The 2011 Volvo S40 shares the Ford-era P1 platform and is generally reliable, but the turbocharged 2.5L T5 variant suffers from catastrophic internal engine failures due to oil system deficiencies, while all models face transmission cooling and mount issues that can lead to expensive repairs if ignored.
Symptoms: Knocking or rattling from engine at idle or under load, Metal shavings in oil during changes, Sudden loss of oil pressure, Check engine light with misfire codes, Catastrophic engine seizure
Fix: The 2.5T suffers from oil starvation to rod bearings and pistons, often requiring complete engine rebuild or short block replacement. Expect 18-25 labor hours for short block swap, more for full rebuild. This is THE issue that kills these cars—often happens suddenly after extended oil change intervals or aggressive driving.
Estimated cost: $5,500-9,000
Transmission Oil Cooler Failure
Common · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Pink or milky transmission fluid, Transmission slipping or delayed engagement, Coolant in transmission pan, Overheating transmission, Rough shifting after warmup
Fix: The internal oil cooler inside the radiator fails, allowing coolant to mix with ATF—which destroys the transmission if not caught early. Requires radiator replacement, complete transmission fluid flush (multiple times), and often transmission rebuild if contamination went unnoticed. 6-8 hours labor for cooler/flush, add 12-16 hours if transmission needs rebuild.
Symptoms: Loud clunk when shifting into drive or reverse, Excessive engine movement visible from engine bay, Vibration through cabin at idle, Harsh shift feel, Driveline shudder during acceleration
Fix: The hydraulic transmission mount collapses, allowing excessive powertrain movement. Common on all P1 Volvos. Replacement is straightforward but requires supporting the engine/trans. 2-3 hours labor. Replace with OEM or quality aftermarket—cheap mounts fail quickly.
Estimated cost: $350-600
PCV System Clogging and Oil Leaks
Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Oil leaking from valve cover gasket, Excessive oil consumption, Rough idle with oil smell, Whistling noise from engine bay, Oil residue around intake and turbo lines
Fix: The PCV breather system clogs with sludge, creating crankcase pressure that blows out gaskets. Requires PCV valve, breather box cleaning or replacement, and often valve cover gasket. If caught early, 3-4 hours labor. Ignoring it accelerates turbo seal failure and the rod bearing issues above.
Estimated cost: $500-900
Fuel Filter Clogging (Non-Turbo Models)
Occasional · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: Hard starting when engine is hot, Hesitation or stumbling under acceleration, Stalling at idle after driving, Fuel pump whining louder than normal, Intermittent no-start conditions
Fix: The in-tank fuel filter screen clogs, starving the engine. Requires fuel pump module removal. Often misdiagnosed as pump failure. 2-3 hours labor. Volvo doesn't list it as maintenance, but it should be inspected if symptoms appear.
Estimated cost: $400-650
Front Lower Control Arm Bushings
Common · low severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunking over bumps, Wandering or imprecise steering, Inner tire wear, Vibration through steering wheel, Car feels loose or floaty in corners
Fix: The front lower control arm bushings deteriorate, affecting handling and tire wear. Common on P1 cars in rust belt or with spirited driving. Replace control arms as assemblies—bushings alone are difficult to press. 2.5-3.5 hours labor for both sides.
Estimated cost: $600-1,000
Owner tips
If buying a T5 turbo model, demand oil analysis history and compression test—most engine failures stem from poor maintenance or already-damaged internals
Check transmission fluid color religiously every 15k miles; pink or milky means immediate cooler replacement before transmission is ruined
Replace PCV system components every 60k miles preventively—cheap insurance against gasket and turbo failures
Use quality synthetic oil (0W-30 or 5W-30) and change every 5,000 miles max on turbo engines, regardless of OEM interval
Avoid turbocharged T5 models unless you have comprehensive service records and budget for engine work; naturally-aspirated 2.4L versions are safer bets but still need diligent transmission cooler monitoring.

VOLVO IS RECALLING CERTAIN MODEL YEAR 2011 S40 PASSENGER VEHICLES. A CRACK ON THE TOP SIDE OF THE PASSENGER SIDE SUPPORT MEMBER IN THE ENGINE COMPARTMENT MAY HAVE DEVELOPED DURING THE FORMING PROCESS IN COMPONENT PRODUCTION.
Consequence: THE CRACK COULD HAVE AN EFFECT ON THE FRONT STRUCTURE AND MAY REDUCE THE CRASH PERFORMANCE OF THE VEHICLE.
Remedy: DEALERS WILL INSPECT FOR CRACKS ON THE TOP SIDE OF THE PASSENGER SIDE SUPPORT MEMBER IN THE ENGINE COMPARTMENT. IF NO CRACK IS FOUND, NO FURTHER ACTION IS NEEDED. IF THE INSPECTION REVEALS THAT A VEHICLE HAS A CRACK IN THE SIDE SUPPORT MEMBER, THE VEHICLE WILL IMMEDIATELY BE TAKEN OUT OF SERVICE. A NEW REPLACEMENT VEHICLE OF EQUAL SPECIFICATION WILL BE PROVIDED BY VOLVO. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE APRIL 15, 2011.
