Took vehicle into dealer for a recall on October 17, 2023 with the recall being [Primary]: RECALL : C/S: N192268181 -TAILPIPE EMISSIONS - EXHAUST COMPONENTS: C/S: N192268181 -TAILPIPE EMISSIONS - EXHAUST COMPONENTS. The dealership did an excellent job on the work providing a video to show work being done. Now this month of April, I received another check engine light stating the P0013 code stands for “Exhaust “B” Camshaft Position Actuator Circuit/Open (Bank 1).” There is not a recall from the manufacturer but according to dealership they've received a bulletin in regards to this issue. According to the dealership it will cost in excess of $500 to repair. Absolutely not true. There are a thousand videos on what causes this and even how to repair it from the same mechanics that work within these dealerships. This issue is a safety issue because if not repaired it causes damage to your engine. This code lets you know that you will start experiencing loss of power, trouble starting your vehicle, the stalling/picking up speed all at the same time. Some of these issues have been caused from the issue of the oil consumption problem associated with the Terrain's.
Very high oil consumption. I recommend it's the piston rings
Evap emission control leak detected As the check engine light comes on, when hooking a computer up to the car for a scan it pulls a code stating there is an evap leak. The gas cap has been replaced along with a sensor and no gas is seen leaking but you can smell gas vapors when the car is running and fuel mileage is terrible. Also the stabilitrak has been an underlying issue since owning the vehicle
MY DAUGHTER WAS DRIVING TO A FRIENDS HOUSE. SHE LOST ALL POWER, AND THE VEHICLE WOULD NOT START BACK UP. THERE WAS 3/4 TANK OF GAS IN IT. WE HAD IT TOWED TO A NEARBY SHOP TO HAVE IT LOOKED AT. UPON THE VEHICLE LEAVING IT HAD A LOT OF GAS ON THE GRAVEL ROAD. WHEN IT MADE IT TO THE SHOP THERE WAS OBVIOUS FUEL LINE ISSUES. THIS VEHICLE HAS NOT BEEN FIXED YET, STILL WAITING ON A REPLACEMENT LINE FROM A DEALERSHIP. THIS IS SOMETHING THAT GM SHOULD HAVE HAD RECALLED AND FIXED IMMEDIATELY. THIS MIGHT HAVE BEEN AN ISSUE THAT WOULD HAVE BEEN FIXED DUE TO IT STILL UNDER A MANUFACTURERS WARRANTY, BUT I DO NOT HAVE ACCESS TO THAT. THE SHOP WHERE THE WORK IS GOING TO GET FIXED AT SAID THIS WAS COVERED UP TO 150,000 MILES. IF THIS WAS AN ISSUE TO THAT MILEAGE, IT SHOULD BE EXTENDED TO THE LIFE OF THE VEHICLE.
The contact owns a 2012 GMC Terrain. The contact stated that the vehicle stalled at various speeds, and now was stalling while accelerating. There were no warning lights illuminated. The contact took the vehicle to a certified mechanic who linked the failure to excessive oil consumption. The fuel pump was replaced and oil was added. The contact stated that the failure reoccurred the following morning. The check engine and oil service warning lights were illuminated. The oil level was low. The contact stated that the oil was changed almost every 3-months. The dealer was notified of the failure and informed the contact that the VIN was not included in a recall related to the failure. The vehicle had not yet been taken back to the dealer. The manufacturer was not made aware of the failure. The approximate failure mileage 75,000.
AFTER STOPPING AT MAILBOX THE LOW FUEL ILLUMINATED, THE FUEL GAUGE INDICATED EMPTY. THE TANK WAS HALF FULL PRIOR TO THE 12 MILE TRIP HOME FROM TOWN. NOT SURE WHEN THE PROBLEM OCCURRED, BECAUSE IT MIGHT HAVE TAKEN A FEW MINUTES TO PUMP OUT 8 OR 9 GALLONS OF GAS, HOWEVER IT WAS ON THIS12 MILE TRIP HOME. 6 MILES OF HIGHWAY AT 55 MPH AND 5 MILES OF PAVED COUNTY ROAD AT 30 MPH AND 1 MILE OF GRAVEL ROAD AT 20 MPH. AFTER THE LOW FUEL INDICATION THE ENGINE WAS STOPPED, FUEL WAS ADDED FROM A CONTAINER, AND WHEN THE ENGINE WAS STARTED THE FUEL STREAMED OUT ON THE GROUND. THE VEHICLE WAS TOWED TO A LOCAL REPAIR FACILITY, BECAUSE IT WAS CLOSER THAN THE DEALER. GAS LINE AND CLAMP WERE REPLACED. THE MECHANIC INDICATED THE PLASTIC GAS LINE AND PLASTIC CLAMP WERE HANGING LOW, AND NO PROTECTIVE COVE OVER IT. *TR
