| Description of the problem | Yesterday i took my car which had 30,852 miles on it to the dealer for the 30,000 mile maintenance. I was informed that there was a recall for an ecm & cluster software update that had to be performed. I was told nothing about the purpose of the update. The car was serviced, i left the dealer and drove approximately 2 miles to the grocery store. When leaving the grocery store i had to turn left across a lane of fast moving traffic approximately 200 yards away from a major intersection. As i proceeded my car stalled and i was almost hit. The engine did not die completely and i was able to limp back to the dealer. They gave me a loaner and said they would work on the problem. When i went home i did a substantial amount of internet research and determined that hyundai knows these engines are defective and there is another class action suit pending on the 2015 and 2016 models after they had already settled a suit on the 2011-2014 models. This morning the dealer stated they have to replace my knock sensor because its bad. When i stated i knew about the engine problems the service tech admitted my knowledge to be correct but said he has to go through the process which for now is to replace the sensor and harness which will not solve the problem of a defective engine that can stall in traffic from previously known problems. The software update is what caused my vehicle to go into "limp home" mode. This is a known defect to which i was not informed and i was almost killed yesterday. Hyundai knows this is a problem on the 2015-2016 and is further exacerbating the issue by installing software on a service recall that is designed to ascertain their exposure to defective vehicles. I was lucky i wasn't killed yesterday and now i have to go through a process that further risks my life and there are hundreds of thousands of vehicles out there with the same problems. |
