Most-Reported Isuzu I 350 Problems
These problem areas come up most often in NHTSA owner complaints for the I 350 (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 | |
|---|---|---|---|
| Exterior Lighting | 2 | 50% | |
| Service Brakes, Hydraulic | 1 | 25% | |
| Vehicle Speed Control | 1 | 25% | |
| Equipment | 1 | 25% | |
| Tires | 1 | 25% |
Exterior Lighting
2 of the 4 complaints (50%) mention lighting and visibility. Lights, wipers and visibility items are quick to fix and are on every rideshare inspection checklist. We check them as part of our inspection prep. See our rideshare inspection prep page.
Service Brakes, Hydraulic
1 of the 4 complaints (25%) 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.
Vehicle Speed Control
1 of the 4 complaints (25%) mention vehicle speed control (throttle and cruise control). Speed control complaints involve the throttle, cruise control and related sensors. We scan for stored codes and test the throttle system and sensors to find the actual cause instead of guessing. See our check engine light diagnostics and auto repair pages.
Isuzu I 350 Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the I 350, 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 I 350? 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 I 350 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 I 350 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 I 350 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 I 350, a pre-purchase inspection shows what the paperwork does not.
