Tranny problems with 7k miles

Maybe it's not too late!

Hi,

first post so just let me get started...
I live in Qatar and I bought the FX50s a year ago and I'm having endless problems with it....

First problem was jerking when the tranny upshifts or downshifts, also jerking happens when I ease my foot of the throttle trying to maintain constant speed. Since I bought that model very early in its life cycle, Nissan/Infiniti were clueless about what to do regarding the jerking, it was more of fuel cut off issue just between shifts that makes your car stalls for a fraction of a sec which feels like engine hesitation .... after 8 months they figured out that the electronic motors/sensors that open and close the exhaust valves were malfunctioning and they said that it was a quality control issue!!.... I got them replaced and now the car is find.. well sort off, I think the damage has been done!!!

Problem is that i drove my car with the jerking problem for 8 months that's equivalent to 40k Km or 25k miles in my book and now the car is unable to accelerate gently.. it's not registering the first few angles of the throttle and just moves very slowly,, when I try to press my foot just a little bit more to have proper acceleration, the car just jumps. also shifting is very rough most of the time,, it's like this tranny doesn't have a clutch/ torque converter... sometimes i feel like I'm shifting a manual tranny without using clutch.. it's rough..........

I'm demanding Nissan/Infinit for a new replacement since it wasn't my fault to put those faulty motors in my car nor it was my fault to driving my car for 8 months without any solution from them......


just couple of days ago Nissan contacted me because i wasn't satisfied with the car and they offered me a new improved ECU and I took that offer. after replacing the ECU, the car is still the same,, maybe there was a slight improvement but it looks like they were trying to override the problem with the software and trying to mute it down, but that's not a solution is just that they are trying to hide the problem and keep my car run as long as it can with this problem ( I guess their target is to push me out of warranty )....

Anyway, not solving this shifting problem by replacing the ECU wasn't the only problem, now I have another problem..... when I switch on the car/engine the engine stalls!!!!!!!!!!! I have to keep my foot on the throttle not to let the RPM goes as low as 300 RPM!!!! this is very frustrating,, they treat me as if I'm their test driver or something they offer me unproven solutions and they are not giving me anything back.. I really have it with this car, just want to get a new car don't want to go any longer with this lemon........

if you have the same problem as mine,, just don't drive your car with that jerking,, stop driving it and don't do any further damage to your power-train. contact your Dealer and tell them about those exhaust gas motors.

Wow!

Hey Falcon, I am really sorry to hear that. I am extremely surprised hearing that a Japanese car is doing that. I bought my FX50 instead of an X5 4.8 just because I always knew that Japanese are very reliable cars. My brother and my parents have been driving Japanese luxury for quite some time now, and they never had any MAJOR problems like yours.
My previous car was a BMW 330xi and I had constant problems towards the beginning, including a recall on a cooling fan (which I actually found out while driving the vehicle and saw my engine temp going up!).
So once I got rid of the German, I decided to go Japanese, and I've had it for a year so far, and the FX50 hasn't had any major problems YET!

From the sound of it, it seems to me that you had the misfortune of obtaining a "lemon", which really sucks balls! I would persist in getting Infiniti to help you out with the problem. Keep in mind, that Infiniti is an up and coming luxury brand (been around for about 20 years now) and they are not in any position to taint their brand. They do not have decades of heritage like BMW, Porsche, or Mercedes-Benz, so I would assume that if they are threatened by having a bad reputation, they would probably try to do something about it. See if you can contact the headquarters in Japan.

I wish you the best of luck and happy new year!:tup:
 
Guanche01,

Thanks for your kind reply. I previously talked to Nissan workshop manager and told him that i can't keep going back and forth between my house and the dealer just to try some unproven solutions and I demanded a new car, I know that the problem lays down somewhere in the tranny. Looks like the manager was taking me seriously and he said that they are thinking about that and they will offer me a new car if this issue isn't resolved.

I know Japanese cars are reliable, but you have to know that Nissan/Infiniti aren't as conservative as Toyota/Lexus. Nissan/Infiniti take risks and push their design to the limits more than Toyota/Lexus dare to do. This is why I chose Infiniti over Lexus.

happy new year 2010!!
 
Falcon:
your problem seems to be similar to mine. When i started the car and shift to D the engine stalled. It was the torque converter, but they doesn't deliver it alone, so I had to buy a new tranny assy. My car is running Well right now after spending 15k in labor and parts. What angers me is not the warranty coverage. What angers me is that my car broke up with 7k miles. And i insist that other brand gives me more solutions than Infiniti.
 
How I found this post: I Googled "Infiniti FX50s problem with tranny" ...this thread was the first search result.

I currently have the EXACT same issue with my 2009 FX50S. Leased it in September of 09. Drove from FL to NY for the holidays in Dec. Problem described above started about halfway to NY. Then the whole way back... brought it back to Infiniti of Palm Beach five times for this exact problem. I got every line of [bleep] from the service reps from "not being able to duplicate the problem", "the cars computer has to learn the driver, so once it does, a different driver will make the tranny shift differently... to the latest... "it's normal!" Yes, you read right... now their trying to tell me that all of the seven-speed tranny's do this. When I ask "if it's normal, why doesn't it do this ALL the time?" --- they have no answer at all. On top of all of these BS excuses, they've also installed "black-box-type devices" and worked with off-site engineers to help, with the only solution they could muster up being a couple software updates along the way.

After all of this nonsense, the car was still bucking / hesitating / stalling, whatever you want to call it... so I spoke with an attorney that specialized in FL Lemon Law... I was told at the time, that if the car was back to the dealership more than 4 times for the same problem, it was automatically a lemon under FL state lemon laws. Problem is, I really loved the car, and I only wanted to go this route as a last resort. The problem got better over a month or so, and eventually went away. Then the holidays came around again, and we made the same trip. On the way, it started doing the same thing all over again. Brought it to the dealership, with all the same lazy, incompetent answers. Getting the car back tomorrow, with absolutely nothing accomplished at all.


What aggravates me the most is that I love the product, I have never heard of any issues like this in the past, whether it be mechanical, customer service related, etc. Ive contacted consumer affairs and they do nothing except take your complaint, ask you what you want them to do, and even after saying to them, "all I want is a new vehicle for the rest of my lease, or out of the lease so I can get a different car"... their only resolution offering has been "sorry, we cannot honor your request, but we can give you free oil changes" -- tell me I'm dreaming?!? This is borderline criminal. I pay $880/mo for this car... Ive had better customer service from much more expensive cars, and much more affordable cars as well... I guess I'm going to have to go the attorney route. Blows.

I know your post is from '09, but what is the current status of your FX50S? Hopefully, you've found a solution... :wink (2):

There is currently no resolution to the hard shifting on the 7 speed auto transmissions. All Infiniti's equipped the the 7 speed transmissions suffer from this. Nothing you can really do about it right now. From what I've heard, Infiniti is currently making a new software programming to correct this as we speak. Just got to be patient and wait :-)


It's not a transmission problem though. It's just glitchy software that needs worked out.

Again, I'm not talking about a hard shifting tranny. This is not a normal issue. It comes and goes. A car that feels like it's being hit from behind in the middle of driving 70 mph on the hwy isn't safe, nor acceptable. I'm guessing I'll have to go see an attorney again. No resolution anywhere Ive searched online either... Oh well, I'll have to go back to BMW... yeah, they have issues, like any highl-tech modern car, but at least they fix them. :eek.:

Update:

After going back and forth with Infiniti Consumer Affairs, and getting nowhere with their robot-speaking supervisor of all of Infiniti USA "Shawn Bennett" I started to contact attorneys for fighting this under the FL state lemon law. (which I clearly qualify for, just didn't want to go this route unless I absolutely had to)...

After hearing every excuse in the book from "it could be bad gas" to "it's normal" Ive just had it up to eyeballs with disgust and frustration. I'm paying (leasing) $881/mo for a $61k crossover that bucks like a 1985 station wagon. Unacceptable. I am officially anti-Infiniti. I gave them more than enough chances.

I found out today, (from the GM at my local dealership) that the new M had the same exact issues... and guess what? They FIXED it... because too many people were complaining and returning them right away... The FX50 is rare in comparison to the FX35, and G's, M's, etc... So why LIE and tell me it's NORMAL? It's not F'ing normal! There isn't a chance in hell that me or anyone else would ever buy this car if we felt this "bucking" on our test drive. if it's normal, than why did they fix it in the M? So ridiculous... I'm just so mad that a company I loved and promoted so much - as one of the best auto makers in the world... is treating me so terribly.

The only "solution" that Infiniti / Consumer Affairs has offered me to date, has been free oil changes. WOW.

I'm done. Attorney hired, will post outcome as soon as I get one.

In the meantime, stay away from the FX50, and the new QX56 has the same issues, yet to be resolved as well...

:mad.:
 
Sorry to hear your not satisfied. I hope everything works out.


But telling someone to stay away from an FX on an FX enthusiast community forum is plain silly.


I guess people must not really care about the same things you think since the new QX and M sales have sky rocketed in the past half year.
 
I was simply saying to stay away fro the FX until they fix the issue... (which they never will if everyone with this issue just sits around with their thumbs up their a**es chatting about it in a forum) - Don't listen to me... I could care less... your the one that's going to have to deal with the issues. (for the record: I still have 3 Infiniti's in the family, just no other FX's)

The GM at my local dealership said that half of the QX's sold are being returned, and the M's have already been fixed (hence sales went up over the last 6 months)

Don't get me wrong, I love the car, aside from this issue and how poorly Ive been treated from Infiniti. Do you understand? I'm leasing this vehicle. It's fully covered under warranty. They are NOT fixing it, or replacing it, or anything that may be related to the issue... they are actually trying to tell me that it is "normal!"

I don't think you could possibly have any idea how bad this problem is. Imagine... you just picked up a brand new 2011 Infiniti FX50S... your driving home, and the tranny starts bucking... as if someone is bumping into your rear bumper on the highway going 70-80 mph... would Lexus put our a product like this? BMW? Mercedes? The answer is HELL NO! And neither would Infiniti (in the past)... I'm disgusted... Never in a million years would I expect to be treated this way from such a great manufacturer...

This has been going on for 18 months now... I'm done with this POS!
 
Well I do hope they sort out your problems though. This issue doesn't sound common since yours is a 50 and not too many 50 owners on here. None the less I hope everything works out for you.

Thanks, I appreciate that... but unfortunately I've exhaust my options. I have to go with a manufacturer that is going to stand behind their (top of the line) model vehicles warranty. They are basically telling me to go F**k myself. Not cool. :mad.:

I don't have the problem u are describing. Did u go on a test drive with the mechanic? What I are describing is not normal. Sounds like u have some unique problem that they are just saying normal because their tests read normal and if that is the case, I would go to another dealer or even 2 other Infiniti dealers.
 
I bought my FX50 two months ago and so far so good... I would definitely go to another dealership. Service experience can be night and day, shouldn't be, but that's what I've found.

Good luck!
