On 25th August, while driving my brand-new leased 2026 Volvo XC90 B6 (approximately 4,930 miles) at highway speeds of 60 to 65 mph on the interstate i80 NJ at night, the vehicle suffered a sudden, catastrophic loss of propulsion. The engine abruptly shut off without warning, causing the vehicle to immediately and rapidly lose speed.Traffic conditions were active, and a semi-truck was directly behind my vehicle. Due to the sudden deceleration and total loss of engine power, I narrowly missed a life-threatening, high-speed collision with the semi-truck. I managed to safely maneuver the unpowered vehicle across active lanes to the right shoulder.Once on the shoulder, the "Check Engine" light and a "Turtle" icon (reduced engine performance indicator) appeared on the digital dashboard. The vehicle completely refused to restart. Eventually when Roadside Assistance arrived and attempted to add fuel to the tank to rule out a low fuel (odometer said 1/4 tank re ~65miles to empty), but the vehicle still failed to start or turn over. The car was flatbed-towed to an authorized Volvo dealership at 3:00 AM, where it currently sits. This is the second major electrical failure this new vehicle has suffered in less than 3 months, following a previous incident where the battery abruptly died. A complete powertrain and engine shutdown at highway speeds presents an extreme, life-threatening safety defect that requires immediate federal investigation

Was driving on a freeway when tire pressure light came on and tire blew out a few minutes later. I could not see the events of what happened behind me, but when my tire blew I got over to the right shoulder as safely as possible to move out of the way of oncoming traffic on the freeway. This incident occurred after only 2 months of driving car (3,000 miles on the car).

While my own 2026 Volvo EX90 was in for warranty repair (air conditioning compressor failure, believed related to a recent over-the-air software update), the dealership provided me with a loaner vehicle that exhibits its own intermittent climate control malfunction: the air conditioning shuts off completely when the vehicle comes to a stop and resumes when the vehicle is put back in motion. This occurs consistently and unpredictably during normal driving. I am filing this as a related report to a prior NHTSA complaint I submitted regarding my own EX90's air conditioning/compressor failure, as this may indicate a broader pattern with climate control systems on this platform rather than an isolated defect.
