| Power Train | 560 | 22% | |
| Electrical System | 474 | 18% | |

Engine
641 of the 2,536 complaints (25%) 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.
Power Train
560 of the 2,536 complaints (22%) 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.
Electrical System
474 of the 2,536 complaints (18%) 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.

Most Common Acura MDX Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the MDX. The most-cited is U3000 (manufacturer-specific network code), mentioned in 13 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| U3000 | Manufacturer-specific network code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 13 |
| P0087 | Fuel rail pressure too low Often a weak fuel pump, clogged fuel filter or pressure regulator or injector fault. | 3 |
| P0430 | Catalyst efficiency below threshold (bank 2) Same as P0420 on the second exhaust bank. | 3 |
| P0716 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 3 |
| P0303 | Cylinder 3 misfire Commonly a bad spark plug or ignition coil on that cylinder. | 2 |
| P0301 | Cylinder 1 misfire Commonly a bad spark plug or ignition coil on that cylinder. | 2 |
| P0306 | Cylinder 6 misfire Commonly a bad spark plug or ignition coil on that cylinder. | 2 |
| P2638 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 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 Acura MDX Reliable in Phoenix
Arizona heat is the hardest test a Acura will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a MDX 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 MDX 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 Acura MDX, a pre-purchase inspection shows what the paperwork does not.
