Shortly after a "low oil pressure" message appeared the vehicle shutdown and coasted to a stop before a suitable place to investigate the issue could be found. Vehicle would not restart. An "low oil add two quarts message" appeared. Engine temp was ordinary. No issues observed under the hood. Oil was found to be dripping from the engine bay to the rear passenger area under the passenger side of the truck. Dealer mechanics diagnosed a catastrophic loss of oil and engine seizure. My wife and I were stranded approximately 800 miles from home and had to arrange for travel home. The vehicle is currently sitting at the dealership in Lincoln, Illinois awaiting my approval for an engine replacement, while I work out the details of a resolution with Ram Care/Stellantis.

Vehicle: 2026 Ram 1500 Limited I am filing a safety complaint regarding a brand new vehicle that experienced a dangerous failure in live traffic and continues to have unresolved issues. The vehicle was purchased on March 31, 2026. On April 3, 2026, just three days after purchase, the truck broke down in active traffic. The situation was serious enough that local police had to respond to direct traffic while the vehicle was towed. This created a clear safety hazard for both the occupants and other drivers on the road. The vehicle was taken to the dealership on April 4, 2026 for repair. At that time, the dealership replaced the battery and reset a radio frequency module. We were notified the vehicle was repaired and ready for pickup on April 7, 2026. However, immediately after leaving the dealership, the vehicle began experiencing additional failures. The key fob would not function, the doors would not lock or unlock electronically, and the vehicle struggled to start. Within minutes, the check engine light illuminated. Due to safety concerns, the vehicle was returned to the dealership the same day. After returning the vehicle, we were informed that there is a short in the main PDC (power distribution center / fuse box). This critical issue was not identified or addressed during the initial service visit. A fault in the main fuse box presents a serious safety concern, including the potential risk of an electrical fire. Additionally, the dealership failed to properly verify the repair before releasing the vehicle. The truck was not adequately tested or driven after the initial repair, resulting in us being sent to pick up a vehicle that was still unsafe and malfunctioning. This vehicle has been in our possession for approximately one week and has already experienced multiple serious failures, including a breakdown in live traffic, repeat electrical failures, and now a confirmed issue within the main power distribution system. The vehicle is unreliable and poses

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2026 Ram Ram 1500 Quad Cab verdict →
