EZ Swap LLC services the Isuzu NQR in Phoenix, AZ, covering model years 2007. If your NQR has a warning light, a strange noise or a safety recall question, our mechanics can diagnose it and give you a clear quote first.
To help NQR owners know what to watch for, we reviewed public records from the National Highway Traffic Safety Administration (NHTSA). For these model years NHTSA has 3 owner complaints on file for the NQR and 2 safety recall campaigns. The most-reported problem areas are fuel system, diesel (1), latches/locks/linkages (1), suspension (1).
Most-Reported Isuzu NQR Problems
These problem areas come up most often in NHTSA owner complaints for the NQR (all model years combined). Complaint counts reflect reports filed, not the share of vehicles affected, so popular and older models naturally have more.
| Problem area (NHTSA component) | Complaints | Share | |
|---|---|---|---|
| Fuel System, Diesel | 1 | 33% | |
| Latches/Locks/Linkages | 1 | 33% | |
| Suspension | 1 | 33% | |
| Steering | 1 | 33% | |
| Engine And Engine Cooling | 1 | 33% |
Fuel System, Diesel
1 of the 3 complaints (33%) mention the fuel system. Fuel system problems can cause stalling, hard starts and poor mileage. We test fuel delivery and related sensors to find the real cause. See our no-start diagnostics and check engine light diagnostics pages.
Latches/Locks/Linkages
1 of the 3 complaints (33%) mention body, doors and latches. Latch and body complaints affect security and safety. We inspect and repair door, hood and trunk hardware. See our auto repair page.
Suspension
1 of the 3 complaints (33%) mention the suspension. Suspension wear shows up as clunks, pulling and uneven tires. We inspect shocks, struts, bushings and joints and align the car after repairs. See our suspension & alignment page.
Isuzu NQR Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the NQR, 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 Isuzu.
| 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 NQR? 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 Isuzu NQR Reliable in Phoenix
Arizona heat is the hardest test a Isuzu will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a NQR 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 NQR 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 Isuzu NQR, a pre-purchase inspection shows what the paperwork does not.
