Intermittent instability issue for over a year, worsened after front right wheel hub replacement.
Symptoms:
At highway speeds (worse 55+ mph), vehicle becomes unstable.
Whole car feels like bouncing, rumble-strip vibration, and side-to-side instability.
Other drivers visibly react / slow down when it happens.
Feels chaotic and unpredictable, not rhythmic.
Issue sometimes resets and vehicle drives normally again.
During episodes:
Engine RPM changes without changing throttle input.
Gas pedal response feels reduced or altered.
Brake pedal sometimes requires different pressure.
Occasionally Stabilitrak / traction control light appears.
TPMS light blinks at startup then stays solid (both front sensors failed weeks apart).
Sometimes burning smell after episodes.
Work already performed:
Both front struts replaced.
Both front lower control arms replaced.
Alignment performed.
Front right wheel hub replaced.
Tires balanced multiple times.
Dealer diagnostic performed ($250) – no resolution.
Suspension work completed after dealer visit.
Notes:
Issue worsened after hub replacement.
Front right tire shows uneven wear and surface pitting.
No consistent ABS codes stored.
Problem is intermittent and difficult to reproduce during short test drives.
