2004 VOLVO S80 Steering Problems

PURCHASED A 2004 VOLVO S80 IN "MINT CONDITION" FROM A USED CAR DEALERSHIP (GOOD REPUTATION).THREE (3) MONTHS LATER THE TRANSMISSION STARTED THE FAMOUS VOLVO "SLIP, SLIDE, AWAY".. IT RIDES LIKE A ROCK, I FELL EVERY CRACK, GRAIN OF SAND IN THE ROAD. I REPLACED THE STRUTS, COIL SPRINGS, LOWER CONTROL ARMS AND OTHER SUSPENSIONS PARTS BUT TO NO AVAIL IMPROVED ITS CONDITION. EVERY WEEK OR SO I GET THE "STOP SAFELY COOLANT LEVEL LOW" WARNING ON MY DASH...KEEP IN MIND THE DEALERSHIP HAD NOTHING TO DO WITH THESE ISSUES SINCE THE CONDITIONS DIDN'T APPEARED UNTIL 3 MONTHS/50000 MILES AFTER THE PURCHASE. STEERING HAS SOME PLAY AND I'M CONTINUOUSLY RECOVERING THE DIRECTIONAL PATH SLIGHTLY. SHORTLY AFTER I PURCHASED THE VEHICLE I INSTALLED ALL NEW TIRES (MICHELINS) PURCHASED A LIFETIME WHEEL ALIGNMENT, WHICH WAS DONE DURING NEW TIRE INSTALL AND RECENTLY RE-CHECKED. I DO 90% OF THE WORK MYSELF; I'M AN ENGINEER...

THE LAST TIME I HAD THE CAR SERVICED THE REPRESENTATIVE AT THE DEALERSHIP SAID THAT THERE WERE ISSUES WITH THE POWER STEERING RESERVOIR. HE SAID THAT THEY HAD APPARENTLY MADE IT OF THE WRONG PLASTIC AND WHEN IT HEATS IT EXPANDS AND WILL LEAK FLUID, POSSIBLY FAILING. I DON'T KNOW WHAT THE RESULT WOULD BE WITH THE STEERING IF THIS HAPPENED. HE SAID THAT THE ITEM WOULD BE THE OWNERS RESPONSIBILITY TO REPLACE AND THEY WERE NOT RECALLING OR REPLACING THEM. *TR
