Dodge Dart spongy pedal problems

Filed Aug 10, 2026 · Brakes · KS

On June 11, 2026, I took my vehicle to a certified dealership to have safety recall R63 (the federal safety agency Campaign Number 15V‑800) performed. The dealership inspected the vehicle, claimed no oil was found at the break booster, and only replaced the vacuum supply tube, leaving the original vacuum pump in place. Recently, I experienced a sudden and total loss of power brake assist while driving, resulting in a rock hard brake pedal. Upon inspecting the vehicle myself, I disconnected the vacuum hose directly at the mechanical vacuum pump and found visible oil pooling at the pump's output fitting. I have captured this on video. This oil migration is the exact defect the recall is intended to fix, and it has now destroyed my brake booster. I had the vehicle towed to the dealership on 7/8/2026. However, the service manager is refusing to replace the brake booster and master cylinder under the R63 recall. They claim the booster failed for unrelated reasons, despite the physical evidence of the oil leak originating from the vacuum pump. The initial recall repair was ineffective at correcting the defect, and the dealership is improperly denying me the federally mandated safety recall remedy by attempting to charge me out-of-pocket for the resulting catastrophic failure.

There was no accident in this case. We lost brakes with no warning and the brake pedal got hard to press. So we changed brake pads and calibers in rear because had not be but few months on front brakes. Still no brakes they was then bleed to be sure and had little brakes and drove it home and the abs code came up and brakes went to floor. I then took it to mechanic and they check code and was abs service and he check abs brake module and was fine he then replaced the vacuum pump and still a hard brake pedal with further investigation he says the master cylinder and brake booster needs to be replaced. In doing some research on the dodge dart there is a recall for 2012-2014 dodge darts brake system which involves the vacuum pump and master cylinder and brake booster. We was able to avoid a accident but what if there are other darts the same year as ours with same issues and aren’t as lucky.

I have a 2013 dodge dart aero 6 speed manual, dual dry clutch, multi air turbo. I purchased vehicle in february 2017. 4 months later I had brought my vehicle into carsense for an oil change. Meanwhile I asked them to check the brakes also due to braking issues and my ebrake was not working properly and had a mind of it's own. It worked when it wanted to, but yet everything is in "great condition" says carsence.mind you that I had just purchased this vehicle in february and it was recently inspected in january 2017. Service dept. Inspected my brakes and gave me the current measurements of existing brake pads left. About june 2018 I was coming up to a stop sign in a 25 MPH side street with light traffic. I had trouble slowing down to a complete stop. When I managed to come to a complete stop I heard a loud bang. Here my driver's side rear rotor was severely smoking and I noticed my rotor was redhot. My rotor snapped completely in half. My shifter would randomly pop out of gear or the clutch would lightly stick, smelling exhaust odor I'm now pushing 62, 000 miles and what do you know. I am coming home into my development. I'm in second gear turning onto my lane and doing maybe 10 MPH well it decides to pop out of gear and accelerates, redlining second gear(I'm assuming it thinks it's in second) and all dashboard lights are flashing steering wheel it locked. Car is now doing 80 MPH in a 15 MPH zone. My brakes are not working at all brake pedal is harder than hard. I have no control of this vehicle!! Engine finally cuts out after I removed the key from the ignition. Comes to a screeching halt. Thank god. It wont start still to this day..oil in turbo and up the hose. Battery plays dead along with my instrument panel and my transmission needs a computer upgrade that's not even available for the 1.4l turbo engine...it needs a TCM, new master cylinder.
