Q: I have a 2012 Infiniti QX56 and went through exactly what this person did with the truck going to the dealer in perfect order and

asked by on

I was shocked to read that I had the same exact problem for the same exact vehicle as another person who had a question. My truck went in working fine came out with no A/C after the recall work was done. The dealership told me that I had a leak in the AC but didn't say it had failed. I said I would do it later they said okay. Then I had to drive 1300 miles to Florida and I didn't have any AC at all and it got super hot and I suffered including getting caught and heavy downpours with no defrost! What can be done about this obvious rip-off?

My car has 54000 miles.
My car has an automatic transmission.

A/C systems that are leaking will function up to a "threshold", that is a minimum level of refrigerant charge, but once the charge drops below that threshold the system’s low pressure cut off switch will shut down the compressor. The low pressure switch is there to protect the compressor because the compressor oil circulates with the refrigerant and if there is too little refrigerant, there is too little circulating oil. In your circumstance, the ONLY way to determine conclusively if the shop broke something is to know the state of charge (amount of refrigerant) before you gave them the car, the leak rate, and whether or not the subsequent failure was due to a sudden enlargement of the leak (e.g., a pin hole blowout in a condenser which will empty the system in seconds) and when the enlargement occurred (e.g., shop accident or on the road?). The problem is the missing data make any determination impossible. One oddity in your case though, as you put the pieces of this puzzle together, is the fact that the recall involved a possible defect in the fuel pressure sensor. Work on that sensor does not implicate the air conditioning system at all and so in composing my response to you, I am puzzled as to why they ended up diagnosing a system on your vehicle, the A/C system, when that system had absolutely nothing to do with the specific recall and perhaps you did not even authorize that a/c diagnostic?
