Ram Hurricane Engine Problems: Are They Serious?

The Ram Hurricane is a genuinely new engine, a twin-turbo 3.0L inline-six built largely from a clean sheet, replacing the HEMI V8 across most of Ram’s lineup since around 2023. As with any new platform, real issues have surfaced in its first few years, but the honest picture is more nuanced than either the enthusiastic praise or the alarming forum threads suggest on their own.

Ram Hurricane Engine Problems at a Glance

Two Versions, One Platform

The Hurricane comes in two states of tune: the standard version producing 420 horsepower and 469 lb-ft of torque, and the High Output version producing 540 horsepower and 521 lb-ft, both from the same twin-turbo 3.0L inline-six architecture. It replaced the naturally aspirated HEMI V8 (395 horsepower, 410 lb-ft in non-TRX form) across most of the Ram 1500 lineup, and also appears in the Jeep Wagoneer platform, which shares some of the same reported issues.

Thermostat Failures

This is one of the most consistently reported issues, with some owners noting failure as early as 10,000 miles. The thermostat regulates coolant flow to keep the engine in its correct operating temperature range, so a failure can push the engine to run abnormally cold or to overheat, either of which risks internal damage if left unaddressed. This is generally covered under warranty when caught, but it’s worth monitoring your temperature gauge specifically if you own an early-production Hurricane-equipped vehicle.

Turbo System Complexity and Reported Leaks

The Hurricane’s twin-turbo setup is genuinely complex, with four separate coolant and oil lines running to and from the turbochargers, plus an electronically controlled wastegate that depends on wiring and ECU signal interpretation rather than a simpler mechanical setup. More components and more electronic dependencies mean more potential failure points compared to a naturally aspirated engine, and this complexity has coincided with reports of turbo leaks in both Ram trucks and the related Jeep Wagoneer platform. This is a reasonable tradeoff most owners accept for the power and efficiency gains of a smaller, boosted engine, but it’s worth understanding going in rather than assuming a turbocharged inline-six behaves like the naturally aspirated V8 it replaced.

Software-Related Misfires

A number of owners report check engine lights with misfire codes that trace back to software issues rather than the spark plugs or ignition coils that would typically cause a misfire on an older engine. This is a pattern with genuinely new, heavily electronically-controlled engines: the fix is often a software update rather than a parts replacement, though it does mean a misfire code isn’t always the straightforward diagnosis it would be on a simpler engine.

The Honest Overall Picture

As of mid-2026, the National Highway Traffic Safety Administration has not issued a recall specific to the Hurricane 3.0L twin-turbo; Stellantis has instead addressed known issues through technical service bulletins and customer satisfaction programs, meaning fixes are generally covered but through a shorter, less publicized window than a formal recall. Independent reporting on ownership experiences generally describes this as a pattern of new-platform teething issues rather than evidence of a systemic design flaw, though it’s genuinely too early, with limited high-mileage examples on the road, to know how the engine performs over 100,000-plus miles. If you’re considering a Hurricane-equipped vehicle, checking your specific VIN through NHTSA’s recall lookup and asking directly about thermostat or turbo-related dealer visits during a test drive are reasonable, proportionate steps, not signs of a car to avoid entirely.

Frequently Asked Questions

Is the Ram Hurricane engine reliable?
The available evidence points to typical new-engine teething issues (thermostat failures, software-related misfires, turbo system complexity) rather than a documented systemic failure pattern. It’s genuinely too new to have a long-term, high-mileage track record yet.

What is the most common Ram Hurricane problem?
Thermostat failure is among the most frequently reported issues, in some cases surfacing by around 10,000 miles, followed by software-related misfire codes and reports of turbo system leaks.

Has the Ram Hurricane engine been recalled?
As of mid-2026, no NHTSA recall specific to the Hurricane 3.0L has been issued. Known issues have instead been addressed through technical service bulletins and manufacturer customer satisfaction programs.

Is the Hurricane engine better than the HEMI V8 it replaced?
It offers more power, more torque, and better efficiency from a smaller displacement, but it trades the HEMI’s mechanical simplicity for a more complex, electronically-dependent turbocharged system with its own new set of failure points.
