Check engine light comes on p06dd. Initially it was a oil injector that needed replacing within the first 4 years of purchase of a new truck. When the code comes on later it's the oil pump. Oil pump has a pressure switch on it that says pump oil at 10 ppm, if it goes at 7 ppm it will cause the check engine light to come on. The oil pressure going into the engine at 7 ppm is not s serious issue and shouldn't cause the check engine light to come on. I live in a state county where you can't register your 1500 truck for a new vehicle registration with the check engine light on. The dealer wants to bill me 10 hours of labor because of where the oil pump is located inside the engine. The local dealership wants to charge $1,000 for the replacement fo the oil pump and the connected sensor. I would like to see a recall effort happen which will not make the sensor enact the check engine light for small irreverent discretion with the pressure switch.
Truck under 52,000 miles, had all known recalls (6) performed at cliff anschuetz. All maintenance performed within manufacture specified guide lines here also. Truck never displayed error code or service engine light since purchased new. Driving home from work 45 miles an hour March 6, 2019, engine message displayed with beep tone: oil pressure low turn off engine. I immediately pulled off, let truck sit for 5 minutes. No oil or fluids where leaking. Oil appeared normal and at proper level, did not smell burned. Started engine error code was gone, drove 1 � miles to auto repair shop. Same error message appeared after going 100�. Auto repair shop gave me bad news 3 codes: 1) p0324 knock sensor, 2) p0521 engine oil pressure performance, 3) p06dd engine oil pressure control solenoid valve stuck off. Went to feldman Chevrolet of highland, technician told me this should be covered under warranty, lakeside towing delivered my truck there. Feldman will not cover repairs stating out of warranty. Will give me $2000 dollars off on certi rebuilt motor, my cost $7,200 w/12 month warranty. Not acceptable. Salesman there offered me $8000 as trade in. Working with gm complaint department, they have been given all information. Been nice but seems like I am caught in middle between her and service manager at feldman. As of, 4/30/2019, I am awaiting a call back from gm. This is a known defect in this engine described in so many blogs! google 2014 chevy Silverado 1500 engine failure. Vacuum pump only warrantied to 36k, 2016-17 trucks only have a 60k powertrain warranty. Tells you something, gm dropped powertrain warranty down to 60k for 2016-17. This is not common problem, only a matter of when the vacuum pump fails. Pump fails, starts pumping metal debris back into oil/lubrication system taking out the oil pump then the engine. I owe feldman $970 for tear down and for removing oil pan!.
