Owners report several engine issues with the 2020 Jeep Gladiator, particularly involving the 3.6-liter Pentastar engine. A common problem is engine misfires, often accompanied by ticking noises, rough idling, and check engine lights, typically occurring around 1,000 to 75,000 miles. Complaints frequently mention coolant leaks leading to engine overheating, with some cases requiring cylinder head replacements. Additionally, an oil pump failure and camshaft lobe damage are noted, with one instance escalating to a fire due to a clutch issue. These issues potentially pose safety risks, such as sudden power loss while driving, which could be hazardous.

Owners of the 2020 Jeep Gladiator frequently report issues with the sun visors, which tend to detach from their mounts, obstructing the driver's view and creating a potential safety hazard. Complaints also highlight problems with the front windshield defroster, which inadequately clears the sides of the windshield, particularly during inclement weather, leading to visibility challenges. These issues are often noted in vehicles with low mileage, sometimes under 3,000 miles, and there are no reports of crashes directly linked to these failures, but the visibility problems could contribute to unsafe driving conditions. Additionally, some owners mention that windshield washer fluid fails to spray effectively at higher speeds, further impacting visibility.

Owners of the 2020 Jeep Gladiator frequently report issues with the sun visors, which can detach and obstruct the driver's view, potentially leading to hazardous situations while driving. Instrument panel failures are another common problem, leaving drivers without access to critical information like speed and fuel levels. Additionally, multiple complaints describe sudden electrical malfunctions that result in loss of power steering and inability to control or shut off the vehicle, often at highway speeds. These issues appear across a range of mileages, with some incidents occurring in vehicles with less than 3,000 miles. Safety implications include one reported crash and an injury due to a door mechanism, highlighting potential risks for prospective buyers.

Owners of the 2020 Jeep Gladiator frequently report issues with the vehicle's suspension, particularly noting a "death wobble" where the front wheels violently shake and vibrate, often after encountering bumps or variations in the road surface.

Several owners describe a lack of control and difficulty steering, which they associate with potential safety risks. Additionally, complaints mention problems with rear control arm welds breaking and shock bracket welds failing, leading to hazardous handling conditions and potential tire damage. These patterns suggest that prospective buyers should be aware of these recurring suspension-related issues and their implications for vehicle stability and safety.

Owners of the 2020 Jeep Gladiator frequently report structural issues primarily related to the vehicle's roof and doors. Complaints often describe problems with the soft top detaching or unsecuring while driving, which can occur at highway speeds and pose a risk of loss of control or damage to other vehicles. Several reports highlight water leaks from the roof, particularly at the rear window and center front, sometimes causing water to hit the driver unexpectedly. Additionally, some owners note a clicking sound from the doors due to the aluminum exterior peeling away from the steel structure. These issues have been reported at various mileages, with some occurring as early as 67,000 miles, and may involve significant out-of-pocket repair costs as they are not covered by warranty.
