Other Fuel System Problems of Jaguar XJ

The engine has issues where there is a jerk while accelerating at times. I was told of a misfire issue that Jaguars have and have not been corrected. I was driving my 2012 Jaguar Xj on the interstate when it started slowing down. The engine light than appears on the dash and it starts to jerk as I try to speed up to get off the highway it goes from 60mph to 45mph. I take my foot off the gas and press the gas again for the car to jerk and accelerate slowly back up to 60mph. Not only was I almost hit from behind but almost crashed trying to get over and off the road for my safety and others. I was told by a mechanic the car needed a new gas treatment, fuel cap, and tune up all this money paid and no results. The 2012 Jaguar Xj still stalls when accelerating. The buttons are melted into a gummy substance and a barely used sunroof wont close has a loud noise when button is touched to try and close it. Worse experience ever with my 1st and last 2012 Jaguar Xj.

While stopped in the road waiting for another car. With foot on brake, the car suddenly goes full throttle. Driver has both feet applied on the brake and the car still moves forward burning rubber, and then after a few seconds it goes back to idle. The car does this once or twice a year, the last time doing damage to a car in front of it. This is the fifth time this has happened. The car is idling normally with the right foot on the brake and it will just go full throttle all by itself. It has happened enough that we know we do not have both the brake and the gas pedal depressed. From doing online research I believe Jaguar and Toyota / Lexus used the same system for controlling acceleration. I replaced the throttle body after the fender bender, it evidently did not help.

While being stopped at a stop sign with foot on brake the car suddenly accelerates. This is the 5th time this has happened, one time resulting in an accident. I have called Jaguar and they blame the driver. I replaced the throttle which contained the same tps sensor that has plagued toyotas. I am going to replace the pedal sensor and if that doesn't work I guess I will sell the car. Each time this happens the car is stopped with the right foot on the brake. The accident was at a school waiting in a line of stopped vehicles waiting to pickup students.
