I had my car towed up to Clay Cooley Nissan of Dallas on LBJ because it wouldn't start. Got in it one Friday morning to go to work. Pushed the botton to start it , dash lit up but car would not start. After pushing the button several times, I couldn't get the car to turn off (dash would not go off) . I had to be at work so took another car and left my Maxima with dash lit up or I guess you can call it "on" but not running mode. Needless to say when I got home 8-9 hours later car is off and battery drained. Car is towed to Nissan Saturday morning. Monday morning Service Advisor calls and says the battery is down! I'm like are you kidding me! I told you on Saturday the reason for the battery being down. That is not the cause of the initial problem. Advisor proceeds to tell me that they can't tell me what's wrong with the car because they can't get it started! I swear to you I'm not lying. You mean to tell me that Nissan doesn't have a battery they can put on my car to aide in diagnostics? You " Nissan" a multi billion dollar corporation doesn't have a battery? Are you not a car dealership?? I tell the advisor" sir I just purchased a new battery 8-9 months ago.. Have you tried to charge the battery?" Do you not have a battery you can put on the car? That way we know for sure it is the battery ( maybe bad cell or something- I'm grasping at straws here). The advisor says " We don't have test batteries here. The best I can do is take your battery off your car. You come pick it up, take it back to NTB have them give you new battery. We can then diagnose your car". "Oh and by the way, I'll have to charge you a $20 labor charge for battery removal". Ok, you are charging me $135 for initial diagnostics, now add $20, because you can't diagnose it because it won't start because it potentially needs a battery? What's the $135 for.? My thought is you puta battery on the car, you say, " Hey we diagnosed your car, it was the battery, it's $135 , if you would like to purchase a battery from us it's another ..uh $125 so, total cost to repAir car is $260 . Or bring us $135 and take the battery you have back to NTB". I had to go up there, get my battery take it to NTB get a loaner battery, take it back to Nissan.. Awaiting diagnostics.i will never ever use Clay Cooley Nissan of Dallas again.
