Car stalls; engine impaired; oil consumption problem.
The oil consumption is out of control for their vehicles I've had more oil changes that I've ever done on a vehicle I've done oil construction tests and they always say it's just at the 1 quart that they allow who's is bull I've checked my oil cold and it's hardly on the stick and the oil light has come on numerous times I'm no genus but I do know it's more than a quart low when your oil light comes on. At 1,100 miles it was 2. 5 quarts low and I was forced to do another oil change when I only had 1,100 miles on this one. The first pic I've attached is cold oil level at 1,100 miles after oil change. The car only has 53k on it and I want to know how many times do we have to do oil consumption tests to get it fixed under the lifetime engine replacement and forget about the roadside assistance from Hyundai they tow 20 miles that's it and the rest is on you how is that fair when it's not your problem to begin with.
I was driving in another city and my car went into limp mode. I had it towed to nearby dealer and they said I was low in oil, after having it changed an month before. They did oil consumption test and found it to be 1 quart per 1000 miles and left there and 2 months later had another consumption test done after seeing my car was one in the class action on engine and bearings. They found this one to be 1. 1 qts per 1000 miles. Dealer said no way will they send info to get a new engine under warranty. A qt a 1000 miles seems very excessive. Dealer said that you need to be at 1. 5 qt per 1000 which would be almost no oil when I go have an oil change. The vehicle is only 3 years old and 100000 miles. This seems like too much oil to be burnt. And they know they have engine issues and will not rectify.
