NHTSA Complaint #11072184 — 2018 CHEVROLET COLORADO

WHILE DRIVING HOME, YELLOW CHECK ENGINE LIGHT CAME ON & I NOTICED REDUCTION OF OIL PRESSURE. PARKED IN DRIVEWAY, SHUT OFF ENGINE, WENT INSIDE. UPON RETURNING, NOTICED SIGNIFICANT AMOUNT OF OIL ON DRIVEWAY. DIPSTICK SHOWED NO OIL. TOWED TO DEALERSHIP. THEY VERIFIED LEAKING CAME FROM DEFECTIVE OIL COOLER LINE HOSE. WAITED SEVERAL DAYS FOR REPLACEMENT PART. THIS IS A NEW 2018 COLORADO Z71 WITH ONLY 5K MILES ON ENGINE. AND, THIS IS A SYSTEMIC PROBLEM THAT GM HAS KNOWN ABOUT SINCE 2015 AND IMPACTS BOTH COLORADO AND CANYON MODELS (THERE ARE SEVERAL COMPLAINTS ON WEB). THIS IS A DANGEROUS PROBLEM AND SHOULD BE INVESTIGATED BEFORE SOMEONE GETS HURT. IT WAS NOT A SLOW LEAK. OBVIOUSLY, IT IS MANUFACTURING PROBLEM. ADDITIONAL INFORMATION (INVOICE AND PICTURES) AVAILABLE UPON REQUEST.
