| Description of the problem | In feb 2020 my sonata went into safe mode after exiting highway and dealer ended up replacing "knock sensor". In december 2020 my engine "stuttered" throwing me forward as if i had hit brakes hard. No warning lights or messages occurred and after a few seconds car acted normally mostly. A few days later after exiting highway again the engine warning light (orange) came on along with error message "possible condition with engine control system" has been detected. Car did not go into "safe mode" and seemed to be operating normally. I contacted dealer who assured me safe to drive over hundred miles back to dealership in this condition to check. I drove back from east coast fl to west coast fl to turn car in. I believe engine issue experienced is related to the theta engine issue and repair would be covered under settlement. Dealership disagrees and has indicated issue is with fuel pumps (both are being replaced) and charging me $2300. |
