Headlight Switch Problems of Volvo XC90

2004 Volvo Xc90 sudden engine stall with lose of headlights: I was traveling on the interstate at night with the cruise set at 75 mph when suddenly it was like someone turned the ignition key to off for about 3 seconds, and then turned the key back on without restarting the engine. With all the warning lamps illuminated, and the engine at a stall I pulled into the emergency lane, and stopped. I then shifted to park and attempted to start the vehicle, where it took several attempts to start. The headlights did not stop working while pulling over, and when I stopped I switched the lights off before I restarted the engine. The first thing at mind was a fuel pump that was starting to act up. After restarting I revved the engine up a few quick times (to clear the engines throat). I then got back on the interstate accelerating to 75 mph , but doing so manually this time(no cruise control). About 10 min had passed when suddenly the engine started losing power as I was having to press the accelerator harder to maintain speed. While still coasting at 65 mph or so I placed the transmission into neutral, and attempted to restart the engine, when I turned the key to the start position I lost all the lights, I quickly released the key to the on position, and the lights remained off. I quickly pulled to the emergency lane and used the force to avoid the guardrail and the ditch. All the warning light were illuminated, and the engine was at a stall. I then turned the ignition key off and then back on, and that restored the headlights. It took 5-8 attempts to restart the engine, and again I'm thinking fuel pump acting up. Each time I attempted to restart the engine it would spit and sputter like if the fuel pump were only delivering half the pressure needed for the fuel injectors. After the engine restarted I made it home, and the problem has not arisen since,.

I switched from headlights on to daylight driving lights on. I received a "bulb failure" for the daylight driving lights. I switched back to headlights. I received a "bulb failure" for the hids. I have verified that the fuses are good, and that there are now no working headlights on the car. Had this happened at night it could have been bad, very bad. Thank god it happened during a sunny day and that the teen driver wasn't behind the wheel.

2006 Volvo Xc90 t6 awd April 21, 2013 approx 8:30 pm driving at approx 8:30 pm, traveling at about 55 miles per hour, remote 2-lane highway (us191, eastern arizona) on twisty mountainous road, switched from high-beam to low-beams to accommodate oncoming vehicle approaching around a bend. A moment or two after switching to low beams, the Volvo's headlights lights flickered and went out all-together. Error message reading something to the effect of "low beam bulb failure" appeared on message screen. High-beams didn't appear to be operable either. I activated fog lamps and proceeded cautiously to destination (approx 25 miles away). Approx 15 miles from that point, I was pulled over by dps patrol advising I had no headlights. . . And that my license plate light was also not operating. The next morning, investigated further, discovered there were no issues with the headlight bulbs (low beam and high beam) or with license plate bulbs specifically (they were not burnt out), nor were there any issues with any blown fuses related to those exterior lights. I did discover that the drl (daytime running lights) were still operating as normal (which utilize the same bulb as the low headlights) confirming that there were no issues with those bulbs. All research since this event is pointing me to conclusion that this monumentally unsafe condition was caused by a bad/faulty cem design by Volvo (online research, speaking with Volvo mechanics and reviewing similar NHTSA complaints). There is no preventative maintenance that I could have done to prevent this from happening. This is not an owner maintenance issue, this is a design or materials issue. Volvo should be required to recall & repair to prevent this safety issue. I request NHTSA open (re-open?) investigation into this issue, as this very dangerous safety issue that needs addressing before much worse consequences result.
