RAM 1500 Common Problems: What Australian Owners Should Watch For

Is the RAM 1500 reliable in Australia?

Yes — with a caveat. The RAM 1500 is a strong, durable truck, but it's a complex one: a big V8, an 8-speed automatic, and on many models air suspension and a long list of electronic modules. The problems below aren't reasons to avoid the truck; they're the known weak points that a specialist workshop checks routinely and that owners should budget awareness for. Almost all of them are dramatically cheaper to fix early than late.

1. HEMI lifter tick and cam wear (5.7L V8)

The best-known RAM 1500 issue. A ticking noise from the top of the engine, often worse at idle when warm, can indicate a failing hydraulic lifter. Left alone, a collapsed lifter grinds the camshaft lobe, sending metal through the engine — turning a moderate repair into an engine-out job.

• Symptom: rhythmic tick from the engine top end, especially at warm idle
• Cause: lifter roller or lifter bore wear; extended oil intervals are a contributing factor
• Early fix: lifter replacement; late fix: camshaft, lifters and possible engine rebuild
• Prevention: correct-spec oil (we use Penrite premium to RAM spec) changed on time, every time

2. 8-speed transmission shudder (8HP70)

A shudder or vibration at light throttle, typically between 40–80 km/h, is a known complaint on the 8-speed. In many cases it's torque-converter clutch behaviour aggravated by degraded fluid — and a correct fluid exchange with the specified fluid resolves or dramatically improves it. Left alone, converter wear can follow. We cover this in depth in our 8-speed and 10-speed shudder guide.

3. Air suspension faults (Air Suspension equipped models)

RAM's optional air suspension is excellent when healthy — self-levelling with a caravan on is genuinely useful. The weak points are the compressor, air lines, valve block and the air bags themselves. Symptoms include the truck sitting low on one corner overnight, a 'Service Air Suspension' message, or the compressor running constantly. Queensland heat and beach salt air are hard on the bags and lines.

• Truck sagging on one corner after sitting = leaking bag or line
• Compressor running constantly = leak or failing compressor
• Options: repair the air system properly, or convert to quality coil/airbag-assist setup
• We diagnose with the factory-level scan tool and pressure-test the system before quoting

4. Broken exhaust manifold bolts

A ticking on cold start that fades as the engine warms is often a broken exhaust manifold bolt — the manifold expands and contracts until a bolt shears, and the gasket starts to leak. It's common enough on HEMIs that we check for it on every service. Caught early it's a bolt extraction and gasket; ignored, the leak can warp the manifold and damage the mating surface.

5. Electronic shifter and warning-light faults

The rotary dial shifter and the RAM's many control modules can throw 'Service Shifter', 'Service 4WD' and similar messages — usually a module, sensor or wiring fault rather than a mechanical failure. They're diagnosed with a manufacturer-level scan tool, not a generic OBD reader. See our full guide to RAM 1500 warning messages for what each one means.

6. Do RAM 1500s have transmission problems?

The 8-speed itself is fundamentally a strong gearbox — the same ZF-designed family used across many European brands. The problems we see are almost always fluid-related (shudder from degraded fluid) or software-related (shift quality fixed by an update), not hard mechanical failures. The exception is neglected trucks that tow heavy on old fluid — which is why we recommend transmission fluid service around every 60,000 km for towing vehicles, regardless of what the 'filled for life' marketing says.

What does RAM 1500 problem prevention actually look like?

• Oil and filter every 12 months/12,000 km (6,000 km if towing) with correct-spec oil
• Transmission fluid exchange around 60,000 km if you tow
• Cooling system and manifold bolt check at every service
• Air suspension inspected annually — bags, lines, compressor
• A specialist who knows the failure patterns, not a generalist learning on your truck
