RepairPal provides auto repair and maintenance information to consumers. The site collects data on owner-reported problems to determine the reliability of nearly every vehicle on the market. The three most common Ram 1500 problems are as follows:

  • Exhaust manifold bolt breakage — reported by over 300 owners
  • Water leaks due to faulty rear window seals — reported by about 300 owners
  • Multiple coolant leaks — reported by more than 200 owners

They sound like relatively serious problems. Fortunately, none have occurred in thousands of Ram 1500 trucks. Still, below are details about each issue and how to fix it.

Which Ram 1500 models experience breaking exhaust manifold bolts?

Two engines in many older Ram 1500s have experienced trouble with exhaust manifold bolts breaking. These engines are the 3.7-liter V6 and the 4.7-liter V8 in 1995 to 2010 Ram 1500 trucks. Drivers have reported the trouble starting anywhere from 12,300 to 225,000 miles.

Owners should replace the bolts and exhaust manifold gaskets when this issue occurs. Diagnosing the problem ranges from about $260 to $320.

Where does the faulty window seal problem appear for this full-size truck?

Owners of 1996 to 2010 Ram 1500 trucks have reported a rear window seal leak after noticing soaked flooring. If the rear cabin carpet in your Ram 1500 is wet, the rear window seal could be faulty. This Ram 1500 problem requires replacing that part. It typically costs $88 to $111 to diagnose.

Engine overheating most commonly results from coolant leaks

If you experience engine overheating in a Ram truck, coolant leaks are likely the culprit. Mechanics can find this issue in one or more of these areas:

  • The thermostat housing gasket
  • Water pump
  • Heater return tube O-ring at the water pump
  • Intake manifold gasket
  • Timing cover gasket

Due to the number of possibilities, owners experiencing this problem should request an inspection of the cooling system before and after repairs. That will ensure the issue has been resolved.

Fixing this issue costs about $665 to $725 — the most expensive of the three most common Ram 1500 problems.
