The 1998 Lumina is a decent W-body sedan undermined by catastrophic intake manifold gasket failures on the 3.1L V6 and transmission cooler line issues that can destroy the 4T60-E automatic. Budget for major repairs if buying high-mileage.
Intake Manifold Gasket Failure (3.1L V6)
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Coolant loss with no visible external leaks, White smoke from exhaust on cold start, Milky oil on dipstick or oil cap, Overheating and potential head gasket damage if ignored
Fix: Replace upper and lower intake gaskets with updated Fel-Pro PermaDryPlus kit, flush cooling system, change oil. 5-7 hours labor. If coolant mixed with oil for extended period, expect bearing damage requiring engine rebuild.
Estimated cost: $800-1,200
Transmission Oil Cooler Line Failure Leading to Trans Destruction
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Pink milkshake fluid in radiator or transmission, Transmission slipping or not engaging gears, Sudden transmission failure after coolant contamination, Coolant in trans pan or trans fluid in overflow bottle
Fix: Cooler lines rust through where they attach to radiator. Coolant enters trans, destroying clutches and valve body within miles. Requires transmission rebuild or replacement, radiator replacement, and flush of all cooling system. 12-16 hours labor total.
Estimated cost: $2,500-4,000
Lower Engine Failure (3.1L V6)
Occasional · high severity
Typical onset: 120,000-180,000 mi
Symptoms: Heavy knocking from bottom end, Metal shavings in oil, Loss of oil pressure, Catastrophic failure after intake gasket leak goes unnoticed
Fix: Rod bearings and main bearings wear prematurely, especially if coolant contaminated oil from intake gasket leak. Requires complete engine rebuild with pistons, rings, bearings, machine work. 18-24 hours labor, or short block swap at 14-18 hours.
Estimated cost: $3,000-5,500
Power Steering Rack Leaks and Failure
Common · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: Power steering fluid leaking on inner tie rod boots, Groaning or whining when turning at low speed, Stiff steering or complete loss of assist, Puddles under car on passenger side
Fix: Rack seals fail, leaking fluid. Remanufactured rack replacement with alignment. 3-4 hours labor. NHTSA recall addressed some early failures but not all units.
Estimated cost: $600-900
Engine and Transmission Mounts
Common · low severity
Typical onset: 80,000-120,000 mi
Symptoms: Clunking when shifting from park to drive, Excessive engine movement visible when revving, Vibration at idle in gear, Transmission thunk on acceleration
Fix: Upper engine mount and transmission mount fail from oil contamination and age. Replace both for best results. 2-3 hours labor combined.
Estimated cost: $300-500
Fuel Pump Failure
Occasional · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: No start with fuel gauge showing fuel, Intermittent stalling when hot, Whining noise from rear of car, Engine stumbling under load
Check for pink fluid in radiator AND transmission pan before buying — this is instant deal-breaker
Replace intake manifold gaskets with updated Fel-Pro kit preventively at 80,000 mi on 3.1L — cheaper than engine rebuild
Inspect transmission cooler lines for rust at radiator connection points every oil change after 70,000 mi
Use Dexcool-compatible coolant only and flush system every 30,000 mi — mixing coolants accelerates gasket failure
Budget $1,500-2,000 for deferred maintenance on any Lumina over 100,000 mi
Pass unless under 80,000 miles with documented intake gasket replacement and confirmed good transmission — too many expensive grenades waiting to detonate.

General Motors LLC (GM) is recalling certain model year 1998-1999 Chevrolet Lumina and Oldsmobile Intrigue, 1997-2004 Buick Regal and Pontiac Grand Prix, 2000-2004 Chevrolet Impala, and 1998-2004 Chevrolet Monte Carlo vehicles. The affected vehicles were previously repaired under recalls 08V-118, 09V-116, and 15V-201 to address the possibility that engine oil may drip onto the hot exhaust manifold.
Consequence: Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.
Remedy: The remedy applied under recalls 08V-118, 09V-116, and 15V-201 did not adequately remove the safety risk. Under the improved remedy, dealers will replace the engines front valve cover and gasket. Vehicles that are covered by recalls 08V-118, 09V-116, or 15V-201 that have not yet received the original remedy will instead receive the improved remedy under the original recall number. The recall began on February 19, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020, Buick customer service at 1-800-521-7300, Oldsmobile customer service at 1-800-442-6537 and Pontiac customer service at 1-800-458-8006. GM's number for this recall is 15757. Note: Until the improved remedy has been applied, owners are advised to park their vehicle outside since the fire risk exists even when the vehicle is unattended.
ENGINE AND ENGINE COOLING · 09V116000
2009-04-08 · EA07008
GENERAL MOTORS IS RECALLING 1,497,516 MY 1997-2003 BUICK REGAL, MY 1998-2003 CHEVROLET LUMINA, MONTE CARLO AND IMPALA, MY 1998-1999 OLDSMOBILE INTRIGUE, MY 1997-2003 PONTIAC GRAND PRIX VEHICLES EQUIPPED WITH A 3.8L V6 NATURALLY ASPIRATED ENGINE. SOME OF THESE VEHICLES HAVE A CONDITION IN WHICH DROPS OF ENGINE OIL MAY BE DEPOSITED ON THE EXHAUST MANIFOLD THROUGH HARD BRAKING.
Consequence: IF THE MANIFOLD IS HOT ENOUGH AND THE OIL RUNS BELOW THE HEAT SHIELD, IT MAY IGNITE INTO A SMALL FLAME AND MAY SPREAD TO THE PLASTIC SPARK PLUG WIRE CHANNEL AND BEYOND INCREASING THE RISK OF AN ENGINE COMPARTMENT FIRE.
Remedy: DEALERS WILL REPLACE THE ENGINES FRONT VALVE COVER AND FRONT-VALVE-COVER GASKET WITH NEW PARTS OF AN IMPROVED DESIGN AND REMOVE THE ENGINES PLASTIC COVER AND PLASTIC OIL-FILL-TUBE EXTENSION, FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN DURING MAY 2016. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, OLDSMOBILE AT 1-800-630-6537, AND PONTIAC AT 1-800-620-7668 OR HTTP://WWW.PONTIAC.COM OR HTTP:WWW.GMOWNERCENTER.COM.
CERTAIN DELPHI FUEL PRESSURE REGULATORS, P/NOS. FP10020-11B1, FP10026-11B1, AND FP10027-11B1, SOLD AFTER JANUARY 9, 2007, AS AFTERMARKET EQUIPMENT FOR VARIOUS PASSENGER VEHICLES LISTED ABOVE. THE UNIVERSAL PRESSURE REGULATORS (UPR) WERE PRODUCED WITHOUT AN O'RING AND RETAINER.
Consequence: FUEL MAY LEAK, POSSIBLY RESULTING IN A FIRE.
Remedy: DELPHI WILL NOTIFY OWNERS AND REPLACE THE UPR FREE OF CHARGE. THE RECALL BEGAN ON APRIL 23, 2007. OWNERS CAN CONTACT DELPHI AT 877-411-8770.
STEERING:RACK AND PINION · 03V527000
2003-12-11 · EA03019
CERTAIN PASSENGER VEHICLES HAVE LOWER PINION BEARINGS IN THE POWER RACK AND PINION ASSEMBLY IN WHICH THE RETAINER TABS WERE NOT CRIMPED PROPERLY. THESE RETAINERS COULD FAIL AND PERMIT THE BALL BEARINGS TO ESCAPE.
Consequence: IF THIS OCCURS, THE PINION SHAFT CAN BE FORCED UPWARD DURING LEFT TURNS AND BACK DOWN AS THE STEERING WHEEL IS MOVED BACK AND TO THE RIGHT. IF THE PINION SHAFT MOVES FURTHER, THE DRIVER WILL NEED TO EXERT MORE EFFORT TO TURN THE STEERING WHEEL, SIMILAR TO A VEHICLE WITHOUT POWER ASSISTED STEERING. IF THE PINION SHAFT MOVES EVEN FURTHER, THE DRIVER WILL REQUIRE MUCH HIGHER EFFORT TO TURN LEFT AND MAY NOT BE ABLE TO TURN THE WHEEL AS MUCH AS INTENDED. WITH THE MAXIMUM PINION SHAFT MOVEMENT, WHICH REQUIRES INTERNAL GEAR COMPONENT DAMAGE, THE DRIVER CAN ENCOUNTER HIGH RESISTANCE TO TURNING LEFT, FOLLOWED BY UNINTENDED POWER ASSIST TO THE RIGHT. IN ANY OF THESE CONDITIONS, A CRASH COULD OCCUR.
Remedy: DEALERS WILL INSTALL A NEW LOWER PINION BEARING UNLESS INSPECT OF THE EXISTING BEARING INDICATES THAT REPLACEMENT OF THE GEAR ASSEMBLY IS NECESSARY. OWNER NOTIFICATION BEGAN ON FEBRUARY 5, 2004. OWNERS SHOULD CONTACT BUICK AT 1-866-608-8080; CHEVROLET AT 1-800-630-2438; OLDSMOBILE AT 1-800-630-6537; OR PONTIAC AT 1-800-620-7668.
