Problems again 2018 kicks. Car would not go over 100 then when I park car would not restart battery dead until I get boosted. First dealer stats it’s my engine air filter. Battery is fine (they say). Got all fixed driven a week cold snap happens and it does the same. Different dealer states I need a new battery! Both charge me for a diagnostics of $125 each I’m pissed don’t they’ll work for the same Nissan this was within a week. So question would bad battery cause my car to not go over 100??
