Audited US model-year file

2004 CHEVROLET Impala

Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.

Model-year evidence is not a VIN check.

A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.

ENGINE AND ENGINE COOLING:ENGINE

Campaign 15V701000
Summary

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 engine’s 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.

ELECTRICAL SYSTEM:IGNITION

Campaign 14V400000
Summary

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.

Consequence

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.

Remedy

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.

They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports.

US-market boundary

Only NHTSA vPIC, NHTSA ODI complaints and investigations, NHTSA recalls and FuelEconomy.gov contribute to this vehicle claim. CPSC equipment notices are searched separately and never joined to vehicle fitment. UK MOT, Canadian, New Zealand and European records are not merged into this US claim.

06 · Research paths

Diagnose first. Confirm fitment.

These are transparent searches, not diagnoses or endorsed parts. Recall remedies come before purchases; exact part fitment requires VIN, trim, powertrain, production date and OE number.

Offers status: held

Awin US and R2 affiliate inventory are not published until a US programme, merchant and exact-fitment projection are approved. No offer currently has both merchant approval and exact vehicle fitment, so commercial links never count as evidence.
