2003 Infiniti M45 Navigation 4.5L from North America
Various interior lights.
Tire pressure sensors.
Gas gauge misreading.
Nice car. Classic style. The parts on this car are ridiculously expensive. So become best friends with your scrap yard and mechanic.
Not many aftermarket parts, so Infiniti dealer parts high prices are unavoidable sometimes. Way too many sensors for everything makes simple repairs difficult.
People complain about the build quality. It's a 10 year old car! A high original price doesn't mean better overall quality!
My advice is buy this car as cheap as you can and use the money you saved for future repairs. The transmission can be sluggish. Changing your fluid does wonders.
Great power, still a 340 HP V8, still pulls hard. Seats are very comfortable. Interior is holding up well. Always get compliments on the car. Not too many around.
M45 running costs are high. Consider other models if you want cheaper.
Would you buy another car from this manufacturer? Yes

Nice review :) You get it ;)
You will never go wrong changing transmission fluid (and filter) early and often. The only caveat being getting a shop who actually changes the fluid, and uses decent quality fluid/filters.

I actually did it myself. The fluid costs $12 a quart. I did a drain and fill. Took 4.4 quarts. Nissan type J fluid.

Excellent - early and often indeed!!!
Keep that up on an annual basis, and that tranny might live ;)
I say annual, as you are only replacing a fraction of the fluid. I'm nursing a 1999 Accord V6 that way, and it still hangs in there.

I just got the gas gauge repaired under recall. Be persistent with Infiniti and the dealership you chose to do the recall. Took 7 weeks of back and forth to get the job completed. Finally done :)

Still have my M45. Fixes needed... ABS sensor, driver's side strut mount, rear trunk struts, and lower control arms.
Just fixed the radiator ($200 aftermarket).
346,000 km on the car now. Still going!

Great bang for your buck car. In my area of southern California, they are going for peanuts. But the secret is buying a one owner car if you can with maintenance records. There are a few of them left out there. Common problems to that model, so you have to make sure it's already been fixed or the price adjusted so you can do the work yourself.
This is an amazing time for car lovers who have limited income and the ability to watch YouTube fix it videos and can turn a wrench. Most modern cars today are basically plug and play. So if you can put the square peg in the square hole... you can work on these cars.

M45's are holding up well in Canada, even with all the salt here.
Maybe because the car has real metal and weighs 4000lbs. Rusting away slowly LOL.
I had a 2002 Infiniti G20 and the body didn't hold up as well.
