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.

What 2012 Jaguar XJ owners say
Most recent owner complaints, unedited.
The contact owns a 2012 Jaguar XJ. The contact stated that when the vehicle was started, the vehicle stalled. The contact performed a diagnostic himself and found that the fuel pump wires were melted and caused the wires to fuse together and caused a short circuit. The contact replaced the fuel pump. The vehicle was repaired. The manufacturer was not contacted. The failure mileage was 67,894.
I have spent thousands of dollars repairing the suede lining on the interior of the car. Now, I can't even find anyone that will touch it! The wood grain has faded and the vehicle is garage kept. The horrible buttons were made of a material that literally became gummy. I spent hundreds having them replaced. Sunroof had to be replaced/motor more than once, the clear coat on the back panel of the roof has peeled. I have had other cars with almost 200,000 miles that had perfect paint when traded. The paint on this vehicle is terrible. This is only to name a few of the issues. I could have purchased a new vehicle for what I have spent on this car. I love this vehicle but most likely will never purchase another jaguar.
I took my car in for an alignment. After checking under the car, the mechanics realized that the coolant tubing was made of plastic and broke. They stated that if I drove the car, I would be in danger of the car smoking and maybe catching fire. I had to replace the coolant. I was informed the jaguar has changed their engineering of this risk due to the number of complaints and repairs. I also have a 2012 xf and it has the same issue within the same week which is costing me $2200 to replace. This is a serious issue if the coolant issues results is smoking an potential fire of the engine.
Tl* the contact owns a 2012 jaguar xj. On a cold day, the contact noticed that the door latch was frozen and could not be locked without warning. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 44,000.
2012 jaguar xj. Consumer writes in regards to vehicle sunroof malfunction. *smd the consumer stated the electronic shade wouldn't close all the way. It would close crooked, and there was a horrible creaking noise that came anytime, he traveled on an uneven pavement. The dealer adjusted, calibrated and lubricated the sunroof several times.
Applying brakes my foot also hits the gas pedal which makes the car leap forward.
