Driving on highway approx 65 mph in rain. Sudden loss of power steering, message on dashboard indicating check charging system, then hill assist failure, then warning message that all accessory power was disabled to conserve power. Then all lights on dashboard lit up. Loss of power steering in rain on highway almost caused vehicle to lose control and be involved in multiple car accident. Serpentine belt was found to be in proper condition, and was able to drive home alternate route along 35mph roads. No further problems aside from occasional squeak under acceleration. Immediately followed up with service call, serpentine bell was in good condition, but belt tensioner spring had failed. Vehicle has only 57,000 miles. Seems excessively early for this type of part to fail.
