When driving in my normal seated position I find that transitioning from the accelerator pedal to the brake pedal can be uncomfortable at the least to almost dangerous.the left edge of the right foot almost always gets caught behind the right edge of the brake pedal.it would appear to me that the brake pedal is too close to the throttle pedal. Has this issue ever come up before? I've talked to others who have driven these models and the problem has been noticed.if the right foot is placed more to the right (more in line with the accelerator pedal|) it is not a problem.but isn't a normal position for me as I would assume for other drivers.I'm sure that shoe size or style would make a difference. But in a confined are like these cars have (the console seems wider to allow for the transmission position) that an allowance for more room between pedals should have been made. Dave

On 6 June, 2013 while driving on M59 in Michigan and applying the brakes, my knee made contact with the remote fob, causing the ignition key to move from the "on" position to "accessory" mode. The engine stopped running and I had to steer and brake the vehicle without power assist to the shoulder of the road. I put the vehicle in park and restarted without incident. The same situation occurred in January 2014 while driving on I-75 to Florida. In both cases I informed my dealer (lafontaine Cadillac in highland, Michigan). The response was that they had not received any similar complaints and they could do nothing about it. I informed GM of the issue and they arranged to have the vehicle examined today, 1 April, 2014. I just received a call from the dealership informing me that the ignition switch met specifications. Whether or not it did (and to which specification) is academic. This is a safety issue! while I was able to manhandle the steering and braking, I doubt that my wife would be able to.

Since purchasing this certified pre-owned vehicle, I have noticed that the car's engine has an intermittent tendency to suddenly rev or idle very high while my foot is on the brake and I am in the process of slowing down, stopping, or pulling into a parking apace. The car lurches forward and is only controlled during those times by applying a great deal of pressure on the brake until the idle returns to normal and the car stops trying to lurch forward. I have taken the car back to the service dept. Of the dealership each time (at least five times or more), but the problem had not been duplicated until the shop foreman drove it one day and was able to experience the problem. He replaced the throttle body, but the problem continues. I complained to GM and to the Virginia better business bureau because I didn't feel enough was being done to resolve the problem. Initially, GM ignored me and offered no response. When the BBB became involved, I did get a GM response. The BBB suggested the installation of a vehicle data recorder ("black box") to help in the detection of the problem. I recorded three separate incidents on the recorder. Still, the dealership attempted to point the finger of fault at me, stating that I must be driving with my feet on both pedals at the same time! I do not practice such driving habits and told the BBB so. Since the vehicle showed no further problems for a couple of days, the BBB suggested I close the file and maybe reopen later -- if my mileage qualifies to have the case reopened. I sense the BBB's resignation to support GM and the dealer, despite the fact that I have all of the necessary documentation to support my claims. I have become extremely frustrated and very nervous about this potentially dangerous defect, and nothing is being done about it. I am hoping that you can help resolve this.

The contact owns a 2010 Cadillac Cts. The contact backed out of the driveway, placed the vehicle in drive, when it suddenly accelerated independently. The contact depressed the brake pedal continuously until the vehicle came to a stop. The vehicle was taken to the dealer for diagnostic testing where the technician advised the contact that the power brake booster auxiliary pump would have to be replaced. The vehicle was repaired. Immediately after the repair, the failure recurred. The technicians inspected the vehicle and advised the contact that a fuse to the auxiliary vacuum pump failed and would have to be replaced. The vehicle was repaired. The approximate failure mileage was 21,877. Updated 9/17/12 updated 09/21/2012
