On the 1999-2005 Pontiac Grand Am, nHTSA campaign 14V400000 covers 1999-2005 Pontiac Grand Am vehicles for unintended ignition-key rotation out of RUN due to key-ring weight, road conditions or another jarring event. That can shut off the engine and prevent air-bag deployment in a crash. The campaign-wide 5,877,718 total covers multiple makes/models and is not a Grand Am owner or failure count. The exact remedy is key-ring/key-slot or key-head modification, not replacement of a worn ignition switch or lock cylinder.

Common Symptoms

  • VIN and campaign completion checked
  • key-ring load removed pending remedy
  • unintended RUN-position movement documented
  • separate switch/cylinder faults diagnosed independently

How to Fix

Until the campaign remedy is confirmed complete, remove other items and the key fob from the ignition-key ring as NHTSA directs. Check the VIN with NHTSA and GM and ask the dealer to confirm current remedy availability and any charge in 2026. Diagnose low-retention, starting or cylinder complaints separately. Do not buy an ignition switch, lock cylinder, key insert or cover from this page; campaign status, key configuration, failed path, part number and VIN fitment must be established first.

On the 1999-2005 Pontiac Grand Am, the Passlock theft-deterrent sensor built into the ignition lock cylinder wears and sends an unstable resistance signal to the body control module, which then interprets a legitimate key as a theft attempt. The system disables the fuel injectors, leaving the car cranking but not starting with the SECURITY light flashing, and the failure typically recurs and worsens until owners are stranded repeatedly. This is one of the most widely documented complaints on the 1999-2005 Grand Am, with a 23+ page Edmunds thread and a RepairPal-confirmed pattern failure.

This issue also affects: Chevrolet Corvette, Chevrolet Impala, GMC Yukon XL

Common Symptoms

  • Engine cranks but won't start
  • SECURITY light flashing or stuck on
  • Car starts after waiting 10 minutes with key on
  • Intermittent no-starts that become more frequent
  • Stalling shortly after start-up with security light on

How to Fix

Replace the ignition lock cylinder (which contains the Passlock sensor) and perform the 10-30 minute Passlock relearn procedure. As a stopgap, owners can do the 10-minute relearn (key on, wait for the security light to stop flashing) to start the car; many DIYers permanently bypass the sensor with an inline resistor on the Passlock signal wires.

On the 1999-2005 Pontiac Grand Am, cracked solder joints inside the hazard warning switch — through which all turn-signal current flows — cause the exterior turn signals and hazard lamps to work intermittently or fail completely. GM recalled 670,740 2000-2001 Grand Ams, Aleros, and Malibus (NHTSA campaign 03V327000, GM recall 03043) because a driver unable to signal turns risks a crash; a special policy (#04098) extended switch coverage to some other VINs. Owners of 1999 and 2002-2005 cars report the identical failure but were excluded from the recall.

Common Symptoms

  • Turn signals work intermittently or quit entirely
  • Signals come back after pressing the hazard button
  • Turn signal clicking continues after the lever cancels
  • Hazard flashers inoperative
  • Rapid or erratic flasher clicking from the column

How to Fix

Replace the hazard warning switch, which restores turn-signal operation. 2000-2001 cars may still qualify for free replacement under recall 03V327000; for other years it is an inexpensive part swap at the steering column. Toggling the hazard button often temporarily revives the signals, which confirms the diagnosis.

On the 1999-2005 Pontiac Grand Am, the in-tank fuel pump module fails in two documented ways: the pump itself quits, often without warning, causing the engine to die while driving or refuse to restart; and the fuel level sender card on the same module wears or becomes sulfur-contaminated, producing wildly inaccurate gas-gauge readings (GM addressed the gauge fault in TSB 01-06-04-008D, recommending sensor assembly replacement). NHTSA complaints record pumps failing at average mileages in the low 30,000s on some years, with a clogged fuel filter accelerating pump death.

Common Symptoms

  • Engine dies suddenly while driving with no warning
  • Cranks but won't start, no pump hum from the tank
  • Long cranking or several attempts needed to start
  • Fuel gauge reads empty when full or swings erratically
  • Whining noise from the rear near the fuel tank

How to Fix

Replace the fuel pump module (pump and level sender together) and always install a new fuel filter and strainer at the same time. On these cars the tank must be lowered to access the pump, so doing the complete module once avoids paying the labor twice.

On the 1999-2005 Pontiac Grand Am 3.4L LA1 V6, the 3.4L LA1 "3400 SFI" V6 in 1999-2005 Grand Am, Alero, Malibu, Venture, Montana, Aztek, Rendezvous, Impala has a notorious upper/lower intake gasket failure mode similar to the 3800 V6 but with a different gasket part. Coolant leaks externally (under the throttle body area), into the lifter valley, and/or onto the timing cover. Often co-fails with the plastic upper intake plenum cracking.

This issue also affects: Buick LeSabre, Buick Park Avenue, Buick Cascada

Common Symptoms

  • coolant under intake
  • coolant loss
  • rough idle
  • milky oil
  • overheating

How to Fix

Updated Fel-Pro MS98010T LIM gasket (metal-reinforced) plus the matching UIM gasket and plenum repair/replacement. $500-$900 at independent. Replace coolant temperature sensor and thermostat at the same time. Drain Dex-Cool, switch to G-05.

On the 1999-2005 Pontiac Grand Am, the sealed front hub bearing assemblies, which also house the ABS wheel-speed sensors, wear out prematurely and repeatedly on this generation — owners report replacing the same corner two or three times within a few years. As the bearing develops play, the integrated sensor signal drops out and the ABS, TRAC OFF, and SERVICE VEHICLE SOON lights come on, and a badly worn bearing left unaddressed risks wheel looseness. Flexing front sensor harness wires breaking at the strut are a common secondary trigger for the same warning lights.

This issue also affects: Chevrolet Avalanche, GMC Sierra 1500, GMC Yukon XL

Common Symptoms

  • Humming or growling that rises with road speed
  • Noise changes pitch when steering left or right
  • ABS, TRAC OFF, and Service Vehicle Soon lights on
  • Vibration or looseness felt in the steering wheel
  • Same bearing failing again within 1-3 years

How to Fix

Replace the complete hub/bearing assembly (the sensor is integral and not serviceable separately) with a quality unit, torqued to spec with a new axle nut. Inspect and repair the wheel-speed sensor harness where it flexes near the strut before condemning a second hub.

On the 1999-2005 Pontiac Grand Am, the cable-type window regulators use plastic pulleys, clips, and cable guides that become brittle with age and heat, then crack and let the cable jump or go slack. The motor usually still runs, but the glass drops into the door, jams crooked, or stops moving — frequently leaving the window stuck down. This is one of the most common ownership complaints on 1999-2005 Grand Ams, affecting both front doors on coupes and sedans.

Common Symptoms

  • Window falls down into the door and won't come back up
  • Motor runs or clicks but the glass doesn't move
  • Grinding or popping noises from inside the door
  • Window moves slowly or tilts crooked in the track
  • Window stuck partially open

How to Fix

Replace the window regulator, ideally as a combined regulator-and-motor assembly for a lasting repair; aftermarket assemblies are inexpensive. Re-taping or re-clipping the old plastic guides is only a temporary fix.

On the 1999-2005 Pontiac Grand Am, the undersized, thermally marginal factory front rotors on this generation develop excessive thickness variation (warping) very early — owners of new cars documented rotor turning or replacement at 8,000-25,000 miles, and the problem repeats after machining because the thinner rotor warps even faster. The result is steering-wheel shake and brake-pedal pulsation under moderate-to-hard braking that returns every set of pads. The issue was widely reported across the 1999-2005 model run.

Common Symptoms

  • Steering wheel shakes when braking from highway speed
  • Brake pedal pulsates underfoot
  • Vibration worsens with moderate to hard braking
  • Brake shudder returns within 10,000-20,000 miles of service
  • Front-end shimmy felt mainly during braking, not cruising

How to Fix

Replace (don't machine) the front rotors with quality aftermarket rotors and fresh pads, clean the hub face, and torque the lug nuts evenly to spec. Upgraded aftermarket rotors hold up noticeably better than the original-spec parts.

ELECTRICAL SYSTEM:IGNITION

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.
