Thanks for the info. My 15 quit about 50 feet from driveway when I was headed to Colorado to see daughter and grandson.
It would not give code, no warning of any kind, just cranked but no start, finally got it back yesterday after dealer had it 14 days,
when they test drove it after replacing the crankshaft sensor it spewed out 2 quarts of oil, they wanted me to pay $1,250 to replace rear main seal, took to a private garage and they couldn't find a leak anywhere, drove it 200 miles today and so far no leaks. Where did the oil come out from, nobody seems to know. LOL.
