NHTSA's VIN data lists these trims for the 2015 Impala. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 300 complaints with NHTSA about the 2015 Impala. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 3 recall campaigns for the 2015 Impala over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Impala vehicles manufactured April 15, 2013, to June 19, 2015, equipped with front vented-heated passenger seats. Accordingly, the Automatic Occupant Sensing (AOS) system may fail to suppress the front passenger air bag if a child seat is in the front passenger seat. These vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 208, "Occupant Crash Protection."
Risk: If the front passenger air bag deploys with a child seat in the front passenger seat, it increases the risk of injury to the child.
Remedy: GM will notify owners, and dealers will correct the calibration-learning error by preconditioning the empty seat, and also resetting the ECU to a seat zero-value, free of charge. The recall began on August 25, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 15400.
General Motors LLC (GM) is recalling certain model year 2013-2015 Cadillac XTS vehicles manufactured February 14, 2012, to August 22, 2014, and 2014-2015 Chevrolet Impala vehicles manufactured November 5, 2012, to September 2, 2014. In the affected vehicles, the electronic parking brake piston actuation arm may not fully retract causing the brake pads to stay partially engaged.
Risk: Brake pads that remain partially engaged with the rotors may cause excessive brake heat that may result in a fire.
Remedy: GM will notify owners, and dealers will update the electronic parking brake software, free of charge. The recall began on October 28, 2014. Owners may contact Chevrolet customer service at 1-800-222-1020, or Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14471.
General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Impala vehicles manufactured May 7, 2014, to July 28, 2014. In the event of an accident, the center storage console may not stay latched. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 201, "Occupant Protection In Interior Impact."
Risk: The storage compartment door may not remain closed in the event of a crash, increasing the risk of occupant injury.
Remedy: Parts to remedy this condition are not currently available. GM will send owners an interim notification in early October 2014, and will send a second letter when parts are available. At that time dealers will inspect, and if necessary, replace the console storage compartment door inertia latch, free of charge. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 14476.
