2017 Ford Expedition EL service brakes problems

“brakes were functional at time of parking suv. upon reentering and starting vehicle, the add brake fluid light and alert came on. the brake peddle was non existent with feel. the brake reservoir was empty but no visual leaks from any of the brake calipers or lines were evident. after refilling the brake master cylinder to the full line. the fluid again drained to an unknown location with no visual leaks.”

“On [XXX], My 2017 Ford Expedition suddenly lost all brake fluid in the master cylinder, where it drained into the Brake Booster. We had no braking function whatsoever. I filled up with another quart of brake fluid, drained into brake booster as well. The vehicle was towed to the local dealer in Lagrange, GA, where the work was completed on 7/8/2024. I was preparing to drive my family home to FL when we noticed the issue. We had to stay an extra night in the hotel. Thank goodness we had not been on the road and were only leaving the hotel. There is already a recall for the same issue, with vehicles made through 1/31/2017. My vehicle, by VIN, was made on 2/3/2017 at the same plant. Ford is refusing to acknowledge the issue.”

“Brake master cylinder rear seal failed and engine vacuum drew all fluid from reservoir into brake booster as vehicle idled in park. Both front and rear brakes were inoperable because one reservoir serves both systems and that reservoir was emptied by engine vacuum. Pedal went to floor with zero brake actuated. At highway speed this would result in a severe accident due to the rapid loss of fluid with no prior change in braking effort. Vehicle could only be slowed with parking brake. Ford dealer service department inspected and confirmed loss of fluid into booster. Brake warning light and low fluid message displayed as reservoir was drained by engine vacuum.”

“Brake Master Cylinder is LEAKING out the back of master cylinder and into brake booster, lost almost ALL of the brake fluid in short trip as soon as it started.. Its an Identical issue to current Recall 22S11 or 22S14 on many if not all 2016 2017 Expeditions. My truck was built at the same Kentucky plant that produced the trucks with this exact issue, build date [XXX] built in the same time frame the trucks have the issue . But Ford reports it as Not a recall.. Its Doing the EXACT SAME issue that is part of recall 22S14 and 22S11.. and is an incredible huge Safety Risk causing potential death to the driver or other motorist if the truck runs out of brake fluid ..”

“Near total loss of brakes. Pulled in to a parking spot and brakes very squishy, upon returning brake light was on. No indication of brake fluid on ground. Added approximately 25oz of fluid topping off reservoir, upon returning home (1.5mi) the pedal travel was much longer than normal, and no fluid remaining in reservoir again. Replaced master cylinder and power booster. Upon removing the power booster was full of oil.”

“While driving down the highway, the low brake fluid light sounded and the brake light came on . we slowly loss brakes while driving down the HWy. We added brake fluid, which there was no brake fluid in there at all .When we added the fluid, we pump the brakes and they tighten . Shortly after adding more fluid , the fluid and brakes were gone and white smoke came out of the tail pipe. We never could see exactly where it was leaking at. We added about a quart and a half of fluid . After adding the more fluid, we managed to get it up to the dealership where it was purchased . We explain to what was going on and he knew of the situation because he said it was a recall last year on the master cylinder if I’m saying it, right. I told him that we never received a recall letter but we left the vehicle and he did research by our Vin number, and said we were not part of the recall, but I read a recall number 22S14 about the break failure in expeditions. We called the local number attached to the recall and they once again told us that our vehicle was not part of the recall because I guess it was not out of the Kentucky plant . We are having the same issue with our…”
