Headlights problems of the 2008 Saturn VUE

I have replaced my headlights 4 times(both sides) and wire harness keeps melting. I have made a complaint before and received no response. I have now purchased the wire harness and I hope this will not burn also. 2. The car jumps when shifting in reverse which indicates the parking pawl. This has been an issue for over a year now and no response returned. 3. Water is leaking into my car. The front and backseat floors are soaked. Looks like the seal around the firewall is not sealing properly. I saw multiple people have the same issue on the 2008-2010 Saturn Vue. Why isn't there a recall? this could cause a major electrical issue.

Both headlight wiring melted. Replaced both side headlights and after 2 years the wire harness melted again the parking pawl gets stuck often. When putting the car in reverse the parking pawl gets stuck. Then it will eventually go into reverse but the car jerks and makes a clunking noise. The light issue I've been dealing with for the last 3 years now. The parking pawl issue has been like this for over a year now.

Driver side headlight went out and then came back on. Then the next day it went out again and never came back on. Took the headlight out and the connectors are melted. . This I think is not good and its going to cost about $150 to fix.

Passenger headlight went out. I attempted to fix it, but a new bulb doesn't resolve the issue. The protective cover over the wiring going to the light is melted and there are noticeable burn marks around the light and light housing.

The contact owns a 2008 Saturn Vue. The contact stated that the brake lights, headlights, and instrumental panel lights shut off several times. Most recently, while driving 55 mph, all of the lights dimmed. When the first failure occurred, the dealer replaced the computer body sensor. After the last failure, the dealer replaced the instrumental gauge cluster and the powertrain control module. The contact has not driven the vehicle since it was repaired. The manufacturer informed the contact that they were unable to exchange the vehicle. The current mileage was 3,719 and failure mileage was 2,070. Updated 04/02/08. The fuel pump was replaced, because the vehicle would not start.
