🚨 The Verdict
Ram 1500 trucks are popular, capable, and broadly likable. But not every model year is built the same. Two specific eras account for the vast majority of complaints filed with the NHTSA and CarComplaints.com. If you are cross-shopping a used Ram, knowing which years to skip can save you a $6,000 repair bill in the first 12 months of ownership.
Below is the data-driven rundown: which years to avoid, why, what they typically cost to fix, and the safer alternatives that get you the same truck without the risk.
📋 The 5 Worst Years at a Glance
| Year | Main Problem | Typical Repair Cost | Miles Until Failure |
|---|---|---|---|
| 2014 | 5.7L HEMI MDS lifter / cam failure | $4,500 - $7,000 | 80k - 120k |
| 2013 | 5.7L HEMI MDS lifter, TIPM electrical | $4,000 - $6,500 | 85k - 130k |
| 2015 | HEMI lifter, 8-speed ZF shift quality | $4,000 - $7,000 | 90k - 140k |
| 2006 | 45RFE/545RFE transmission, rust | $2,800 - $4,500 | 110k - 160k |
| 2003-2005 | Transmission, dash crack, ball joints | $2,500 - $4,200 | 100k - 150k |
💥 Why 2013-2015 Are the Worst
The third-generation Ram 1500 (DS platform) launched in 2009 and ran through 2018. By 2013, the 5.7L HEMI with Multi-Displacement System (MDS) had accumulated enough miles in the field to expose a serious design flaw. The MDS cylinder-deactivation lifters collapse, scoring the camshaft and sending metal shavings through the engine.
The failure is loud and unmistakable: a tapping or ticking from the top of the engine, often paired with a misfire code like P0301 or P0306. By the time you hear the tick, the cam is usually scored and both the lifters and camshaft need replacement.
What the repair actually costs
- Independent shop: $4,000 to $5,500 for full lifter and cam replacement
- Dealer: $6,500 to $9,000, sometimes including head work
- Used engine swap: $5,500 to $8,500 installed (gamble on history)
- Preventive MDS delete + cam: $3,500 to $4,800 if done before failure

🛢️ The 2014 EcoDiesel Special Warning
The EcoDiesel was marketed as the fuel-economy hero of the lineup. In practice, the early 2014-2016 trucks logged so many EGR cooler and oil cooler failures that Stellantis issued an extended warranty. Average repair on a failed EGR cooler runs $1,800 to $3,200, and a head gasket job on the V6 diesel can hit $5,500.
Pair that with the diesel emissions settlement and ongoing software updates, and the 2014 EcoDiesel becomes a high-stakes purchase even when the price looks attractive.
🔧 Why 2003-2006 Are on the List
The second-generation Ram (1994-2001) is broadly liked for its simplicity. The 2002 redesign brought modern styling, the third-gen interior, and unfortunately a transmission that struggled to keep up. The 45RFE and 545RFE automatics paired with the 4.7L V8 and 5.7L HEMI in 2003-2006 develop slipping, harsh shifts, and full failures somewhere between 110,000 and 160,000 miles.
Other 2003-2006 problems
- Dashboard cracking: sunlight degrades the dash material, leaving deep splits across the top
- Ball joints and tie rods: front-end wear is chronic, especially on 4x4 trucks
- Frame and rocker rust: trucks from salt states routinely fail at the cab corners and rear frame section
- Steering wander: a TSB exists but the underlying geometry never fully went away

✅ The Safer Ram 1500 Years
Not every year of Ram 1500 is a risk. These model years have meaningfully fewer complaints, better drivetrain reliability, and reasonable parts availability.
| Year | Why It Works | What to Still Check |
|---|---|---|
| 2010-2011 | Pre-MDS-failure era, simple electronics | Exhaust manifold bolts, TIPM |
| 2016-2017 | Updated valvetrain, refined 8-speed | Lifter ticking at 100k+ |
| 2019-2021 (DT gen) | New platform, revised lifters, eTorque | Infotainment glitches, software |
| 2022+ | Most durable HEMI variant to date | Recall history, regular OTA updates |
⚠️ Common Mistakes Used Ram Buyers Make
- Trusting a quiet idle. MDS lifter failure often only ticks under load or at warm idle. A 5-minute test drive in the dealer lot will not catch it.
- Skipping the VIN-based recall check. The TIPM (Totally Integrated Power Module) on 2011-2014 trucks has multiple recalls. Make sure they were performed.
- Ignoring transmission fluid color. On 2003-2006 trucks, dark or burnt-smelling ATF predicts a $2,800 rebuild within 20,000 miles.
- Falling in love with the EcoDiesel price. A cheap diesel Ram usually means someone is offloading it before the next big bill.
- Not budgeting for preventive work. If you buy a 2013-2015 HEMI, set aside $4,500 the day you sign. You are buying time, not avoidance.
🧭 Quick Decision Framework
Use this if you have a specific Ram 1500 in front of you:
- Year is 2013, 2014, or 2015 with 5.7L HEMI: only buy if lifters and cam were replaced (get the receipt) or you can negotiate $5,000 off.
- Year is 2014-2016 EcoDiesel: verify EGR cooler replacement was done under the extended warranty.
- Year is 2003-2006: only buy with a fresh transmission service record and a clean frame inspection.
- Year is 2010-2011 or 2016-2017: normal used-truck inspection, no special concerns.
- Year is 2019 or newer: check for open recalls and an updated infotainment software version.
For any check-engine codes that pop up on a test drive, cross-reference them in our DTC code library before you walk away or negotiate.

📌 Summary
The worst years Ram 1500 shoppers should avoid are 2013, 2014, 2015, and the 2003-2006 cluster. The first group will cost you a $5,000 HEMI repair. The second group will cost you a $3,500 transmission. The 2014 EcoDiesel deserves a separate caution flag thanks to EGR cooler and head gasket failures.
If you want the Ram look without the lottery odds, target a 2010-2011, 2016-2017, or 2019+ truck with documented service. And whatever you are about to buy, run the VIN, listen for ticking at warm idle, and pull the transmission dipstick before you sign.
