1998 Nissan Altima Engine

DURING CROSS-COUNTRY TRIP, VEHICLE BEGAN EMITTING METALLIC WHINING NOISE AND CLICKING IN ENGINE COMPARTMENT, NOT AUDIBLE FROM PASSENGER COMPARTMENT. WHEN I RETURNED HOME, I PERFORMED REGULAR TUNE-UP MAINTENANCE, CHECKED MY VALVE CLEARANCES AND TIMING ADJUSTMENTS. SHORTLY AFTER I STARTED MY VEHICLE AGAIN, MY LOWER TIMING CHAIN SNAPPED. AFTER A LENGTHY DISASSEMBLY, I DISCOVERED THAT A PIECE OF BLACK PLASTIC FROM A CHAIN GUIDE HAD BROKEN AWAY AND FUSED WITH THE CHAIN, CAUSING IT TO SEIZE AND BREAK. ALSO, THE LOWER CHAIN TENSIONER HAD BEEN COMPLETELY EATEN THROUGH BY THE CHAIN (NOT AS A RESULT OF POOR SERVICING; I CHANGED MY OIL EVERY 3000 MILES AND CHECKED/TOPPED IT OFF EVERY 2 WEEKS) THE INCIDENT CAUSED $600 IN PARTS DAMAGE, AND COULD EASILY HAVE COST $1500 IN LABOR AT A MECHANIC OR DEALERSHIP. THE CHAIN BREAKAGE DESTROYED MY OIL PUMP, CRANKSHAFT SPROCKET, LOWER CHAIN COVER, LOWER CHAIN TENSIONER, GUIDE (BEYOND ORIGINAL BREAKAGE) AND OIL PAN BAFFLE / SUMP TUBE. SINCE NISSAN HAD INITIATED A "TSB" BEFORE I EVER PURCHASED MY ALTIMA, NO COMPENSATION WAS EVEN CONSIDERED. OBVIOUSLY THE TSB PROCESS DOES NOT INCLUDE CHECKING VEHICLES AS THEY ARE BROUGHT IN FOR MAINTENANCE, AS I HAD REGULARLY HAD MY CAR SERVICED BY THE DEALERSHIP FOR A FULL YEAR POST-PURCHASE. I REPLACED THE DEFECTIVE CHAIN GUIDE WITH THE UPGRADED NISSAN COMPONENT, A METAL-BACKED GUIDE TRACK, AND SHALL SOON INSPECT MY TIMING AGAIN TO ENSURE THAT THE REPAIRS PERFORMED INDEED CORRECTED THE PROBLEM. TWO RECOMMENDATIONS: FIRST, THE TSB PROCESS NEEDS TO BE ADDRESSED, AS IT OBVIOUSLY DOES NOT EFFECTIVELY SAFEGUARD CONSUMERS AGAINST ENGINEERING BLUNDERS SUCH AS THIS; SECOND, AUTOMOTIVE MANUFACTURERS SHOULD BE HELD ACCOUNTABLE FOR QUALITY OF PRODUCT IN TERMS OF MECHANICAL SOUNDNESS AS WELL AS SAFETY. IF STATE CORPORATION COMMISSIONS CAN REGULATE SERVICE QUALITY AND PRICING FOR EVERY SERVICE AGENCY IN THEIR SPHERE, I THINK THE FEDERAL GOVERNMENT SHOULD HAVE THE SAME LEVERAGE OVER AUTOMOTIVE MANUFACTURERS. *JB

CONSUMER'S DAUGHTER EXPERIENCED NUMEROUS PROBLEMS WITH VEHICLE. IT INTERMITTENTLY STALLED. DEALER HAD VEHICLE ON 3 DIFFERENT DIAGNOSTIC MACHINES, AND IT JUST SHOWED THAT #4 CYLINDER NEEDED SERVICING. CONSUMER STATED THAT THIS HAD BEEN CHECKED A NUMBER OF TIMES AND STILL NOT REPAIRED.*AK

OIL SLUDGE IN ENGINE.

VEHICLE HAS NO POWER WHEN DRIVING, CANNOT ACCELERATE CORRECTLY OR SPEED UP WHEN CONSUMER WANTS TO. CONTACTED THREE DEALERSHIPS,AND ALL THREE THEY COULD NOT FIND CAUSE OF PROBLEM.*AK

ROTTEN EGG/SULFUR SMELL EMITTED FROM EXHAUST. FIRST SERVICE PERFORMED ON VEHICLE WAS TO REPLACE THE ON-BOARD COMPUTER. THIS DID NOT FIX THE PROBLEM. TOOK THE CAR TO ANOTHER DEALERSHIP AND THEY SAID THERE WASN'T A "FIX" AVAILABLE. A WORKAROUND TO AVOID THE SMELL IS TO BURN PREMIUM GASOLINE. PREMIUM GASOLINE DOES ELIMINATE THE ODOR, BUT THE MANUAL SAYS I NEED TO BURN GAS RATED AT 87 OCTANE. I SHOULDN'T HAVE TO BURN PREMIUM FUEL, WHICH IS MUCH MORE COSTLY, TO AVOID THIS PROBLEM. I BELIEVE THIS PROBLEM TO BE A ENGINEERING DEFECT, AND WANT THE PROBLEM RESOLVED. *AK

I OWN A 1998 NISSAN ALTIMA. ABOUT A WEEK AGO THERE WAS HEAVY FLOODING

PISTON FAILED. MJS

VENT CONTROL VALVE ASSEMBLY FAILURE.

ENGINE SKIPS WITH STRONG JERKING WHEN MODERATELY ACCELERATING.

OWNER STATES WHILE ACCELERATING ENGINE MISFIRES, CAUSING POOR PERFORMANCE OF VEHICLE. DEALER RAN DIAGNOSTIC TEST AND FOUND NO FAULT CODE. *AK
