When you turn the igntition to start did it crank the motor?
Yes
Did the starter engage the motor or did it just spin?
The starter motor was revving.
As in, did the engine make it's usual 'chug, chug' cranking noise or was it a much different and higher pitched spinning noise?
No. No noise, no shuddering.
If it cranked but didn't fire it'd most likely be the CPS or a fuel problem. But if it just sat there and spun the starter motor then it'd be the start solenoid or its relay.
If the starter motor is turning, isn't there a belt or gear which connects the motor to the engine? Why would a solenoid or relay come in the picture?
There's a BIG difference between cranking the engine over and just spinning the starter. They're nothing like each other and not something easily confused. So which actually happened?
AFAIK, the starter motor was turning bu the engine was not "chug chugging".
Since it's new you should of course make the dealer fix it.
I will go to the dealer. It is time consuming, the dealer tries to weasel out of what they can, hence I want to go there informed. Thanks four your insights.
