NHTSA Complaint #11514506 — 2019 CHEVROLET EQUINOX

This vehicle has started to lose power was taken to firsteam Norfolk Va where purchased took for oil change and tire rotation also loss of engine power at speeds of 20-32 mph and 50-62 mph. Dealership at Norfolk Va sent to firstteam Hampton VA Chevrolet for diagnosis and came back no engine light and small misfire 3/4 sparkplugs needed changed 177.00. After plugs were changed still had misfire then they felt it was number 4 injector 500.00 but never did work. I took it to national shop for recommended injector and when plugs were pulled mechanic found no new plugs. Injector was replaced with gm part and still misfiring. Norfolk firstteam towed vehicle back to Hampton Va firstteam and they are now giving me the run around. They want a blank check to replace parts till they find the problem. Unexceptable to even ask. Service writer has been very disrespectful and hung up on national shop and myself. When asked questions regarding work done service writer would just talk over us and speak to us disrespectful and then hung up. We have requested service manager at Hampton firstteam Chevrolet contact us and we were told she would tell him later. I have contacted Aston Lewis Jr owner of all firstteam dealerships here in Va requesting help three times and still no response. We need this reported so someone can fix the misfire and power loss the dealership does not know how to fix. Car is under power train warranty . Any help would be nice.
