general problems of the 2007 Infiniti G35

We purchased this 2021 Chevrolet trailblazer rs new from the dealership and we noticed on the second day of owership that the brakes were "squealing". The dealership initially inspected the vehicle ASAP and without having to go through the service department. However, the problem not only continued, it persists to this day. Additionally, we just purchased a used 2023 Chevrolet trailblazer rs (with under 10,000 miles) and are experiencing the identical issues with the brakes squealing.

When I press brake pedal down the brake starts to slow the car, but all of the sudden the brake is completely to the floor. The car just keeps going. Brakes completely gone. I had to use the e brake to stop the car from slamming into another car in an intersection. I was able to pull the car off and on to a side road where I called aaa for a tow. That unfortunately was not the first time this has happened. The first was in a drive thru. I went to stop at the window and literally just kept rolling like I was not even pressing the brake. I started to panic and frantically pumping brake when finally I somehow had brakes again and the car came to a sudden stop. Very scary. I reported this issue to Infiniti and the lady on the chat live said sorry there's nothing we can do for you. I have read blogs and blogs of people having the same issue I don't get how this is legal and not recalled. I had my child with me the day I used the e brake he was so scared he didn't want to ride in the car again.

The contact owns a 2007 Infiniti G35. The contact stated that the air conditioner did not operate as intended. Only cold air emitted and could not be turned off. In addition, the vehicle brakes independently applied and the vehicle experienced a loss of power. The dealer was not contacted. The manufacturer was notified and did not assist. The failure mileage was 126,000.

This safety concern is in regards to the brakes every time I accelerate on the brakes from speed there is a vibration causing the vehicle to jerk.

Two different incidents - I was in two minor low speed incidents. I believe at the time of the second the brake rod got bent (which is currently speculation and the insurance is investigating) from the first accident. After the first my accelerator would not function on some left hand turns. I got in the second accident because of the inability to "brake harder" and I was amazed I couldn't stop in the distance provided, and this braking scenario and outcome is repeatable. If I brake hard -- harder -- full stop. By the time I do a full stop my braking power is diminished and in my accident I was unable to stop in a "normal" distance. Furthermore, after this second accident at < 20 mph. I have intermittent accelerator failure in all driving scenarios. I could be driving and it just cuts out. No error lights in either of these scenarios. No check engine, no slip, no abs, warnings. I previously tried to bring it up to corporate Nissan and they said I had to contact the local dealership. Both dealerships I tried pawned me off to parts department, which the guy was confused as to why I am asking him about potential short falls. They wanted over $1,000 each issue to investigate. Meanwhile as I now find my car unsafe to drive for lack of accelerating and braking abilities, and the insurance company is investigating. Two accidents in 6 months, and at least the latter I think could be due to a potential faulty part - as every mechanic I have reached out to said if it is the brake rod, and in the accidents I had, it should not have bent (if that ends up being the root cause). Let alone the accelerator issues.

Parking break does not hold car when fully engaged, even on a very slight hill. This has always been the case, even when the car was new.
