“Constant smells of carbon monoxide in my vehicle almost every time I accelerate above 3500 RPM. I've taken it to two dealerships more than three times for the same problem with no solution. Every time I get in my vehicle I dread smelling this stuff and hope it doesn't affect me or a loved one.”

NHTSA complaint #11298227, filed 2020-01, 38,000 miles

“It a new car that I bought to avoid the same problem in a 2016 Ford Explorer, because Ford never solved the issue, and this one Ford Explorer 2018 has the same things, a bad smell in side the car when accelerated. Ford is putting our lives in jeopardy, I wonder if they already have an effective solution to this problem”

“Exhaust fumes are entering the cabin during acceleration and when the AC is on. Several family members have complained about the smell within the cabin. I personally have experienced headaches and burning eyes because of the issue. It smells like burnt hair. This is a family vehicle used to transport my entire family including my 5 month old baby. This smell is making everyone nauseous.”

“When climbing hills and engine at high RPM I can smell exhaust in the cabin portion of my vehicle. I initially thought it was the vehicle in front of me, but it happened again a few days later when I was traveling through the hills again. Same circumstances, climbing hills at a high RPM. Speed was approximately 65 MPH. The smell was exactly the same as if I was walking behind the car in the morning after staring the engine.”

“Hankook tires - 255/50r20 105h venus s1/s2 - had only 2/32nd tread after 21,000 miles. These tires came on my 2018 Ford Explorer, which I purchased new. Both Ford and hankook tires knew about the accelerated wear issue when I purchased the vehicle, but neither company made me aware of it.”
