2017 Volvo XC90 Electrical system Problems

“While driving with two young children in car, Volvo hood started to smoke. No warning lights or signals went off. We pulled over, turned engine off, removed kids from the car, and within a few minutes, the entire hood of the car was in flames. The car was completely destroyed, even though firefighters extinguished the fire. We have no information as to the cause of the fire - engine, electrical, etc - but the car only had 18,000 miles on it. Volvo had already replaced the rotors twice in two years - highly unusual - but otherwise we had no reason to suspect a problem. …”

“The Park Neutral Position (PNP) switch malfunctions. Yes Not a huge safety issue if you are parked in your driveway and cannot start the car. But if you are driving and the if you have the engine auto start/stop engaged the car will unexpectedly not restart and you have to play with the gear shifter to get it started to move out of an intersection or out of the way of traffic! This has happened several times with my wife and myself. I have not had it confirmed by a dealer or service center No No”

“I am reporting multiple critical component failures on my 2017 Volvo XC90, which I believe represent potential design or manufacturing defects related to vehicle safety and reliability. At approximately 93,000 miles, my Volvo XC90 experienced a battery failure, thermostat failure, which did not resolve the vehicle's engine issues. Subsequently, the dealership diagnosed a failed Engine Control Module (ECM), requiring complete replacement at a cost of over $5,000. The ECM is a critical motherboard component responsible for engine control and vehicle safety operations. …”

“For 5 months now, there has been leaking from the rear side of the intellisafe module located by the middle top of the windshield. I have taken the care to the dealership in multiple locations, they have not found the root cause. I have paid for multiple replacements of the rubber trim and cleaning of interior parts. The water leaks directly over the head unit, and I fear that might cause damage such as a electrical fire or replacement of parts that might become very costly. It happens while still in park and while driving.”

“While driving in hybrid mode while both the gasoline and electric motor are running or shifting back and forth, occasionally the electric motor will come on with a sharp, sometimes loud, metallic “bang”. The sound and feel appears to be coming from the rear. The last two times it happened, the car lunged forward on its own without additional pressure on the accelerator, and once over the past week it lunged forward near an intersection when lifting off the accelerator pedal and engaging the brake. The lunge almost caused me to rear end the car in front of me which I was not very close to. …”
