I love this vehicle but it's suddenly started having a rough idle and with a scan tool detects multiple misfires and several codes due to timing, in which case the timing chain has been worn out call the dealership to see if the timing chain recall for the m56 was done to my car they said it was VIN specific now I am stuck with a vehicle that is very dangerous to be driven.

Check engine light has been on for 2 years. I've repaired just about everything possible that comes up on the code reader and nothing keeps the engine light off. I've gone to the dealer for repairs and they cannot every guarantee their work will fix the problem. Another mechanic has repaired air flow sensors, etc. And he keeps telling me it's a computer update that's needed to fix the light - not the problem with my car.
Vehicle stalls while driving sometimes at 3/4 full and sometimes at 1/2 tank full of gas and sometimes in between the two making it unpredictable and unsafe.
I started the car up and started to drive to work about 3 miles into driving the check engine light came on followed by revs with no power or speed gain and the vehicle was giving me around 15mph to the point where I couldn't gain much more speed and had to pull off the road. There was a voluntary service campaign for the timing chain but it has since expired and now I am stuck with the repairs.
The engine repeatedly stalls driving at low speeds or while braking. This has happened dozens of times, including while driving through parking lots, braking during rush hour traffic on city streets and freeway off ramps as well as braking on a left turn through a traffic light on a highway, almost causing me to get rear ended multiple times. This problem is identical to problems that precipitated a recall of other inifiniti models, same model year, however the ex35 was not included in the recall. Car has been taken to the dealer who cannot identify the problem.
Auto stalls at low speed motion either while slowing down or starting to move. Stalls out in traffic and almost caused several wrecks on a city street when stalled trying to get through traffic.
While driving, and I'm getting ready to slow down or stop. The car completely shuts off. I have to put it back in neutral quickly in order for it to start. Also while at a complete stop. Once I accelerate, the car just cuts of in the middle of the road! This week alone I've almost had three accidents because of this. My car has been at numerous repair shops. They've all stated the cannot find anything wrong. Once my check engine light comes on. Bring it back. Really?! It cuts off daily, while in motion at least 6-10 times. *Tr
Tl* the contact owns a 2008 infiniti ex35. While the vehicle was parked, after being driven approximately 45 minutes earlier the contact noticed a burning odor in the cabin. A cloud of smoke also appeared. The contact took the vehicle to two mechanics and the dealer where it was diagnosed that the wiring harness and body control module needed to be replaced. The vehicle was repaired. The manufacturer stated that due to no recall and warranty expiration, they were unable to provide a repair. The vin was unknown. The approximate failure mileage was 167,214. Updated 04/19/17 *lj updated 7/6/18*jb *tr
Driving this car is very fun and I have enjoyed the car very much but just last week I noticed a smell like burning rubber or oil, come to find out the next day I was dripping oil only not a steady drip but a drip only from driving, once I stop and the car cools the drip stops. I have research and found that there could be a problem with some bolts to the oil filter that attaches to the block but when I called infiniti they don't see it nor will they look at the car unless I pay. This isn't a seal or gasket this is a very bad leak, my research came from a 2012 long term road test on a 2011 infiniti m56 and states this will become a recall but never did? *Tr
Tl* the contact owns a 2008 infiniti ex35. While driving at various speeds, the engine stalled and the entire instrument panel illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 65,000.
My solenoid switch went bad on me and needed to be replaced, took it to the infiniti dealership and they corrected the problem so I thought until oct 13 when I kept hearing this noise coming from my hook like a squealing noise.. Took it back to the dealership and found out it was the timing chain, which I was told had nothing to do with the solenoid switch that was previously fixed.. Found out that was a lie and that they go hand in hand with each other and they wanted to charge me 1400 dollars just to look at the...

problem and another 2,000 to fix the issue, well it turns out that infiniti already knew that this was a problem with the solenoid being to small to pump the required old to where its suppose to go and never did a recall or anything but they are trying to say if its out of warranty than they are not required to fix it, this is a safety hazard if not replaced by infiniti this will cause the solenoid switch to go bad then the timing chain, and then your engine will blow up on you.. This should be a recall issue for infiniti to fix because this will be very costly to someone and it shouldn't be... *Tr
Tl* the contact owns a 2012 infiniti ex35. The contact stated that when the gear was in drive or reverse, the vehicle stalled as the push button starter switch was engaged. The vehicle was taken to an authorized dealer, who stated that the vehicle operating as designed. The manufacturer was not notified of the failure. The approximate failure mileage was 5,000.
This car had an unexplained episode of sudden engine power loss and deceleration followed by engine shutdown and temporary inability to restart the engine. While traveling at approximately 60 mph on a slightly inclined highway, I suddenly felt that the car needed to downshift but it was not doing so. As I continued to exert additional pressure on the accelerator, the car began to noticeably and quickly lose engine power. The power steering and power brakes worked normally, and I was able to pull off the road, by...

which time the engine had stopped running. I estimate I traveled approximately one half mile from the first sign of trouble. There were no unusual sounds or odors. If any warning lights came on, I did not notice them. Accessory items such as the radio, air conditioning, navigation system, and power windows still operated. I tried several times unsuccessfully to restart the car. The engine did not turn over. I did not notice any unusual lights or messages on the dashboard, but the brake pedal did not depress as it normally does during the starting process. The tow truck driver who arrived a little more than an hour later started the car normally. There was no hesitation in starting, and the engine ran smoothly. The incident occurred about 10 to 15 minutes after I started the car for the first time that day. It had been driven less than 5 miles in the previous 5 days, but otherwise there was nothing unusual about the driving conditions. Since this incident, the car has been driven about 700 miles on the highway and been used for several days of local short trips without any problem. It has been checked at a general purpose auto repair facility and then by an infiniti dealer. Nobody has found anything to indicate what the problem was. *Js
Radiator cracked at the junction of the aluminum and plastic causing the car to overheat and stall. It was explained to me that this was not uncommon due to the use of plastics in the cooling system now. There is no repair able to be done because of the plastic and the radiator needs to be replaced. *Tr
The brakes squeak constantly with dealer parts. My radiator cracked and needed replacement at about 50,000 miles. According to several owners on the nico blog this is a common problem. I am very concerned about these issues. I would like to know what can be done. *Tr
