Nothing has changed

2007 Chevrolet Impala LT 4dr Sedan (3.9L 6cyl 4A)
I have a 00 with 3.5 liter 240,000 miles on it. Father has 07 with 3.9 liter. These Impalas may have changed body design and engines but still have the same problems. The VERY common probs with these cars are Transmission failure Intake gasket manifold failure (most common) Intermediate steering shaft failure Cars with pass lock have problems consistently. Headlight switches have failures fairly often. Water pump will start leaking between 36k and 55k. Radiators will split at the side tanks around 125k Brake rotors tend to warp prematurely. Tire pressure monitoring system is horribly troublesome. New designs, new engines, same ole problems
Good ride, comfortable. Internals of the GM v-6s last a very long time. MPG on my quarter million mile 00 Impala is still 22/33 with synthetic oil.
Make a transmission that actually works and lasts. FIX THE INTAKE GASKET PROBLEM!!!!!! Do something about the crappy made in Mexico water pumps. Make tire pressure monitor that works or just do away with it.
