Off to the dealer with my repair list.2025 heritage.
slightly over 4k miles on it. Manual trans. Pretty ridiculous.
1. Throttle stops responding after the engine bogs

1. Throttle stops responding after the engine bogs
- This has happened twice while driving. Both times, I was slowing down and accidentally selected 4th instead of 2nd, causing the engine to bog below its normal idle speed.
- I immediately pressed the clutch and shifted into 2nd, then 1st, and pressed the accelerator. There was still no throttle response, and the RPM would not increase.
- Pressing and patiently holding the clutch causes the engine to automatically cycle off and back on. Throttle response returns immediately after that cycle.
- I can reproduce it in a controlled area: while moving slowly at about 10 mph, briefly misshift into 4th and let the engine bog. Then shift immediately into 2nd or 1st, to try and recover, there is no throttle response. Patiently Pressing and holding the clutch causes the engine to cycle off and back on, restoring throttle response.
- There is a rubbery rotational squeak while coasting forward or backward. Braking does not change it. The same noise can be heard when rotating either front wheel while the Bronco is lifted.
- I traced the noise to the front driveshaft CV joint where it connects to the transfer case. Grease is coming out beneath the large CV-boot clamp and has been flung onto the surrounding area. The inside of the boot appears dry.
- The driver-side front shock is wet around the reservoir-to-shock-body connection. The shock on the other side is dry.
- When I started the Bronco at Costco, it displayed Hill Start Assist Warning, Antilock Brake Fault, Electronic Parking Brake fault, and Pre-Collision Assist Not Available.
- The warnings remained after restarting the vehicle several times. They went away after approximately five minutes of driving.
- The warnings are saved in FordPass.
