Oil Pump Failures in Twin-Turbo V6 Models

The Achilles heel across 2014–2017 Quattroportes equipped with the twin-turbo 3.0L V6 lies with the oil pump. These critical components can abruptly fail and trigger rapid loss of oil pressure that can permanently damage the engine in short order.

Warning signs pointing to oil pump failure include:

• Illuminated oil pressure warning light
  
• Unusual engine noises such as knocking or ticking
  
• Abrupt loss of oil pressure

If you notice these symptoms in your late-model V6 Quattroporte, have your sedan transported to our Fremont shop immediately to prevent catastrophic engine damage. Our technicians will diagnose the issue and replace the oil pump using only factory-approved Maserati components to restore full lubrication protection.

What about other engine configurations? Do they experience similar oil pump issues over time?

Adaptive Headlight Defects in Recent Models

The adaptive headlight system introduced for 2013–2020 Quattroportes brought advanced technology to this sedan’s lighting capabilities. Using input from steering angle and other sensors, specialized motors automatically pivot the headlights to match driving conditions and improve night visibility.

However, the motors and control module regulating this complex system can fail over time, leading to issues like:

• Limited or disabled headlight beam adjustment
  
• Illuminated warning lights on the dashboard
  
• Reduced visibility when driving at night

If you experience these symptoms in your Quattroporte, faulty adaptive headlight components may be to blame. Our technicians will diagnose the exact failure and take corrective action ranging from control module replacement to wiring harness repair. Only genuine Maserati components are used to restore your adaptive headlights’ functionality.

Air Suspension Leaks

The Skyhook adaptive air suspension fitted to many 2013–2020 Quattroportes provides a smooth, comfortable ride by way of air springs with automatically adjustable pressures. But over years of service, those air lines and springs can develop leaks and undermine suspension performance.

Watch for these warning signs of leaking air suspension components:

• Vehicle leaning dramatically to one side
  
• Illuminated warning lights on the dashboard
  
• Harsh ride quality and handling issues

Don’t hesitate to have your Quattroporte inspected if you notice uneven stance or ride height combined with the above symptoms. Our technicians will test the entire system to identify leak points, then repair or replace faulty air suspension hardware. This restores the factory ride height, handling precision, and comfort you expect from Maserati.

Transmission Control Module Troubles

The 8-speed automatic transmission paired with most Quattroporte engines plays an integral role in delivering refined, responsive acceleration. At the heart of this transmission lies the transmission control module (TCM)—an onboard computer regulating gear selection, shift points, and performance.

Faulty TCM programming or electrical issues in the 2014–2017 models can trigger various symptoms, including:

• Harsh, erratic gear shifts
  
• Warning lights illuminating on the dashboard
  
• Limp mode activation

If you experience unusual transmission behavior in this era of Quattroportes, there may be an underlying TCM problem. Our technicians will hook up diagnostic computers to read fault codes and determine if software bugs or failed components are at fault. From there, we can update firmware or replace the TCM to restore smooth, reliable shifting.

Fuel Pump Breakdowns

The fuel pump in your Quattroporte operates silently for years as it moves gasoline from the tank to the injection system. But this crucial component is vulnerable to eventual electric or mechanical failure—especially once your sedan crosses 100k miles or more.

Be on the lookout for symptoms of fuel pump breakdown, including:

• Check engine warning and related trouble codes
  
• Hard starting or stalling
  
• Poor acceleration

Should you notice rough running paired with these warning signs, don’t delay having your Quattroporte’s fuel system inspected. Our techs will diagnose the pump failure and replace it with a new Maserati unit, restoring smooth power delivery. This preventative repair also reduces the risk of being left stranded by a bad fuel pump down the road.

Timing Chain Tensioner Defects

The powerful twin-turbo 3.0L V6 and 3.8L V8 engines powering 2013–2020 Quattroportes utilize timing chains to coordinate valve and ignition timing. Dedicated tensioners keep these chains taut to prevent premature wear and synchronization issues.

Unfortunately, many Quattroporte engines see the tensioners fail ahead of schedule—typically before 60k miles. Listen for these symptoms pointing to tensioner-related problems:

• Knocking or rattling noises from the engine
  
• Chain slack enabling valve timing issues

If you detect abnormal engine noises, don’t ignore the warning signs. Have the technicians at Fremont Foreign Auto inspect the timing components right way. We’ll diagnose tensioner wear and replace the defective parts with Genuine Maserati hardware for long-lasting performance. This prevents further timing chain damage down the road.

Electrical Gremlins

From touchscreens to power seats and automatic climate control, the modern Quattroporte relies on countless electrical components talking to each other. But failures can happen thanks to faulty control units, fluky software, or wiring problems.

Watch for these symptoms of deeper-rooted electrical issues:

• Warning lights illuminating on the dashboard
  
• Non-responsive infotainment or climate control interfaces
  
• Power seat, door lock, or window problems

Our electrical diagnostic tools and many years of experience mean we can tackle any of the ghosts in the machine haunting your Quattroporte’s electrical architecture. We’ll chase down wiring faults, update control module programming, or replace damaged components until every system functions properly again.

We hope this overview better informs Quattroporte owners about why problems happen and what to watch for across these exceptional sedans. But most importantly, we want to emphasize that the team at Fremont Foreign Auto has the Maserati-specific expertise to accurately diagnose issues with your Quattroporte—and the equipment and genuine components needed to complete repairs correctly the first time.
