So the car has been great, except for one intermittent issue that is really bugging me.



On cold mornings, or if the car sits for 2-3 days, the car will start and then stall a few seconds later. I literally have to give it gas in order for it not to stall. No check engine, no other symptoms, nada.



The first time I brought the vehicle in, they switched the high fuel pressure pump. It did not solve the issue.



The second time I brought the vehicle in, they could not reproduce the issue. The car stayed on their lot for 10 days.



I brought the car in again two days ago and still haven't heard from them.



Winter is around the corner and I have zero confidence in this vehicle during the real cold months. I think I have a lemon, because every people I know who had a Hyundai never encountered such issues.



At this point I am quite fed up and I'm not really enjoying the vehicle anymore. I bought the BRZ 3 months later and you can tell the difference in engineering and the ease of maintenance and accessibility to components. The Hyundai is crammed, and even the oil chance is quite the pain in the ass. Had I known back then, I would have went with a Crosstrek or the Corolla.



My question is, if the dealership cannot figure out the issue, can you request the mothership (Hyundai Canada) to buy back the vehicle? It's a brand new car with 5600KM and this should not be happening that early. Have you heard any success stories regarding vehicle buy-backs?



Thanks for your time.

I would run a bottle of dry gas and/or injector cleaner. Sounds like it could be a little water freezing in a fuel line or a slightly clogged iniector somewhere. Is it a key start or a push button? If it's a key start make sure you turn it to on first, wait for the fuel pump to fully prime (you can hear it), and then turn it to start. If it's a push button I guess it should do that automatically. If neither of those work it could be the a PCM/sensor issue if it doesn't realize that it needs more fuel than it's giving. (This is a bit of an assumption but cold air is denser and needs more fuel so my assumption is you are running too lean at low temps). In summation I would think the issue is either the computer getting not all the right information, or it having the right information but the system not functioning the way it should because of something in a line somewhere. Start with the dry gas, it's a few bucks. I don't know Hyundais but Subarus seem to need a bottle of injector cleaner every 40k miles or so before they start running funny or even throwing codes. I know you have low miles but it only takes a little bit of water or a piece of dirt to get lodged somewhere to cause issues in any car at any time really. (Especially when the air is cold and dense and requires 3x as much fuel to start/idle)
