What owners say about the electrical system
Verbatim from NHTSA complaints, newest first
“The contact owns a 2018 Ford Focus. The contact stated that upon starting the vehicle, and while driving at various speeds, messages that the brake fluid level was low, and to shift into park were displayed. The contact stated that other unknown messages were displayed. Additionally, the contact stated that upon turning off the vehicle, the instrument cluster and the infotainment system screen failed to turn off intermittently. The contact stated that the vehicle had also experienced abnormal battery drainage. The vehicle was taken to the dealer, where it was recommended to replace the negative (-) ground wiring cable. The vehicle was repaired; however, the failure recurred the following day. The vehicle was taken back to the dealer, where it was diagnosed and determined that the TCM had failed, and the failure could be the cause of the battery drainage. The dealer determined that the TCM needed to be replaced and ordered the part. The vehicle was not repaired. The contact related the failure to an unknown recall. The manufacturer was notified of the failure, and a case was filed, but no assistance was provided. The failure mileage was approximately 106,000.”
“The rear view camera went out on our 2018 Ford Focus some time ago. I read recently there is a recall for the camera issue with Ford trucks. I am wondering if other consumers have complained of issues regarding the camera going out on Ford Focus 2018 cars”
“After working on [XXX], my vehicle made it home, and wouldn't start. After jump starting, I began to drive it to the dealership. My safety, and others, was put at risk when the car began to smoke, lost power in a driving lane, and then burned down with extreme intensity. The dealership isn't helping. Ford said their Office of General Council is still looking into it, but originally denied my claim before saying they would reconsider my case. An official report from the Lakeland Fire Department stated mechanical failure and loss estimated to be equal to $10,000. The engine light blinked on the way home, the oil lamp went off and on, and then the car wouldn't start. These were the only signs prior to a total loss of power and smoke before my life was in jeopardy.”
“I bought this car it was used by two other owners. I bought a new battery for this car but there is some kind of electrical problem with smell coming from vents and the radio system keeps shutting off.. keeps giving me a message on the screen that says shit off admission or restart engine to save battery then my whole radio system turns off till I turn off my car... Also now it time 4 tries to start my engine. Dash board will turn on but not engine..”
