Vehicle randomly does not start. When key is turned to position one lights, radio, windows, indicator lights all work as expected. When key is turned to start the engine nothing happens. The engine does not turnover or even attempt to turnover. The battery was replaced the first time this happened in April 2018. At that time I had the alternator and starter checked both were functioning properly. After repeated attempts to start the vehicle it has always started, eventually; it can take anywhere from 2 minutes to 30+ minutes for the engine to engage. When it first started occurring it happened pretty often. Prior to last Friday it had been a couple months since it took more than 30 minutes to start. I took the vehicle to another mechanic yesterday. Again starter, battery, alternator are all functioning properly. The mechanic mentioned that this model is known to have issues with the ignition and that I should contact the dealership, they may know what it is exactly. I've called two dealerships today, both say they know nothing about ignition problems in the vehicle.
Car will not start. Have battery, alternator, and started all tested and are good. Every so often go to start the car and when you turn the key to first position everything turns on. Windows work, radio works, light on dash turn on. Go to start the car and it does nothing. Does not even try to start the starter makes no noise. You just here a clicking noise. Was told be dealer that it might be inhibitor switch (range switch), that was replaced and a week later it again will not try to start. If you let it sit and come back a day later many time it will crank right over. There are many forums online with the same issue from this model.
