The most-reported problem areas are suspension (24), electrical system (15), service brakes (11).
Most-Reported Hyundai Equus Problems
These problem areas come up most often in NHTSA owner complaints for the Equus (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 | |
|---|---|---|---|
| Suspension | 24 | 24% | |
| Electrical System | 15 | 15% | |
| Service Brakes | 11 | 11% | |
| Engine | 9 | 9% | |
| Exterior Lighting | 9 | 9% | |
| Seats | 9 | 9% | |
| Power Train | 8 | 8% | |
| Steering | 7 | 7% |
Suspension
24 of the 97 complaints (24%) 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.
Electrical System
15 of the 97 complaints (15%) 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.
Service Brakes
11 of the 97 complaints (11%) 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.

Hyundai Equus Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the Equus, 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 Hyundai.
| 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 Equus? 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 Hyundai Equus Reliable in Phoenix
Arizona heat is the hardest test a Hyundai will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Equus 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 Equus 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 Hyundai Equus, a pre-purchase inspection shows what the paperwork does not.
