2026 Volvo EX90 Electrical system Problems

“I purchased a brand-new 2026 Volvo EX90 just 4days ago from a volvo dealership . Yesterday, the vehicle’s software proximity logic malfunctioned and auto-locked the doors while my baby was strapped inside. My physical key card and my phone with the digital key were both inside the cabin. To make matters worse, when I tried to use the Volvo remote app to unlock it with a different phone, the app failed completely because the car was not “connected”. Volvo roadside assistance could not unlock the vehicle either. …”

“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. Earlier that day, the vehicle had displayed a warning stating “Charging system fault — book a service.” The vehicle’s GPS/location system was also malfunctioning. The GPS issue had occurred previously. …”

“Overall, we've been very happy with the EX90, but it's clear the vehicle is in desperate need of a comprehensive software update from Volvo. The issues we're experiencing don't appear to be hardware failures so much as recurring software-related problems. We've received intermittent propulsion system warnings, headlight system warnings, delayed accelerator response at times, and general electrical system sluggishness. The infotainment system can be slow to respond, and various vehicle functions occasionally lag or behave inconsistently before returning to normal. …”

“Software updates causing mechanical issues. Most recent software update blew the compressor and pump causing the AC to go out. According to volvo service department this is a widespread issue with their software updates for the EX90, who knows what other mechanical issues it may be causing. Safety issue as its 115 degrees outside and car only blows hot air.”
