\the accelerator pedal and brake pedal are separated by 1-1/4 inches. At rest, the brake pedal is about 1/2 inch higher than the accelerator pedal. When depressed, the brake pedal is 1 inch lower. It is very easy to move your right foot from the accelerator to depress the brakes and not be far enough over to avoid also depressing the accelerator at the same time. There is 4 inches of space between the accelerator pedal and side of the car body on the right side. This is plenty of room to relocate the accelerator pedal to the right, perhaps so that there is the width of a man's shoe sole between the two pedals.

I felt a shutter time to time at start up, and would feel like the wheel would grip on hard turns backing up, was like this for a couple of days. Filled tank & drove out of town, at destination noticed leakage under car, under drive seat. Thought it might be condensation. Vehicle sat for 2 hrs., no leakage visible at start up, after starting vehicle notice leakage began again and this time at a larger volume, could smell the fuel. Called dealership they picked it up on tow truck, when back end was lifted, a significant amount poured out from under car. Was told that the fuel hose/fuel pump has the cause due to rubbing. First 3 weeks was told part was on backorder, then that it was going to become a recall and that the part needed to be redesigned and that there was no immediate time frame for vehicle return. I have been driving a dealership loaner for 2 months now. Dealership asked if they can "craft" a patch to get my vehicle out of the shop. I denied this, considering I don't know what the legalities will be. Very disappointed in Chevy, this is my 3rd Suburban/Tahoe and I'm considering filing lemon law.

Suburban 4WD 8-cyl

  • 3,500 miles
The vehicle had approximately 3500 miles when returned to dealership. The primary issue was "running rough." The vehicle was in the repair shop over five weeks. In three incidents picked up the vehicle when it was supposedly fine. Within minutes the cecile stalled and starting to shutter. Warning indicators include engine and transmission system, emission system, stabilitrack stability control system, and antilock braking system. Vehicle unsafe to drive. The 2015 Suburban was newly designed. Repair bulletins were issued. Vehicle recently picked up and still "runs rough." The vehicle handles differently as it shifts from V4 to V8 (fuel economy design) when slowing. This makes the vehicle handling inconsistent depending what mode it is operating and can be unsafe. Other potential safety issues when raining, the rear camera (backup) is not functional. Also, when starting in reverse, there is an extended period the "computer is loading" and their is no input although your backing up. In essence, the rear backup warning system is not functional.

Since purchasing this vehicle in July of 2014 it has been back at the dealer several times for the tighten gas cap light & the check engine light. Even if gas hasn't been put into the car for several days the light just comes on and soon after the check engine light comes.
