The contact owns a 1999 Nissan Maxima. The contact stated that while driving at 25 mph, the vehicle stalled without warning. The vehicle was able to restart. The failure occurred on several occasions. The vehicle was taken to the independent mechanic for diagnostic testing, who stated the ignition switch needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was unknown.

I have 1999 Nissan Maxima and it started giving problem with the ignition coil when it had only 50000 miles and the mechanics were not able to find which coil was having the problem, and finally asked me to change all the six coils for around $1000. They also told me this is seen in many Maxima's and infinity I30.

I have a potentially deadly problem with my 133,000-mile, 1999 Nissan Maxima. It might be related to the crank sensor on newer Maxima, a steering column lock, a faulty ignition switch, faulty clutch depression switch, and the anti-theft kill switch, perhaps even a random ground. The problem was conceivably catastrophic. Upon entering my car using the remote, occasionally the car won't respond, and must be unlocked manually. In these instances, neither the dome lights nor the headlights shine. When the ignition key is rotated to the start position, as the clutch is being depressed, sometimes the gauge lights appear and then quickly fade and disappear; the car just doesn't crank. A faint, diminishing telltale buzzing sound can be heard. What's worse, this can happen spontaneously while driving, in which case the car's steering wheel locks and the brakes become inoperable. I have had this happen on three occasions, twice while driving in a mall parking lot (February and March ''07) and the other time (just last week) while turning into my neighbor's driveway, to take out her oak tree. The ignition crank sensor must slip into an inoperable mode during driving or while attempting to start the car, or the anti-theft switch somehow interferes with starting, operation or driving. Maybe the master ignition coil is failing (but that doesn't explain the headlight and dome light problems). The clutch switch may not engage when its pedal is being depressed. Sometimes, I can restart the car after an incident in which it was parked for a while. My battery is brand new, and there don't seem to be any shorts as far as I can tell. But nothing electrically works (not even the radio) when I have to unlock the car manually. I am very concerned about driving the car beyond my neighborhood. I might have to become a hermit, or worse, a college professor. Any ideas? the car is in excellent shape otherwise and has all service records.

This comment is regarding the ignition coil problem on the 1999 Nissan Maxima. My 1999 Maxima has about 71,000 miles on it. Recently the "check engine soon" light came on. We took it to a Nissan dealership service department. They ran a diagnostic test ($93) and said it's giving multiple misfire readings. They recommended replacing all six ignition coils. Total cost about $1000 including the parts and the labor. From websites, I found that this same problem happened on several Maximas. People complain this a lot.

: the contact stated the check engine light illuminated intermittently. The vehicle was taken to the local dealership when the light illuminated. The dealership was not able to duplicate the problem; however, they did reset the check engine light. The vehicle was inspected by the dealer, and they suggested changing the ignition switch.

Consumer cannot start vehicle with key, the key will not turn ignition switch, consumer stated this was original key received with vehicle. Consumer contacted dealer, and dealer had to recode key.

Ignition system immobilized when using proper coded Nissan keys. Keys recoded, problem still occurs later. Nissan/factory rep knows max SE have aproblem, but don't know why. I have a car that I never know when it won't start and must be towed in!!

Ignition switch intermittently works. Dealer has had vehicle in dealer's shop for repairs 5 times. Consumer is filling for lemon law.
