Is the RAM ProMaster a reliable vehicle?

The RAM ProMaster can be a reliable work van with regular maintenance, but reliability is mixed compared with rivals and varies by year and configuration.

This article examines what reliability means for a cargo van, how the ProMaster has performed across generations, and practical steps owners can take to maximize uptime and minimize downtime.

What reliability means for a cargo van

In the context of commercial vans, reliability is measured by uptime, maintenance costs, frequency of unexpected repairs, parts availability, and how well the vehicle holds up under heavy use. Fleet and owner reviews, manufacturer recalls, and industry testing help paint a broader picture, but real-world results depend on mileage, payload, climate, and maintenance discipline.

Reliability overview: RAM ProMaster generations

The ProMaster introduced a front-wheel-drive, van-based design derived from the European Fiat Ducato, aimed at maximized cargo space and versatile configurations. Over its production span, there have been reports of varying reliability by model year and usage, with fleets frequently prioritizing service history and preventive maintenance. While some owners report years of productive service, others note electrical glitches, drivetrain concerns, or diesel-related maintenance in higher-mileage examples.

Common issues reported by ProMaster owners from various years include the following:

• Electrical system glitches (sensors, lighting, and body control modules) that can trigger warning lights or intermittent function.


• Transmission and shifting concerns (hesitation, rough shifts, or software calibration quirks) in some aged or high-mileage examples.


• Diesel-related maintenance for EcoDiesel variants (DPF/DEF system, exhaust aftertreatment, and periodic regenerations).


• Rust and corrosion in exposed areas and underbody components, particularly in regions with road salt or heavy use in harsh climates.


• Water intrusion and roof/door seals leading to leaks in certain configurations or after impact damage.


• HVAC and climate-control anomalies that can affect cabin comfort in extreme temperatures.

These issues reflect owner experiences and typical maintenance patterns; many problems are addressable with timely service and a solid maintenance schedule. The ProMaster’s reliability profile can be more favorable for buyers who maintain a strict service regimen and keep up with recalls and software updates.

Maintenance and ownership: tips to maximize reliability

To maximize uptime and minimize repair risk, consider the following best practices for RAM ProMaster ownership:

1. Adhere to the manufacturer's scheduled maintenance, including timing belt/chain checks, fluid services, and filter changes at recommended intervals.


2. Keep the vehicle’s electrical system yard by performing regular battery and charging system checks, and address any fault codes promptly.


3. Monitor the diesel emissions system (for EcoDiesel variants) and have any DPF/DEF-related messages inspected early to prevent more costly repairs.


4. Inspect seals, gaskets, and body hardware for signs of leaks, corrosion, or wear, especially on fleets operating in harsh climates.


5. Ensure timely recall service and software updates from a certified dealer to address known safety and reliability concerns.


6. Document and maintain a complete service history, including parts replaced, to support resale value and predictability of future maintenance needs.

Following these steps can help maximize reliability and reduce downtime, particularly for fleets that rely on the ProMaster for daily operations and long-duty cycles.

Summary

The RAM ProMaster is a capable, spacious cargo van that can deliver reliable service with diligent maintenance. Its reliability profile is mixed and varies by year, engine choice, and how well it’s cared for. Prospective buyers and fleet operators should prioritize a thorough pre-purchase inspection, verify maintenance records, and stay current with recalls and software updates. When properly maintained, the ProMaster remains a competitive option in the cargo-van space, particularly for users who value payload capacity and practical configuration options. For comparison, rivals such as the Ford Transit and Mercedes Sprinter often show different reliability patterns and total ownership costs depending on configuration and usage.

Mechanical and performance issues

• Transmission problems: This is a very common complaint, with issues ranging from shifting hesitation to slipping or failure, especially at higher mileage. Problems can be caused by worn clutch packs or low transmission fluid. 
• Engine problems: Some owners report a "ticking" sound from the engine in earlier models (2014-2016). 
• Cooling system leaks: Leaks from the coolant bottle, radiator, or pipes are a common issue, particularly in earlier models. A 2014 radiator recall was issued for leaking seams.

Electrical and electronic issues

• Electrical malfunctions: Various electrical problems are frequently reported, including issues with the overall system. 
• Rearview camera: The rearview camera is a common source of glitches and malfunctions. 
• Airbag sensors: Some owners have reported the airbag sensors going off unexpectedly. 
• Lights: Headlights and other lights may fail frequently. 

Exterior and interior issues

• Door hinge problems: The hinges on the rear or side doors can be weak and break off. 
• Roof leaks: Some vans have been reported to have roof leaks. 
• Front tire wear: Premature and uneven wear on front tires has been reported. 
• Interior build quality: Some owners report poor interior build quality.

Do ProMasters have transmission problems?

Yes, Ram ProMasters have experienced transmission problems, including a recall for a potential rollaway issue and reports of failure due to water intrusion and failing mounts. Issues can also stem from electrical problems like faulty solenoids, low fluid, or other component failures. Some sources suggest that the use of a transmission not rated for the ProMaster's weight may contribute to these issues. 
Common issues

• Rollaway risk: A recall was issued for 2019-2021 models because the park pawl might not engage fully, increasing the risk of the vehicle rolling away. 
• Water intrusion: Water can enter the transmission via the vent or a worn/split manual shaft bushing, causing failure. This was also the subject of a recall for some 2015-2016 ProMaster City models due to a faulty electrical harness connector. 
• Mount failure: The transmission mounts on early models, particularly 2014s, have a high failure rate, which can lead to the transmission failing or detaching. 
• Electrical and fluid problems: Transmission issues can be caused by faulty shift solenoids, low transmission fluid, or other electrical malfunctions. 

What you can do

• Check for recalls: Verify if your ProMaster is subject to any recalls and have the necessary repairs performed by a dealership. 
• Inspect for water intrusion: If your vehicle experiences transmission problems, check for signs of water intrusion, especially if you've driven in heavy rain or flood conditions. Be aware that water can get in through other means, not just by driving through water. 
• Maintain proper fluid levels: Regularly check your transmission fluid to ensure it is at the proper level and in good condition. 
• Listen for warning signs: Be aware of signs of transmission failure, such as delayed gear shifts, leaks, odd noises or grinding sounds, and the transmission warning light coming on. 
• Get it inspected: If you suspect a transmission problem, have it inspected by a qualified mechanic or transmission shop. Early diagnosis and repair can prevent more severe damage and costly repairs. 
• Consider a transmission rebuild: If the warranty has expired and the transmission needs repair, consider having it rebuilt rather than replaced, as this can be a more cost-effective solution and may result in a more reliable unit.
