Whole car vibration during acceleration
The vehicle shakes or vibrates throughout the entire car when accelerating. This typically points to a drivetrain or engine-related issue rather than a simple wheel balance problem, as the vibration is load-dependent.
Diagnosis Details
Possible Causes
Worn or failing CV (constant velocity) axle shafts – damaged inner or outer joints cause vibration under acceleration.
Engine or transmission mount failure – broken or deteriorated mounts allow excessive movement, causing vibration when torque is applied.
Driveshaft or propeller shaft imbalance or worn universal joints (if applicable) – less common on front-wheel-drive Elantra but possible on AWD models.
