NHTSA Complaint #11702955 — 2024 NISSAN ALTIMA

This incident happened twice in one week first with 2023 Nissan Sentra then replaced with a 2024 Nissan Altima both rented from Enterprise. I was traveling down the street from my house, a two-lane, steep hillside road, which I’ve traveled up and down for 30 years. I stopped behind a parked car on the right side of the road to let another car come up the hill and pass by before I continued down. As I continued down the hill, the car just began to accelerate and I could not stop it, I tried to break, but no response and the car kept accelerating for about 50 feet before crashing into. the granite hillside, lifting the car so it landed perpendicular to the road, setting off all airbags and blocking all traffic completely. Thankfully there was no other damage to other cars, homes or people, which was a minor miracle.To reach such an impact speed in such short distance suggests some kind of mechanical failure. My insurance paid for a replacement rental, a 2024 Altima and on my first drive down the hill, in the exact same spot, the steepest of the road, the exact thing happened, rapid acceleration and no breaks.
