I blew a head gasket on my 2006 M35X. It had over 200K miles, so I will give it a pass. But along the way, the car ate wheel bearings like candy (3 up front). Had to replace the propeller shaft, both CV joints, the exhaust system at 150K miles. Also the car had huge rust holes in the frame and I don't live in an area that uses a lot of salt on the roads.

I also had a 1992 Lexus LS400 which eventually had 300K miles before the transmission went. NOT a dime spent on anything else except brakes and tires. The stainless exhaust system was still tight at 300K miles. NO mechanical issues at all.

But I will admit I liked my M35X, so I got a 2013 M37X that was built fairly late in 2013. Got it with 55K miles. It has 64K miles now. Have replaced both front wheel bearings. And NOW I have a major exhaust leak and when I looked under the car, yep, it was rusted out. Who makes a luxury car without a stainless exhaust in this day and age? Nissan does! JUNK

SO, now I'm looking to replace the exhaust. FOR SURE, I will not be using a Nissan crap replacement. Does anyone know where to get a genuine stainless steel exhaust that won't break the bank? Also is it normal for the transmission to be a little clunky getting into second and third once in a while? Sort of a slip and jerk.

Sucks you've had issues...I had the complete opposite experience with the brand and if Nissan/Infiniti were still innovating like they used to, I'd keep buying them. Unfortunately, with them falling behind in tech and completely killing the Q70, this may be my list Infiniti sedan.

For the exhaust, your best bet is a custom exhaust cause if you go Stillen, ArK, etc. you're paying for R&D and name.

Thanks for the advice on exhausts. Going to put on a lift in the next couple of weeks to see what all needs replaced. Will also treat other frame rust while the car is in the air. Nissans have been rust buckets since the Datsun days. Almost famous for the rust. Would think they would follow the lead of Honda and Toyota on this. Early Hondas were rust buckets too. My '76 Civic and '79 Accord both rusted out. Never had an issue with Hondas after that. Thank God for rust converter! LOL

I will say that I also have some surface rust on my '12 M56x, mainly on the frame work as you described. I bought mine used in 2015 with 52k miles. It spent that time in White Plains, NY so I guess I can understand why my car had the rust. Yeah the exhaust was also rusted but not all the way through. One of the first things I did was replace it anyway. I went back with a custom exhaust like Ilya suggested. Got rid of the Y-pipe/secondary cats and resonators to open it up and went with an X-pipe and sport mufflers. I primed and painted mine with VHT high temp ceramic spray paint before putting it on. Still looks great after 5 years. I haven't had any mechanical issues so far, I'm at 122k miles now.

Yeah I have some surface rust too on the underside (control arms, etc.) but my exhaust, even after 130kmi of which 90kmi is in upstate NY winters, is still intact and not in need of replacement. My body rust is fine except for a few spots above the windshield but those are from rock chips that I didn't get taken care of...not sure what to do with it because I'm told I'll need to pull the windshield to do it correctly.

My car is nearly 10 years old and unless you're standing 5ft from it, it looks brand new. That's impressive. Cars rust...I expect to get rid of this car from that kind of stuff before I do because the engine or tranny gave out...

People will say, all cars rust and to a degree that is true over time. But not to the same degree. Infiniti is a luxury car. I have higher expectations. Have owned a Acura Legend, 2 LS400's. They didn't rust. Their exhausts lasted 100's of thousands of miles. I've had two Infinitis. The bodies looked fine, but the frame and exhausts rusted through. Why would they sell a luxury car without a galvanized frame and a stainless exhaust? Why is that? Other manufacturers build their cars like the owners will have them a long time. Nissan has chosen not to. BMW is just as bad. They don't care about long term reliability. They cater to the folks that buy new cars. To the detriment of people like me that drive the wheels off cars. LOL

One the LS500 is obtainable im switching to that. I love Infiniti also but they seem to be very lazy when it comes to tech.

Same. The 460 has been my dreamcar for ages and now that the 500 is out I see one of two things happening:

1) Get a 2019 Q70 5.6 for another 5-6 years to replace my aging '11 M56x
2) Get out of Infiniti sedans completely and replace my '11 M56x with an LS500

Either one, I'm expecting, to happen in the next 3-4 years as I plan to drive this car as long as I can before it becomes fiscally irresponsible to keep it running. Love my car. Has given me no trouble other than the battery issues and cat issue (which I solved, at least for now). All original body/panels/suspension/interior/electronics, etc. and running like a champ.

I've had good luck with nissan cars, no rust either, but I live in the south

i understand quite a few people want that big Lexus , big reputation spotless brand name , great specs....until u drive it .
I checked Lexus LS every time before buying another Infiniti Sedan [ i have purchased 6 of them ] never got past driving it , if u liked 1968 Cadillac you will love the LS.

That's odd the ls430 and the ls460s I drove felt better than any Infiniti I have ever driven. The Lexus is just out of my price range. to each their own.

that is why they make 50 different brands each to his own
