NHTSA Complaint #11465410 — 2016 RAM 1500

My 2016 RAM 1500 Laramie Crew Cab 5.7 Liter HEMI engine has an engine ticking sound that is most noticeable when the truck is first started when the engine is cold. The ticking sounds does start to go away after one to three minutes, when the engine temperature increases. The ticking noise happens both in the winter and summer when the engine is cold. This engine noise first became noticeable when the truck was two years old with approximately 30,000 miles. I purchased the RAM 1500 Laramie new on October 5, 2016. I am a former Nissan service technician. I am acutely aware of the importance of changing engine oil and oil filter at the manufacturer recommended intervals. I am VERY diligent about changing the engine oil and oil filter every 5000 miles with Mobil One synthetic or Pennzoil Platinum synthetic 5W-20 oil. As of May 20, 2022, my RAM 1500 Laramie has 76,040 miles. Other RAM 1500 5.7-Liter HEMI engine owners have reporting a ticking sound when the exhaust manifold bolts break. I inspected the exhaust manifold bolts on May 20, 2022, and they are not broken.
