The Maserati Quattroporte (Italian pronunciation: ) is a four-door luxury sports sedan produced by Italian automobile manufacturer Maserati. The name translated from Italian means "four doors". The car is in its sixth generation, with the first generation introduced in 1963.

Quattroporte I (AM107, 1963–1969)

The original Maserati Quattroporte (Tipo AM107) was built between 1963 and 1969. It was a large saloon powered by V8 engines—both firsts for a series production Maserati automobile.

History

The task of styling the Quattroporte was given to Turinese coachbuilder Pietro Frua, who drew inspiration from a special 5000 GT (chassis number 103.060) which he had designed in 1962 for Prince Karim Aga Khan. While the design was by Frua, body construction was carried out by Vignale.

Common 2018 Maserati Quattroporte problems

The Maserati Quattroporte 2018 has been reported to have several common issues by owners:

Transmission-Related Issues:
Complaints include rough shifting, delayed engagement, and even complete transmission failure. These problems can be caused by defective solenoids, faulty valve bodies, or inadequate fluid levels. Seeking professional assistance is crucial to prevent further damage and avoid being stranded.

Suspension Challenges:
Some owners have reported suspension noise, excessive vibration, and a rough ride quality. Prematurely worn-out bushings, damaged shocks or struts, and misaligned suspension components are common culprits. Regular maintenance and timely replacement of worn parts can help restore the Quattroporte's driving experience.

Engine-Related Problems:
Issues like rough idling, engine misfires, and reduced power output have been noted. These symptoms may arise from faulty fuel injectors, ignition coil failures, or air intake leaks. Regular servicing and tune-ups are recommended to identify and rectify these engine performance issues.

These problems highlight the importance of regular maintenance and prompt attention to any issues that arise to ensure a pleasant ownership experience with the Maserati Quattroporte 2018.

What is the most common problem with Maserati?

From brake issues to clutch and transmission problems, faulty electrical systems, and poor build quality, Maserati vehicles have a reputation for being unreliable. It is essential to factor in the potential costs of repairs and maintenance when making your decision.

Is a Maserati Quattroporte expensive to maintain?

These cars are expensive to maintain, particularly when repairs are necessary. Annual maintenance for most owners typically runs between $2,000 and $3,000 per year for fluid changes, tires, etc., but I think you'll find that's based on fairly limited drivng (est. 4,000 to 7,000/yr.).

How dependable are Maserati's?

Is Maserati reliable? The brand isn't known for being overly reliable, suffering several issues, with the most common faults being electrical or affecting the axle and suspension. Unfortunately, while Maserati is becoming increasingly popular among buyers, its reliability has not improved.

Is Maserati Quattroporte comfortable?

Ride comfort is decent enough on the whole. The Quattroporte is certainly more comfortable than the smaller Ghibli, which is just too stiff, but it won't keep you isolated from battle-scarred British tarmac anything like as well as a Mercedes S-Class.

VEHICLE SPEED CONTROL PROBLEM

Date Of Incident: 2019-11-14
Crash: 1
VIN: ZAM56YRS5J1
Components: VEHICLE SPEED CONTROL
Summary: I WAS DRIVING THIS VEHICLE IN "SPORT" MODE. I ACCELERATED FROM A STOPPED POSITION, RATHER AGGRESSIVELY TO GET UP TO SPEED (ABOUT 30-35 MPH). WHEN I TOOK MY FOOT OFF THE GAS PEDAL, THE CAR CONTINUED TO ACCELERATE UNCOMMANDED. I PRESSED THE BRAKE AS HARD AS I COULD, BUT THE ENGINE REMAINED AT FULL POWER ATTEMPTING TO ACCELERATE FORWARD. I WAS NEARLY ABLE TO GET THE VEHICLE TO A COMPLETE STOP, BUT THE ENGINE OVERPOWERED ME WITH BOTH FEET STANDING ON BRAKE PEDAL. IT SHUDDERED FORWARD ABOUT 25 FEET, MOVING AT LESS THAN 5MPH, ALMOST LIKE THE ANTILOCK BRAKES WERE CAPTURING AND RELEASING, UNTIL I STRUCK A VEHICLE STOPPED AT A RED LIGHT IN FRONT OF ME. THE DISPLAY READ "SERVICE ENGINE THROTTLE CONTROL." ONCE I STRUCK THE OTHER VEHICLE, MY VEHICLE FINALLY CAME TO A COMPLETE STOP. I PUT THE CAR IN PARK, AND THE ENGINE FINALLY STOPPED REVVING. THE FLOOR MATS WERE IN THEIR PROPER PLACE, SO THEY WERE NOT A CONTRIBUTING FACTOR. THIS WAS ACTUALLY THE SECOND TIME THAT THE CAR HAD ACCELERATED ON ITS OWN, BOTH OCCURRING IN CONJUNCTION WITH AGGRESSIVE APPLICATION OF THE GAS PEDAL. THE FIRST TIME I WAS ABLE TO OVERCOME IT FAIRLY QUICKLY, AND THOUGHT IT WAS JUST AN ANOMALY. IT MAY BE IMPORTANT TO NOTE THAT THE MANUFACTURER APPROVED AND COMPLETELY REPLACED THE ENGINE CONTROL MODULE (WHICH I WAS INFORMED BY THE DEALERSHIP WAS A RARE EVENT) ONLY 2 MONTHS PRIOR TO THIS INCIDENT, DUE TO A VIRTUAL ELECTRONIC MELTDOWN WITH THE ENGINE CONTROL. BOTH UNCOMMANDED ACCELERATION EVENTS OCCURRED AFTER THIS REPLACEMENT. AFTER THE "INVESTIGATION" BY THE MANUFACTURER, THEY CLAIM THERE WAS NO PROBLEM AND ACCEPTED NO RESPONSIBILITY FOR THE INCIDENT, NOR DID THEY TAKE ANY CORRECTIVE ACTIONS TO ENSURE OUR FUTURE SAFETY. THE VEHICLE CURRENTLY HAS ABOUT 4500 MILES. I'VE HAD IT FOR JUST UNDER 1 YEAR, AND IT HAS BEEN OUT OF SERVICE NEARLY 2 FULL MOUTHS WITH THREE ELECTRONIC/ELECTRICAL PROBLEMS.

Although the Ferrari car boasts a powerful engine and a luxurious leather and carbon fiber interior, it unfortunately has some flaws that you should be aware of. One of the most inconvenient features is the Auto Stop/Start function, which can be difficult to turn off. Additionally, the Air recirculate button does not stay engaged, which can lead to warm exhaust. The cup holders are also quite shallow and small, making it difficult to store larger items like an iPhone. Despite these issues, the car is still quite fast and powerful. However, it may not be the best choice for those who prefer a more controlled driving experience. Ultimately, it is up to the individual to decide if this car is the right fit for them. Thank you for considering this information before making your decision.

Incredible sound and design in this Ferrari powered monster

Great daily driver. It's easy on the eyes.

I highly recommend
Tristin Runolfsdottir 2024-07-20

A pleasure to drive! At 43,000 miles, this car has proven to be reliable and comfortable. The large trunk and comfortable seats make it easy to live with. While maintenance costs can be expensive, even at a qualified independent shop, it's worth it for the fantastic sound of the engine!
Rollin Maggio 2024-07-16

I'm still really enjoying the car. I've had to replace the brake shoes and headlights at this point. The only downside is that the new brake shoes tend to squeal when stopping slowly. Nonetheless, I still love the car.
