OK, had my 2018 QX30 since end of Oct 2017. Tonight on my way home, car was stopped at red light. It started to studder like it was going to stall. Kept pressing gas pedal and it was going really slow and almost hesitating. Check engine light started to flash and then stayed on. I was about 2 miles from home and was able to limp back home. Called dealership and told them. They wanted me to either drive in or have it towed. Shut off engine, turned back on and it seems ok now. Haven't driven it since. I will drive (hopefully) to dealership tomorrow am. They had no loaner cars and wanted me to rent one myself. Finally convinced them to provide a rental for me. Anyone else had this issue?
