs are built with steering racks that remain sealed over long periods, giving owners peace of mind. This article takes a detailed look at two sides of this issue. First, we examine five SUVs known for their well-sealed steering racks that deliver long-term durability without consistent leaks.
Then, we highlight five models reported to suffer from pinion seal leaks more frequently, which may lead to increased maintenance and ownership concerns. Each vehicle is discussed individually with a focus on performance, build quality, driver experience, and steering system reliability.

SUVs with Leaky Pinion Seals
1. Jeep Grand Cherokee (Early WK and WK2 Models)
Jeep’s Grand Cherokee has earned praise for its performance, off-road ability, and premium feel, especially in the WK and WK2 generations. Yet, beneath its rugged appeal lies a recurring concern that many owners and mechanics have encountered the steering rack’s vulnerability to pinion seal leaks.
This issue tends to surface after several years of regular driving and becomes even more noticeable under harsh conditions or in warmer climates.
The Grand Cherokee uses a rack-and-pinion steering system with hydraulic assistance in many trims, before later models switched to electric steering. While the general system delivers confident road handling and decent steering feedback, the pinion seal has been a weak point.
When this seal begins to wear, fluid starts seeping from the connection point between the pinion gear and the steering rack housing. The leak might begin slowly, often going unnoticed until drivers hear groaning sounds during tight turns or find power steering fluid under the vehicle.
This leakage doesn’t just impact steering smoothness. As fluid levels drop, the power steering pump can overwork itself, creating additional strain and possibly leading to pump failure.
In the course of time, the system’s pressure can cause the leak to worsen, leading to increased repair costs. Replacing the rack or rebuilding the pinion section is often recommended when the leak becomes serious. For owners out of warranty, this repair may run into thousands, depending on the extent of damage.
Several owners have noted that even after replacing the rack, the same issue can resurface within a few years if the replacement unit doesn’t include improved sealing.
While Jeep has worked to resolve this in more recent models, earlier WK and WK2 variants from around 2005 through 2013 are particularly known for this issue.
Prospective buyers of used models should pay attention during test drives and have a mechanic inspect the area around the pinion seal. Those already owning the vehicle should monitor steering fluid levels frequently and address any changes in steering feel promptly.
2. Chevrolet Traverse (First Generation)
The first-generation Chevrolet Traverse offered space and practicality for large families, but its power steering system brought recurring headaches to many owners.
Among the most common issues was fluid leakage from the steering rack’s pinion seal, which could compromise the vehicle’s handling and make steering unpredictable in the long run.
Manufactured from 2009 through 2017, the early Traverse relied on a hydraulic power steering system that placed consistent pressure on its rack-and-pinion setup.
While the system delivered acceptable feedback when working properly, the quality of the pinion seal came into question as numerous reports of fluid leakage surfaced after just a few years of ownership.
The pinion seal, located where the steering column meets the rack, tends to degrade from heat exposure and pressure changes, especially in vehicles regularly driven in urban settings with constant turning and parking.
Owners often complained of a whining or moaning sound during low-speed maneuvers. This noise is usually the first indicator of declining fluid pressure due to leakage.
Ignoring the issue can result in stiff steering, reduced control at lower speeds, and eventual pump damage. In many instances, dealership technicians traced the issue back to a leaking rack, and the most effective fix was replacing the entire assembly rather than attempting temporary solutions.
Another concern was that the leaks would sometimes go undetected for months because of how the fluid dripped slowly and collected on underbody components.
Drivers may not find puddles under the car, yet the power steering reservoir continues to run low. Without proactive maintenance, this condition can affect steering performance and increase wear on tires and suspension due to misaligned input.
While newer models moved to electric power steering, the first-gen Traverse remains on the used market and continues to raise caution flags for those looking to purchase an older, budget-friendly SUV. Those who already own one should schedule regular steering inspections and consider preventive rack replacements if early symptoms emerge.
3. Ford Explorer (Fifth Generation)
The fifth-generation Ford Explorer, produced from 2011 through 2019, marked a change toward a more crossover-like design with enhanced comfort and technology.
While its stylish design and improved interior earned praise, many drivers experienced frustrations linked to the steering rack, particularly related to pinion seal issues that led to fluid leakage.
Equipped with a hydraulic rack-and-pinion system in several of its configurations, the Explorer offered solid on-road control. However, steering fluid leakage became a known concern for owners as mileage increased.
The pinion seal, which acts as a barrier between the pressurised fluid and the mechanical parts of the steering rack, is often the first to give way. When that happens, fluid slowly escapes and affects the steering performance, sometimes causing a jerky response or an audible strain from the steering pump.
Early signs are often subtle, reduced assist during tight turns, a faint buzzing sound when steering at low speeds, or the need to top up power steering fluid more frequently.
Left unchecked, the problem can escalate, with full rack replacement being the only lasting repair. Some mechanics attempted to reseal or replace the pinion seal alone, but the recurrence rate made rack replacement a more practical route.
This issue was not isolated to high-mileage vehicles. Several drivers reported leaks around the 50,000 to 70,000-mile mark, raising questions about the long-term durability of the rack.
Ford issued technical service bulletins addressing steering-related complaints, though no formal recall directly cited the pinion seal leakage in every affected case.
Buyers eyeing used Explorers from this generation should test the steering feel during turns and ask about any recent rack replacements. If purchasing from a dealer, request service records that include power steering system checks.
For current owners, scheduling steering inspections can help catch the problem early, especially if steering assist has become uneven or if fluid spots start to appear on the garage floor.
4. Hyundai Santa Fe (2013-2018 Models)
Hyundai’s third-generation Santa Fe provided an attractive package for buyers seeking a midsize SUV with a sleek design and generous features.
It was a popular choice due to its price point and equipment, but some units within the 2013 to 2018 range developed reliability concerns around the steering rack, particularly with pinion seal leaks that affected the entire steering performance.
The hydraulic power steering system on certain trims relies on pressure-sensitive seals to maintain steering fluid flow through the rack. After some time, the pinion seal tends to break down, especially under conditions involving heavy city driving, extreme heat, or prolonged idle steering, like during tight parking.
Once compromised, the seal allows fluid to escape, reducing system pressure and triggering signs of failure like stiff steering and high-pitched noises.
Santa Fe owners often notice fluid stains underneath the engine bay or hear the tell-tale whine when making sharp turns. The vehicle can still function during early leakage stages, but steering becomes less responsive. Fluid loss also places added strain on the pump and hoses, often requiring a full system flush and possible rack replacement if the problem goes unaddressed.
Some drivers delayed repairs due to the intermittent nature of the symptoms. However, with continued use, the fluid leak worsens, eventually making the SUV harder to control during slow turns or parking maneuvers. The cost of repair rises once the leak spreads to other steering components or causes the power steering pump to fail.
Although newer models now use electric steering, vehicles from this generation remain widely available in the used market. Anyone considering a 2013-2018 Santa Fe should pay close attention to steering feedback during a test drive and ask whether the rack has ever been replaced.
Those already owning one are advised to check fluid levels regularly and act quickly if signs of leakage or steering noise begin to surface.

5. Dodge Durango (2011-2017)
The Dodge Durango blends strong towing ability with a muscular road presence. While it checks many boxes for performance and space, several model years between 2011 and 2017 have shown a pattern of steering system concerns.
A frequent complaint from drivers during this period was leakage around the pinion seal of the rack-and-pinion system, often leading to a drop in steering fluid pressure and a decline in vehicle control.
This issue commonly arises after moderate mileage, though in some cases it has appeared before the 70,000-mile mark. The design of the Durango’s steering rack, combined with the placement of the seal close to heat-generating components, may contribute to faster wear and tear. Once the seal begins to wear out, steering fluid can seep out gradually, going unnoticed until signs of trouble begin to show.
Common symptoms include a gradual stiffening of the steering wheel, strange sounds during turns, and frequent topping off of the power steering fluid reservoir.
Some owners reported finding fluid near the front suspension or on the driveway. Because the power steering system relies on consistent fluid levels, any leakage weakens the assist mechanism and can make the Durango feel less agile during cornering or at low speeds.
Replacing the pinion seal by itself is rarely a long-term fix. Many repair professionals advise replacing the entire rack assembly to address internal wear that may have contributed to the initial leak.
The cost of this repair can vary, but it often runs into thousands when performed at a dealership. Dodge issued service guidance to technicians for identifying early-stage leaks, but no official recall was issued specifically for this issue.
Anyone owning or considering a 2011-2017 Durango should be alert to early signs of fluid loss, especially if the steering begins to feel inconsistent. Regular inspections and prompt attention to any leakage can help maintain vehicle safety and prevent costlier repairs down the road.
