TL*THE CONTACT OWNS A 1999 OLDSMOBILE 88. WHILE DRIVING 10 MPH, THE STEERING BECAME VERY LOOSE AND THE CONTACT LOST CONTROL. HE MANAGED TO PULL THE VEHICLE OVER TO THE SIDE OF THE ROAD. THERE WERE NO WARNINGS PRIOR TO THE FAILURE. THE VEHICLE WAS TOWED TO A LOCAL REPAIR SHOP AND THE MECHANIC STATED THAT THERE WAS A SHEARED BOLT BETWEEN THE RACK AND PINION AND THE SUBFRAME. THE VEHICLE IS CURRENTLY BEING REPAIRED AT THE COST OF $750. THE CONTACT IS IN THE PROCESS OF NOTIFYING THE MANUFACTURER. THE FAILURE AND CURRENT MILEAGES WERE 130,000.

I BROUGHT MY CAR IN TO THE DEALERSHIP FOR AN OIL LEAK AND WHILE THERE THE MECHANIC ALSO CHECKED THE COOLANT LEVEL. IT WAS LOW. HE PRESSURE TESTED THE SYSTEM AND FOUND THE COOLANT CAP TO BE NOT SEALING PROPERLY. I PAID FOR MY REPAIRS AND LEFT. THE NEXT MORNING THE CHECK ENGINE LIGHT CAME ON. I BROUGHT THE CAR BACK TO THE DEALERSHIP. THEY FOUND THE ENGINE WAS MISFIRING. THEY CHECKED THE COOLANT LEVEL AGAIN AND IT WAS DRY. THE INTAKE MANIFOLD HAD MELTED AND COOLANT HAD LEAKED INTO THE ENGINE AND WAS CONSUMED BY THE ENGINE. NOW I NEED A NEW INTAKE MANIFOLD, GASKETS, SPARK PLUGS, WIRES, AND AN OIL CHANGE TO THE TUNE OF $800+. I HAVE SEARCHED ON THE INTERNET AND FOUND MANY SIMILAR COMPLAINTS. WHY DOES GM NOT DO ANYTHING. THE INTAKE MANIFOLD WAS PLASTIC. PLASTIC DOES NOT BELONG IN AN ENGINE. I HOPE YOU MAKE THEM RECALL THIS. *TR

WAS DRIVING MY 99 OLDS 88 UP A HILL IN TN AND IT STARTED TO SHAKE AND LOSE POWER. THE CHECK ENGINE LIGHT CAME HOME AND THE ENGINE WAS EXCESSIVELY HOT. ALL OF THE RADIATOR WOULD TAKE THE FLUID BUT NOTHING WOULD LEAK OUT. I PULLED THE CAR OVER AND WAITED FOR IT TO COOL DOWN BUT THEN AFTER THE 3RD TIME TRYING TO START IT, IT MADE A CLUNK NOISE AND WOULDN'T START ANY MORE. I WAS TOLD IT WAS A HYDRAULIC LOCK UP. CAR SAT FOR 5 MONTHS AND FINALLY GOT THE MONEY TO HAVE IT TOWED TO A COLLISION CENTER TO HAVE IT LOOKED AT. I WISH TO BE REIMBURSED AFTER IT IS FIXED. *JB

I EXPERIENCED STALLS AND POWER SURGES. DEALER REPLACED FUEL PRESSURE REGULATOR DUE TO RECALL. SIX MONTHS LATER CAR REACHED EXTREMELY HIGH TEMPERATURE THEN DIED. MECHANIC REPLACED CRACKED PLENUM. GASKETS, PIPES, ASSEMBLY, SEALS AND SENSOR RESULTING IN $1234 REPAIR BILL. CONTACTED GM AND GOT FULL REIMBURSEMENT AS VEHICLE HAS ONLY 37,000 MILES ON ENGINE. LESS THAN 250 MILES AFTER REPAIR, ENGINE PRODUCES LOUD KNOCKING NOISE AND LOSS OF POWER WHILE DRIVING HOME FROM TOWN 90 MILES FROM HOME ON JULY 4TH. MECHANIC SAYS ONE OF THE PISTONS/RODS IS BAD, MORE THEN LIKELY A RESULT OF THE PREVIOUS PROBLEMS. HAVE NOT BEEN SUCCESSFUL IN REACHING THE EXTREMELY HELPFUL CUSTOMER SERVICE REPRESENTATIVE I WAS DEALING WITH FROM GM BUT I WILL NOT DROP THIS! LAST QUOTE FOR CURRENT REPAIR WAS $1100. *JB

204V090000 · Fuel System, Gasoline:delivery
Feb 24, 2004
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 3800 V6 (L36) ENGINES AND CERTAIN DELPHI FUEL PRESSURE REGULATORS, THE REGULATORS HAVE A MUCH HIGHER THAN USUAL RATE OF FUEL LEAKS. A LEAK CAN ALLOW FUEL TO ENTER THE INTAKE MANIFOLD THROUGH A VACUUM LINE. IF THE ENGINE DOES NOT START WHEN CRANKED, THE FUEL FROM THE LEAKING REGULATOR AND A MISTIMED SPARK CAN CAUSE A BACKFIRE.
Consequence & remedy
Consequence: THE BACKFIRE CAN RUPTURE THE INTAKE MANIFOLD. THE RUPTURE OF THE INTAKE MANIFOLD CAN DISPLACE A FUEL LINE, PULLING AN INJECTOR OUT OF PLACE, AND CAUSING A FUEL LEAK AND POSSIBLE FIRE.
Remedy: DEALERS WILL INSTALL NEW FUEL PRESSURE REGULATORS WITH IMPROVED DIAPHRAGMS. THE RECALL WILL BE CONDUCTED IN PHASED MAILINGS. PHASE 1 BEGAN ON JUNE 30, 2004, AND PHASE 2 BEGAN ON SEPTEMBER 30, 2004. OWNERS SHOULD CONTACT BUICK AT 1-866-608-8080, OLDSMOBILE AT 1-800-630-6537, OR PONTIAC AT 1-800-620-7668.
99V089000 · Power Train:automatic Transmission
Apr 26, 1999
VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH 4T65E AUTOMATIC TRANSMISSIONS. THESE VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FMVSS NO. 102, "TRANSMISSION SHIFT LEVER SEQUENCE." A RETAINING CLIP, WHICH SECURES THE MANUAL VALVE TO THE LINKAGE OF THE TRANSMISSION DETENT LEVER, CAN BECOME LOOSE UNDER A COMBINATION OF POSSIBLE DRIVER SHIFTING MANEUVERS AND ALLOW THE LINK TO BECOME DISCONNECTED FROM THE MANUAL VALVE.
Consequence & remedy
Consequence: IF THE LINK DISCONNECTS, THE DRIVER'S INDICATED PRNDL STATE MAY DIFFER FROM THE HYDRAULIC STATE OF THE TRANSMISSION. IF THE DRIVER SELECTS 'DRIVE' AND THE TRANSMISSION IS ACTUALLY IN 'REVERSE', A VEHICLE CRASH COULD OCCUR.
Remedy: DEALERS WILL REPLACE THE MANUAL VALVE/LINK ASSEMBLY WITH A REPLACEMENT MANUAL VALVE/LINK KIT, FEATURING A SPRING-TYPE FASTENER.
