“Vehicle oil pressure dropped to 0, check gauges light came on. I pulled over to park and ride lot and turned vehicle off assuming loss of oil pressure. Waited 15 minutes and tried to start it again, would not start. Checked oil dip stick and discovered antifreeze mix, opened oil cap and saw coffee-colored mix. Dealership I had it towed to at the time stated at cylinders 3 & 4 had cracked, was not owners fault as this was a common issue with cylinders heads with casting 0331. Would not repair as it was not a manufacture recall. Meanwhile vehicle is inoperable. …”
