The 2001 Impala is a comfortable W-body sedan undermined by chronic transmission cooler failures that destroy the 4T65-E transmission, plus widespread intake manifold gasket leaks on the 3.8L and upper engine failures on both V6 options at higher mileage.
Transmission Oil Cooler Failure Leading to Transmission Destruction
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Pink or strawberry milkshake-colored fluid in radiator or overflow bottle, Transmission slipping, delayed engagement, or complete failure, Overheating transmission, burnt smell, Check engine light with transmission codes
Fix: The internal radiator transmission cooler fails and allows coolant to mix with ATF, destroying clutches and internals within days or weeks. Requires transmission rebuild or replacement PLUS new radiator with external cooler added. Preventive radiator replacement at 100k saves the transmission. 8-12 hours labor for both jobs combined.
Estimated cost: $2,200-3,800
Intake Manifold Gasket Failure (3.8L Series II Engine)
Common · medium severity
Typical onset: 60,000-120,000 mi
Symptoms: Coolant seeping externally around intake manifold, visible green stains, Slow coolant loss, need to top off frequently, Rough idle or misfire if coolant enters cylinders (less common), Sweet coolant smell from engine bay
Fix: The plastic composite intake manifold develops leaks at the gasket surfaces, primarily at the coolant passages. Requires removing intake, new Fel-Pro or updated gasket set, and addressing EGR valve condition while apart. 4-6 hours labor. Use updated metal gasket design, not OEM plastic.
Estimated cost: $500-900
Upper Engine Failure - Piston Ring and Bearing Wear
Occasional · high severity
Typical onset: 140,000-200,000 mi
Symptoms: Excessive oil consumption, 1+ quart per 1,000 miles, Blue smoke from exhaust on acceleration or deceleration, Knocking or tapping noises from engine, especially when cold, Loss of compression, hard starting, poor power
Fix: Both the 3.4L and 3.8L develop piston ring wear and rod bearing issues with deferred oil changes or high mileage. Short block replacement or full rebuild required - pistons, rings, bearings, honing. Machine work plus 16-20 hours labor. Often not economical to repair unless body is pristine.
Estimated cost: $3,500-5,500
Ignition Control Module and Coil Pack Failures
Common · medium severity
Typical onset: 70,000-130,000 mi
Symptoms: Intermittent stalling or no-start, especially when hot, Random misfires on multiple cylinders, Stalls and won't restart until engine cools for 20-30 minutes, Check engine light with misfire or ignition system codes
Fix: The ignition control module (ICM) mounted under the coil packs overheats and fails. Coil packs also crack internally. Start with ICM if symptoms are heat-related (common failure point). 1.5-2.5 hours labor for ICM and coil pack replacement together. Always use ACDelco parts, aftermarket ICMs fail quickly.
Estimated cost: $350-650
Power Steering Pressure Hose and Pump Leaks
Occasional · low severity
Typical onset: 90,000-150,000 mi
Symptoms: Power steering fluid leaking from high-pressure hose or pump, Whining noise from pump, especially at full lock, Stiff or heavy steering intermittently, Visible fluid on ground under front of vehicle
Fix: High-pressure hoses deteriorate where they crimp to fittings, pumps develop seal leaks. Hose replacement 1-1.5 hours, pump 2-3 hours. Replace both if pump is leaking since labor overlaps and hoses are usually degraded anyway.
Estimated cost: $400-750
Front Transmission Mount Failure
Common · low severity
Typical onset: 80,000-140,000 mi
Symptoms: Clunking when shifting from park to drive or reverse, Excessive engine movement visible when accelerating, Vibration through chassis at idle in gear, Harsh shifts, feels like transmission is loose
Fix: The hydraulic front transmission mount collapses internally. Very common wear item on this platform. Replacement requires supporting engine and transmission. 1.5-2 hours labor. Use OEM or high-quality aftermarket, cheap mounts fail within 20k miles.
Estimated cost: $180-320
Fuel Pump and Sender Assembly Failures
Occasional · medium severity
Typical onset: 100,000-160,000 mi
Symptoms: No-start with no fuel pressure (pump failure), Inaccurate or erratic fuel gauge reading (sender failure), Whining or buzzing noise from rear seat area, Stalling or hesitation under load when fuel level is low
Fix: Fuel pumps fail from wear and contamination, senders fail separately. Tank must be dropped or accessed through trunk via cutting access panel (not factory on all models). 3-4 hours labor. Replace entire assembly, not just pump, to avoid comeback for sender issues.
Estimated cost: $450-800
Owner tips
Replace the radiator and add an external transmission cooler at 100k miles BEFORE the internal cooler fails - this single preventive measure can save your transmission
Use only ACDelco ignition parts (ICM, coils, plugs, wires) - aftermarket electrical components fail rapidly on these
Check and change transmission fluid every 30k miles with Dexron VI - the 4T65-E is not maintenance-free despite GM's claims
If buying used, pull the radiator cap and check for any pink/milky residue - walk away if present, transmission is already damaged
Cheap transportation if the radiator and transmission have already been addressed, but a ticking time bomb if original - the trans cooler issue alone makes this a risky used buy without service history proof.

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 engines 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 · 14V400000
2014-07-03
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.
