Chev uplander 2007 and stranded multiple problems & messages Lost power steering Charging system failure message Change oil soon Turn AC off to preserve engine(AC wasn't on Gage registered maximum 6

Have the vehicle check for DTC'S - diagnostic trouble codes . Most all parts stores will do it free of charge . They will also do charging system testing .

How hard, if it's as if you have lost power steering. Check to see if the power steering belt is still there or slipping, power steering fluid is low or empty. (Is cap leaking or leak in hose)
if it still has has power assist and has just gotten harder is it all the time or just low idol, need a better description of what is happening , I hope this helps

it wont go away because their is a mechanical problem and or problem with oil change [ not enough oil wrong filter etc ] will need to have vehicle scanned for the fault code to determine the problem most auto stores offer this service for free

The "Change Oil" message displayed on your Chevrolet Silverado's gauge cluster is part of the Oil Life Monitoring System, standard on many GM (General Motors) vehicles. The message appears when it's time for an oil-change; the interval is based on your driving habits (for example, it may appear more frequently if you engage in a lot of stop-and-go traffic). Once you change your Chevy's oil, the message will not disappear; the system must be reset. The process is a bit different between Chevy Silverado models.

your idle air controller valve on the throttle body may be no good.if the idle speed drops too low,the alternator will have no output,and the steering rack which on the uplander i believe is electric like the cobalt,will not put out enough drive.if you shut off the vehicle,but leave the ignition on,and it has an electric rack,the steering should still work.if it doesnt it is hydraulic assist.if the idle speed goes to say 400 rpm,the power steering will not work .when this happens,check the tachometer what the rpm is...
