is it normal for the car to bog down a little every now and then at a stop light when the A/C is on? I have an 09 with 71,000 miles. the dealership 3 month warranty is over in 500 miles. Needing to know in case I need to take it to them! thank you!!

 

Not sure what you mean? Do you mean the rpm's drop a bit while sitting at the stoplight? How often does this happen? Every time you stop? Could it be the ac compressor turning on?
Give us a bit more details and I am sure someone will be able to point you on the right direction. Personally, I'd say a little rpm drop when the compressor kicks on is normal but if you have a warranty which won't cost you anything I say take it to the dealership.

 

It's only every once in a while at a stop light and drops from 700 rpm to about 550-600 and shakes the car for less than a second and then back to normal. It doesn't do it every time I stop. It probably is the compressor but doesn't seem like it should make the car shake for half a second. My old Corolla would do that but that's a huge difference in car.

 

It's from the compressor cycling on. Our Murano does it a little bit more than the Maxima. Kind of cheap feeling for sure. The 2.5L Altima I drove 83k miles never did it, though. I do wish they would idle a little higher, maybe around 800-850 rpm would smooth it out.

 

Drive around for a couple of days without A/C on and see if the hesitation goes away. If it doesn't then the problem is elsewhere.

 

It doesn't do anything weird or odd when the AC is off. so it is only when there is a load on it.

 

Then it's safe to say it's the ac compressor turning on.
