In very cold weather, -10c for example, if I drive the car through a car wash, and park the car outside, then apply the parking brake, they freeze in the applied position. The dealer says it's a natural thing, but I had many cars before that went through the same routine and never had a parking brake freeze. I tend to believe the dealer knows of the flaw, can do nothing about it, and has only cheap excuses to manage the problem.
Ahhh! The all too known "control arm bushing" problem. Loud clanging noises from the front suspension when crossing bumps, or driving through even slight rough road. The dealer replaces the control arm bushing, this takes care of the problem initially, then it starts coming back after about 10000 km. Certainly a defect in the suspension, as pointed out in many other reviews on the vehicle.
When I hit the brake at high speed, the front end vibrates heavily. I took it into the dealership, they claimed that the brakes (all four of them) needed replacing. Very expensive work. Replacing the brakes did not resolve the problem. While the car was in the dealership for the brake work, they damaged it, and needed to keep it longer to fix the damage. I rented another G5 for the period, guess what... same problem with the rental G5, high speed braking vibration.
The car pulls to the left at high speed. I have to put effort into keeping the car straight. I tried all lanes on the highway, in all cases, the car pulls left. The dealer checked the alignment, they claim its all within spec. Tire pressures and tire quality are good. They test drive the car, they say it's OK, but it's not. Dealers seem to have to make a lot of excuses for this poor product.
After three years, I had to get the tires serviced. Apparently they lost their bond with the rim and were all leaking slowly.
Recalls: Injectors replaced, power steering control motor replaced.
