2006 SUZUKI GRAND VITARA Engine Problems

DRIVER SIDE INTAKE MANIFOLD BUTTERFLY VALVE CAME LOOSE AND THE SCREWS WENT THROUGH THE ENGINE. RECENTLY THE BUTTERFLY ITSELF GOT STUCK AND LEANED OUT AND RUINED MY O2 SENSOR AND IDLE AIR CONTROLLER

I WAS ACCELERATING ONTO A SUPER HIGHWAY WHEN MY VEHICLE ENGINE LIGHT CAME ON AND THE ENGINE STARTED RUNNING ROUGH. WHEN I RETURNED HOME I PUT MY ENGINE SCAN ON THE COMPUTER AND IT STATED EGR VALVE....I BELIEVE IT MAY HAVE BEEN A P0401 CODE. I ORDERED A NEW EGR VALVE AND REPLACED IT ALONG WITH NUMEROUS GASKETS AND CLEANED EVERYTHING ACCORDING TO MY SERVICE MANUAL......WHICH BY THE WAY, IS THE $100 SHOP SERVICE MANUAL THE DEALERSHIP USES! IT CORRECTED THE PROBLEM FOR ABOUT 6 MONTHS TIME PERIOD AND THEN BEGAN ALL OVER AGAIN. I USE PREMIUM SHELL GASOLINE IN THE VEHICLE AND DO PREVENTATIVE MAINTENANCE ON A REGULAR BASIS AS DESCRIBED IN THE SERVICE MANUAL. I HAVE DONE SIGNIFICANT RESEARCH ONLINE AND HAVE FOUND NUMEROUS COMPLAINTS REGARDING THIS ISSUE HOWEVER, SUZUKI HAS NOT RESPONDED WITH A SOLUTION. I SEE FORD AND SOME OTHERS HAD THIS SIMILAR COMPLAINT AND REDESIGNED...

WHILE DRIVING, BELT TENSIONER SEIZED BREAKING BELT AND OVER HEATING CAR. BOTH BELT TENSIONERS HAVE BEEN REPLACED. THERE IS A RECALL FOR THE POWER STEERING/FAN TENSIONER. NOT FOR THE WATER PUMP/ALTERNATOR PULLEY/TENSIONER.

TL* THE CONTACT OWNS A 2006 SUZUKI GRAND VITARA. THE CONTACT STATED THAT THE VEHICLE FAILED TO START. ONCE THE VEHICLE WAS STARTED AFTER SEVERAL ATTEMPTS, THE CHECK ENGINE LIGHT WAS ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO DIAGNOSED THAT THE EGR VALVE WAS DEFECTIVE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 75,000 AND THE CURRENT MILEAGE WAS 88,600.
