The following is a list of electrical channels that have been used to trigger the engine failure: brakes, indicator lights (right or left) heated seats (x2) front windshield defrost multiple S60 model owners have reported having experienced this same engine failure which cannot be detected by the manufactures diagnostics test.

I have a 2004 Volvo s-60 with approximately 75,000 miles on it. In the past 6 weeks, the car engine has completely died three separate times - without warning. The emergency hazard light still worked, the fan still blows (no a/c, just the fan), but otherwise there is no power, no brakes, no steering, no warning lights whatsoever. Each time this has happened, it has been when I am driving between 40-55mph. When the car coasts to a stop and I am able to re-start it, it starts without a problem. My Volvo dealership says they see no evidence of problem on the car's computer system, and the car did not die when they test drove it, therefore they say they cannot diagnose the problem - and that without a diagnosis, they cannot repair it. They also claim that Volvo's database has no related vehicle or parts recall on my particular VIN/vehicle. However, with absolutely no warning of when the engine failure will occur, and with no control over steering or braking, this is a very dangerous situation that Volvo so far cannot address unless the engine failure happens right in front of them. With no way of controlling when the car will die, this is obviously not a satisfactory resolution for the safety of myself or for other drivers.
