2020 Ram 1500 Common Issues by Mileage

Every common 2020 Ram 1500 issue organized by mileage. Know what breaks at 50k, 100k, 150k+ miles.

Key Takeaways

The most discussed 2020 Ram 1500 common issues show up as **Uconnect/electrical quirks by 20k–40k miles** and **front suspension + brake wear by 50k–70k miles**.
If you have the **5.7 Hemi**, budget for potential **exhaust manifold bolt/manifold repair around 80k–110k miles** (often **$600–$2,800** depending on bolt extraction).
At **150k+ miles**, the biggest financial risks are **transmission work ($2,500–$5,500)** and **air suspension repairs ($1,500–$4,000)** on equipped models.
Service records (tires/alignment, 4x4 fluids, cooling system work) are often the difference between a solid high-mile Ram and an expensive one.

2020 Ram 1500 common issues (what owners report most)

This guide breaks down **2020 Ram 1500 common issues** by mileage milestones (30k, 60k, 90k, 120k, 150k+) using patterns seen in real-world owner complaints and service histories (frequently reported on forums, repair shops, and NHTSA-style complaint trends). Most-talked-about areas on the 2020 Ram 1500 include: - **Uconnect infotainment glitches** (freezing, rebooting, black screen) - **eTorque system quirks** (12V/48V battery-related warnings, start/stop behavior) - **Hemi “tick”/exhaust manifold leaks** (more common on 5.7L Hemi than Pentastar V6) - **Front suspension/steering noises** (ball joints, tie-rod ends, alignment wear) - **Brake wear and pulsation** (pads/rotors earlier than expected for some owners) Note: Costs below are typical **out-of-warranty** estimates in the U.S. and vary by region, engine (3.6 V6 vs 5.7 Hemi vs 3.0 EcoDiesel), trim, and 4x4 equipment.

At ~60,000 miles: suspension wear, cooling/AC issues, and drivetrain fluids

Mileage window: **50,000–70,000 miles** Common issues reported: - **Front-end clunks, wandering, uneven tire wear** - What you’ll notice: popping over bumps, vague steering, inside-edge tire wear - Typical fixes: alignment, tie-rod ends, ball joints, control arm bushings (varies by 2WD/4WD) - Cost: **$120–$200** (alignment) + **$250–$700** (tie rods) or **$600–$1,500** (control arms/ball joints, depending on parts and labor) - **AC performance drop (weak cooling) or intermittent blower issues** - What you’ll notice: lukewarm air, inconsistent fan speeds - Typical fixes: refrigerant leak test/recharge, blower motor/resistor, actuators - Cost: **$200–$450** (diagnose + recharge) or **$350–$900** (blower/resistor/actuator repairs); major leak components can push **$900–$1,800** - **Transmission behavior concerns (8-speed)** - What you’ll notice: harsh 1–2 shifts when cold, delayed engagement, occasional shudder (often software/fluid related) - Typical fixes: software update, fluid service (as recommended), driveline inspection - Cost: **$250–$550** (diagnosis + update/service); major repair costs are higher but less common at this mileage Maintenance that reduces issues at this stage: - Inspect front suspension annually - Keep tires balanced/rotated every **5,000–7,500 miles** - Address small AC leaks early before compressor damage

At ~90,000 miles: Hemi tick/exhaust manifold leaks, steering components, and 4x4 service

Mileage window: **80,000–100,000 miles** Common issues reported: - **5.7 Hemi “tick” (often exhaust manifold leak or broken manifold bolts)** - What you’ll notice: ticking on cold start that may quiet when warm; sometimes exhaust smell - Typical fixes: manifold hardware repair, manifold replacement, bolt extraction - Cost: **$600–$1,500** (hardware/bolt repair) or **$1,200–$2,800** (manifold replacement with labor; higher if bolts snap and extraction is complex) - **Steering/suspension refresh becomes common** - What you’ll notice: clunking, vibration, steering play - Typical fixes: tie rods, ball joints, shocks/struts, wheel bearings (as needed) - Cost: **$800–$2,200** depending on how many components are replaced - **4x4 system maintenance (transfer case + front/rear differential fluids)** - What you’ll notice: binding, noise, or vibration if fluids are neglected - Typical service cost: **$300–$700** for transfer case + both diffs (more if limited-slip additive or severe-duty use) Tip: If you’re shopping used, listen for cold-start ticking and verify records for 4x4 fluid services—especially on trucks used for towing.

At ~120,000 miles: cooling system, sensors, and bigger wear items

Pros

Strong towing/torque (especially 5.7 Hemi), with an 8-speed that drives smoothly when healthy.
Comfortable ride and interior; many owners cite the cabin as a class highlight.
Parts availability is generally good, and common brake/suspension repairs are straightforward at independent shops.

Cons

Uconnect infotainment can be glitchy; module replacement can be expensive out of warranty (**$900–$2,200**).
Front suspension/steering wear can lead to recurring alignments and tire wear if not corrected early (**$600–$1,500+** for major refresh).
Air suspension (if equipped) can become a costly high-mileage liability (**$1,500–$4,000**).

Risk Factors

Frequent towing, oversized tires, or lifted setups can accelerate **transmission heat/wear** and **front suspension** failures (often showing up before 90k miles).
Cold-climate use and short trips can increase chances of **battery/start-stop/eTorque warnings** and can aggravate air suspension leaks.
Poor maintenance history (skipped fluid services, ignored vibrations) raises the odds of **$2,500–$5,500** drivetrain repairs at 150k+ miles.
