Most-Reported Infiniti Q70 Problems
These problem areas come up most often in NHTSA owner complaints for the Q70 (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 | 6 | 30% | |
| Air Bags | 4 | 20% | |
| Engine | 3 | 15% | |

Power Train
6 of the 20 complaints (30%) 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.
Air Bags
4 of the 20 complaints (20%) mention airbags and seat belts. Airbag and restraint issues are often tied to open safety recalls, which are repaired by the manufacturer at no cost to you. Check your VIN on NHTSA's recall lookup first, and we can help with related warning lights and diagnostics. See our auto repair page.
Engine
3 of the 20 complaints (15%) 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 Q70 Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the Q70. The most-cited is P0720 (output speed sensor circuit), mentioned in 2 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. | 2 |
| P0500 | Vehicle speed sensor Failing speed sensor or wiring; can affect shifting and the speedometer. | 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 Q70 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 Q70 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 Q70 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 Q70, a pre-purchase inspection shows what the paperwork does not.
