Approximately 59 days at the dealership across two extended service periods.
I continued documenting faults after the repair periods. As of September 21, my customer-care case remained without a proposed resolution.
After approximately 59 days at the dealership across two extended service periods, I requested a definitive resolution on July 28 and asked to be contacted directly by a Volvo Canada representative with authority to resolve the matter.
A formal demand to Volvo Car Canada Limited and Volvo Cars Saint-Léonard followed on August 24.
On September 18, Volvo Customer Care wrote that the file remained under review and that no update or final decision was yet available. As of September 21, no proposed resolution had been communicated.
“Electrical system temporarily limited.” “Reduced performance.” By April 13, I had reported a third occurrence in approximately three weeks.
The next day, I wrote that I had “almost had an accident on the highway.” I reported that driver-assistance functionality and one-pedal driving became unavailable as traffic slowed, requiring an avoidance manoeuvre.
The EX90 entered the dealership at 6,009 km. Diagnostics, technical escalation, software work and repeated road testing followed.
I reported that the problems had returned and were occurring on “almost every trip,” including unavailable adaptive cruise control, parking assistance and one-pedal driving.
The vehicle returned for a second extended service period. The investigation involved Volvo technical resources and further software interventions and testing.
Headlight, parking-assistance, parking-sensor and tire-pressure monitoring faults were documented, along with repeated warning-chime behaviour.
After the second extended service period, I wrote to the dealership’s management that I could no longer accept repeated repair attempts, requested a definitive resolution through replacement or repurchase, and asked to be contacted directly by a Volvo Canada representative with authority to resolve the matter.
With no resolution reached, I formally put Volvo Car Canada Limited and Volvo Cars Saint-Léonard on notice.
Volvo Customer Care wrote that the file remained under review, that the analysis was still active and that no update or final decision was yet available.

These are individual examples from the record, including electrical-system warnings and later malfunction alerts.
I was informed by the dealership that my EX90 received Volvo's upgraded core computer. Volvo describes the 2025 EX90 upgrade as a hardware-and-software change using dual NVIDIA DRIVE AGX Orin. I am not suggesting Volvo promised that upgrade would correct every issue my vehicle experienced. The narrower point is that I continued documenting faults afterward.

Some of the earlier and more serious symptoms improved. That fact belongs here. But after the core-computer upgrade, I continued documenting additional faults.
This video captures repeated warning chimes continuing without a corresponding problem message visible on the display. It is presented here as recorded — not as a diagnosis of the cause.
In 2025, another Montréal-area EX90 owner created MyVolvoEX90.com to document a different vehicle, owner, chronology and dispute. This site documents mine.
For context only: independent publications have covered the earlier Montréal case and have separately documented problems with EX90 vehicles they tested or owned. None of that is evidence about this vehicle.

“I just wanted to follow up regarding my EX90 case. Since providing the requested information to Volvo last week, I haven’t received any updates and was wondering if you had heard back from either Volvo Canada or the engineering team in Sweden.”
“According to Volvo, the issue with your vehicle is software-related. They have provided us with a special software update to load into your vehicle. They have also requested that we keep the car until the end of the week, as they plan to send a second software update this Friday.”
