Used Ram 1500: What to Know Before You Buy

The Ram 1500 is the only half-ton pickup with a standard coil-spring rear suspension. That one engineering choice gives it a noticeably better ride than the leaf-spring F-150, Silverado, and Tundra while still towing and hauling competitively. Owners who stick with it long-term routinely report 200,000+ miles on the 5.7L Hemi V8.

But the Ram has real, generation-specific failure patterns that can cost $5,000 unannounced. The 5.7L Hemi's Multi-Displacement System can destroy a camshaft. The optional air suspension has an expensive cold-weather failure chain. The 2019 model year launched with 29 NHTSA recalls. None of this disqualifies the truck. All of it needs to be on your checklist before you hand over money.

Generations at a Glance

Three different trucks wear the Ram 1500 badge in the used market right now.

4th Generation (DS platform, 2009–2018)

The backbone of the used inventory. The 2013 refresh was the meaningful one: the old 3.7L V6 was replaced by the 3.6L Pentastar, and the 5-speed automatic gave way to a ZF-derived 8-speed. The 3.0L EcoDiesel V6 arrived for 2014. The optional 4-corner air suspension became available starting 2013. Pre-2013 trucks (2009, 2010, 2011, 2012) have the old drivetrain and are mostly past this guide's scope for value-shopping.

4th Gen Classic (DS platform, 2019–2024)

When Ram launched the 5th gen in 2019, they kept building the old body as the "Ram 1500 Classic" as a price-entry option for 6 more years. These look identical to 2013–2018 trucks but carry newer model year badges. No eTorque, no 12-inch screen, none of the 5th gen safety tech. The last Classic rolled off the line in October 2024. This matters because sellers sometimes list them without the "Classic" designation, and buyers pay 5th gen prices for a 10-year-old platform.

5th Generation (DT platform, 2019–present)

A complete redesign from the cab to the tailgate. About 200 lbs lighter than the DS platform. Most trims come standard with a 12-inch Uconnect touchscreen. The eTorque mild-hybrid system is standard on the 3.6L V6 and was optional on the 5.7L V8. Air suspension is available. This truck has its own distinct failure patterns.

What Owners Actually Report

4th Gen (2013–2018): The MDS Problem

Every 5.7L Hemi V8 — across all generations — uses a cylinder deactivation system called MDS. At light throttle, it shuts off cylinders 1, 4, 6, and 7. The deactivation lifters receive reduced oil at low RPM. In a significant number of engines, that starves the roller, which seizes, and then grinds the corresponding camshaft lobe off. Symptom: a rhythmic tick that follows engine RPM, does not fade at operating temperature, and eventually triggers a cylinder misfire code. The truck goes into limp mode. The RamForumZ cam and lifter failure thread ran to 52+ pages.

Repair cost: $3,500 to $5,000+ at an independent shop. Some owners choose a remanufactured engine at around $4,000 plus labor.

There is a meaningful dividing line within this generation. Ram supplier Melling released updated replacement lifters in early 2015, and FCA began installing them in production starting with 2016 model year trucks. Pre-2016 Hemi trucks carry meaningfully higher MDS failure risk. FCA issued a Technical Service Bulletin confirming the defect but never issued a recall. Many owners install an MDS disabler device (plugs into the OBD-II port, brands like Edge or Superchips, cost $100–$500) to keep all 8 cylinders firing permanently. A used truck that already has one is a positive sign.

Distinguish the MDS tick from the exhaust manifold tick. The manifold bolts are well-known for shearing or cracking with heat cycling on the 5.7L. That tick starts cold, slows, and fades completely at operating temperature. Cost: $300–$800 per side. The MDS failure tick does not quiet down with heat. It follows RPM.

The 8-speed ZF transmission shudder is the second-most-documented issue. The ZF 8HP70 arrived for 2013. At light throttle between 15 and 50 mph, just before the torque converter locks up, owners report a vibration or shudder. Forum threads across RamForum.com and RamForumZ run to multiple pages. Problems typically surface at 95,000–150,000 miles. A key contributing factor: dealers routinely told owners the ZF fluid was a "lifetime fill." It is not. ZF specifies a fluid and filter change every 60,000 miles. Overheated, never-changed fluid degrades the torque converter friction material and causes the shudder. A fluid and filter service ($150–$250) often resolves it entirely. If not: torque converter replacement ($1,500–$2,500) or full transmission replacement ($5,000–$6,000). A PCM flash update via TSB can help shift calibration.

The 3.0L EcoDiesel (2014–2019) has a documented fire risk. The EGR cooler develops microcracks that leak coolant into the intake manifold. NHTSA recall 19V757000 covered this, but parts were backordered 30+ days for many owners. Gen 1 EcoDiesel (2014–2016) also had a fuel economy rollback after an EPA-mandated software update. The CP4.2 high-pressure fuel pump on the diesel is a separate failure: metal debris contaminates the entire fuel system and requires a full replacement at $3,000–$6,000 (recall 22V406000). Owner communities are direct about this: avoid the Gen 1 EcoDiesel unless you can verify both recalls are closed and the fuel pump has been addressed.

The optional 4-corner air suspension (2013–2020) has an expensive failure chain. Air bags degrade and begin leaking at 80,000–100,000 miles. A leaking bag forces the compressor to run constantly. The compressor burns out. Sequential repairs run $2,000–$4,500. In temperatures below freezing, the compressor ingests moisture-laden air, the onboard dryer saturates, and moisture freezes in the valves. Owners in Canada filed a class action covering 2013–2020 trucks. One North Dakota owner reported being "the 5th truck that morning" at the dealer with air suspension failure. Community consensus: if you live where it freezes regularly, buy a coil-spring truck or budget $1,500–$2,000 for a coil spring conversion kit.

On the 3.6L Pentastar V6, the oil filter housing and oil cooler assembly crack at 80,000–110,000 miles. Shops treating it as routine maintenance, not a surprise. Cam phaser and oil control valve wear is documented in the forum community and a class action was filed in 2022 in four states for the valvetrain defect on 2014–2020 engines. Despite this, a well-maintained Pentastar reaches 250,000–300,000 miles routinely.

5th Gen (2019–present): First-Year Issues, eTorque, and Screen Problems

The 2019 model year is the one to approach most carefully. It recorded 29 NHTSA recalls — nearly double every other year in the model's history. The 5th gen launched on a new platform assembled at a retooled factory, and first-year teething shows in the data. Documented 2019-specific issues: brake pedal detachment covering approximately 220,000 trucks (recall), body control module causing overnight battery drain, ParkSense sensor failures, rear window encapsulation leaks, and door lock electrical faults. The platform itself is a genuine improvement over the DS. But a 2019 truck needs every recall verified before purchase.

Later production 2019s (build date on the door jamb sticker shows fall 2019 or later) are cleaner than early builds. The 2020 and 2021 models are substantially better across the board.

eTorque is the 5th gen's highest-stakes unknown. Ram's belt-integrated starter-generator is standard on the V6 and was a $1,450 option on the V8. It adds complexity. Known failures: unexpected engine stall from an over-rich fuel condition (PCM recall covering 131,700 trucks, 2020–2021 builds), 12V battery drain that disables power steering, brake assist, blind spot detection, and emergency flashers simultaneously, and Motor Generator Unit failure at unknown replacement cost. Ram extended the eTorque system warranty to 8 years / 80,000 miles after lemon law pressure. For trucks past that threshold, budget for MGU replacement as an unknown cost. Many owners report zero issues past 60,000–80,000 miles; others advise avoiding eTorque on a used buy.

The 12-inch Uconnect screen on early 5th gen trucks has documented reliability issues. Screen delamination (the surface peels away in heat) was common on 2018 refreshes and early 2019 trucks. Dealer replacement cost: $1,500. Random reboots, backup camera lockups, and software glitches are active forum topics on 5thGenRams.com. Some owners cycled through 3–4 replacement units under warranty. The 2022 update to Uconnect 5 (Android-based, wireless CarPlay, OTA updates) significantly improved the software side.

The rear window water leak persists across both generations (documented 2016–2022). The third brake light housing gasket fails and channels water through the headliner to the rear floor corners. On eTorque trucks, water near the lithium battery pack behind the rear seat is a concern. One dealer service advisor confirmed seeing it on roughly 20% of Ram 1500s that come through for service. DIY fix: EPDM weatherstrip tape, under $30. Dealer repair for a cracked rear window encapsulation: $500–$900.

What to Inspect Before Buying

On any 5.7L Hemi V8 (any generation):

• Start the truck cold. Listen for a tick that increases in frequency with RPM. Exhaust manifold ticks are cold-start only and fade at operating temperature. A tick that follows RPM and does not fade is MDS lifter failure. Walk away.
• Pull the oil dipstick. Sludge or dark, gummy oil is exactly the maintenance condition that triggers MDS cam destruction.
• Ask if MDS has been disabled. A tune or disabler device is a green flag.
• Ask for oil change records. Hemi MDS failure is oil-quality-dependent.

On any truck with optional air suspension:

• Check the truck is riding level before the test drive. One sagging corner means a failed air spring.
• Ask if the compressor has ever been replaced.
• Noting the seller's climate: 80,000+ miles in Minnesota or Canada means the air suspension likely needs attention.

On any 2014–2019 EcoDiesel:

• Run the VIN at /tools/recall-lookup and confirm recalls 19V757000 (EGR cooler fire risk) and 22V406000 (fuel pump contamination) are both completed.
• Ask about DPF maintenance history. An unserviced DPF on a high-mileage diesel is a problem.

On any 2019 (5th gen):

• Run the VIN. All 29 NHTSA recalls need to be verified closed.
• Push the brake pedal to full travel and confirm it does not feel like it is pulling away from the mount.
• Check rear floor corners for moisture.

On any 5th gen eTorque:

• Confirm the PCM recall (stall risk, 131,700-truck campaign) is completed.
• Check 12V battery age. eTorque management wears conventional batteries faster than non-eTorque trucks.

On any 5th gen with the 12-inch screen:

• Look for delamination at screen edges and corners.
• Test the backup camera before and during the drive.

For towing buyers:

• Check the door jamb sticker for axle ratio and tow package status. Two identical-looking 5.7L V8 Ram 1500s can have maximum tow ratings of 6,500 lbs vs. 12,750 lbs. The sticker tells you which one you're buying.

Running Costs

EPA fuel economy (combined):

• 3.6L Pentastar V6, 4th gen: 20–22 MPG
• 5.7L Hemi V8, 4th gen: 17–19 MPG
• 3.0L EcoDiesel V6, 4th gen: 22–25 MPG
• 3.6L Pentastar V6 with eTorque, 5th gen: 22–24 MPG
• 5.7L Hemi V8 with eTorque, 5th gen: 19–22 MPG

Key maintenance items:

• Oil change interval: every 8,000 miles (longer than most rivals)
• Transmission fluid: every 30,000–45,000 miles if towing regularly; 60,000–80,000 miles otherwise
• Air suspension air bags: plan for replacement at 80,000–100,000 miles on equipped trucks
• EcoDiesel DPF service: every 100,000–200,000 miles depending on driving mix

RepairPal estimates $691 per year in repair costs for the Ram 1500, vs. $788 for the F-150. One documented owner tracked $9,036 in maintenance and repairs over 8.5 years and 139,000 miles on a 2013 5.7L V8. The 5.7L Hemi that avoids MDS failure is well-documented running to 200,000–250,000+ miles.

Which Generations to Target (and Which to Skip)

Target: 5th gen (DT), 2021–2022

The first-year 2019 issues are gone. The 2021 adds HUD, forward-collision warning, digital rearview mirror, and trailer reverse steering control. The 2022 brings Uconnect 5: Android-based, wireless CarPlay, and over-the-air software updates. You get the modern platform without the first-year quality lottery. On eTorque trucks, verify the PCM recall is done and check 12V battery condition.

Target: 4th gen (DS), 2016–2018 with 5.7L Hemi, coil springs

Melling's updated lifters are in the engine from the factory. The 8-speed ZF is established. These are high-mileage-capable trucks with a well-understood failure profile you can inspect against before buying. Skip the air suspension option unless it has documented service history and you are in a warm-weather state.

Approach with caution: 4th gen, 2013–2015 with 5.7L Hemi

The 2014 is the single worst Ram 1500 model year by complaint volume — 2,588 CarComplaints entries, ranking it last in the entire lineup. Transmission shudder and lifter failures dominate. Buy 2013–2015 only with full service records and a pre-purchase inspection specifically checking for MDS lifter condition. Any RPM-following tick is a disqualifier. Ask specifically whether transmission fluid was ever changed — many of these trucks have original fluid.

Skip: 2014–2016 EcoDiesel (Gen 1)

Two active recalls, an emissions software rollback that hurt fuel economy, and a fuel pump that can take the entire fuel system with it. The Gen 3 EcoDiesel on the 2020–2023 DT platform is the version forum communities trust.

Skip: Early-production 2019 5th gen

The platform is solid but the first calendar year of production was rough. If buying a 2019, prioritize trucks built in fall 2019 or later (door jamb build date), and require all 29 NHTSA recalls completed before purchase.

Bottom Line

Run every VIN through a recall check before anything else. On any Hemi V8, an RPM-following tick that does not fade at operating temperature is a hard walk-away. Budget for air suspension replacement on any DS-platform truck with the optional system at 80,000+ miles. The 2021–2022 5th gen with the 5.7L V8 is the sweet spot: a maturing platform, post-first-year quality settled, and a screen that actually works.
