On multiple occasions at highway speeds when coasting for a few seconds roughly 50mph to 70mph, the truck begins to stall/ lose power. We thought it was related to the Auto-idle feature, but the last two events I had it turned off. This has happened 5 or 6 times to me and my wife since about six months after buying the truck. Four of the events — November 2023: [XXX] in New Jersey at ~50 mph, engine lost power, applying gas did nothing. A few seconds later it regained power and made a buzzing noise. [XXX]: On [XXX] in Virginia, going down hill at ~70 mph, the engine lost power without warning, steering & brake pedal began to freeze up as if the truck was turning off when coasting briefly down with the flow of traffic. I pumped the gas pedal to no avail — a couple of seconds later it recovered and started up — and buzzed loudly. I avoided an accident; luckily the vehicle behind us was not tailgating. No lights or warning appeared on the dash. The dealer scanned the truck’s computer and they noted a transmission event code, but nothing more. Could not replicate the issue. [XXX], Jacksonville, FL [XXX] near [XXX] at ~62 mph, in the middle lane with Auto-idle turned off, engine began to lose power briefly with a slight Buzz (high pitch) when it ‘came back’ to full power — again while cruising, almost coasting — to keep pace and distance from the vehicle in front of me. My wife witnessed the event and made note of the time and speed. [XXX], 8:13pm — on [XXX] going through Jax on the way to the airport to pick up my wife. In the middle lane (second over from left lane) at ~60mph started to lose power in spite of my foot being on the gas. I kept the gas applied and the engine power came back. No buzz sound. At ~ 31,531 mile on the odometer. The truck has been back to the dealer 3 times and they cannot replicate the event.
