2022 Ford Bronco Sport: shudder or vibration when accelerating

Filed Nov 3, 2026 · Brakes · MT

While driving, an severe and persistent rear brake resonance defect occurs during braking operations. The defect manifests as high-frequency vibration, loud grinding, and low-speed brake shudder/chatter from the rear braking system, impacting vehicle control and braking predictability under normal driving conditions. The affected component is the complete rear brake assembly, which is currently installed on the vehicle and available for inspection upon request. Safety is compromised due to diminished braking feel, driver distraction, severe auditory and tactile resonance during deceleration, and unpredictable pedal performance during low-speed maneuvers and stopping intervals. The defect has been repeatedly reproduced and formally confirmed by an authorized dealership service center over multiple repair attempts. Servicing included the execution of Technical Service Bulletin TSB 25-2438, which failed to remedy the issue. The issue was formally escalated to and evaluated by the vehicle manufacturer. The manufacturer’s Global Technical Assistance Center (GTAC) evaluated the vehicle and documented in writing that no further technical or engineering procedure exists to resolve or cure the recurring rear brake resonance. Symptoms first appeared during normal operation at approximately 17,000 miles, presenting as severe rear brake grinding and resonance without prior dashboard warning lamps or system error messages. The hardware defect remains active and unrectified.

The rear drive unit (RDU) deteriorated at 78k miles. I began to notice a shudder during low-speed turns with high steering angle. Upon inspection, metallic flakes were discovered in the RDU’s fluid, apparently indicating mechanical degradation of the internal clutch packs. Two separate Ford dealerships recommended complete RDU assembly replacement at a significant expense. I am concerned that an important drivetrain component could deteriorate this quickly, from normal driving use. I believe this could result in wheel drag/lockup or seizure while operating the vehicle. I have not experienced it yet and I’m not sure whether a total mechanical failure would cause it either. Ford has numerous technical service bulletins on this issue, so it is known to them (TSB 26-2328). I am currently waiting for a dealership to receive parts so that the RDU may be replaced.

The vehicle is experiencing powertrain performance issues, including a persistent stutter, vehicle shuddering, and erratic RPM jumping while driving at 45-55 mph. These symptoms began immediately following the latest software flash in January 2026 and have progressively gotten worse. An Independent mechanic and a transmission specialist have inspected the vehicle and are unable to resolve the issue because no diagnostic trouble codes are being generated. There is a safety and engineering concern that the continuous reprogramming of the PCM & BCM has altered the vehicle’s operations outside of its initial factory design parameters. The vehicle has suffered an immediate drop in performance and fuel economy. In June 2026, I received another notification about Recall 25S76, not being completed yet by Sam Leman Ford. After several attempts to reach someone, I called an authorized secondary Ford dealership, Heller in Bloomington, who pulled the VIN data and stated they could not verify if the 25S76 recall was properly completed by the original servicing dealer. It seems as if there is a tracking failure on the manufacturer's side. While she stated there were notes by a service tech for mobile repair, the fact that I got another notification about the same recall’s intermediate repair not being completed, that signified to her it may not have been. Heller Ford stated the only way to know, is to attempt a 4th PCM reprogramming. If the manufacturer rejects the warranty reimbursement, the cost of the diagnostic labor hours will be billed to me. Consumers should not be held financially responsible for verifying faulty manufacturer documentation, nor should software patches be used as a substitute for replacing a physically defective, fire-prone component. By allowing the manufacturer to alter the vehicle's electrical and powertrain architecture rather than mandating a hardware replacement, consumers are left driving vehicles with degraded performance and an active hazards.

After coming to a complete stop at a stop light, my engine began to shudder and then stalled out. I received a message on the dashboard to shift to P and restart my engine. After shifting to P I was able to start my engine. When shifting to R my engine acted normally. When shifting to N my engine acted normally. When shifting to D my engine began to shudder and stalled a second time. After waiting for a light cycle I attempted to restart my engine and shift to drive a third time and my engine stalled when shifting to D. I required a tow truck to take my vehicle to my dealership. While waiting on the tow truck I had to shift the car to neutral and push the car onto the shoulder from the center lane where my car stopped working. My dealership was able to replicate the issue and informed me my torque converter had failed.

Along with the current unable to be fixed PCM recall, the customer service satisfaction program regarding the drivers side buckle replacement and the replacement of high-pressure fuel injectors that I was told they will only replace if there is an issue because it is not considered a recall. I have had multiple other recalls that were done and several issues that weren't related to recalls. In the first year the bushings were replaced to ease the loud noise when backing up. At 36,0000 miles I had no heat. The water pump failed and was fixed under powertrain warranty. At 41000 miles (just over warranty) the AC stopped working. The condenser failed and was my responsibility to pay. Ford did work out a deal with me on that repair due to all of the other issues I had previously. Currently, my drivers side back seatbelt does not work, the car shudders when driving and recently my forward collision indicator goes off for no reason. I have not reached out to have these items checked yet as I have spent far to much time dealing with Ford. I bought this car to feel safe and confident on the road and I have never felt that. The lack of compassion from Ford for all the money wasted in missed work and repairs because they cannot produce a quality vehicle is abhorrent.
