The 2019 Volvo S90 is built on Volvo's SPA platform with their Drive-E 2.0L four-cylinder engines (T5 turbo, T6 turbo+supercharger, T8 plug-in hybrid). While sophisticated and comfortable, these engines have a catastrophic piston/connecting rod failure issue that can grenade the motor, plus transmission and electrical gremlins that plague the platform.
Catastrophic Engine Failure - Piston/Connecting Rod Damage
Occasional · high severity
Typical onset: 30,000-80,000 mi
Symptoms: sudden loss of power and severe knocking, metal shavings in oil, check engine light with misfire codes, complete engine seizure in worst cases
Fix: This is the big one. The 2.0L Drive-E engines can suffer catastrophic piston skirt failure or connecting rod bearing failure, sending metal through the entire engine. Requires complete engine rebuild (pistons, rings, bearings, crankshaft machining) or short block replacement. 25-35 hours labor for full rebuild, 18-22 hours for short block swap if available.
Estimated cost: $8,000-15,000
Transmission Oil Cooler Leaks
Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: transmission fluid puddles under vehicle, transmission overheating warnings, burnt transmission fluid smell, harsh shifting when hot
Fix: The Aisin 8-speed transmission oil cooler develops leaks at the line connections and cooler core. Requires cooler replacement and often new lines. Fluid contamination can damage the transmission if not caught early. 3-5 hours labor.
Estimated cost: $800-1,400
Transmission Mount Failure
Common · low severity
Typical onset: 40,000-70,000 mi
Symptoms: clunking when shifting from Park to Drive/Reverse, vibration at idle in gear, excessive engine movement visible from engine bay, rough shifts at low speed
Fix: The hydraulic transmission mount collapses or leaks fluid, allowing excessive drivetrain movement. Common on all SPA platform cars. Replacement is straightforward but requires supporting the drivetrain. 2-3 hours labor.
Estimated cost: $400-700
Automatic Emergency Braking False Activations
Occasional · high severity
Symptoms: sudden unexpected braking with no obstacle present, City Safety warning messages, radar sensor errors in rain/snow, system activating on shadows or overpasses
Fix: Covered by NHTSA recall, but software updates don't always resolve it. Radar sensors in the grille get dirty or misaligned. May require sensor cleaning, recalibration, or replacement if damaged. Software flash takes 1 hour, sensor replacement adds 2-3 hours.
Estimated cost: $150-1,200
Infotainment System Freezing and Sensus Issues
Common · low severity
Symptoms: touchscreen becomes unresponsive, backup camera black screen or frozen image, climate controls not responding, system rebooting randomly while driving
Fix: The Sensus infotainment system suffers from software glitches and occasional hardware failures. Often resolved with software updates (covered by recall for some VINs), but screen replacement needed in persistent cases. Software update 1 hour, screen replacement 3-4 hours.
Estimated cost: $0-2,500
Fuel Filter Clogging (High-Pressure)
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: rough idle and hesitation, loss of power under acceleration, long cranking before starting, fuel pressure fault codes
Fix: The high-pressure fuel filter in the tank assembly can clog prematurely, especially with lower-quality fuel. Not a regular maintenance item in Volvo's schedule but should be. Requires dropping the fuel tank. 4-5 hours labor.
Estimated cost: $600-1,000
Turbocharger Wastegate Rattle
Occasional · low severity
Typical onset: 50,000-90,000 mi
Symptoms: rattling noise on cold start that disappears when warm, sound comes from engine bay, passenger side, no performance loss initially, eventual boost pressure issues if ignored
Fix: The turbo wastegate actuator arm develops play, causing a distinctive rattle. Common across Drive-E engines. Turbo replacement or rebuild required; these are integrated units. 8-10 hours labor for turbo replacement on T6 (turbo+supercharger is worse).
Estimated cost: $2,000-3,500
Owner tips
Use full synthetic 0W-20 oil and change every 5,000 miles despite Volvo's 10k interval — the piston failure issue may be partially oil-related
Check transmission fluid level and condition regularly; these transmissions are sensitive to low or burnt fluid
Keep radar sensors clean and have them recalibrated after any front-end work to prevent false AEB activations
Budget for a potential engine replacement if buying used — some buyers negotiate $3-5k off asking price as insurance against the piston failure risk
Beautiful cars with excellent safety and comfort, but the engine grenade risk makes these a gamble unless you find one with a documented engine replacement under warranty or can negotiate the price to cover that risk.
