[2011+] QX56 new motor, timing chains, etc

Success! After waiting 10 days, talking to Infiniti Consumer Affairs who then called the dealer, they agrees to forgo the "diagnostic charges" and begin the work on my car. I had caller the dealer where I bought the car in NJ and they said no problem bring it in! They've been dealing with this issue regularly and told me my warranty covered it in full. This may have prompted the MD dealer as I had told them I would have the car towed to NJ to have the work done there. I shouldn't have had to wait 10 days!
 
Sorry to hear you had to go through all that just to get them to work on you SUV. The positive side is they are finally doing something about it.
Although I do agree you shouldn't have had to go through what you did.
 
@Rod... which MD dealership was that?? I'm in Columbia area, JBL Infiniti is tops, I heard Nationwide in Timonium is pretty good too
 
I have found myself in the same situation and thought I would post here to see what pointers you could give me in trying to get Infiniti to repair the known issue on my QX out of warranty. I'm at 73K miles. The dealership has been good so far but Infiniti Consumer Affairs has told me "sorry your out of warranty". Not going to do anything for me. I've asked to speak with a supervisor but have yet to receive a call.

Any help or pointers you could give me in turning this into a positive outcome is greatly appreciated!!

They just told me the oil pressure jet or jets failed and that is the problem.

When I bought my 2011 Certified with 17k I specifically called the Service Manager to confirm that the manual was correct. The QX56 manual recommends changing the oil every 7,500mls under normal or average driving conditions... Could the manufacturer of the vehicle be wrong?
 
no.

conventional oil technology have improved over the years so 7500 miles is good. the main thing is to be consistent and change the oil frequently.

if you tow a lot of drive your car hard or live in dusty conditions, change it a little more frequently.

i get my oil changes at infiniti and they are on record, so if anything happens, i have my oil change intervals documented.
 
If 7500 is good enough.. why am I being told my the dealer to change it every 3500 miles.. I change it every 4-5k, only because I put 3500 on in 6weeks, I can't be in the shop every 6 weeks.. that's nuts.

And , why doesn't Infiniti use Synthetic oils?
 
do whatever the book recommends and/or your dealer. the point is to be consistent.

the local dealer i use recommends 3500 but i go at 3000K because im old school.

any infiniti dealer should have synthetic oil avail to use--just ask. i have a warranty that pays for oil changes and they use conventional oil. i could pay for synthetic but its not necessary as long as i change the oil and filter at the specified time.

I was just told that my timing chain on my 2011 QX56 is now in need of being replaced. I haven't been quoted a number yet. At 45,000 miles I had to have a whole new motor for this same issue! This truck has been a nightmare from the beginning, stranding my wife and family on numerous occasions. We don't live near the Infiniti dealer which has complicated things tremendously. I am scared to death I will be facing a very expensive repair. I already have an catalytic converter issue that the dealer has quoted me $3400 to replace/repair, and now this--for the second time! Has anybody considered a class action lawsuit against Infiniti? As owners we need to stand up and do something. This is completely unacceptable for a $70,000 truck.
 
there are lemons/defective cars produced on assembly lines all across the world. anything man made will break down.

i understand your pain and i get you are upset, but 3 or 4 people on the internet with this issue and there are thousands of these cars out in the wild, that is not a call for a class action lawsuit... and ooh, who wins in class action suits?? the lawyers! Certainly not the people behind the suit.

doesn't matter if the car is 100000000 dollars or 10 dollars, it can break.

perhaps you should take this up directly with nissan corporate and vent your case there.
 
Unfortunately I have vented my case to Infiniti/Nissan and received little help at all. According to my dealer and other posts on this site the timing chain issue is a very real issue that is prevalent and not isolated to "Lemon" vehicles. In fact, I talked to a random guy from another state last month at a gas station that had the same exact problem with his QX at 72,000 miles and received no help from Infiniti. My frustration stems from a perceived lack of caring on the part of the manufacturer in this case. We are not talking about repairs that are a few hundred dollars. These are repairs that are a few thousand dollars. My intent is to get any feedback from other consumers that have had the same issues, and hopefully we can better understand (a) the problem and (b) how we solve it.
 
hi,

i understand what you are saying, but jumping online and trying to ramp up anger and class action suits will not help you "understand the problem" and "how we solve it".

They say (who is they? :D) you can get more files with honey than vinegar, so take that approach.

again, one "random" guy out of thousands of qx owners is not a major fail. im also not saying your issue is not real--i know it is very well real--but to say its just a huge problem period is just overkill.

again, i stand by my initial statement; there will be some cars that come off the line with some issues. it happens and you were unfortunate to have had this issue.

i know its an uphill battle trying to fight the big corporate giant, and i wish you success in your personal issue with the car.

Having read through all of these posts, I'm left wondering what happened to Service Warranties, Extended Service Warranties in all this? I realize that it's possible the warranties may have expired, but isn't true one can re-purchase another one prior to expiration.
 
yup... just buy the extended warranty.. wait the one month "wait period" and then file a claim.. play their game.
 
2012 QX56 timing chain

I have a 2012 QX56 with 60K miles. It has been at the dealer since July 23rd. Service rep told me the timing chain needs to be replaced. It had the same problems discussed here like the sound after starting the engine first thing in the morning and lurching or bucking forward but never getting over 10 mph. Fortunately for me, I was two miles from home and was able to limp back to my garage. Service at my dealership in NJ has been great! I told them I need my car back by Friday, August 8 for a road trip to Maryland. They called their tech in from vacation to work on it this past Saturday.

Back in March, my QX was at the dealership and my invoice says "test timing control system replaced faulty bank 2 cam timing actuator." The part they replaced was a valve assy solenoid. Is this related to the timing chain issue I'm having now?

Will this timing chain repair be the end of this problem or should I expect more problems? Will my QX be safe to use on the NJ Turnpike? I would sure hate to break down with my family in the car. Any help or comments are appreciated. This is my second QX and I love it. I have my eye on the QX80 in the near future.
 
Timing Chain

Has the timing chain issue changed from 'unlikely' to a status of 'when' is it going to happen?

Has Infiniti issued a TSB on it ? I think the only recall I have seen is something to do with the gas gauge.
Some of you have not had this happen correct ?

Marc, your engine is still fine right?
KCrebel, you haven't had any timing chain issue?

I haven't either and was just wondering if were still in the majority ?
Thanks

I haven't had any issue with my timing chain either .. 2011 QX56 but I don't drive much with only roughly 26,000 miles on the odometer.

I would be interested to know what the oil change intervals were on those who did experience a timing chain failure. I heard from our service manager the jets, which spray the timing chain, have tiny openings in which the oil sprays through. If the oil in the engine is mildly dirty it could impede the flow causing timing chain failure due to lack of lubrication. I personally change my oil before the 3,750 mile mark as recommended by my dealership.

I think the only recall I have seen is something to do with the gas gauge.

I haven't heard about the gas gauge TSB .. any insight as to what the remedy is?

So would I. My dealer told me not to worry about mine that if it ever happened my vehicle would be fully protected bc I have had the oil changed by the time on the recommended intervals each time since new.
He said they have had one at their dealership fwiw and it was one that wasn't maintained as recommended. Something like 12-15k per oil change. Engine failed at or just before the "third" service on that cycle.
Certainly not an indictment towards anyone else on this thread or elsewhere either. Just sharing what I was told and made me wonder the same things....:confused:
 
fingers crossed

Thanks Grillmaster, Yeah I am a low mileage too, 2011 w 14575.
The oil change interval could be good indicator. I have been trying the 3k to 3500 mile oil change interval. I have been exact on the miles on the oil changes documented, with every receipt for oil and filters. Engine sounds good, have been using the Mobile One and Mobile One oil filters. They are made in USA, where as Nissan filters are made in china these days, not even Japan !

If KCrebel has to have his engine fixed, then we'll know something is up. I don't use mine for short trips like grocery store. I am trying to make sure it gets thoroughly warmed up and run for a while.

I don't think Marc has had this issue either. anyone else havn't had it ?
Best regards
Parrott
