Most-Reported Volvo EX40 Problems
These problem areas come up most often in NHTSA owner complaints for the EX40 (all model years combined). Complaint counts reflect reports filed, not the share of vehicles affected, so popular and older models naturally have more.

| Power Train | 2 | 66% | |
| Steering | 1 | 33% | |

Service Brakes
2 of the 3 complaints (66%) mention brakes. Brake complaints turn up on nearly every vehicle, and Phoenix stop-and-go traffic wears brake parts quickly. We measure pads and rotors, check calipers and fluid, and replace only what is worn. See our brake repair page.
Power Train
2 of the 3 complaints (66%) mention the powertrain. Powertrain complaints can range from rough shifting to loss of drive. We road test, scan for stored codes and inspect fluids before recommending any repair. See our auto repair page.
Steering
1 of the 3 complaints (33%) mention steering. Steering complaints deserve prompt attention. We inspect steering components and alignment so the car tracks straight and responds predictably. See our suspension & alignment page.

Volvo EX40 Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the EX40, so we do not have a model-specific ranking to show. These are the check engine codes we see most often on vehicles in Phoenix heat, and any of them can show up on a Volvo.
| Code | What it means |
|---|---|
| P0420 | Catalyst efficiency below threshold (bank 1) Often a worn catalytic converter, but failing oxygen sensors or exhaust leaks can set it too. Can cause an emissions test failure. |
| P0300 | Random or multiple cylinder misfire Worn spark plugs, failing ignition coils, fuel or vacuum problems. Do not ignore a flashing check engine light. |
| P0171 | System too lean (bank 1) Often a vacuum leak, dirty MAF sensor, weak fuel delivery or a failing oxygen sensor. |
| P0455 | EVAP system large leak Missing or loose gas cap, or a disconnected or cracked vapor hose. |
| P0128 | Coolant temperature below thermostat regulating temperature Usually a thermostat stuck open. Fix it to restore efficiency and cabin heat. |
| P0442 | EVAP system small leak Loose or worn gas cap, cracked hose or purge or vent valve. |
| P0301 | Cylinder 1 misfire Commonly a bad spark plug or ignition coil on that cylinder. |
| P0401 | EGR flow insufficient Clogged EGR passages or a stuck EGR valve. |
Got a check engine light on your EX40? A code is a clue, not a diagnosis, so we scan it and test the system before replacing anything. See our check engine light diagnostics.

Keeping a Volvo EX40 Reliable in Phoenix
Arizona heat is the hardest test a Volvo will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a EX40 that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for EX40 owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used Volvo EX40, a pre-purchase inspection shows what the paperwork does not.
