NHTSA complaint #11765280

Owner complaint summary

I have tried without success to have Nissan Consumer Affairs assist me with an ongoing issue with my vehicle that started in February of 2026. The check engine light coming on and sending various codes related to system too lean. It was repaired in March of 2026 only to come on again this past August of 2026. Dealership in Crystal Lake Illinois M'Lady claimed it was repaired only for the light to come on again. They still are not sure why it's happening. They've had master technician from Nissan come and still cannot resolve the issue. The case manager at Nissan consumer affairs is extremely rude and unhelpful. She refuses to help me get the outcome desired with this case. She hasn't even bothered to contact the dealer where my car is to inquire about the updates or services done to the car. I want an early termination of my lease so that I can get a vehicle that is in working condition. I'm paying almost $600 a month on a vehicle that isn't safe or functional. Please help me get this resolved as consumer affairs is unwilling to act with efficiency and professionalism. Thanks
