NHTSA Complaint #11575946 — 2020 JEEP GLADIATOR

The oil pump failed at 23,000 miles, then while traveling on [XXX] in New York, the engine failed at 48,000 miles. Fortunately we exited the freeway before a catastrophic failure could occur. The dealer was contacted and I was informed not to drive the vehicle, but to have it towed to the dealership. At the dealership they found the engine had a severe knock and informed me a complete new engine was needed. The engine was never taken apart for inspection, as they mentioned it would be at my expense, that of an additional $1800.00. The cost for engine replacement was $11916.16. If the engine seized on the freeway, a disaster could have occurred. Dealership stating the oil changes were over their recommendations. Four dealerships were contacted and all had different oil change intervals. Dealership stated the North East is a "severe service" area. The other three Chrysler dealerships never heard of this. Also the oil I ran was Amsoil full synthetic with the oil manufacturer recommending up to 12,000 miles oil change intervals, this dealer states 4,500 miles. Other dealers state "go by the book" of 7,500 to 10,000 miles, one states 6,000 miles, another states 6,500 mile intervals. A little long winded story, point being an engine failure traveling at highway speed could have caused severe, possibly life threatening results. My complaint is on the oil pump failure causing this problem, I base my case revolving around the oil pump failure causing engine oil starvation. The dealer states the engine was still getting oil. The oil pump is a two stage pump, low stage-40 PSI, high stage 80PSI. The high stage of the pump failed, not supplying enough oil to the top of the engine. If 40PSI was sufficient to maintain this engine, Chrysler would not have spent millions of dollars to develop a high pressure stage in this pump. Thank you for your consideration in this case.
