Bought a truck from dealership that came with problems…

So recently about a week ago today, I bought my first truck, a 2014 Chevrolet Silverado 1500 from a dealership. I was happy until the next morning. The check engine light came on while I was on my way to work, and then after work, I took it into AutoZone to check what the problem was. AutoZone told me it needed an oil pump replacement, which is around $500. I called about five mechanic shops, and they told me the estimated price including labor would be around $1500-$2000. That’s about how much I put down for the truck. I was pretty pissed, so I called the dealership, and they told me since I signed an ‘as is’ paper, they wouldn’t be able to do anything. It’s all on my end from there. When I was buying the truck, shouldn’t they have told me that? I’m assuming they cleared the check engine light before taking the smog check. Is there anything I can do, or am I stuck with this bill?

As is is exactly that. Many people have a trusted mechanic inspect before purchase. He can tell you if the codes have been reset.

What’s your oil pressure reading? Typically, the oil pump issue is from the pick-up tube’s little O-ring losing its seal, causing low oil pressure.

Oil pressure reading at about 50.

Life lesson here. Buying a used car means buying the previous owner’s maintenance history. Never buy used from a dealership. Private party. Get a better deal, perhaps run into a fellow enthusiast. As far as financing, your bank or credit union will lend you money at a much lower rate. I would start with a fresh oil and filter change. Who knows if the correct oil is in the truck? Considering this is a GM vehicle, invest in your own code reader or preferably a scan tool. Also, what engine exactly? Owning GM cars is why I bought a scan tool a long time ago.

50 psi at highway speed?

No, just after turning on and sitting for about 10 minutes.

Steady? Sounds pretty good. What exactly were the codes given?

They didn’t give me any codes, just a printout that says ‘most likely solution: replace engine oil pump.’

Drive it until it comes up again. Go to an actual shop and pay their $80-$120 diagnostic fee to get the code. 50 psi at idle is perfect; go with a definite answer, not an AutoZone guess. It’ll be cheaper in the long run.

I’d ask the dealer if you got the repair done with them if they would be willing to give you a discount on the service. Yeah, it was an as-is purchase, and they aren’t required to do anything, but if they care about their customers, they might help you out at least.

Trouble with this series of engine is that it is equipped with an oil pump that has an internal pressure regulation solenoid to help maintain proper pressure when this engine is in its Active Fuel Management, AKA 4cyl mode and variable valve timing. The solenoid is part of the pump and is mounted behind the timing cover on the front of the engine. Not exactly a quick swap.

This is great info. Thanks! Only 57k miles on my 2015, but it’s a 5.3 with AFM, and I’ve seen half a dozen LS-based motors have to have cam and lifters done due to AFM issues. Didn’t know about the oil pump though.

What you failed to realize is the paperwork said ‘as is.’ I bet you the window sticker had big font that also said ‘as is.’ Legally, the dealer is not obligated to do anything. Next time buy your car with an extended warranty, or at least find a dealership like CarMax that has a 90-day, 3,000-mile warranty when you buy from them.

50 psi is fine while idling as long as it’s not dropping off and saying you have no oil pressure or very low pressure. Aside from that, the gauge on the instrument cluster is connected to a glorified on/off switch. You’d need to find a way to hook up a gauge to get a good pressure reading. See if one of your friends may have a code scanner. If not, go by an O’Reilly’s and ask them if they’ll pull your codes and write them down.

P06DD is always an oil pump on that model year. The solenoid that controls the oil pressure is bad. In some cases, you can replace just the solenoid, but why go through all that work and not replace the whole pump?

So how much did they sell it for?
