2004 VOLVO S80 Power Train 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...

VEHICLE HAS BEEN HESITANT, SPUTTERING AND SURGING WHEN STOPPED OR INCREASING SPEED. WHEN STOPPED THE VEHICLE SURGES AND MOVES. THIS CAN BE VERY DANGEROUS, AS WE CAN HIT A VEHICLE IN FRONT OF US. THE ETM HAS BEEN CLEANED BY COLLINS AUTO IN SC. THEY TOLD US THAT IT NEEDED TO BE REPLACED WITH A FEW THOUSAND MILES. THERE IS BUILD UP IN THE THROTTLE BODY AND THIS IS DUE TO THE OIL CHANGE INTERVAL (7500 MILES) WHICH IS RECOMMENDED BY VOLVO. THIS IS A SAFETY ISSUE AND A PART DEFECT WHICH VOLVO SHOULD FIX AND REPLACE AT THEIR COST. *TR

TRANSMISSION HAS ERRATIC SHIFTING DOESN'T KNOW WHAT GEAR TO BE IN WAS TOLD BY VOLVO MECHANIC THAT TRANSMISSION WAS BROUGHT UP IN CLASS ACTION LAWSUIT BECAUSE TRANSMISSION IS NOT STRONG ENOUGH FOR CARS HORSE POWER. I WOULD LIKE TO HAVE IT FIXED. *TR
