Most-Reported Infiniti Q50 Problems
These problem areas come up most often in NHTSA owner complaints for the Q50 (all model years combined). Complaint counts reflect reports filed, not the share of vehicles affected, so popular and older models naturally have more.

|---|---|---|---|
| Steering | 133 | 25% | |
| Electrical System | 91 | 17% | |
| Engine | 82 | 16% | |

Steering
133 of the 512 complaints (25%) 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.
Electrical System
91 of the 512 complaints (17%) mention the electrical system. Electrical problems are made worse by desert heat, which ages batteries, cables and connectors. We test the battery, starter and charging system and trace faults to the actual part. See our battery replacement and starter & alternator repair pages.
Engine
82 of the 512 complaints (16%) mention the engine and cooling system. Engine and cooling complaints are best caught early in Phoenix, where heat pushes cooling systems and engine oil to their limits. We diagnose warning lights and check coolant, hoses and oil condition. See our check engine light diagnostics and oil change & maintenance pages.

Most Common Infiniti Q50 Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the Q50. The most-cited is P0720 (output speed sensor circuit), mentioned in 18 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| P0720 | Output speed sensor circuit Failing output speed sensor or wiring; can cause erratic shifting. | 18 |
| P0500 | Vehicle speed sensor Failing speed sensor or wiring; can affect shifting and the speedometer. | 11 |
| C1138 | Manufacturer-specific chassis code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 2 |
| C13E9 | Manufacturer-specific chassis code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 2 |
| B00A0 | Manufacturer-specific body code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 2 |
A code is a clue, not a diagnosis. The same code can have several causes, so we test before replacing parts. See our check engine light diagnostics, and read whether it is safe to drive with the check engine light on.

Keeping a Infiniti Q50 Reliable in Phoenix
Arizona heat is the hardest test a Infiniti will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Q50 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 Q50 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 Infiniti Q50, a pre-purchase inspection shows what the paperwork does not.
