Volvo XC40 T4 Reliability - Problems & Costs

Common Problems

Sensus infotainment system failure

€0 - 2,0001 of 6

Touchscreen freezes, goes black, or reboots spontaneously, affecting navigation and reversing camera · more· less

The Volvo Sensus infotainment system in the XC40 is one of the most frequently reported issues across all variants. The 9-inch touchscreen can freeze, go completely black, or spontaneously reboot while driving. During failures, the reversing camera, navigation, climate controls (which are screen-only), and audio all become unavailable. A class action lawsuit has been filed over these infotainment defects. Most incidents can be temporarily resolved by a forced reboot (holding the home button for 10 seconds) or locking the car for 30 minutes. Persistent issues typically require replacement of the IHU (Infotainment Head Unit) at around 1,500-2,000 euros at a Volvo dealer. Software updates from Volvo have improved stability on later production cars. Verify the car has the latest software version installed and test all functions thoroughly during inspection.

Front strut mount bearing wear

€300 - 8002 of 6

Top mount bearings wear prematurely, causing clunking or creaking when turning at low speeds · more· less

The front strut mount bearings on the XC40 are a known weak point across all variants, including the T4. Owners report clunking, creaking, or popping noises from the front suspension when turning at low speeds, particularly noticeable in parking manoeuvres. The issue has been reported as early as 20,000-30,000 km, though it more commonly appears between 50,000-80,000 km. Volvo has released updated replacement bearings. Replacement typically costs 300-400 euros at an independent shop (both sides, parts and labour plus alignment) or up to 800 euros at a Volvo dealer. Both sides should be replaced simultaneously. The problem can recur even after repair, though the updated parts are more durable.

12V battery drain

€150 - 3503 of 6

Battery drains within 7-14 days when parked due to electronic modules failing to enter sleep mode · more· less

The XC40 has a documented parasitic drain issue where various electronic modules fail to enter sleep mode properly after the car is locked. The car can fully drain its 12V battery within 7-14 days of not being driven, particularly in cold weather. Volvo has released multiple software updates to improve sleep mode behaviour, but the issue persists on some cars. The drain is typically 50-100 mA when it should be under 30 mA. A quality trickle charger (such as a CTEK MXS 5.0) is strongly recommended for any XC40 that is not driven daily. Battery replacement costs 150-350 euros depending on specification. Check the battery age and test resting voltage before purchase.

Power tailgate strut failure

€200 - 8004 of 6

Electric tailgate struts leak or fail, preventing proper opening or closing · more· less

The powered tailgate struts on the XC40 can develop internal corrosion due to water ingress, causing them to stick, fail to hold the tailgate open, or prevent full closure. Early models (2018-2020) are more susceptible due to the original strut mounting position. Later production revised the design. Aftermarket replacement struts cost approximately 200-250 euros for the pair, but Volvo dealers typically quote 600-800 euros including labour because both sides must be replaced simultaneously with the current parts. Test the tailgate multiple times from the button, key fob, and interior switch during inspection.

Balance shaft module noise

€800 - 1,5005 of 6

Whining noise from engine between 1,000-2,500 rpm caused by worn balance shaft bearings · more· less

The VEA 2.0-litre engine uses a balance shaft module bolted to the bottom of the block containing two counter-rotating shafts. In rare cases, the bearings in this module wear, producing a distinctive whining noise that rises and falls with engine speed, most noticeable at 1,000-2,500 rpm. Volvo has acknowledged the issue and released an updated module with improved bearings. Replacement costs approximately 800-1,000 euros at an independent specialist (parts plus 3 hours labour) or 1,200-1,500 euros at a Volvo dealer. This is a rare fault affecting a small minority of VEA engines. Listen carefully for any unusual whining during the test drive at low revs.

Sunroof drain blockage causing water ingress

€100 - 1,5006 of 6

Clogged drain tubes allow water to enter the cabin, potentially damaging electronics · more· less

XC40s equipped with a sunroof are susceptible to drain tube blockages. The four drain tubes (two front, two rear) can become clogged with leaves and debris, causing water to back up and leak into the cabin via the A-pillars or rear quarter panels. Minor blockages cause damp carpets and musty smells. Severe cases can result in standing water under the carpets, leading to mould and electrical damage to modules located under the seats. Cleaning the drains is straightforward preventive maintenance (100-150 euros if done at a workshop). However, if water has already caused electrical damage, repairs can escalate to 1,000-1,500 euros. Inspect for damp carpets, water stains on headliner edges, and musty odours during inspection.

Reliable engine, but electronics and suspension need attention

The VEA 2.0-litre four-cylinder in the T4 is a proven unit shared across the entire Volvo range, and engine failures are rare. The main concerns centre on the Sensus infotainment system, which is problematic across all XC40 variants, and the front strut mount bearings which wear prematurely. Battery drain is a nuisance rather than an expensive problem, and tailgate struts are a manageable wear item. The T4 avoids the serious crankshaft defect found on the three-cylinder T3 manual models. Overall, the XC40 T4 is a reasonable used buy if you verify the infotainment is functioning and the suspension has been addressed.

Pre-Purchase Inspection Checklist

General checks

Service history
Complete Volvo dealer or authorized specialist records. Verify oil changes at maximum 12-month or 30,000 km intervals.
Tire condition
Check tread depth, age (date codes), and uneven wear. XC40 T4 typically runs 18" or 19" tires (235/55R18 or 235/50R19).
Cold start
Start the engine completely cold and listen for unusual sounds in the first 30 seconds. A brief turbo whistle is normal; sustained whining is not.
Test drive
Drive for at least 20 minutes including city and motorway. Check gearbox shifts, braking, and all electronic functions.

Specific for this vehicle

Test all Sensus infotainment functions
Navigate through every menu, test navigation, reversing camera, Apple CarPlay/Android Auto, and audio. Wait 5 minutes with the car running to check for freezing or rebooting. Verify the latest software version is installed.
Turn the steering wheel lock-to-lock at low speed
Listen for clunking, creaking, or popping from the front suspension. This is the primary symptom of worn strut mount bearings. Test in both directions.
Check 12V battery voltage and age
Use a multimeter to verify the battery reads above 12.4V with the engine off. Check the battery date code. Ask how often the car is driven and whether it has been left standing for extended periods.

+ 3 more checksShow less

Test the power tailgate multiple times
Open and close the electric tailgate at least 3 times using the button, key fob, and interior switch. Listen for straining noises and check it latches fully each time.
Inspect for water ingress (if sunroof equipped)
Check for damp carpets in footwells, water stains near the headliner edges, and musty odours. Lift floor mats and press the carpet to feel for moisture underneath.
Listen for balance shaft whine at low revs
During the test drive, reduce speed to 30-50 km/h in a high gear so the engine runs at 1,000-2,500 rpm. Listen for any unusual whining noise that rises and falls with engine speed.

Recalls and Technical Service Bulletins

AEB software - automatic emergency braking may not detect obstacles (2019-2020 models, recall R29998) Verify completed

Starter motor failure - may fail to engage or cause noise on start (2018-2019 models, recall R10143) Verify completed
