Check Engine Light On problems of the 2017 Nissan Sentra

The car was in motion when I loss 90% acceleration and velocity while driving. Very, very scary! I was on the highway when this occurred. I proceeded to check the battery, alternator, and starter by aaa when a service call was placed to inspect the vehicle at my home. Aaa's. They informed me that the battery, alternator and starter are great and that these things were not the reason why the check engine light came on and has remained on. The car is only 3yrs 11mnths old. I get the standard oil change but Nissan has discontinued to use conventional oil. Which is the recommended oil for my car. I also get the car serviced as needed. It is extremely dangerous to drive my car. I cannot drive it period. It suddenly loses power 60 to 120 seconds when the car is in motion.

Purchased my car in Aug. Of 2017. Jan. 2018 was the first of 7 times I have taken my car in for the check engine light. Case is at Nissan north America in arbitration where they want to �compensate� me $1500 to essentially shut my mouth. There is a significant lag in the acceleration not only from a standstill , but also while in motion trying to accelerate to higher speeds. The car will not go faster than 55 mph up a hill. When the car is on slight inclines the vehicle loses power in attempting to climb and the engine tachometer readings climbs well above the designed rpm specifications. This happens on level ground. When accelerated from 45 mph to 55 mph the tachometer would approach 6000 rpms prior to switching gear. It doesn't occur 100% of the time, the vehicle consistently reaches close to 6000 rpms prior to shifting to a higher gear. As I drive I also start to notice a burning smell. My car is consuming excessive fuel compared to another �loaner� 2019 Nissan Sentra sv which has the same exact specifics. My car requires 3 times the fuel to drive a similar distance. When telling Nissan consumer affairs this I was told �this is normal because my car is older and has more mileage on it. � normal wear and tear over a 2 to 3 year period would not account for such a disparity in fuel mileage. Nissan tech support has physically gone to the dealership to try to fix my vehicle and I since taken it in on February 10 for the 7th time. Nissan called because my arbitration poc didn't call them like she was supposed to 4 days ago so now my vehicle sits at the dealership because they don't know how to fix it. . My vehicle is not safe to drive on a public roadway or to transport my 8yo. I have submitted my case to the attorney general's office and bbb auto-line claim. I just want to be in a safe vehicle. I have all the service docs but file is too big to attach.

Tl the contact owns a 2017 Nissan Sentra. The contact stated that when the vehicle shifted from 2nd to 3rd gear at approximately 30 mph, the vehicle hesitated. The contact then stated that while driving at highway speeds while accelerating, the rpm revved up to 5,000 rpm and the vehicle failed to shift gears as designed.
