The 2007 Impala steering system shows chronic defects across multiple components. The intermediate steering shaft develops clunking or clicking noises during turns—sometimes progressing to complete steering wheel lock-up where the wheel becomes immobile for seconds at a time. Some owners report this happens before 36,000 miles; one dealership technician told an owner most shafts he's seen break before that mileage. GM has not recalled this part despite documented awareness.
Power steering problems are equally troublesome. Pumps lose effectiveness, lines leak (sometimes due to road salt corrosion under plastic sheathing), and rack-and-pinion assemblies fail repeatedly even after replacement. Owners describe having to refill power steering fluid daily in severe cases. One owner paid $830 just for rack replacement.
The rear suspension spindle rods—which GM acknowledged are defective—cause rapid inside-edge tire wear. Several owners burned through multiple tire sets in months and had wheels fall out of alignment within days despite professional service. GM recalled only police vehicles for this known defect, leaving civilian owners exposed.
Steering wheel seizure during driving is documented in multiple complaints, including one police officer who experienced four lock-ups. Dealers cannot diagnose the cause. Additionally, some vehicles experience false ABS engagement during low-speed turns and recurring traction control activation that expensive repairs (transmission, bearings, brakes) don't resolve.
