I've owned my 2014 Impala LS for a couple of months now and like almost every aspect of the car very much but I'd like GM to address one important safety concern.

The standard halogen projector headlights on the Impala rely on a single light source with a shutter to control switching between high beam and low beam -- a method more normally reserved for HID installations. The problem with the system is not so much the intensity of the light produced (which is not great), but its beam distribution. On both high and low beams very little light is dispersed to the front sides of the vehicle and on high beam the long distance component of the light is very narrow -- approaching a pencil like distribution with limited scatter to the sides. This means that sharp right turns are very tricky (you cannot see the side of the road to the right as you make the turn) and any pedestrians to the side of the vehicle at an intersection are invisible. The narrow beam distribution is also far from ideal for winding country road driving at night. This is not the case with our 2003 Malibu, for instance, which has separate reflector main and low beams, and throws quite a bit of light to the sides. It was also less of a problem with the 2013 Malibu I drove recently, which has projector low beams and reflector high beams.

A fix may be as simple as redesigning the projector lens to throw more light to the sides of the vehicle or installing supplemental cornering lights, but ideally the system should have a stronger light source too. The status quo is not satisfactory and potentially unsafe. With so much riding on an otherwise excellent and modern vehicle, I hope GM is responsive in addressing this issue with a design change and a speedy recall to fix the existing fleet.

The headlights on this model do not provide enough coverage for night driving. The beam does not spread to see the side of the roads. I live in a rural area and one day 5 deer were standing in the road. I almost hit them because the headlight beam does not go out far enough to give you ample time to react. I took the car to the dealership and they claim it meets specs. I told the manager to drive the car at night without street lights and reflective road paint and see how well the lights work. I have complained to Chevrolet regarding this issue and their response is they function properly.

The 2014/2015 Chevy Impala's have a problem with their headlight beam. They do not fan out to see left or right. When turning onto a dark street or road at night, no matter if on high or low beam only has a pin point beam straight ahead. If you look out your side window to make a turn onto a unlit road or street, it is totally black. If there would be a person at the corner, you could hit them. I have made a left turn to a unlit road and almost went in the woods just past the road. Luckily no accident, but very difficult to see when turning at night.

They should come up with a recall to fix this problem. Great car except for the lighting. I have found other reports for the same problem & they are filed with the NHTSA. I have never had a car that didn't show some light to the sides of the road that help when making turns. I had the dealer check the lights & they said they are normal that there is no adjustment for right. & left only, up & down. This could turn into a major law suit for GM if some one gets injured because of this manufacture flaw . Thank you please fix.

Update from Oct 1, 2015: I changed the halogen lights to HID lights they are brighter but still do not fan to the sides of the car, this seems like a bad design for the headlight assembly on the new impala's
