The 1989–1998 Dodge Ram 2500 is widely regarded as a benchmark for durability and reliability in heavy-duty pickups, largely due to its 5.9L 12-valve Cummins turbo diesel engine. This engine has earned a reputation for “million-mile” longevity, with many trucks surpassing 500,000 miles on their original turbo and internals.
Its mechanical simplicity, overbuilt components, and robust inline-six design make it a favorite among diesel enthusiasts and those seeking a truck that can handle both work and long-term ownership with minimal electronic complexity.
The 12-valve Cummins engine features a mechanically controlled fuel injection system, meaning it can operate with little to no electrical power once started. The engine’s overbuilt internals, including a cast-iron block, forged-steel crankshaft, and I-beam connecting rods, were originally designed for industrial and agricultural use, allowing it to handle far more stress than factory horsepower demands.
From 1994 to 1998, Dodge introduced the Bosch P7100 inline injection pump, known for near-eternal service life and easy tunability for increased power with basic tools. The inline-six configuration reduces internal vibration and provides ample space in the engine bay, making maintenance straightforward.
Durable Holset turbochargers were matched to handle more boost than stock settings, further enhancing the engine’s reputation for toughness. The only significant engine concern is the “Killer Dowel Pin” issue, which can be mitigated with a simple retainer kit.
The 1989–1998 Ram 2500 also marked a turning point in truck design. The 1994 redesign introduced the “Big Rig” styling, a more aggressive grille, and improved interior space. By 1998, the Quad Cab added rear-opening doors for practical rear seating, transforming the Ram from a utilitarian workhorse into a family-capable pickup.
While the Cummins diesel dominates in reliability, the trucks’ supporting systems have weaknesses. Automatic transmissions like the 47RE often slip or overheat under heavy towing. Second-generation dashboards are prone to cracking, and the heavy engine places stress on front suspension components, leading to steering “slop” over time.
Despite these issues, the 1989–1998 Dodge Ram 2500 remains a favorite among enthusiasts who value mechanical simplicity, towing capability, and the legendary durability of the 12-valve Cummins diesel.
Whether in the First-Gen (1989–1993) or Second-Gen (1994–1998) form, the Ram 2500 represents an era when trucks were built to endure, offering a “lifetime” vehicle for owners willing to maintain the cosmetic and suspension elements over time. Its combination of reliability, overbuilt engineering, and towing grunt cements its status as a classic in American truck history.

5 That Have Frequent Issues
1. BMW 550i (F10): The N63 “Hot-V” V8 and Its Reliability Challenges
The BMW 550i (F10, 2011–2016) is powered by the 4.4L N63 twin-turbo V8, an engine known for frequent and costly reliability problems. Central to these issues is BMW’s “Hot-V” design, which places the turbochargers inside the engine’s V-bank.
While this layout reduces turbo lag, it traps extreme heat, accelerating the degradation of rubber and plastic components, gaskets, hoses, and seals. The high temperatures also contribute to premature turbocharger failures, wastegate issues, and cooling system problems such as broken plastic connectors, water pump failure, and radiator leaks, often resulting in engine overheating.
The N63 suffers from significant oil consumption. Valve stem seal failures are common, causing heavy oil burning and visible smoke. External leaks from the valve cover and oil pan gaskets further reduce oil pressure and increase maintenance demands.
Internally, the engine experiences timing chain stretch, which can lead to severe engine damage, and cases of cylinder wall scoring have been reported, sometimes necessitating full engine replacement.
The fuel system is another weak point. High-pressure fuel pumps (HPFP) and fuel injectors frequently fail, producing rough idle, misfires, and triggering “drivetrain malfunction” limp modes. Carbon buildup on intake valves, a common problem in direct-injection engines, further reduces performance and contributes to misfires. Heat-related battery drain is also common, requiring more frequent replacements.
BMW attempted to address these issues with the N63 Technical Update (N63TU) in 2014, which strengthened timing chains and improved heat management. While these updates reduced some failures, the N63TU still requires high maintenance and remains less reliable than BMW’s inline-six N55 engine.
The F10 550i delivers strong performance and the appeal of a twin-turbo V8, but owners should expect frequent maintenance and costly repairs due to the engine’s inherent design and heat management challenges. Even with the 2014 update, the N63 is considered high-maintenance compared to other BMW engines.
2. Ford Escape (2013–2016): EcoBoost Engines and Critical Reliability Issues
The 2013–2016 Ford Escape, particularly models equipped with the 1.6L and 2.0L EcoBoost engines, are infamous for severe reliability problems. These turbocharged engines suffer from fundamental design flaws and extreme thermal stress, often leading to catastrophic failures or even engine fires.
The 2013 Escape earned a “Avoid Like the Plague” rating from CarComplaints.com due to the frequency and severity of these issues.
A primary concern is coolant intrusion and the open-deck engine design. The thin walls of the cylinder block lack sufficient support, making them prone to warping or cracking under heat and load. This allows coolant to seep into the combustion chambers, triggering misfires, white exhaust smoke, and ultimately engine seizure.
For affected 2013–2016 models, the only permanent solution is often a full engine replacement, which can exceed $8,000. Later designs corrected this with a more robust closed-deck block, but early models remain vulnerable.
The 1.6L EcoBoost is particularly prone to overheating and fire risks. Localized cylinder head cracks can cause pressurized oil leaks onto hot components, while dislodged freeze plugs or compromised fuel lines may result in rapid coolant loss and engine fires. These defects prompted multiple safety recalls, though the risks persisted in many vehicles prior to remediation.
Turbocharger and carbon buildup issues further complicate ownership. Turbo failures can occur due to inadequate lubrication or oil contamination, while carbon deposits from direct-injection engines reduce efficiency, cause rough idling, and often require walnut blasting every 60,000 miles. Additionally, the 6F35 automatic transmission is prone to premature failure, producing jerking, hesitating shifts, or complete loss of power.
The 2013–2016 Ford Escape EcoBoost engines are high-risk for severe engine and turbocharger failures. Owners are strongly advised to monitor recalls, address maintenance rigorously, and consider potential class-action settlements for powertrain defects. These vehicles, while offering small-displacement turbo efficiency, carry significant long-term reliability concerns.
3. Audi A4 (B8): 2.0L TFSI Engine Reliability Concerns
The Audi A4 B8 (2009–2012), equipped with the 2.0L TFSI (EA888 Gen 2 / CAEB) turbocharged engine, is widely known for recurring reliability issues. Early direct-injection engineering, combined with high-stress operation, led to severe oil consumption, timing chain failures, and carbon buildup, making maintenance critical for longevity.
A primary concern is excessive oil consumption in early 2.0L engines. Poorly designed piston rings allowed oil to enter the combustion chamber, causing engines to burn roughly a quart every 500 miles.
Resolving this issue often requires replacing the pistons and rings, a costly repair. Contributing factors include high operating temperatures, poor oil management, and a faulty PCV system, which can cause incorrect crankcase pressure and exacerbate oil loss.
The timing chain tensioner is another major weak point. Failure can lead to the chain skipping teeth, resulting in valves striking pistons and catastrophic engine damage. Early warning signs, such as rattling at startup, should never be ignored.
Carbon buildup on the intake valves is also common due to the direct-injection design keeping fuel out of the intake manifold. This reduces airflow, causing misfires, rough idling, and decreased engine power over time.
Additional reliability concerns include plastic water pump housings prone to failure, coolant leaks, ignition coil malfunctions, and high-pressure fuel pump (HPFP) issues. Turbocharging, combined with these design flaws, increases stress on engine components, making proactive maintenance essential.
To minimize problems, owners should use high-quality synthetic oil with shorter service intervals, perform carbon cleaning (such as walnut blasting) every 60,000–80,000 miles, and proactively replace the timing chain tensioner, PCV valve, and water pump.
While the B8 A4 offers strong performance and refinement, its 2.0L TFSI engine requires careful maintenance and vigilance to avoid catastrophic failures and ensure long-term reliability.
4. Subaru WRX STI (VA): The Fragile 2.5L EJ257 Engine
The Subaru WRX STI VA generation (2015–2021) is powered by the 2.5L EJ257 turbocharged Boxer engine, a platform celebrated for performance but notorious for fragility.
While capable of impressive power and handling, the EJ257 suffers from inherent design limitations, high operating temperatures, and sensitivity to maintenance and modifications. Common engine failures include piston ringland cracks, rod bearing damage, oil starvation, head gasket leaks, and turbocharger issues.
One of the most frequent problems is piston ringland failure. The grooves that hold the piston rings are thin, and high cylinder pressures or heat, particularly under aggressive driving or improper tuning, can cause them to crack. This leads to compression loss, power reduction, and excessive smoke from the exhaust.
Similarly, rod bearing failure is a critical concern. The EJ257 is highly sensitive to oil levels, and high-RPM performance driving or neglected oil maintenance can cause bearings to spin, resulting in catastrophic engine knock and potential engine destruction.
Heat management is another weak point. The turbocharged EJ257 runs hot, often leading to premature gasket and seal failures, including valve cover gaskets and oil pans. Head gasket leaks are also persistent, even in later model years, due to the engine’s Boxer layout and thermal stress.
The EJ257 is also highly sensitive to aftermarket modifications. Changes to intakes, exhausts, or fuel systems without proper ECU tuning can create dangerously lean air/fuel conditions, immediately risking engine failure. High-stress usage accelerates wear further, as the platform is based on older turbocharged technology compared to modern engines.
To preserve engine longevity, owners must prioritize strict maintenance, including regular oil checks, proper cooling system care, and cautious tuning practices.
Addressing unusual engine noises promptly and avoiding untested performance modifications are essential for preventing costly repairs. While the VA WRX STI offers thrilling performance, the EJ257 remains a high-maintenance engine requiring diligence to avoid catastrophic failures.
5. Honda CR-V (2017–2018): 1.5L Turbo Oil Dilution and Engine Concerns
The 2017–2018 Honda CR-V, equipped with the 1.5L Earth Dreams turbocharged engine, is known for persistent mechanical issues, most notably oil dilution. This problem occurs when unburned gasoline seeps past the piston rings into the oil pan, thinning the engine oil and reducing its ability to lubricate.
Cold climates and frequent short trips exacerbate the issue, as the engine does not reach sufficient operating temperatures to fully vaporize fuel. Symptoms include a rising oil level on the dipstick and a noticeable gasoline odor inside the cabin, which can lead to premature engine wear or catastrophic failure if left unaddressed.
Other common engine concerns stem from the direct-injection design. Carbon buildup on intake valves reduces airflow, causing rough idling, hesitation under acceleration, and decreased fuel efficiency.
Premature head gasket failures have also been reported, sometimes before 100,000 miles, resulting in coolant leaks, overheating, and power loss. Additionally, failing or clogged fuel injectors can trigger warning lights and force the vehicle into “limp mode.”
Secondary failures are often linked to oil dilution. Turbochargers suffer from inadequate lubrication due to thin oil, which can result in early component failure. Excess fuel in the oil can also cause engine stalling and unpredictable power loss. Electrical systems may react to these conditions, triggering multiple warning lights simultaneously.
Honda addressed these issues with Technical Service Bulletins (TSBs) and a product update in 21 cold-weather states, adjusting the ECU and transmission software to help engines reach proper temperatures faster. The manufacturer also extended the powertrain warranty for affected models to six years with unlimited mileage.
Owners are advised to use high-quality full-synthetic 0W-20 oil and regularly drive the vehicle on highways for at least 20 minutes weekly to burn off excess fuel. While the CR-V remains a popular compact SUV, the 2017–2018 1.5L turbo engines require vigilance to prevent costly oil dilution-related damage.
Examining these ten turbocharged engines underscores a key lesson: reliability is as much about thoughtful engineering as it is about maintenance and usage. The reliable engines on our list prove that with robust internals, advanced thermal management, and smart design choices, turbocharged motors can deliver decades of high performance with minimal issues.
On the other hand, engines prone to frequent failures, like the Honda CR-V 1.5L turbo or Audi A4 B8’s 2.0 TFSI, demonstrate how high stress, poor heat control, or sensitive components can quickly turn a thrilling ride into a maintenance nightmare.
Prospective buyers and enthusiasts should weigh not only horsepower and performance figures but also the long-term durability of turbo engines, ensuring that the thrill of forced induction does not come at the cost of reliability or unexpected repair bills.
