2000 Infiniti Q45 problems
The Infiniti Q45 is a full-size luxury sedan manufactured by Nissan for its Infiniti brand, spanning model years 1989-2006 and three design generations.
The first generation Q45 (1989–1999) was based on the Nissan President; the second generation (1997–2000) and third generation (2002–2006) were based on Nissan's JDM Nissan Cima. Marketing of the Q45 ended after MY 2006.
First generation (G50; 1989–1996)
The first generation Q45 came to market in 1989 as a 1990 model with a high-output 4.5 L VH45DE DOHC 32V V8 engine rated at 278 hp (207 kW) and 292 lb⋅ft (396 N⋅m) in North American trim. All Q45s included a viscous limited-slip differential and a multi-link suspension at the front and rear. At launch, the US$38,000 (equivalent to $93,000 in 2023) sedan had a single option, the Touring Package, which added Nissan's Super HICAS four-wheel steering system, a decklid spoiler, and alloy wheels.
In Japan, it was marketed as the Nissan Infiniti Q45, and was exclusive to Nissan Prince Store locations, as its platform twin the President was exclusive to Nissan Store locations. The G50 chassis continued in production in Japan until 2002 as the President in both regular and extended wheelbase versions. The Japanese version had many options that never appeared on the North American G50.
The contemporary upstart luxury marque Lexus (Toyota) had managed to challenge the establish dominance of European full-size luxury cars with the LS 400, so the Q45 seemed poised for similar success with comparable specifications and price to the LS 400 while featuring more emphasis upon handling. However, the Q45 did not achieve similar sales volumes, which was attributed to the car's unconventional styling, particularly the grille and lack of interior woodgrain or chrome trim. There was also an unusual advertising campaign which did not include actual photos or information about the car. By 1995, the price had risen to US$54,000 (equivalent to $108,000 in 2023), slowing sales.
In 1993 the Infiniti brand was launched in Australia with the sole model on offer being the Q45. With a price of A$140,000, the Q45 sold poorly and the brand was subsequently withdrawn from the market in 1996.

SUSPENSION,TIRES,WHEELS PROBLEM

SERVICE BRAKES, HYDRAULIC PROBLEM
- Date Of Incident: 2007-04-07
- VIN: JNKBY31A1YM
- Components: SERVICE BRAKES, HYDRAULIC
- Summary: MY 2000 INFINITY Q-45 WITH 37,000 MILES OF USAGE SUDDENLY AND WITHOUT WARNING COMPLETELY LOCKED UP WHILE UNDER POWER IN THE OUTSIDE LANE WHILE ON A BUSY SIX LANE STREET AND WOULD NOT MOVE. THE VEHICLE WE LATER LEARNED BY THE DEALER HAD SUFFERED A REAR WHEEL BRAKE AND AXLE COMPLETE BREAKDOWN AND FAILURE. THE DEALER SERVICE DEPARTMENT SAID THAT WE MUST HAVE DRIVEN THE CAR WITH THE EMERGENCY BRAKE ENGAGED TO CAUSE THE AXLE, BRAKE LININGS AND DRUMS TO OVER HEAT AND FATIGUE. THE CAR REQUIRED A SIGNIFICANT NUMBER OF NEW REPLACEMENT PARTS IN THE ACEL/BRAKE ASSEMBLY AREA THAT REQUIRED $2,158.64 IN PARTS AND THE TOTAL BILL WAS $3,113.70. WHILE NO ONE WAS INJURED IN THIS EVENT, IT WAS ONLY BECAUSE THE INCIDENT OCCURRED ON A SURFACE STREET A LOW SPEED AS OPPOSED TO AN INTERSTATE HIGHWAY. MY CONCERN IS THAT WE, THE DRIVERS OF THE VEHICLE THAT WAS PURCHASED NEW, ARE RETIRED AND MONITOR OUR VEHICLES CLOSELY. THERE IS A "INDICATOR LIGHT" THAT SHOULD COME ON AUTOMATICALLY WHILE DRIVING OR ATTEMPTING TO DRIVE WITH THE EMERGENCY BRAKE PARTIALLY OR FULLY ENGAGED. THIS NEVER HAPPENED.

This car is truly underrated in the market. I was fortunate enough to purchase this top-of-the-line off-lease vehicle at a reasonable price. Its sleek and elegant-yet-aggressive design, combined with its more-than-ample power (266 hp) and confident, comfortable performance (17-inch tires), make it an absolute pleasure to own. The cabin is world-class, offering ample space, luxurious features, and high-tech gadgets such as GPS. I receive compliments almost everywhere I go, which is always a welcome surprise. It's also refreshing to drive a unique car, as while Lexus, BMW, Mercedes, and others are superb, they are too common and too costly.

I bought the car in 1997 when it was just 2 years old with 36 K miles. It was an amazing driving experience! The car has a unique presence, is incredibly roomy inside, has comfortable seats, and great pick-up without a kick-down. The customer service was excellent, even though it wasn't exactly cheap.

Best of both, you get lots of luxury with sporty features and performance.

Great car! It's really fast going from 30-65 and it's so much fun to drive in moving traffic. The car handles really well with good acceleration and the sound system is amazing!

Hi there! I hope you're doing well. I just wanted to share my experience with my car. I bought it back in '04 with only 39520 miles on it, and it's been a great ride ever since. The only thing I had to replace were the tires due to some road noise, but other than that, it's been smooth sailing. While it may not have the most powerful engine, I find that the ride more than makes up for it. Before this car, I used to drive SUVs and trucks, but I've really come to appreciate the comfort of a car for both highway and street driving. I'm actually considering getting a new Q45, mainly because of the stronger engine. If only someone could install the 4.5 liter in my old Q45T, I'd definitely keep it! Let me know if you have any questions or thoughts on this.

Great riding car! It's super comfortable and has a large, boat-like plush ride. It's awesome as a family car or cross country cruiser. However, I did have some problems with an oil leak. Thank goodness I purchased it under warranty.
