2004 Infiniti M45 problems
The Infiniti M is a line of mid-size luxury (executive) cars from the Infiniti luxury division of Nissan. From 2013 (model year 2014) on it has been marketed as the Infiniti Q70, reflecting the company's new naming scheme.
The first iteration was the M30 Coupé/Convertible, which were rebadged JDM Nissan Leopard. After a long hiatus, the M nameplate was used for Infiniti's mid-luxury sedans (executive cars). First was the short-lived M45 sedan, a rebadged version of the Japanese-spec Nissan Gloria. The next generations, the M35/45 and M37/56/35h/30d, became the flagship of the Infiniti brand and are based on the JDM Nissan Fuga.
First generation (1989–1992)
The Infiniti M30 was a 2-door coupé based on the Japanese market Nissan Leopard (chassis code F31). It was launched in 1989 for the 1990 model year as a luxury coupe alternative to the Infiniti Q45, and was intended to be an alternative to the Lexus SC and Acura Legend coupe for the North American market.
Unlike its competitors that were designed with the American market in mind and were launched as brand-new models, the M30 was based on a somewhat dated platform that was originally designed for the Japanese market; when the Leopard was imported to the United States, few changes were made to the exterior but the interior was revised to better suit American tastes; a leather interior was standard in the M30, and several features in the Leopard such as a center-mounted television screen and a digital instrument cluster weren't available in the M30 as those features were perceived as gimmicks in western car markets.
The M30's angular design aesthetics and on-road performance were viewed as outdated, especially considering a redesigned Acura Legend coupe was launched in 1991. The interior came in for criticism for its outdated ergonomics and lack of room. While the Japanese-market Leopard had received a new dashboard along with the 1988 facelift, economics precluded making a left-hand-drive version of the new dashboard and the M30 was instead fitted with the LHD version of the R31 Skyline's rectilinear dashboard, first presented in 1985.
The M30 made up for these deficiencies in its somewhat lower price; whereas the 1990 Acura Legend coupe started at $27,325 before options and the 1990 BMW 325i started at $24,650 before options, the M30 started at $23,500, and had no factory options, per Infiniti's pricing structure used at the time. Dealerships offered an in-car cellular telephone and in-dash CD player as optional accessories, amongst other items.

Common 2004 Infiniti M45 problems
The Infiniti M45, produced in the early 2000s, has been reported to have several common problems by its owners. Here are some of the issues that have been identified:
- Transmission Problems: Some owners have reported that the transmission in their Infiniti M45 is slow to respond when shifting gears, particularly in traffic. This can be frustrating for drivers and can lead to a less enjoyable driving experience. It's worth noting that this issue is not unique to the Infiniti M45 and is a common problem with many cars of this vintage.
- Suspension Struts: The suspension struts in the Infiniti M45 have been reported to fail over time, particularly in high-mileage vehicles.
- Crankshaft Positioning Sensor Failure: The crankshaft positioning sensor is a critical component of the engine management system, and when it fails, it can cause drivability issues.
- Spark Plugs: The spark plugs in the Infiniti M45 have been reported to fail prematurely, particularly in high-mileage vehicles. This can lead to a loss of power and fuel efficiency, as well as increased emissions. It's recommended that the spark plugs be replaced every 50,000 miles or so, depending on the driving conditions and the age of the vehicle.
- Trunk Struts: The trunk struts in the Infiniti M45 have been reported to fail regularly, particularly in high-mileage vehicles.
In conclusion, the Infiniti M45 has been reported to have several common problems, particularly in high-mileage vehicles.

ENGINE PROBLEM
- Date Of Incident: 2013-06-03
- VIN: JNKAY41E04M
- Components: ENGINE
- Summary: THE FIRST INCIDENT HAPPENED ON JUNE 3RD DRIVING TO WORK AND THE CAR JUST GAVE OUT. IT STALLED, LIGHTS CAME ON THE DASHBOARD AND CAR DIED. I WAS ABLE TO DRIFT TO A SIDE STREET IN WHICH I TRIED TO START THE CAR AGAIN; HOWEVER, THE CAR WOULD NOT START UP. I HAD TO GET IT TOWED TO MY HOUSE. AFTER SITTING FOR THE DAY, I TRIED TO START IT UP AGAIN AND IT STARTED. I WAS ABLE TO MAKE IT TO THE ADVANCE AUTO NEAR MY HOME WHERE THEY PUT IT ON THE MACHINE TO SEE IF THERE WAS A PROBLEM WITH THE ALTERNATOR AND/OR BATTERY. ALTERNATOR WAS GOOD AND THE BATTERY HAD SOME DEAD CELLS BUT I WAS TOLD NOT ENOUGH FOR THE CAR TO JUST DIE OUT IN THE MIDDLE OF DRIVING. THE NEXT DAY I INSTALLED A NEW BATTERY, THE CAR STARTED, DROVE ONTO THE INTERSTATE AND IT STALLED AGAIN (MY DAUGHTER WAS IN THE CAR) I HAD TO DRIFT TO SERVICE ROAD. I HAD TO LEAVE THE CAR OVERNIGHT, WENT BACK THIS MORNING (WEDNESDAY)AND THE CAR STARTED, I DROVE DIRECTLY TO THE INFINITI DEALER AND WAS DIAG.W/A BAD CRANK POSITION SENSOR. I HAD IT REPAIRED. I RESEARCHED THIS PROBLEM THE FIRST DAY IT HAPPENED AND FOUND THAT A RECALL WAS IN PLACE FOR OVER 620K M45'S;HOWEVER MINE WAS NOT ONE OF THEM. SAME PART, SAME DIAG, SAME MODEL, DIFFERENT YEAR. THIS IS DEFINITELY A HAZARDOUS PROBLEM AND I AM SEEKING REIMBURSEMENT FOR THE FEES I PAID TODAY ALONG WITH SOMEONE LOOKING INTO RECALLING THIS PART IN THE M45 MODELS. ITS RIDICULOUS NOT TOO IF THE SAME PART HAD TO BE REPLACED IN A 2004 WITH THE SAME DIAG. AND NOT A 2003. IF THIS IS NOT THE CORRECT DEPARTMENT I NEED TO FILE A COMPLAINT WITH, I NEED TO KNOW WHO CAN REALLY LOOK INTO THIS ISSUE. LUCKILY, NO ONE WAS HURT IN MY SITUATION BUT IT IS BOUND TO HAPPEN BECAUSE GOING HIGHWAY SPEEDS WITH YOUR CAR COMING TO A SLOW PACE INSTANTLY CREATES A VERY FRANTIC SITUATION. *TR

ELECTRICAL SYSTEM PROBLEM
- Date Of Incident: 2010-05-07
- VIN: JNKAY41E24M
- Components: ELECTRICAL SYSTEM
- Summary: PURCHASED A 2004 INFINITI M45 WITH 76K IN MAY 2010. WITHIN 2 DAYS OF BUYING THE CAR THE CHECK ENGINE LIGHT CAME ON. I HAD IT SCANNED AND IT SAID "FUEL SENDING UNIT" SO I REPLACED THAT PART AND THE LIGHT WENT OFF. ABOUT 2 DAYS LATER, THE GAS TANK WAS ABOUT 1/4 TANK SHOWN, AND I WATCHED THE FUEL GAUGE NEEDLE MOVE FROM 1/4 TANK TO "FULL" AT THE STOP LIGHT. SHORTLY THEREAFTER THE CHECK ENGINE LIGHT CAME BACK ON. I DID A QUICK "GOOGLE" SEARCH AND FOUND MULTIPLE ONLINE FORUMS DISCUSSING THIS TOPIC AND THE REAL FAULT IS THE GAUGE CLUSTER. I CONTACTED A LOCAL INFINITI DEALER AND ASKED ABOUT THE PROBLEM AND WAS TOLD "IT'S ONLY HAPPENED A FEW TIMES" BUT I HAD PAGES OF OTHER OWNERS POSTING ON THE FORUMS SAYING IT HAD HAPPENED TO THEM. THE DEALER TOLD ME IT WOULD BE $800 TO REPLACE THE GAUGE CLUSTER, SO I SAID "NO THANKS" AND HAD MY ORIGINAL CLUSTER REPAIRED WITH A LIFETIME WARRANTY AT BBA REMANUFACTURING AND IT HAS WORKED PERFECTLY SINCE SEPTEMBER 2010. PRIOR TO REPAIRING THE ORIGINAL ONE, I PURCHASED A BRAND NEW GAUGE CLUSTER ON EBAY, BUT IT WAS NOT FOR MY MODEL WITH ICC AND NAV, SO I HAVE SPENT MONEY BUYING A GAUGE CLUSTER AND REPAIRING MY ORIGINAL ONE. *TR

FUEL SYSTEM, GASOLINE PROBLEM
- Date Of Incident: 2009-02-09
- VIN: JNKAY41E94M
- Components: FUEL SYSTEM, GASOLINE
- Summary: MY FUEL GAUGE READ 1/3 OF A TANK AND I RAN OUT OF GAS. I BOUGHT THE CAR USED IN APPROXIMATELY JAN 2009 AND I BOUGHT AN EXTENDED COMPLETE POWERTRAIN WARRANTY. THEY INITIALLY THOUGHT IT WAS MY FLOAT MECHANISM IN THE GAS TANK BUT FINALLY REALIZED IT WAS THE DASH AND REPLACED IT UNDER WARRANTY ($50 DEDUCTIBLE APPLIED). MY WARRANTY EXPIRED A FEW MILES AGO (CAR HAS 90500 MILES ON IT NOW) AND I HAVE BEGUN TO NOTICE THE PROBLEM AGAIN. CURRENTLY I FILL UP AFTER THE TRIP ODOMETER REACHES 300 MILES DRIVEN ON A TANK BECAUSE WHILE THE GAUGE APPEARS TO WORK ACCURATELY, ONCE IT REACHES 1/4 OF TANK LEFT, IT BEGINS TO RISE AND WILL GO AS HIGH AS 3/4 FULL. SOMETIMES TURNING THE CAR OFF AND THEN BACK ON WILL RESET IT BUT IT WILL SOON BEGIN TO RISE AGAIN. VERY ANNOYING AND ACCORDING TO THE DEALER THE DASH COSTS $900+ (IN 2009). RAMSEY INFINITI OF RAMSEY NJ DID THE WORK IN 2009. *TR

- VIN: JNKAY41E24M
- Components: FUEL SYSTEM, GASOLINE
- Summary: WHILE DRIVING VEHICLE THE FUEL GAUGE AND FUEL REMAINING COMPUTER SHOWED A SIGNIFICANT AMOUNT OF FUEL LEFT, ALMOST HALF A TANK. AFTER A COUPLE OF MINUTES OF DRIVING THE CAR SPUTTERED AND STALLED. I PULLED OVER AND TRIED CRANKING THE MOTOR. AFTER SEVERAL FAILED ATTEMPTS I NOTICED THAT THE FUEL GAUGE WAS NOW SETTLED ON EMPTY. CHECKED THE COMPUTER AND IT SHOWED 0 MILES TILL EMPTY. LUCKILY MY WIFE WAS ABLE TO BRING ME THE GAS FOR THE LAWNMOWER. THIS HAS HAPPENED SEVERAL TIMES SINCE THIS INITIAL INCIDENT. A COUPLE TIMES WITH JUST MY WIFE AND CHILDREN IN THE CAR. FORTUNATELY MY WIFE'S COMMUTE INVOLVES STREETS AND AVENUES AND NO FREEWAYS OR HIGHWAYS. I'VE COMMUNICATED MY ISSUES ON FORUMS AND BLOGS, TURNS OUT THIS IS A COMMON PROBLEM, AND SO FAR NOTHING HAS BEEN DONE BY INFINITI TO ADDRESS THIS. THE FIX COMES AT A RIDICULOUS PRICE, DEALER WANTS TO CHANGE OUT GAUGE CLUSTER, UPWARDS OF $1,000. I'VE BEEN USING THE KEEP IT FULL METHOD, SINCE I LIKE THE CAR, OF COURSE I SHOULDN'T HAVE TO BE DOING THIS. I DECIDED TO FILE THIS REPORT AFTER READING THAT THE NHTSA WAS LOOKING INTO THE ISSUE. THANK YOU. *TR
FUEL SYSTEM, GASOLINE,ELECTRICAL SYSTEM PROBLEM

- VIN: JNKAY41E34M
- Components: FUEL SYSTEM, GASOLINE,ELECTRICAL SYSTEM
- Summary: I RAN OUT OF FUEL ON A BUSY HIGHWAY IN STOP AND GO TRAFFIC BECAUSE THE FUEL GAUGE REGISTERED FULL WHEN THE TANK WAS ACTUALLY EMPTY. THESE GAUGES HAVE MAJOR INTERNAL ISSUES RESULTING IN WHAT MAY BE A SERIOUS SAFETY CONCERN. *TR I'M NOT THE ONLY ONE (LINK BELOW) AND WE ARE GRATEFUL TO YOUR ORGANIZATION TO ADDRESS THIS TO THE BEST OF YOUR ABILITIES: HTTP://FORUMS.NICOCLUB.COM/M45-FUEL-GAUGE-PROBLEM-POST-HERE-IF-YOU-HAVE-HAD-IT-T316682.HTML. *TR
FUEL SYSTEM, GASOLINE PROBLEM
- Date Of Incident: 2011-08-01
- VIN: JNKAY41E54M
- Components: FUEL SYSTEM, GASOLINE
- Summary: THIS CAR DIED ON ME ON THE HIGHWAY WHEN THE FUEL GAUGE SAID THAT I HAD A 3/4 TANK OF GAS REMAINING. THE CAR STARTED SPUTTERING LIKE IT HAD RUN OUT OF GAS SO WE ADDED GAS AND IT STARTED RIGHT UP. I DROVE IT TO A LOCAL INFINITI DEALERSHIP RIGHT AWAY. THEY DIAGNOSED THE PROBLEM AS IN INSTRUMENT CLUSTER, WHICH SHOCKED ME AS I HAVE NEVER HEARD OF AN INSTRUMENT CLUSTER BEING RESPONSIBLE FOR A CAR RUNNING OUT OF GAS. I SEARCHED SOME ONLINE FORUMS ONLY TO DISCOVER THAT THERE WERE HUNDREDS OF OTHER PEOPLE WHO HAD THE SAME PROBLEM. HAD THE FUEL SENDING UNIT OR FURL PUMP WENT OUT, THAT WOULD BE UNDERSTANDABLE, BUT THE INSTRUMENT CLUSTER GOING BAD COULD HAVE BEEN VERY DANGEROUS. SINCE THE CLUSTER CONTROLS MILEAGE AND ALL THE WARNING LIGHTS SUCH AS CHECK ENGINE LIGHTS, THIS WAS VERY SCARY. IT SEEMS THAT INFINITI KNOWS THERE IS A PROBLEM WITH THESE AS MANY OF THE PEOPLE ON THE FORUMS SAID INFINITI HAD PAID FOR A NEW INSTRUMENT CLUSTER. WITH THIS PROBLEM BEING SO PREVALENT, I THINK IT IS VERY IMPORTANT FOR THE NHTSA TO LOOK INTO. I BELIEVE IT SHOULD BE A RECALL WITH THE NUMBER OF PEOPLE HAVING PROBLEMS. ALTHOUGH MY ISSUE HAPPENED AROUND 90,000 MILES, THERE WERE MANY OTHERS THAT EXPERIENCED THE PROBLEM AT 30 AND 40,000 MILES. *TR

Positive 2004 Infiniti M45 car reviews

The car handles very well and has plenty of power. The navigation system performs well. The intelligent cruise control works amazingly well, even in traffic. However, in Southern California, it maintains a safe separation distance, which means other drivers frequently cut in front.
-
Hey there! Thanks for sharing your feedback with us. We're sorry to hear that you're experiencing some trouble with the transmission. We appreciate your honesty and we'll do our best to address this issue for you. Please let us know if there's anything else we can do to help!

For $40k, this is the best V-8 deal available. It's incredibly fast, yet surprisingly quiet. The dealer is great, and the warranty is better than average. Plus, there are plenty of interior features to enjoy.
-
I've been driving the Infiniti M45 since September 2004. It's got plenty of power with smooth acceleration and a great braking system. The interior design is very well done, with almost all of the fancy features you can think of.
-
I haven't loved a car this much since my '88 Mustang Conv. GT. The 2004 M45 is fast, comfortable, and hot with all the jazz. I stopped talking to the car after two weeks (voice activated stuff is cool but useless once you know what to push). In a car with this much electronics and intelligence, the analog clock is a wonderful touch. The interior is gorgeous.

Are you having problems with your 2004 Infiniti M45?
Jonatan Emmerich 2024-07-24
I see you've moved from an I35 to an M45! That's quite an upgrade! It sounds like you're enjoying the car's horsepower and acceleration, especially after 55 miles an hour. I'm glad to hear that you're happy with the handling, but it's a shame that the back seat doesn't have more leg room. I agree that it would be helpful if the cruise and radio controls lit up at night, and it would be convenient if the doors locked and unlocked automatically when moving from park. It seems like the price of the car should include more standard features, but overall it sounds like you're enjoying your new ride!
