While driving the van shuts off and looses all power to include power brakes and steering. Also the traction control light comes on. The following has been completed to fix the problem without the problem being resolved: replacement of battery and check of battery cables, recall complete of win module, replacement of O2 sensors and egr valve, and check of all fuses and wiring. After all of the aforementioned repairs the van still shuts off while driving. When the van shuts off the check engine light does not come on and there are no codes present for the mechanic to diagnose problem. This issue is an extreme safety issue and it appears there are numerous reports I have been able to locate on the internet. My wife will not drive the van not because of the problem. When the van shuts off you can place it in park and restart the van and continue to drive. The van has shut off on me while I have been driving it and there does not appear to be any indicator that it is going to shut down, ie stuttering or irregular operation. The speed that the issue has occurred ranges from 20 mph to 55 mph.
