The folks here are correct… the dealership should not be telling you to drive with a misfire as it will cause further damage. Whatever you do get everything in writing as you will need it later if legal action is required. Misfires fall under both lemon law and clean air act protection. Emissions components have a much longer warranty period than just the standard manufacturer warranty.

Yes that’s too much

Pretty sure the master cylinder was the source of a recall on this car… might want to search that on NHTSA website

I agree with the advice from others that a torque converter could be the issue but if it were my car I would take a hard look at main wiring harness moving when the car is put in gear. Engine assemblies move to one side when a car is put in drive or reverse and they usually move opposite ways depending on the gear. I would start the car in park with brake on (be safe) and with it idling do a basic and methodical “wiggle test” where you start at a point in the engine bay and give each harness and connection a “wiggle” to see if you can replicate the stalling. It could be as simple as an air intake hose has come loose but I doubt it.

Need more info… what kind of car? Can you post a video of the start/stall thing? Does it start each time then die right away?

Hub has to come off

2 different codes but likely one core issue. The fact that the engine oil was so low it wasn’t registering is the first concern. A quart every thousand miles is a lot of consumption. Do yourself a favor and do a proper oil change and monitor the level closely for a month. Check it weekly and see what the use really is. Most likely you have a vacuum leak which is the P0171. Pretty common issue. If the oil is really dropping as much as the tech notes say, you either have a pretty good external leak which you will see bu looking under the car or it’s being burned which is a much bigger problem. A leak down test will confirm this. Just so you know… P codes are federally mandated for all car manufacturers and they are the same for every car made since 1996. In other words a P0171 has the same diagnostic path for a Chevy Silverado as does a Lamborghini. You can look these up on the internet for clues but not exact diagnosis.

No

Nope not one bit… I found fixing and diagnosing cars to come easy to me. Went to college at night and got my degree then spent last 30 years as OEM representative.
