2008 Ford Escape Hybrid: 000 miles..the highway at about 65 MPH..pull

Would this be related to the powertrain light intermittently going on and off over the past months? Why also aren't any codes stored by the system the light goes off so a technician can detect was the issue was vs. saying there is nothing wrong now. Is there a manual inspection that can also be completed to confirm that a major powertrain failure hasn't occured?

Thanks, XXXXX XXXXX question, do you know if the computer or software update would be covered under the powertrain warranty?

Sorry, to bother you one more time. Just to confirm, the Escape computer system should have logged error codes each time the Powertrain light came on. I am asking as the last technician that looked at this in February before it broke down said "no codes in any modules found". At this point, the powertrain light had gone on about 2-3 times over a 21 day period....and went on a total of 10-12 times of 3 months before it broke down today. I'd also like to know about any other tests (manual reviews) that could help find an issue if there were no codes. Example: at the same time we took this car in the breaks were skipping between 5-15 miles per hour. We took the car in 3 times and all technicians said "there is nothing wrong with you car". We found on a blog to manually look at the toner rings as one or more were likely cracked. We took it back, 2 were cracked and the problem no longer exists. I am starting to worry that this car computer system is not functioning properly and Ford doesn't train anyone on how to manually inspect certain issues when the error code doesn't show up.

Thank you,
Kate
