Power trunk pops open intermittently while driving.
I bought the car mostly on its styling... as I grew up riding in my Dad's 1965 Impala... The 2005 has some of the classic Impala styling cues (though should have 6 taillights, not 4 to be true to Impala Heritage. I enjoy the car, Its black, LS, with the appearance package... rear spoiler, body colored taillight panel, lower body cladding, leather interior with compass, temp, and trip computer, which I like... The car has plenty of pep from its 200 HP 3.8 liter V6...The only concern I have is the design of the fuel filter connections... The front connection is traditional, held on with a nut... the rear connection is via a black flexible line leading to the fuel tank with a small gray plastic retaining clip that you have to push up with a screwdriver to release in order to pop the rear line loose... If you are a do-it-yourselfer, and break that clip, it is difficult to get... GM only lists the line itself as a replaceable part, which means dropping the fuel tank to replace the line from the tank to the filter...luckily, a mechanic had some clips laying around.. it took me 10 seconds to snap the new one in... Aside from all this, I am very satisfied with the car, I like its looks and performance and economy, which approaches 28-29 MPG on long trips.
Update and correction by the original poster regarding the original posting... typo error on title of posting... The car is a 2005, NOT 2006 model...
We used to have a Chevy Impala; it worked great.
