What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 81 complaints with NHTSA since 2015. 43 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
While driving my nearly new 2026 Volvo EX90 at freeway speed, the vehicle unexpectedly began sounding warning tones and experienced a significant loss of propulsion/power. The vehicle was unable to maintain normal acceleration and freeway performance, creating a serious safety risk while I was traveling in active freeway traffic.
