On April 30, 2026, Kearny Mesa Toyota in San Diego, California, identified the leak during an inspection when the vehicle had a little over 100,000 miles.  I am concerned that this condition may indicate premature failure of the timing chain cover sealing system and warrant investigation into a potential design or manufacturing defect. An engine sealing system should be sufficiently durable to prevent oil leakage under normal operating conditions. The occurrence of this problem at just over 100,000 miles raises concerns about the long-term reliability of this component and whether similar failures affect other vehicles equipped with the same engine.  Although the leak was described as seepage or oily residue, it may worsen over time. Depending on its severity and location, leaking oil could contact hot engine or exhaust components, potentially causing smoke or creating a fire hazard. Continued oil loss could also compromise engine lubrication, lead to significant engine damage, or result in unexpected vehicle failure. These are potential safety risks associated with the condition, not claims that a fire or engine failure has already occurred.  The oil leak was identified by a Toyota dealership during an inspection. The dealership’s diagnosis and related service records may be available for review upon request. Whether the manufacturer has formally investigated or acknowledged this condition as a defect is unknown.  I respectfully request that NHTSA review this complaint alongside other reports involving timing chain cover oil leaks in 2015 Toyota Highlanders equipped with the 3.5L V6 engine. I ask the agency to determine whether these reports indicate a recurring premature component failure, whether the condition presents an unreasonable safety risk, and whether further investigation or corrective action is warranted.","products":[{"type":"Vehicle","productYear":"2015","productMake":"TOYOTA","productModel":"HIGHLANDER","manufacturer":"Toyota Motor Corporation"}]}]}
