Hello Forum. The title of the post only states a few of the issues, but I wanted some help possibly identifying what's normal and what's not in this car. I have a Black 2018 Cruze LT Sedan 1.4L Automatic with just under 2,000 miles on it. To start, i'd like to note that it needed a brand new front right axle and wheel hub bearing at 600 MILES, so I don't know whether the following issues are real of if they're a result of the paranoia that's risen from the initial repairs needed.
1. The gas pedal vibrates as I accelerate and every bump in the road can be felt as my foot rests on it when i'm coasting with cruise control on.
2. The brake pedal has a subtle, uneven "clunk" I can feel when braking at lower speeds, as opposed to being totally smooth.
3. The whole car shakes lightly, or rumbles infrequently when idling at low RPM's. It's not violent or anything but it's noticeable and i'm fairly certain it didn't do it when I first got the thing.
4. When coming to a stop from speeds upwards of 45 mph, it downshifts fairly heavily, but I think that's just how the automatic transmission is in this particular car.
5. When I initially start it up, the engine itself vibrates like crazy in it's setting at over 1000 RPM's, then slows down to about 750.
The first time I had it in the dealership they had it for a week and returned it to me saying nothing was wrong. The second time I had it in they had it for 4 hours and chalked it up to the fact that I "don't drive it enough and the condensation that can form in the intake doesn't get burned off" and that there was still nothing wrong with it. Given that the engine takes 10-12 minutes to heat up and it only takes me 8 minutes to get to work and it's all city driving and no expressway I can kind of see what they mean, but that cant be it.
Sorry for the wall of text, but i'm driving four hours up north in a few weeks and my car is making me nervous about it. The dealership can't pinpoint anything and I don't know where else to turn.
