2018 CHEVROLET IMPALA Complaints and Recall Information
The 2018 CHEVROLET IMPALA has 5 complaints and 1 recall filed with NHTSA. Owners most frequently report issues with the steering system, braking system, and air bag deployment. Several complaints involve the vehicle failing to respond correctly to driver inputs without warning lights illuminated.
Common Issues
- Steering failure. The power steering electrical motor and steering gear become inoperable without any warning lights, preventing wheel straightening while stationary.
- Brake malfunction. Excessive force is required to depress the brake pedal, causing the vehicle to roll backward or forward unexpectedly. The ABS module often requires replacement due to low voltage and communication errors.
- Air bag deployment. The driver’s side air bag deployed unexpectedly while the vehicle was parked. The air bag warning light had previously illuminated during driving.
The Impala has one recall affecting the braking system. This recall addresses a potential safety defect related to the rear brake caliper pistons that could reduce brake performance. The repair involves bleeding the brake system at no charge to owners.
Recalls
- Service brakes, hydraulic. NHTSA recall 18V576000 affects 210,628 vehicles including the 2018 Impala. The rear brake caliper pistons may have an insufficient coating, causing gas pockets and reducing rear brake performance. Reduced braking increases the risk of a crash. GM will notify owners and perform a free brake system bleed. The recall began October 11, 2018.
Owners who face repeated repairs or have unresolved safety defects might have rights under their state’s lemon law. Consulting an attorney familiar with these matters can help clarify available options.
