JEEP Wrangler 2012 Unlimited 3.6L V6 engine ERB
Engine reliability and common problems:
The variable valve timing regulators, oil pump, water pump, and thermostat are known for their limited lifespan. Another common issue is the clogging of oil channels with wear particles.After 100,000–150,000 km, the engine oil cooler, which also houses the oil filter, often begins to leak. It’s recommended to replace the entire unit with a genuine part, as non-original replacements are unreliable. Most of the time, oil leaks into the engine's V-section, in some cases, it mixes with coolant, causing serious complications.
The crankshaft seal is not reliable, and the thermostat housing often cracks. Additionally, for the first 20–30 seconds after engine start, particularly in near-zero or sub-zero temperatures, the accessory belt roller tends to make noticeable noise.
Overall, this engine can last around 290,000 to 490,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.
