Car is having trouble initiating with push button start. It at times deviates and eventually turns on. The car has 60k miles and just brought it to Infiniti and ran diagnostics and said car is fine and they updated the computer. I changed the battery yesterday and turned on fine better. It snowed in my area last night and was 10-15 degrees and the car barely turned on this morning. I have a video and can send it via email as the file is too large. Plz help
