Most-Reported Mercedes-Benz EQE 320+ Problems

Vehicle Speed Control
1 of the 1 complaints (100%) mention vehicle speed control (throttle and cruise control). Speed control complaints involve the throttle, cruise control and related sensors.

Mercedes-Benz EQE 320+ Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the EQE 320+, 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 Mercedes-Benz.
| 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. |

Keeping a Mercedes-Benz EQE 320+ Reliable in Phoenix
Arizona heat is the hardest test a Mercedes-Benz will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a EQE 320+ 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 EQE 320+ 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 Mercedes-Benz EQE 320+, a pre-purchase inspection shows what the paperwork does not.
