Most-Reported Maserati Quattroporte GTS Problems
These problem areas come up most often in NHTSA owner complaints for the Quattroporte GTS (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 | |
|---|---|---|---|
| Electrical System | 2 | 100% | |
| Vehicle Speed Control | 1 | 50% |
Electrical System
2 of the 2 complaints (100%) 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.
Vehicle Speed Control
1 of the 2 complaints (50%) 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.
Maserati Quattroporte GTS Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the Quattroporte GTS, 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 Maserati.
| 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. |

Maserati Quattroporte GTS Safety Recalls

- 2015 recall, Electrical System (campaign 15V686000): Maserati North America, Inc. (Maserati) is recalling certain model year 2014 Quattroporte GTS V8 vehicles manufactured October 1, 2013, to December 31, 2013.
- 2013 recall, Electrical System (campaign 13V589000): Maserati North America, Inc. (Maserati) is recalling certain model year 2014 Quattroporte GTS V8 vehicles. The affected vehicles have an improper Y-connection crimp in the alternator-starter motor wiring harness.
Keeping a Maserati Quattroporte GTS Reliable in Phoenix
Arizona heat is the hardest test a Maserati will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Quattroporte GTS 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 Quattroporte GTS 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 Maserati Quattroporte GTS, a pre-purchase inspection shows what the paperwork does not.
