While heading west on interstate after a Drs. Appointment my wife was driving our 2021 Nissan Altima when suddenly there was a loss of power to the engine as if the engine was overheating or had loss of fuel or only able to slowly exit the freeway to a safe place and call a tow truck, after 1 1/2 days of diagnosing and testing. I was able to drive the vehicle with no issues for approximately 4000 miles when the exact problem has occurred this past Friday 6-19-2026

This has been an ongoing issue for over 2 years where I go somewhere, park and come back out and my car won’t start. I literally have to have someone come in to give me a jump so the whole time I was thinking it was a bad battery so I went and bought a new battery. Well fast forward not even 7 months later I’m in the same position I go to the store come out and my car completely has no power so I take the car to autozone and what do you know a faulty engine and alternator. So I get on line and see I’m not the only one with this issue. My main concern is I’ve always gone to my car dealership to get oil changes and not once have they ever told me after putting my car on the machine that they found an issue with neither. And again this has been going on for quite some time. My issue is now my warranty is out and it just so happen to just have ran out after my last oil change and again this was going on then and they never mentioned it. What are they going to do about this problem.
