RAM Hurricane Engine Problems

Common RAM Hurricane engine problems include cooling system issues such as thermostat failure, check engine light issues, and damaged catalytic converters. In several 2025 Ram trucks, excessive exhaust gas temperatures from misfires can damage the catalytic converter.

The engine is available in two versions: Hurricane - 420 hp, 469 lb‑ft; High Output - 540 hp, 521 lb‑ft. By comparison, the non‑TRX HEMI makes 395 hp and 410 lb‑ft.

This blog covers the most common RAM Hurricane engine problems, performance details, and what to expect in long-term ownership.

What Is the RAM Hurricane Engine?

The Hurricane motor is Stellantis's twin-turbocharged 3.0-liter inline-six. In 2024, it began replacing the HEMI V8 for 2025 models. The engine architecture is a big deal because most of the early problems trace back to it. Ram's twin-turbo truck engine is the 3.0-liter Hurricane inline-six, not a V6. Its most common problems are cooling-system faults such as thermostat failure, check engine light misfire codes, and catalytic converter damage.

Inline-six engines with twin turbochargers generate more power with less displacement. That means they have higher boost levels and a much more complex arrangement of sensors, software, and cooling systems compared to the HEMI's simpler V8 design.

Under normal conditions the Hurricane runs on regular 87 octane fuel but according to the manufacturer, you should use premium fuel with an octane level of 91 or higher for towing, heavy loads or in hot weather, especially if you have the High Output version.

According to aggregated NHTSA complaint data for the 2025 Ram 1500 platform, owners have filed numerous complaints, mostly within the first few thousand miles.

Before you start troubleshooting with a dealer, there are two things worth knowing. First, the Hurricane uses an electronic oil-level sensor, so owners check the oil level on the dashboard display.

Second, both Hurricane variants are turbocharged, so turbo maintenance matters more than with the HEMI. After hard driving or towing, let the engine idle briefly so the turbo bearings cool while the oil is still flowing.

Compared with Ford's twin-turbo V6 lineup, the difference is not about more power but about calibration and early-build consistency.

Both platforms rely heavily on tuning of boost control and software, but reports from owners indicate that Ford's systems have had a slightly longer refinement period in the field. The Hurricane emphasizes compactness and high output along with good fuel economy; however, some new components needed fixes in early builds.

What Are the Most Common Problems With the RAM Hurricane Engine?

Owners report recurring issues related to the Hurricane engine that have been confirmed by Stellantis service bulletins. We also need to distinguish these recurring issues from formal safety recalls. At present there are no specific major recalls just for the Hurricane engine itself.

Cooling-system faults are among the best-documented concerns. The Hurricane's rotary ball‑valve thermostat is operated by a plastic arm powered by a wax‑pellet motor.

Plastic thermostats can malfunction if they're repeatedly heated and cooled. They can stick shut and cause overheating of the engine. This can be really annoying for people who recently bought a new truck because when these symptoms show up, the truck may have very low mileage.

Repair complexity adds to the concern. Unlike most older vehicles with Chrysler and RAM engines, the Hurricane's thermostat is under the twin turbos and behind multiple coolant and oil components. That means replacing it is more complicated and labor intensive.

Dealers such as Mark Dodge found assembly-quality issues. In our experience, these problems can create coolant leaks that mimic more serious failures.

Owners should also watch for catalytic converter damage caused by misfires, which can happen after an ignition or fuel-system fault that triggers a P0300-series misfire code. Unburned fuel could end up entering the exhaust and igniting inside catalytic converters.

High temperatures that result from this process can turn what might be a minor fix into an expensive replacement job. That's why techs tend to suggest addressing warning lights promptly when they show up.

In addition to cooling issues, some owners have reported that there are also minor electrical faults such as sensor problems, warnings and intermittent fault codes. Currently these reports are scattered rather than indicating a widespread problem; most Hurricane trucks don't require major electrical repairs.

As with many new vehicles, online forums tend to amplify problems because satisfied owners are less likely to post than someone experiencing a failure.

A new member who joins a discussion forum on RAMs might think that this is an issue affecting everyone, but recent longer term reports indicate that it affects only a small part of the fleet as a whole.

Prospective buyers should note that the Hurricane has a reputation for high performance, but early-production cooling components and quick responses to misfire codes deserve attention.

If these concerns are addressed quickly, most owners say their trucks operate well and retain expected power and refinement.

Why Does the Hurricane Engine Cause Misfires and Check‑Engine Lights?

Owners frequently report having trouble with their check engine lights coming on and codes indicating misfires. Most of those issues don't relate to spark plugs or coils. The usual cause is a software calibration issue in the ignition system control module, which Stellantis addressed with two technical service bulletins.

TSB 08-055-25 targets High Output Hurricane models built on or before January 7, 2025, and requires reprogramming the ISCM to fix hesitation and misfire codes.

Standard Output Hurricane models built on or before October 4, 2024, are covered under TSB 08-031-25, which has since been superseded. Confirm the current bulletin number with the dealer. A separate service bulletin has addressed misfire codes traced to oxygen sensors.

When you see a P0300-series code appear there are two practical things that owners should do. Check the sticker on the driver side door jamb for the build date. The date is printed alongside GVWR (gross vehicle weight rating) as the month and year.

If your build date is within the TSB window period, go straight to the service department and ask specifically about bulletin 08-031-25 or 08-055-25. Most of these problems can be fixed with a no-cost reprogram as part of this bulletin and having the bulletin number ready shortens diagnosis time.

What Is the Recommended Procedure to Take Care of the RAM Hurricane Engine?

Hurricane-specific maintenance poses special challenges which longtime owners of Rams equipped with HEMI engines aren't used to. Following the maintenance schedule in the owner's manual is the right place to start. Some points below require extra attention as they differ from HEMI maintenance and are sometimes forgotten.

Replacing spark plugs about every 60,000 miles and inspecting PCV valves around 100,000 miles is good maintenance practice. Follow the maintenance schedule in your owner's manual and also pay attention to the oil life indicator.

Use the oil type specified in your owner's manual. The Hurricane is a high-output boosted engine; using low-quality oil or extending oil change intervals can cause costly issues.

Cooling-system care is where the Hurricane platform demands more attention than the engine it replaced. Each time you change the oil, check the coolant level too. Watch for any sign of leakage at the thermostat housing, hose connections, or turbo drain. And respond quickly if your car issues a temperature warning.

One really important turbo care habit is to cool down after hard driving. Ideally, wait 1-2 minutes before turning off the engine to allow the turbo to cool down. Turbo specialists often suggest waiting up to two minutes. Owners should also inspect for disconnected air intake lines and any leaks in the turbo oil system to catch any issues early.

How Do You Maintain the Fuel System?

For regular driving, the Hurricane runs fine on 87 octane. But if you're towing, hauling, driving in hot weather, or using the High Output model, you should use premium fuel of 91 octane or higher. This will help boost performance and reduce pre-ignition. If you notice rough idling or misfires, fix this promptly. Those are early signs that there might be issues with the fuel system or sensors on your Hurricane.

What Have Owners Reported About the RAM Hurricane Engine?

Hurricane owner reports have been mixed in the first two model years of the engine's life. This section is meant to summarize what is already in the public record and not to repeat fabricated testimonials.

The Drive tested a 2025 Ram 1500 rental fleet truck for about 50,000 miles over one year; despite heavy towing and severe use, the Hurricane came through without catastrophic failure.

That data point is worth knowing because it indicates the basic engine architecture can hold up under hard miles.

Reports from other owners have been less favorable. Different evaluations concluded that the early rollout of the Hurricane has been rocky. Most of the documented problems have centered on support systems and not on the core engine itself.

Based on our experience, those Hurricane owners who avoid the biggest conflicts tend to see the first time they get a recurring check engine light as important data rather than just as an annoyance. At every service visit, record the date, mileage, trouble codes, and technician names, and take a photo of the dashboard.

How Have Owners Resolved Hurricane Engine Issues?

Most Hurricane issues are resolved through a Stellantis-authorized dealer using software updates, TSB-driven reprogramming, or replacement of faulty components such as thermostats and wiring.

Although owners debate long‑term reliability, most trucks are repaired under warranty. The cases that most often become a Dodge Ram lemon law claim are those involving repeated dealer visits for the same software-related problem without a lasting fix.

What Recalls Have Been Issued for the RAM Hurricane Engine?

At this point in time we don't know about any specific recalls issued by NHTSA related to the Hurricane 3.0-L twin turbo. Check the latest status at NHTSA's recall lookup.

The manufacturer uses service bulletins and customer satisfaction programs instead of issuing recalls and therefore repairs are covered under warranty and the free repair window is shorter.

How Do You Check for Hurricane-Related Recalls?

To check for Hurricane-related recalls, enter your truck's 17-character VIN into NHTSA's recall lookup and review both specific active recalls and any broader 2025-2026 campaigns. If you own a 2026 Ram 1500, enter your VIN into NHTSA's recall lookup, which covers 2025-2026 campaigns.

You can also register your VIN on the Mopar Owner's Companion app and get recall alerts directly so that you have reliable notifications and added reassurance after your purchase or test drive.

What Should You Do If Your Hurricane-Equipped Truck Has a Persistent Defect?

If a Hurricane engine problem persists despite multiple dealer repairs, recurring misfires, or overheating, it may require more than standard warranty service. The federal Magnuson-Moss Warranty Act and state lemon laws can provide relief when a manufacturer fails to fix a covered defect.

Many state lemon laws create a presumption in your favor after a reasonable number of repair attempts or around 30 cumulative days out of service within the state's eligibility period. Also, keep every repair order and check TSBs 08-055-25 and 08-031-25 against your VIN before paying for diagnostics.

While many Hurricane-equipped trucks deliver the fuel economy and performance buyers expect from the brand, repeated unresolved repairs can make a significant difference in your legal options.

Our Ram truck recall and lemon law rights page covers the next steps, and the Ram warranty breach lawsuit framework is the right reference if the manufacturer has not honored its written warranty.

Need a Lemon Law Attorney?

The Hurricane is a new engine in a high-volume truck and most reported problems seem to relate to auxiliary systems and software rather than the core engine functionality itself.

Many owners report strong highway performance, smooth power delivery, and better fuel economy than expected for a full-size truck. Drivers who haven't had repeated warning lights or cooling issues speak highly of the Hurricane's responsiveness when loads are heavy.

If your Hurricane-equipped truck has been at the dealer multiple times for the same defect and the problem keeps returning, our Lemon Law attorneys can assess your case. You can reach out to our team or contact us today to get started.

Frequently Asked Questions

Here are some common questions people often ask about the Hurricane Ram 1500 and their answers.

What Are Common Engine Problems Associated With RAM Hurricane Engines?

Among the most common complaints are cooling system issues: thermostat malfunctions and poor connections of hoses and clamps; check engine P0300 codes are often traced to ISCM calibration as well as other electrical problems. Early engines sometimes suffer damage to catalytic converters due to very high exhaust temperatures.

What Can I Do to Prevent Engine Problems?

Follow the maintenance schedule in the owner's manual; use fuel with at least 91 octane if you're towing or driving in very hot weather. Also, let your engine idle for a short time after hard driving to help protect the turbos.

Pay attention immediately to any check engine light or temperature warnings that show up, even if the truck seems fine. Save copies of every repair order from dealerships because that paper trail is very important for warranty claims or lemon law disputes.

What Should I Do If My RAM Hurricane Engine Is Overheating?

If you see an overheating warning, stop safely and let the engine cool down completely first. If it's safe to do so, check coolant levels and look at the thermostat housing and hoses for any signs of leakage. Since thermostats often fail, get your truck checked by a Stellantis-authorized dealer before you drive it again.

How Do I Address Oil Leaks in a RAM Hurricane Engine?

If you see any oil leak, make sure a qualified technician finds where the leak is before approving the repair work. Common Hurricane issues involve minor drips from a turbo drain seal or leaking gaskets and these need to be reassembled.

Because the engine uses an electronic sensor for oil level rather than a dipstick, investigate unexpected low-oil alerts. These could mean real oil loss, not just a sensor error.

What Are the Signs of a Misfiring RAM Hurricane Engine?

Most misfires trigger a check engine light (P0300). You may also notice rough idling, hesitation when accelerating, loss of power, or odd noises.

Many common issues on early-build engines seem related to ISCM software calibration and are addressed in service bulletins from Stellantis. Have the dealer check your VIN to see if you fall under TSB 08-055-25 or TSB 08-031-25 before spending money on diagnostics.
