The 2004 Chevrolet Impala has 3 recalls, the most serious being an engine oil leak that drips onto the hot exhaust manifold and can start an engine fire.
The ignition system also has a recall worth attention: if weight on the key ring causes the ignition to slip out of the run position while driving, the airbags may not deploy in a crash. Until the repair is done, removing everything from the key ring except the ignition key reduces the risk.
