I notice when I brought this car at 47,000 miles used the car was lack of power and hesitated to go when trying to pass other car ..I thought it was just software problems but it happened the 2nd time , but this time almost cost the accident,when I was going to make a left turn the hesitated for about 6to9second delay befor it take off was close of other car hitting me
The car won't accelerate when pressing the gas and also will jerk and jump when shifting. It's very dangerous when driving on the expressway because the car won't accelerate, but sometimes will take off on it's own even when I press the brake. This is definitely a transmission problem which I've heard before on several occasions about this particular car. Also, 2 lights stay on on my dash when these things are happening.
I purchased my car used with aprox 45,000. Miles on the odometer, I test drove it & it ran & handled perfect. As soon as I took the car home I brought it to my mechanic to check it out, I got the oil & filters changed & car inspection, all was good. I owned the car for 3 years & maintained it regularly. One morning I started it up & it started popping & jumping (the day before it had run perfectly) & my check engine light was flashing. At this time there was approx 65,000. Miles on the odometer, there was less than...

1000 miles since my last oil change. I took it to my mechanic & they told me there was no oil in it..The oil was completely gone. There was no oil spots in my driveway at all we couldn't understand where the oil could have gone in less than 1000 miles since my last oil change. The mechanics filled it with oil, I drove it only locally a few weeks & when I checked it again the oil was gone..With no oil stains in my driveway. I called infinity, they towed it to infinity dealership in nj, the dealership told me it was due to neglecting to have the oil changed & I needed a new motor which cost approx $12,000. I told them I have receipts of the oil changes & they said then it was neglected prior to my owning it which I cannot understand how that could be after owning the car for over 3 years without a problem, they then accused me of neglecting the car because I didn't bring it to them for maintenance. No one I spoke to can understand how it could run completely out of oil in less than 1000 miles & it didn't start running bad gradually it literally happened overnight. One mechanics I spoke to said it may be a defect to look up recalls, I saw a similar issue on some model infinities but my car was not included in the recall. I now have less than 69,000. Miles on an infinity which needs a new motor that costs more than the car value.
2 Days ago I was leaving the market & my car won't start every light from engine , brakes, electrical come on. I waited 15 minutes @ it started. This has happened at least 7 times. I have may serviced on a regular basis. I've mentioned it to my dealer, I thought it could be my battery, it was not. The said they don't know what is going on. I've had to call family to come & get several times. The car was stationary each time.
Vehicle won't start replaced battery 2 within 4 months infinity dealership can't find out what the problem is but car won't start . Can charge battery drive small distance and car will not start had two places check alternator and starter stated no problem but unable to find the drain
Traveling on i95, minimally slippery conditions (snow), car suddenly starts hesitating/jerking. Unable to accelerate past 44-45 mph, 2400 rpm. Had to move from the far left lane across 4 lanes shoulder. Apparently vehicle entered "failsafe" mode. Took to dealer later in the day, at which point the vehicle worked normally. Dealer (jba infiniti) said "carbon buildup." No other defects found. Charged approximately $325. One or two weeks later, the same thing happened. Problem obviously computer issue. This is dangerous, similar to gm incidents when problem occurs on high-speed roadway without warning. *Tr
While driving the car would not accelerate and the transmission was hesitating severely when pushing on the accelerator. Problem continued until the car had no power and the engine shutdown without any dashboard gauge warnings in the middle of traffic, during rush hour. I placed it in neutral prior to complete shutdown. Cut off ignition and restarted ignition and car started as normal. Tried to drive but after five minutes began to shut down again. Per the dealer defect has something to do with the fuel injection sensors. This could have been a catastrophic event. *Tr
2011 Infiniti m37. Consumer writes in regards to air bag malfunction and engine not starting. *Smd the consumer stated the air bags did not deploy during an accident, in which the repair bill was in excess of $20,000. The consumer also stated the brakes were a constant problem.
Have owned the car slightly over a year. Since the beginning the transmission has shifted erratically, is in 4th gear at 25 mph. When stepping on gas the car hesitates while trying to pick a gear. There is no power at low speeds because the car is in too high a gear. At higher speeds if you touch the brakes the car drops two or three gears causing the car to shake violently from the downshift. The engine knocks constantly at low speeds due to the gearing even though premium fuel is required. Dealer has tried...

to repair and applied software patch that took almost a year to receive but no help. Dealership says nothing can be done. From research and other nhtsa complaints this is a common problem. Tried to get infiniti to repurchase but they refuse to stand behind car, say it's "within specs". Car is unsafe because of severe downshift compression at higher speed, no power and severe hesitation at lower speeds. *Tr
9/25/2012-I am having some severe issues with the brakes on the m37. Yesterday I just avoided an accident with the back end of a ups truck as the car would not stop. This is the third time that something like this has happened with the brakes. Each time it has been while traveling above 50 mph and trying to stop quickly. The reaction of the car is similar to that of an anti-lock brake system when you are on wet or icy roads. However, the roads have been perfectly dry and the sun is shining. When trying to use the...

brake to decelerate the pedal will pulsate and the engine rpm will increase significantly. Basically the car drives through the driver's command to stop. Last night it was so bad that I had to swerve into the oncoming lane because it would not stop in time to prevent me from rear-ending the ups truck. I am a very sound driver that does not tail gate and this car has done this now 3 times. The other two times I was trying to avoid animals that shot out in front of me. I see that this has been a known problem on several model year cars for infiniti. *Tr
I leased my infiniti m37 sport the first month it came out in 2010 (2011 model). The first day I drove the car the issues were apparent. I drove it directly back to the dealership, they said everything was fine..Its learning your driving style..(I too have had mercedes, bmw, audi etc that learn your driving style) this was not the case. Well, now I am at 33,000 miles and the issues have only gotten worse. Its been to the dealer a number of times for the jumpy stops...When breaking (normal non aggressive) the...

tranny wants to jump forward and almost hit the person in front of me. Its extremely scary and infiniti has nothing to say about this? It not only does that but when breaking it downshifts bad and bumps at times. With the ac on I noticed it does all of this more frequently, although the issues are always there. Now it randomly drops rpm's almost down to stalling then kicks it back up (catches it self - large rpm swings) while at a complete stop. I've done the ecu flashes and other tricks that have done absolutely nothing. Sad thing is this car has one of the best designs and most amazing interiors, just one of the worst engine set ups ever...Very dangerous and there has been a number of times my car almost jumped forward while braking and hit the person in front of me. I am really upset, can someone please look into this, there are a ton of complaints online and no one is being held accountable for a fix. Please see this link to see some of the issues, I thought I was the only one, but that's not the case. Please help! *Tr
