Has carbon monoxide in the cabin on highway driving . i have a co meter as i have had the car in to dealer 7 times for same issue & it is still not fixed. they now claim it is ok but still have 15 ppm in 10 minutes of driving on highway and level still rising. they say this is an acceptable level. i open windows & co level drops to 2ppm. then close windows & meter reads again in 15 min 15ppm. this car is not safe. & lincoln will not take it back. please contact me & take car for testing if you wish i have 3 months left on lease .then someone new will die driving this not knowing this issue. this has been going on for 2.5 years does not have issue in city driving meter does not move over 3ppm . only on highway driving. even more when climbing grades . levels go up to 15ppm in 5-8 min. then of course i open windows. last fix 8-15-19 they claim to have fixed a bad back door seal. did not change levels when driving on highway same .
