Midway Nissan Did not honor warranty. Tech and salesman did not properly diagnose issue. Phoenix AZ

I purchased a new 2017 Nissan NV2500 from fleet with a 100k bumper to bumper warranty. Paid extra for Midway Nissan to install trailer hitch and backup camera. The dealer sent the van to Commercial Van Interiors for this. Trailer brake lights never worked and at 30k miles check engine light came on for an Oxygen Sensor.

Made specific appt. with Midway Nissan to repair these two items. After 7 hours Nissans "Master Tech" was stumped on the trailer light issue and simply cleared the code without fixing replacing the oxygen sensor. They blamed the trailer light on whomever installed the backup camera (CVI).

Furious I spoke to the sales manager about her incompetent tech and lying service manager. I told her the root problem has not been solved and the check engine light will return after 100 miles and the computer resets. She was denying and defensive, I ended up getting irate and calling her a stupid bi**tch.

Meanwhile after 100 miles the check engine light came back on. I called Gionni, the lying service manager and told him this. He said he would need to get his shop manager involved and to bring it back anytime. I took it first to Commercial Van Interiors. Within 10 minutes they found and fixed the problem, they said nissan spliced into the wrong wire and it had nothing to do with the backup camera. They also found that Nissan did not plug in 2 wire harnesses while diagnosing the trailer light problem. This van was being driven for a week with no brake lights.

Took back to Gianni at Midway Nissan and told him all the problems and his tech was an idiot. The sales director (missing her 2 front teeth) told me to get the van off their property or she would call the cops since I called her a stupid b**tch.
