2025 VOLVO EX90 Electrical System Problems

While driving on I-5 north by Castaic (exit 176A) the car displayed "electric system temporarily limited" then "critical electric fault" at which time it rapidly decelerated while on the freeway. The hazard lights were pressed but did not work. There was no shoulder and cars nearly rear ended our vehicle, with our family of 4 (including 2 kids) inside. We were able to navigate the vehicle to a small shoulder at the freeway exit and called CHP for support to ensure our safety while we seemed roadside assistance. Volvo roadside assistance contacted a tow truck and walked us through a "hard reset" of the vehicle. After about 15 minutes we were able to drive the car with a CHP escort off the freeway ramp to a nearby parking lot. The "electrical system temporarily limited" fault remained. Our car was towed to the nearest dealership where the fault was observed. At this point (8 calendar days later) no fix has been identified. This vehicle has had repeated electrical system faults since we leased in on 9/5/25 and has been serviced 3 previous times. This was the first time it stopped while driving.

I have been in multiple situation where my car is unable to charge from my home charger, and the issue is always same which is the need of GHCA replacement. Right now, GHCA for EX90 is in national back order with unknown ETA

Please note this is an all electric SUV. On Saturday 6th December, I unplugged the car from the A/C charger after it had finished charging to 90% in my garage and there was a very loud bang heard from under the car. The dashboard then reported there is a fault with the car and it cannot charge. Took the car to the dealer same day and they suspected it was a failed GHCA part (AC to DC converter). They ordered a replacement and fitted it on 20th December but the car still will not charge on A/C. It still charges on DC and the dealer is using that to keep it powered. I received a call from the dealer today (1/2/26) to say that Volvo corporate needs to perform a detailed investigation as to what has caused the car to stop charging on AC. The dealer will not let me have the car back as they are concerned about the safety of the car and have been without it for approaching one month now. With that in mind and the many reports on social media of similar failures as well as multiple months of having faulty cars, it appears this is a major problem that should be subject to a recall.

While driving, my car suddenly displayed the "Driver Support System Fault" icon (Picture 1). At that time, the only issue was the fault icon. I still had full navigation, lane departure warning and 360 camera functionality when I backed into my parking spot. The car was locked with my key card. I returned to 15 to 20 minutes later. The Driver Support System Fault Icon was lit in addition to the lane departure unavailability icon (Picture 2). The following functions and/or features did not work: - Lane Departure - 360 Camera - Front Camera - Tracking Lines for the Rear Camera - Park Sensor audible alerts (Forward or Backup) - Ambient Temperature (Reads "0 degrees Celsius") - Odometer in the central stack (Reads "-- km") - HVAC Functionality - Heated Seats - Heated Steering Wheel - Bluetooth - Wi-Fi - Google Assistant - Navigation, including map being frozen in one position - Glovebox access - Connectivity with Internet or Volvo App - Volume control for the radio did not function. - 4-way hazard button greyed out and non-functional on center stack Attempted reset/reboot of the Infotainment System did not resolve the issue and the car was taken to the local Volvo dealer. Summary of Pictures attached: Pic 3 - Quick Controls - Shows glove box, 4-way hazard icon and other control icons greyed out Pic 4 - Status - States "Everything is OK", but tire pressure button is not available and Total distance reads "--km". Additionally, as shown in Picture 3, the 4-way hazard icon is greyed out. Pic 5 - Similar shot as Picture 2 - Shows Driver Support System Fault and no Lane Departure Pic 6 - Car is in reverse. Shows rear back up camera without guidance lines. Does not show 360 camera. Pic 7 - HVAC Climate is off and cannot turn on. All controls were greyed out. I pressed "Manual" and "Auto" with no change. Pic 8 - Heated seats and heated steering wheel would not turn on even when I pressed the buttons.

One pedal driving randomly turns off when starting the vehicle. This is a safety issue because we often don't notice its off until we're attempting to stop and taking your foot off the accelerator does not result in braking as expected.

The screen behind the steering wheel, which provides the car's speed, driver assist, warning lights, turn signals, and other driving information suddenly went blank. I was grateful that I was close to home and no longer on the interstate highway I had just exited. I drove home, reset the car, and the screen was back on. I was lucky. I could have been at the beginning on my drive, over a hundred miles from home and unable to easily exit the highway. The car is being towed today back to the dealer, again. This happened without warning. I was driving and the whole screen just went black.

Drivers display with vehicle speed and ADAS state goes blank while driving resulting in inability to see current speed or ADAS speed set point. After rebooting the system as previously advised by Volvo, the ADAS speed set point showed "00" while maintaining a speed of 70mph

Lane keeping sensors periodically fault and Volvo's solution is to reboot the vehicle

Vehicle: 2024 Volvo EX90 VIN: [XXX] While driving on the highway, the entire digital instrument cluster and infotainment screen went completely black without warning. I could not see my speed, gear indicator, or use turn signals. This created an immediate and dangerous safety hazard, especially at high speed. The issue has occurred more than once, and despite taking the vehicle to the dealership, it has not been permanently resolved. I have filed a California Lemon Law claim with Volvo, and while Volvo acknowledged the defect and promised a buyback on March 18, 2025, they have failed to follow through or provide a resolution for over two weeks. I am submitting this complaint because the vehicle presents an active safety risk to myself and others, and I am concerned that this defect could result in a serious accident or injury if not addressed immediately. I also have video evidence of the blackout event. I am requesting that NHTSA open an investigation into this issue and hold the manufacturer accountable for failing to address a known safety defect in a timely manner.

Our EX90 will not charge with our installed Tesla Universal L2 charger. When the charger is connected to the vehicle, it appears to start charging for 2-3 minutes, then I get a Charging Fault, the charger tries to re-initialize, and this loop continues, all while not charging the car. While the car is attempting to charge the EX90 dash shows Power at 1KW or less and the Amps only get up to 4 max, but mainly stay around 1. We contacted Tesla and they said it could be a bad adapter, so they sent a replacement unit. After this unit was installed, the same issues with charging the EX90 continues. We have charged other electric cars with the Tesla charger and it works perfectly, which leads me to believe this is a Volvo issue.

I was on the 101 freeway on January 20, 2025. I was driving on the far left lane, driving 72-65 miles an hour. The 2025 Volvo EX90 suddenly wouldn't accelerate more than 36 mph. A turtle error came on the screen. "Driving Performance Reduced Drive with Caution Book a Service" message displayed. Due to the car suddenly slowing down, we almost were read ended by a truck. I have kids in the car. This car had multiple faults. I had the car serviced on 01/20/25 and received it back from the dealer on 01/28/25. After, receiving the car two days later, now the SOS fault System light turned on, and now the Air Bag Fault Light is on. I do have a video of the incident on the freeway when the car started slowing down and the error messages.

On Saturday, [XXX], I drove from Woodbridge, VA to Fairfax, VA without any issues or error messages. Car was parked and locked for approximately 2 1/4 hours. When I came back out to the car and opened the door, the display behind the steering wheel stated "System communication fault. Pilot Assist deactivated. Find a place to stop and select P to park. When parked, the system will reset." I followed the directions as specified in my parking spot without any change. I moved the car to another location in the parking lot and repeated the process as directed without any change. I then got out of the car, locked the car, walked away from the car so that I was well out of range of the car, and then came back to the car. Despite these efforts, when I unlocked the car with my Key Tag and got back in, I was not able to get the message to clear. This resulted in the following issues: (a) No speedometer on the display or in the HUD; (b) No green graphic for the turn signals to indicate that they were working; (c) No display of information concerning cruise control, headlight function or windshield wiper settings; (d) Speed limit sign reading in HUD was stuck on 25 mph even though I was driving on roads with higher speed limits (e.g., [XXX] - 45 mph and [XXX] - 55 mph); and (e) Center stack stated "1 serious issue detected - Emergency Call System fault - book a service". The car was driven this way from Fairfax, VA to the Service Department of the Volvo dealership with no change and when I left, the cluster behind the steering wheel and the center stack were still in the same condition.
