2017 Volvo XC90 problems

“On 9/18/2026 at about 3:15 PM, the low coolant warning came on while I was driving in front of my child's school. Less than a minute later I pulled into the school pickup line, stopped, and turned the vehicle off. There was no smoke when I turned it off. After the engine was off, smoke began coming from the engine compartment, and within minutes the engine compartment was on fire. The fire occurred in a school pickup line surrounded by parents and children. An independent witness saw that the vehicle was off before any smoke appeared. The fire department and police responded. The engine compartment was destroyed and the vehicle is a total loss. Warning before failure: low coolant message, less than a minute before the vehicle was stopped. This vehicle has the B4204T27 (T6) engine. Volvo recalled 2016 XC90s with this engine (Recall 19V-308) because a cracked engine-side coolant bleeder hose could leak coolant onto the catalytic converter heat shield and cause a fire while the vehicle was stationary, with a low coolant warning as the sign. This 2017 was not included in that recall, but it gave the same warning and caught fire the same way while stationary. The…”

“Vehicle has exhibited lagging and stalling while driving in "Pure" (electric-only) mode since approximately April 2026, at approximately 85,000 miles, accompanied by an illuminated check engine light. This has occurred repeatedly at red lights, intersections, stop signs, and in stop-and-go traffic, creating a risk of sudden loss of propulsion in live traffic situations, including at intersections where an unexpected stall could result in a collision. The dealership (Volvo Cars of Fort Washington) has diagnosed this as originating from multiple hybrid drivetrain components over several repair visits: the High Voltage Coolant Heater (replaced per a referenced Volvo Technical Service Bulletin), the Inverter Electric Rear Axle Drive Module (IEM) — diagnostic data showed one internal transistor (phase W) reaching 135°C, a severe outlier compared to the other two phases reading approximately 25°C — the A/C refrigerant shutoff valve, and most recently the Electronic Rear Axle Drive (ERAD) transmission, where diagnostic monitoring showed the ERAD clutch slipping during test drives. Volvo's own internal case management system has classified this case as a "Repeat…”

“On thanksgiving day i drove to train station in the morning, and had no issue. After work i got in the car started to drive, i was going 25-35 miles per hour in the maplewood township, and i wanted to slow down just in case i dont see any kid or person at dark. I almost had no brake! I was so scared and i pushed th brake pedal so hard, i was very dangerous for the society at this moment. I just wish i was not on the highway going higher speed, or there were no people around! I really cannot trust this car anymore, i could have hit something!!!”

“The contact owns a 2017 Volvo XC90. The contact stated that after a rainstorm, there was water leaking from the rearview mirror, which leaked into the vehicle, causing the electrical system to fail. There was an abnormal sound of water swishing around inside the vehicle. The on-call warning and check engine warning lights were illuminated. The vehicle was taken to the local dealer, where it was diagnosed with a cracked sunroof cassette leak. The vehicle was not repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 147,000.”

“2017 Volvo XC90 T8 plug-in hybrid, approximately 81,000 miles, experienced intermittent hesitation/loss of propulsion when accelerating. When acceleration is requested, the vehicle can hesitate before power is delivered, creating a serious safety concern when entering, merging into, or crossing traffic because expected acceleration is not immediately available. Diagnostic testing identified faults in the IEM/ERAD system, including P286D00, Clutch A Engagement Time Performance/Too Slow, and P0A1B62, Drive Motor A Control Module, Algorithm Based Failure. The vehicle is currently being evaluated by an authorized Volvo dealer. I was advised that the high-voltage battery cells appear to be functioning properly and that the dealer is consulting Volvo technical support regarding the loss-of-acceleration condition. Volvo has issued Technical Journal guidance addressing ERAD clutch DTCs, including P286D00, on this generation of XC90. I am concerned that delayed or failed engagement of the ERAD clutch can cause an unexpected delay or loss of propulsion during acceleration. I am also aware of another NHTSA complaint involving a 2017 Volvo XC90 ERAD clutch failure, NHTSA…”

“Spark plugs, fuel injectors, cylinders and cylinder walls, pistons, oxygen sensor. Our safety was put at risk because the vehicles "reduced performance" was triggered and it affected the acceleration of the vehicle. The Volvo dealership was able to reproduce the issue because of the engine misfires.The only alert we received was the day prior our engine needed a liter of oil. We topped off the oil and that alert went away. The day we had the reduced performance we were alerted of that at the time on the highway. It's a little turtle icon. We were not able to accelerate efficiently and it was definitely unsafe to be driving but we had to get home.”
