Electrical system complaints dominate owner reports for the 2010 Impala, with airbags and the powertrain rounding out the most-reported areas. On the electrical side, owners frequently describe warning lights appearing unexpectedly, reduced engine power messages, and traction control cutting out during normal driving. A handful of reports describe in-vehicle fires traced to the dashboard area, though these appear in a smaller number of accounts. Airbag complaints center heavily on the airbag warning light illuminating at startup or during driving, often without any apparent trigger, owners report the light staying on persistently. On the powertrain side, owners describe grinding noises during startup and while underway, sometimes continuing even after the engine is shut off. A recurring pattern in the electrical complaints involves multiple systems going offline together, with the check engine light, reduced power mode, and traction control loss appearing as a cluster of symptoms in the same event.

By System
The 2010 Chevrolet Impala has 3 recalls, the most serious affecting police-package vehicles only, where a front lower control arm can fracture and cause sudden loss of steering control.
The other two recalls affect occupant protection on civilian models. The front seatbelt on the driver's side door edge may not be properly secured at the anchor pretensioner, meaning the belt can fail to hold an occupant in place during a crash. There is also a concern with the passenger seat's presence sensor, where the seat frame can rub against and damage the sensor's wiring. If those wires are cut or worn through, the system stops detecting that a passenger is seated and disables the front passenger airbag entirely, leaving that occupant without airbag protection in a collision.
