I have 2008 Nissan Altima 2.5 S which has push button start. I.e. person has to push button and press brake at same time to start the engine. There is a switch / sensor near brake pedal which sends signal that brake has been pressed (and also turns on rear brake lights). One day, all of sudden, when I tried to start car it didn't start. It keep saying press brake (accessories / radio etc all turn on). So the cycle of accessories - on- off kept on happening. I thought battery is weak and even tried jump start. So, after trying pushing brake + button for 30minutes, car finally started. This happened 2-3 times and I got very frustrated....finally I started reading online about this problem. Many people have posted same complain / issue. They suggested to check whether rear brake lights turn on when I press brake or not.. if not then the switch is bad.. I saw many people were able to fix problem by replacing switch ($50 expense). I did the same and car has been working fine since then (2-3 months). Dealer tries to charge $150 only for switch and then $500 for other stuff to eliminate root cause of issue.. as many people are effected by this issue, I firmly believe that Nissan should recall and fix this issue at their cost. Dealers are making tons of money off 2007-2008 Altima owners.

Vehicle was driving along with other normal traffic when it suddenly lost power and stalled on an incline. Driver carefully steered vehicle to a safe place downhill and called a towing company to tow vehicle to driver's residence. Upon visual inspection of engine compartment, a rubber seal on the ECM wiring harness was found buckled up. On trying to remove and re-insert the harness, it was found that ECM terminals had corroded and some pin contact had actually fallen off. Upon doing some research, this was found to be an issue covered under federal emissions warranty. Driver/owner called the local Nissan dealership who immediately, presumably at their own expense, towed the car to their facility, checked and found the ECM to be faulty but blamed the faulty wiring harness for the failure. And further, the dealer claimed since the harness carries a 3 year warranty and was the "cause" of the ECM failure, this was no longer covered under federal emissions warranty resulting in a bill of $2,000+ for replacing the faulty - corroded - wiring harness and the faulty ECM. Attempts to have the dealer do more research or contact Nissan usa for advise fell on deaf ears. If the car had stalled on high speed and caused fatalities on the highway, would these repairs then have been "part" of federal emissions warranty coverage for publicity purposes? it is out of sheer luck that 1. the car stalled while going downhill and, 2. the car was traveling at 40 miles per hour. I desperately need advise on this while I await for delivery of a special order for the ECM and harness. In the meantime, my rental car expenses are piling up and are not covered by any warranty.

I have 2008 Nissan Altima with a manual transmission. About three weeks ago I noticed that the vehicle has been "dragging" in first and second gear. I have not noticed any problem with the clutch. The gears shift as normal but there is a squeaking noise. Even in 3-6 gears the vehicle will not pick up speed as it should. I took it to the dealership and they tell me it is the clutch that is worn out. There is no check engine light or any warning sign showing. Normally a clutch burns out and the pedal will fall flat to the floor. In this case none of that has happened. I bought the vehicle from the dealership in 2009 with 11000 miles on. I have been driving a jetta with manual transmission since January 2005 with no such problems. My research on internet indicate other people have similar problem with Nissan manual transmissions.

Car has developed a terrible wobble or shimmy between 30 and 40 mph. Nissan maintains it is in the cvt transmission. I have had the car into dealer many, many times.. no solution. But, all agree the car wobbles and shimmies at 30-40 mph. I have had Nissan engineers drive car, same result;.nothing. I have written to Nissan corporate offices, no solution. Told by Nissan that my driving style may be too conservative for car. Told by Nissan execs to drive car harder and faster and avoid speeds between 30 and 40 mph. How absurd. Nissan says there is no solution, so live with it. This car is a danger. What will happen on snow and ice. The consumer stated the transmission was reprogrammed several times, but to no avail.

My Nissan shakes and flutters when I take off., I think that there is a major defect in these new transmissions. The Nissan dealership assured me that this was a normal operation. I've been around long enough to know that a car shouldnt hesitate from 20-55 mph.

Purchased a 2008 Nissan Altima, drove the car for 3,000 miles. Cvt transmission started making strange noises. Turned out to be defective. They replaced it, but did not put it back together properly. Been having problems with it ever since. Nov 30, 2009 took vehicle in for scheduled maintenance, had them examine transmission again for a grinding noise. They did not "see" anything wrong with it but acknowledged transmission could be defective. Car is going in for more "tests". Nissan extended the warranty to 10 years 120,000 miles for cvt's, however I don't feel safe driving the vehicle.

Brakes were making a noise for a 2nd time; already replaced once when I told abc Nissan phoenix, AZ (where purchased) that at speed less then 25 mph my brakes were making a noise. The other day went to brake at 14 mph in very heavy traffic on the freeway during rush hour and brakes locked up and had to use the emergency brake to avoid a collision (mind you I was one car length behind the car in front of me). I am afraid to drive my Nissan Altima now!! this is ridiculous.
