Business ProfileforRound Rock Nissan

In February of 2024, I purchased a 24 Nissan Sentra. The car's computer is not functioning properly. While driving, the screen will shut off and remain off for minutes at a time. No map, no music, nothing. This is a safety concern because it forces me to look at my phone for directions while the screen is bricked. Bluetooth and Carplay both cause this issue.The dealership is aware of this. I have taken the car in five times now concerning this problem, but they have yet to fix it. Employees at the dealership have not been transparent about their ability to fix it. The first time I brought the car in, **** (service center employee) stated that the issue was with a recall (24V-304) of the drive shaft. When it continued to not work after that, I brought it back and **** said that the recall was actually never the issue, stating that a software update would fix the error. Of course, it didn't.I brought the car in AGAIN, and ****** (general manager) stated that he would open a case with Nissan to have the radio system replaced. I left the car with ****** from Friday morning to Saturday afternoon. When I got it back, instead of opening a case, they had replaced one USB ***** They told me to "change the cord and try again." Now that they've replaced the ***** CarPlay doesn't work at all.When I called ****** to tell him, he said that he would need to see the car AGAIN to file a claim with Nissan. I reminded him that he'd just had the vehicle for over 24 hours and had not done so then as he'd promised. I'll still bring it in, but it's unfair that I've been paying for ubers from/to Nissan when they aren't actually fixing anything.I want the vehicle functioning as it was advertised to. I want to be given a rental car while they work on it continuously instead of giving it back to me and crossing their fingers. If that's impossible, I want financial compensation.I need my car. I can't keep leaving it with them w/o a rental. I'm a full-time worker and graduate student.
