| My '97 Q cuts off in a hard rain. Not all the way; just for a fraction of a second, repeatedly, lurching like a bucking bronco. Feels like you're hitting airpockets in a plane. It's got to be hard on the drive train and engine. The dealer says he's got to catch it while it's doing it to hook up a machine and tell what's going on. I don't live close to him, so it's next to impossible to do this. Anyone have a clue? | |
| I had a similiar problem with my LS400. Brought it to the dealer several times. First couple of times they couldn't figure it out - frustrating, espeically since mine did cutoff in the middle of a busy intersection with wife and newborn in the car. Anyway, during my 60,000 mile service they played with some ignition wires (car was previosuyl in an accident). They went back and looked over the wires and "retaped" them. I am not an mechanic type so I can't give you more details than that. Nonetheless, haven't had the cutoff problem since. | |
My 94 Q45 has been flawless since I've had it nearly 1 year. However, the trip odometer display screen has gone blank. It doesn't indicate "OK" when first started, no diagnostic warnings, no trip mile information, no nothing - it just went dead. Looked at fuses but didn't see any one fuse dedicated to this function. Any ideas??? msrankin prodigy.net

In the past many brands of cars had seat-track-extenders. Maybe you can get them for the Q45. You cannot expect perfection in a car with rear drive and only 45% of its weight on its drive wheels. The first time you are on snow or ice you will hate yourself for choosing this model. Other unrelated posts on Edmunds note short life of front brake rotors and oil leaks from the differential, as well as ignition cutoffs in rain. |

Hi all, I have a 95 Q soon due for its 60,000 miles service which, I understand, is going to be quite costly. Does anyone have any insight as to how much bargaining is possible, and what I should consider a good price? Thanks. |

The first thing I'd do is get a list of what will be done to your car at the 60K. See if there are things you can do yourself. Next, you may want to shop around for the service. I don't think there is a law requiring you to do this at the dealer  Some shops who specialize in Infiniti or Nissan will have their own 60K Service Idea. Check them out.Alot of people will say it's a waste of money. My thoughts are that the Q45 is a great car but expensive to maintain. By trying to save a few bucks, all that will happen is that you'll get burned with expensive repairs in the end. I'm sure you won't see it as a waste. |

| Some scary stories here! We have a 94 q45 we bought used at 32K,now has 65K and 3 years,not one single problem with it,I don't consider brakes,etc to be problems,but maint.items. I did the 60k service myself for around a 100 bucks,biggest pain is the spark plugs,took 5 hours to install,but only cost 20 or less,air filter was 15,changed the brake fluid,tranny fluid,anti freeze,I did the brakes also,new front rotors were 75 each. only gets 18 or so on the highway with the wife driving,when I drive it it gets about 13,but its a blast to drive | |

This is an update to my previous message #72 above. I took my Q back and they replaced the tires with Michelin pilots. There no longer is any shimmy. I have also found out about the jerk of a down shift and the pulsating feeling I encounter at 50-60mph. They say it is the torque converter. I am wondering if I am the only one experiencing this problem. The symptoms are: Just over 40mph I feel the car shift into overdrive. If I take my foot off the gas, the car jerks. The other is that at 50-60mph if I just cruise, neither accelerating nor decelerating, the transmission and car itself seem to pulsate, not always, but enough to bother me. IS anyone else experiencing this? As for the heat in the driver's side, I have not noticed it. However, I am in Florida and seldom have the AC turned off. |

I have noticed a lot of posters take their cars to dealers for servicing. This is one reason maintaining these cars tend to be costly. This is true of all car makes and particularly so for luxury marques like Lexus and Infiniti. I recently needed the 60K for my Lexus ES300, for which the local Toyota dealer quoted me $1400. He tried to sell me on the point that the Lexus dealer would charge me about $2000 for the same service. When I bought the car, the previous owner also cautioned me on expensive services, him also using dealership servicing. I finally found a Toyota/Nissan expert to service the car for me, for the total cost of $580, which also included a brake service and a front end alignment, which would have been extras at the dealerships also. |

I had a 1990 q-45 and loved it. Dealer was very helpful and found a way to cover problems with warranty ect. When it was time to get a new car I bought and 1994 kia or at least that's what my new q has brought me. It had about 75K and I decided, for the $ I could not get a better car so I would put a little $ in it and drive it for a few more years. I did some work ($800) to the front end that I had been putting off and had some other nagging problems fixed. I told them when I took it in to check to see what was causing it to spit and sputter on occasion. They told me everything was ok, and that maybe I had bought some bad gas. Anyway after I got it back the spitting and sputtering continued and I took it back. They then determined that the injectors were leaking and had to be replaced ($2K+). Well I was already $800 into it and said go ahead. When I got it back about a week later, I noticed a burning oil smell. I took it back thinking it must be something with the injectors--but no, it was the head gasket on both sides. They swore they did not touch these during the injector repair> Another $800 later I'm ready to get out of the car for almost anything. The Infinity dealer changed hands and that could be part of the problem, but I just don't get the good feeling I had with my first Q |
