The 2004 Grand Am suffers from notorious 3.4L V6 intake manifold gasket failures and four-speed automatic transmission issues that plague GM's N-body platform. The 2.2L Ecotec is more reliable but not immune to ignition system problems.
Lower Intake Manifold Gasket Failure (3.4L V6)
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Coolant loss with no visible leaks, White smoke from exhaust on startup, Milky oil on dipstick, Rough idle and misfires, Coolant smell in cabin
Fix: Replace lower intake manifold gaskets and upper plenum gaskets while it's apart. 6-8 hours labor. Often discover warped intake surfaces requiring machining. Strongly recommend pressure testing cooling system and replacing aging hoses during repair.
Estimated cost: $800-1,400
4T45-E Automatic Transmission Pressure Control Solenoid and Shift Solenoid Failure
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Harsh or delayed 1-2 shift, Slipping between gears, Check Engine light with P0758 or P1811 codes, Transmission stuck in 2nd or 3rd gear, Erratic shifting when cold
Fix: Replace pressure control solenoid and both shift solenoids, flush fluid, update valve body if worn. 4-6 hours labor. If delayed too long, internal clutch damage requires full rebuild at 12-16 hours labor.
Estimated cost: $600-1,200 for solenoids; $2,200-3,500 for rebuild
Ignition Lock Cylinder and Passlock Security System Failure
Common · medium severity
Symptoms: Security light flashing, no-start condition, Key won't turn in ignition, Car starts then dies after 2 seconds, Intermittent no-starts requiring 10-minute wait, Worn ignition cylinder with key stuck
Fix: Passlock sensor in lock cylinder fails or wiring breaks. Replace ignition lock cylinder assembly or perform Passlock relearn procedure (free but temporary). Some techs bypass system with resistor module. Cylinder replacement: 1.5 hours. This was subject to NHTSA recall for some VINs.
Estimated cost: $250-500 for cylinder replacement; $150-250 for bypass module
Front Lower Control Arm Bushing and Ball Joint Wear
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunking over bumps, Wandering steering or poor alignment retention, Inner tire edge wear, Steering wheel off-center after alignment, Looseness felt through steering wheel
Fix: Replace both lower control arms as assemblies (bushings not serviceable separately on most aftermarket parts). Ball joints integrated into arms. Alignment mandatory after replacement. 2.5-3 hours labor for both sides plus alignment.
Estimated cost: $450-750
Fuel Pressure Regulator Failure (3.4L V6)
Occasional · medium severity
Typical onset: 90,000-130,000 mi
Symptoms: Poor fuel economy suddenly, Black smoke from exhaust, Rough idle and hesitation, Gas smell from dipstick (leaking into oil), Hard starting when engine is hot
Fix: Pressure regulator diaphragm ruptures, dumping fuel into vacuum line and intake manifold. Replace regulator on fuel rail. 1.5 hours labor. Check for fuel contamination in oil; if present, change oil immediately after repair.
Estimated cost: $200-350
Cooling Fan Relay and Module Failure
Occasional · high severity
Typical onset: 80,000-120,000 mi
Symptoms: Overheating in traffic or at idle, Fans never turn on, Check Engine light with high coolant temp codes, AC blows warm at stops, Fans run constantly even when cold
Fix: Fan control module or relays fail, typically mounted near radiator and exposed to heat/moisture. Replace cooling fan control module and related relays. 1-1.5 hours labor. Verify wiring harness connections not corroded.
Estimated cost: $180-400
Window Regulator Failure
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Window drops into door, Grinding or clicking noise when operating window, Window moves slowly or unevenly, Window won't go up or down, Window falls down when door closes
Fix: Plastic regulator gears strip or cables break. Replace complete window regulator assembly with motor. 1.5-2 hours labor per door. Driver door fails most frequently due to use.
Estimated cost: $250-450 per door
Owner tips
Change transmission fluid every 50,000 miles with Dexron VI—this transmission is sensitive to dirty fluid and the factory 'lifetime' fill is nonsense
Inspect intake manifold gaskets on 3.4L V6 during every coolant service; catching seepage early prevents catastrophic coolant-in-oil contamination
Keep spare Passlock bypass instructions in glovebox—the 10-minute relearn procedure can get you home when sensor acts up
Use Dex-Cool compatible coolant only and flush every 5 years; mixing coolant types accelerates gasket degradation on these engines
Pass unless it's a 2.2L four-cylinder with documented transmission services—the 3.4L V6 is a ticking time bomb for expensive gasket and transmission repairs.

Every control module on the 1999-2005 Pontiac Grand Am — where it lives, replacement time, and what it takes to program a replacement. Modules marked dealer / factory tool won't work after a part swap alone — budget for programming.
Electric Power Steering Control Module (EPSCM)2.0 hr R&Rdealer / factory tool +0.5 hr▸ programming details
📍 On steering column or under instrument panel (2005 only, select models)
🔧 Tech 2 + SPS
⚠️ Late 2005 models only. VIN programming and steering angle sensor calibration required.
⚠️ Passlock II system. Relearn: key ON 10 min until security light off, OFF, repeat 3 times. Lock cylinder replacement requires BCM relearn.
Radio/Entertainment System (RAD)0.8 hr R&Rrelearn only +0.2 hr▸ programming details
📍 Center instrument panel
🔧 Theft-lock code entry or Tech 2
⚠️ Theft-lock code required. OnStar-equipped radios may require additional programming.

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.
