I have had the code once but cranks fine.
You can use a scanner to read the code without clearing it. Dealer would never know you scanned it - not that it matters... Dealer cannot deny warranty repairs because you read the code.
That's like a doctor saying your health care provider denied your claim to treat your infection because you checked your own temperature.
