2004 Oldsmobile Alero Recalls, Problems & Maintenance

The 2004 Oldsmobile Alero carries 2 open NHTSA recalls — most recently covering ignition and pressure relief devices. Owners report 6 recurring issue clusters, led by “Intermittent or inoperative turn signals and hazard lights.” Oldsmobile closed in 2004, so every one of these is at least two decades old. That flips the maintenance question from mileage to age. Rubber, coolant, and brake fluid time out even on a car that barely gets driven. Models from about 1996 on use GM's Oil Life System and Dex-Cool coolant. Older ones run on fixed intervals and green coolant, and the two must never be mixed. Mechanically most of the lineup is shared GM hardware, so parts stay cheap and easy to find. The 3800 V6 in the Eighty-Eight and Ninety-Eight is one of the most durable engines GM ever built. The 3.1 and 3.4 V6 family has a well-documented lower intake manifold gasket weakness, and the Aurora's V8 needs a shop that knows Northstar-family cooling systems.

ELECTRICAL SYSTEM:IGNITION

Campaign #14V400000 · Mar 7, 2014

Issue: This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) notified the agency on July 3, 2014, that they are recalling 5,877,718 model year 2000-2005 Chevrolet Impala and Monte Carlo, 1997-2003 Chevrolet Malibu, 2004-2005 Malibu Classic, 1999-2004 Oldsmobile Alero, 1998-2002 Oldsmobile Intrigue, 1999-2005 Pontiac Grand Am and 2004-2008 Pontiac Grand Prix vehicles. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.

Risk: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.

Fix: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 9, 2014. GM's number for this recall is 14350.

FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY:PRESSURE RELIEF DEVICES

Campaign #07E021000 · Dec 3, 2007

Issue: 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.

Risk: FUEL MAY LEAK, POSSIBLY RESULTING IN A FIRE.

Fix: 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.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter (Oil Life System)

Every 5,000 mi

On 1996 and later cars, change when the Oil Life System asks and at least once a year. Earlier cars used a fixed 3,000 mile interval. At this age a 5,000 mile ceiling is the safer read, because worn seals and a tired PCV system dirty the oil faster than the computer assumes.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 7,500 mi

Rotate every 7,500 miles. Check the DOT date code on the sidewall while you are under there. On a low-mileage car of this age, tires usually age out years before the tread wears out.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 7,500 mi

Inspect pads and rotors at every service, and ask specifically about the rubber hoses and steel lines. Line corrosion is a common failure on twenty-year-old cars that lived through road salt.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Brake Fluid

Every 24,000 mi

Replace every 2 years regardless of mileage. Brake fluid absorbs water from the air, and decades-old fluid is the quiet cause of soft pedals and stuck calipers on cars this old.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Automatic Transmission Fluid

Every 45,000 mi

Drain and fill every 45,000 miles using Dexron VI. If the fluid has never been changed on a high-mileage car, ask for two or three drain-and-fills spaced out rather than a high-pressure flush.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Spark Plugs

Every 100,000 mi

Platinum or iridium plugs run to 100,000 miles. On the 3800 and 3.4 V6, replace the plug wires and coil boots at the same time. After this many years the insulation is brittle and a failing wire reads like a bad coil.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Serpentine Belt & Tensioner

Every 60,000 mi

Replace the belt and the tensioner together once either shows cracking, glazing, or noise. A weak tensioner chews through a new belt in short order.

Estimated cost — typical U.S. ranges

Dealer

~$195–$235

Shop

~$135–$165

DIY

~$20–$50

DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.

Engine Air Filter

Every 30,000 mi

Replace every 30,000 miles. On most of the lineup this is a five minute job with a screwdriver.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Coolant Replacement

Every 100,000 mi

Treat this as a 5 year job, not a mileage job. Cars from about 1996 on use orange Dex-Cool, earlier ones use green. Never mix them. While the system is drained, have the shop look for seepage at the intake manifold and water pump, which is where these engines usually start weeping.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Battery & Charging System Test

Every 25,000 mi

Test the battery and alternator once a year. Aging body control modules on this era of GM can pull a small current after shutdown, and a strong battery hides that problem until the day it does not.

Estimated cost — typical U.S. ranges

Dealer

~$225–$390

Shop

~$160–$280

DIY

~$130–$250

Most auto-parts stores test and install batteries free with purchase. Skip the dealer markup.

Fatal crash history & reported problems

Occupant deaths in fatal crashes (FARS)

How the 139 occupant deaths break down

119

driver deaths

passenger deaths

139

occupant deaths

Crash years covered: 1990–2024 This model year first appears in 2003 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number

FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.

Why we show driver deaths too

Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.

Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.

IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.

Owner-reported problem signals

Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
