Message: <blockquote data-quote="unillenium" data-source="post: 14409" data-attributes="member: 2841">I have a 2012 2.4L FWD. Purchased Brand new. Had the timing chain replaced once early on in the vehicle's life. Along with the catalytic converter . Ended up getting scammed into paying for a throttle body service when I brought it in for that. Later on it developed problems again that seemed similar to the first time and I brought it in and the camshaft actuator solenoid valves were replaced under warranty but the stealership told me I needed a throttle body because I was having issues with my throttle position sensor and that it wasn't covered under warranty. They also cracked my oil filter cartridge cap and charged me 25 bucks to replace it when changing my oil. By this time I was wised up and had already purchased my own OBD II code reader so I could call out their bull. But nonetheless I was charged a 60 dollar diagnostic fee because they "found something" not covered under warranty. By that point I still had just over a year left on the powertrain warranty but had had enough with the stealership insulting my intelligence. Started taking care of my own scheduled maintenance. Oil consumption seemed to be less of an issue when I was doing it myself. No idea why. If I had to guess I would say that they are under-filling the oil and I'm just trusting when I go to a dealership or a Mr Lube that they know how to look up a car's engine oil capacity. So the oil loss gets a head start when they change it. Last winter had intermittent error codes for misfiring that went away when the weather warmed up again. Still yet to figure that one out. This summer the car started behaving as it did when the camshaft actuator solenoid valves failed that one time. I checked the oil immediately and saw that I was down a quart (checking that terrible excuse for a dipstick is a science in and of itself). Added a quart of oil and the issue gradually improved on it's own and has been okay ever since. Just have to be extra vigilant with oil levels. So if I had to take a stab in the dark I'd say that even when the oil level is showing in operating range (but down) the first place the engine loses oil pressure is at the solenoid valves and this cascades into issues with the timing chain tensioner and ultimate self destruction of the valve train. Either way the behavior of car dealerships these days is literally criminal (It's a federal crime in Canada for a car dealership to try and sell you unnecessary repairs/maintenance) and it will probably be the last time I buy a brand new vehicle or a GM vehicle. Bonus round went to do my first at home air filter replacement the other day and found that one of four screws on the air filter housing was missing and that there is a small amount of air bypassing the filter by that means. So either Mr. Lube or the Dealership lost it and never felt the need to inform me. Seriously consider trading up to a bus pass this winter.</blockquote>
