The 2002 Grand Am is a budget GM platform with well-documented weakness in the intake manifold gaskets (3.4L V6), lower intake manifold coolant crossover passages, and a transmission that doesn't tolerate deferred fluid changes. The 2.4L Twin Cam ('LD9') has a reputation for timing chain and head gasket failures when maintenance lapses.
Lower Intake Manifold Gasket Failure (3.4L V6)
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: External coolant leaks at front of engine, White smoke from exhaust on cold start, Overheating or coolant loss with no visible external leak, Rough idle or misfire from coolant entering cylinders
Fix: Replace upper and lower intake manifold gaskets, often includes coolant elbows and thermostat housing while apart. 6-8 hours labor. The plastic coolant passage in the lower manifold cracks; aftermarket aluminum replacements recommended.
Estimated cost: $800-1,400
4T40-E / 4T45-E Transmission Failure
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Harsh 1-2 or 2-3 shifts, Slipping under acceleration, especially when warm, No reverse or delayed engagement into gear, Burnt transmission fluid smell
Fix: These 4-speed automatics fail from worn clutch packs, valve body issues, and clogged filter/cooler. Rebuild runs 12-16 hours; used units are gamble. Cooler line corrosion often causes external leaks that go unnoticed until damage is done.
Estimated cost: $1,800-2,800
Timing Chain Stretch and Tensioner Failure (2.4L Twin Cam)
Occasional · high severity
Typical onset: 100,000-150,000 mi
Symptoms: Rattling noise from front of engine on cold start, Check Engine Light with cam/crank correlation codes (P0300 range), Loss of power or rough running, Engine won't start after sitting (jumped timing)
Fix: Replace timing chain, guides, tensioner, and often both camshaft position sensors. 8-10 hours labor. If chain jumped and valves contacted pistons, you're into head work or short block replacement.
Estimated cost: $1,200-2,000
Ignition Lock Cylinder and Passlock Security System Issues
Common · medium severity
Symptoms: Key won't turn or sticks in ignition, Security light stays on, engine cranks but won't start, Intermittent no-start requiring 10-minute wait with key on, Steering wheel locks and key won't release
Fix: GM's Passlock system fails when the resistor in the lock cylinder wears. Often requires lock cylinder replacement and relearn procedure (30 minutes with key on). Ignition switch itself also fails. 1.5-2.5 hours labor depending on column disassembly.
Estimated cost: $250-500
Front Lower Control Arm Bushings and Ball Joints
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunking over bumps from front end, Steering wander or loose feeling at highway speed, Inner tire wear, Creaking when turning at low speed
Fix: Lower control arm bushings rot and ball joints wear. Most shops replace entire control arms with bushings and ball joints pre-installed. 2-3 hours per side. Alignment required after.
Estimated cost: $400-700
Head Gasket Failure (2.4L Twin Cam)
Occasional · high severity
Typical onset: 90,000-130,000 mi
Symptoms: White smoke from exhaust, Coolant loss with no visible leak, Overheating under load, Oil appears milky or coolant has oil film
Fix: The 2.4L LD9 blows head gaskets between cylinders or into coolant passages. Head must be resurfaced, often needs new timing components while apart. 10-14 hours labor. Check for cracked head before reassembly.
Estimated cost: $1,400-2,200
ABS Module and Wheel Speed Sensor Corrosion
Occasional · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: ABS light on with codes for wheel speed sensors, ABS activates on dry pavement at low speed, Traction control light illuminated, Brake pedal pulses during normal stops
Fix: Front wheel speed sensors corrode at connector and fail. Rear sensors integrated into hub bearing assemblies. ABS module itself can fail internally. Sensor replacement 0.5-1 hour each; module replacement/programming 2-3 hours.
Estimated cost: $150-800
Owner tips
Change transmission fluid every 50,000 miles with GM Dexron VI—these 4-speeds don't tolerate neglect
Inspect intake manifold gaskets annually on 3.4L V6; early catch saves head gasket damage
On 2.4L engines, listen for timing chain rattle on cold starts after 80,000 miles—don't wait
Flush coolant with Dex-Cool compatible fluid every 3 years; plastic components crack when coolant degrades
The Passlock security bypass resistor trick works, but replacing the lock cylinder is the proper fix
Pass unless you're getting it for under $2,000 and can wrench yourself—the intake gaskets, transmission, and ignition system will nickel-and-dime you into a beater you can't sell.

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.
