In owners' own words
I was driving home from the grocery store going roughly 40 mph. I turned into a turn lane going into our neighborhood and started to press the break. Instead of breaking my car accelorated. It happened quickly, maybe 2 seconds. But it was very concerning. A warning flashed on my dash board that said, "break accelorating." I continued to push the break and started to slow down.

My van been giving me some weird issues lately. When Iâm going downhill, my brakes donât seem to work well! I have to push it all the way down, like a spongy. It doesnât break until I put on the emergency brake. the seat broke only weighed 185 pounds! the wiper blades donât do a great job cleaning the driverâs side after I bought new ones.

Occasionally the brakes seem to stop working briefly, and the van even accelerates while the brakes are engaged. It happened again today but has happened since we got the van new in 2021. The dealer cannot replicate the problem. The problem is discussed on this thread: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) Service brakes
