Around 08/22 backup camera failed and now there is a dent in the tailgate area. I have documentation from the dealership, finally that the backup camera was not working properly. On about May 23, 2023, I stopped at a local grocery store for just a few items. When I came back out my car would not even attempt to turn over (approx. 24,000 miles). Had to wait three hours for roadside assistance to use a jump box to get it started (would not jump-start like a normal vehicle). The next morning it was dead again, and I had to call an Uber to get my child to school, not acceptable. I took it to the dealership again, and after three days they replaced the battery.....I had not even owned the vehicle for two years, it had 6 miles on it when I bought it, and it needs a new battery? Now it is 09/22/23, the dealership has had my car since the morning of 09/13/23 and I still don't have it back. …

Since the purchase of the Bronco Sport in 2021, I have intermittently taken it in for required service. However, there have been times when I have had to take it in for hearing noise coming from when I make turns, and it sounded like my break pads were making the sound of wear. A recent report did address the break pad concern, and they were replaced. Intuitively something told me to check my fluid levels and the engine air filter, along with the cabin air filter. They both needed replacing, which I did on my own. The mechanic who put on my break asked me questions about the Bronco, I explained to him that I was having issues with take off, and have had to take it in for recalls since make the purchase. He asked me to open the hood. What he found was oil leaking around was oil leaking around my turbo. I was shocked. Because it had not been long since it was serviced. …

I purchased the 2021 Ford Bronco Sport in August of 2025. There were issues after about a week with all kinds of messages of components not working cycling through constantly on the display. The electric brake would engage on its own while parked and had to be shut off before I could go forwards after starting the vehicle. I took it to the dealership where I bought it and after a few days they said it was a batter issue and replaced it at no cost to me. It worked okay for a short time and then I had the same issues and now added to those were it wouldn't start for at least 15 minutes and several tries. Cruise Control could not be used and the turn signals would not work while all of the messages were displaying. The windshield wipers would only work at the highest setting and the rear wipers would not work at all. …
