The Hurricane engine is Stellantis' new 3.0-liter inline-six , which largely, replaces high-output V8 engines , like the 5.7- and 6.4-liter Hemi engines that have been driving Ram, Challenger, and Charger vehicles for several years now.
Although the new Hurricane inline-four engine has faced considerable backlash — primarily from devoted fans convinced that nothing less than a V8 can power a true muscle car — the motor appears to hold significant promise. The standard output version delivers robust performance with 420 horsepower and 469 pound-feet of torque, whereas selecting the high-output variant boosts these figures to an impressive 540 horsepower and 512 pound-feet of torque.
The twin-turbocharged, inline-six Hurricane isn’t just potent; it’s also significantly more fuel-efficient compared to the engines it supersedes. Additionally, Stellantis designed this engine keeping electrification in focus. Therefore, the outlook is promising, as greater power and enhanced efficiency lie ahead for Stellantis vehicles.

The Hurricane Engine Made Its Debut in the 2023 Jeep Models.
In late 2022, Stellantis introduced the Hurricane inline-six engine, which began appearing in production vehicles on dealer lots in 2023. The specific model equipped with this engine was theصند Jeep Wagoneer and the Jeep Grand Wagoneer, both of which debuted as 2023 models featuring the Hurricane engine beneath their hood.
Ever since their release, car owners have inevitably accumulated mileage on these vehicles, leading to a minor array of problems starting to surface. Automotive manufacturers can conduct extensive research and development prior to unveiling a new vehicle or engine design; however, genuine assessments of dependability and resilience emerge once everyday driving situations subject these models to practical use by their owners.
Therefore, it’s normal for problems to arise—not because achieving an entirely flawless and trouble-free engine is typically unattainable, but simply because perfection in engineering is hard to come by. Additionally, initial versions and debut-year models of vehicles and their engines often present more challenges. This is largely because these early editions haven’t undergone extensive testing under various real-world conditions yet. As difficulties surface over time, companies like Stellantis may then address them through improvements implemented in subsequent model years.
The 2023 model year Jeep vehicles are no different when it comes to this rule, and proprietors have reported problems with their Hurricane-equipped SUVs to illustrate this fact.
Owners Are Starting To Identify Frequent Problems With The Hurricane Engine
Several owners on the Jeep Wagoneer forum have posted about their experiences, with some reporting multiple frustrating and disconcerting problems with their Hurricane-equipped SUVs.
Misfire codes, oil-level warning lights, and even failed engines under 20,000 miles have been reported, but, on the whole, most owners seem impressed by the inline-six's refinement and power delivery. Another owner over on Reddit mirrors these sentiments, stating, "So far, the engine is robust. I've put around 40,000 miles on it and haven't experienced any problems."
However, one issue in particular is rearing its ugly head repeatedly -- a sticking thermostat -- which causes the Hurricane's temperature to rocket sky-high when driving. According to some owners, it's a quick and easy fix, while others are being told that it's a nationwide issue, and getting hold of the replacement parts is tricky, with mainly dealers struggling due to backorders.
Several significant recalls related to 2023 and subsequent Jeep Wagoneer models are still pending; however, none pertain specifically to the Hurricane engine. Overall, this suggests that the upgraded inline-six appears to be a dependable and credible substitute for the traditional Hemi V8 engines that Fiat Chrysler Automobiles (now Stellantis) had utilized extensively over the years.
