NHTSA Complaint #11526603 — 2015 NISSAN ALTIMA

My 2015 Nissan Altima started having some steering issues over the 2022-2023 winter. It seemed a bit stiff, but I thought it was from the snow tires I had just had placed. When it continued after change over in the spring to regular tires, I took it in and they said I had low power steering fluid. They replaced it for around $100 and it was working fine. they said there was no leak in the steering fluid, however. Since they replaced the steering fluid, (over the last month), the steering intermittently will completely go out for a few seconds the car will start pulling to the side, and I will have to crank on the wheel, and then it self resolves. I took it into Boucher Nissan in Waukesha, Wisconsin. They went over it for about an hour and they said they couldn’t find any problems. This is happened two times again over the last couple of weeks. It is also starting to sound like the engine is almost going to give out at times. I don’t know what to do because if it’s intermittent, how are they going to fix it? I could take it to another mechanic, but he may not find it either. I’m a bit scared to drive and driving slowly.
