1800 miles, no mods, not abused.

Mild 1st gear pull (without any loss of traction that I could tell), didn't even approach redline.

LOUD POP! (can't tell if exhaust vs engine vs electrical), engine loses power, gas pedal does not respond, engine makes sputtering/bubbering noises (misfiring?).
Multiple dash lights "Service AdvanceTrac" "Service soon" (with wrench), Pre-collision assist not available.
Rolled the car into a nearby park.
No issues visible under hood.



Restarted 1-2 minutes later and everything seemed normal, no dash lights.

FORScan shows:
ABS U0100:87-28
APIM B108E:87-08

Sound similar to TJ HUNT’s GT, ended being cracked piston(s). So idk maybe take it in to check. Popping and burble is normal but with power loss is not normal.

an advisor at my dealer just had to replace an engine in a 2024 GT with 11000 miles. cracked cylinder 7 piston, bent valves with the actual valve heads sideways in the head or missing. customer just said it "died in flight", likely not explaining the actual events due to the potential for the engine not being covered by warranty
