Good afternoon, I just purchased a 2018 Compass Limited with 35, 000 miles. I also purchased extended warranties. After only having for five days my son was telling me about hard downshifting between 25 and 35 miles per hour. I took it for a ride and it happened but not every time. I went back to dealer and of course it didn't happen while they drove it but they are telling me that it is normal. The Carfax report stated that the powertrain control module had been reset four times months apart. Any insight would be greatly appreciated. Thank you!!
