About 2 years ago, I paid close to $4,000 to repair the coolant system in my Jaguar Xj. I now have the same issue.

I have a 2011 Jaguar Xjl supercharged with 65,000 miles that has a knocking noise and is in restricted performance mode. The timing chain and tensioner were replaced by a shop, but that did not fix the issue and I’ve been told there is internal engine damage. The internal engine damage has not been identified. The car itself is in excellent shape, but I don’t know how to proceed to address the internal engine damage as the shop is recommending replacing the engine with a used engine from the salvage yard, but that concerns me as I don’t know the history of the engine from the salvage yard. I've done some research and apparently this is a common issue. Does anyone have any insight on how to proceed with an arizona recall as this is not normal? any recommendations will be greatly appreciated. Thank you.

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.

A seris of issues plaque this model. Changed throttle body twice but car keep showing stability control not available, throttle body actuation issues with p2119,p2118 codes among several others. Car shakes and shuts down in the middle of driving. At idle, the car rev meter goes up and down and then shuts off. I have taken this car to galpin Jaguar over 5 times with the same problem and each time the problem remains the same. I have since taken it to another mechanic two more times paid thousands of dollars to replace parts and still the problem exists. This has been going on for literally months. Everything I have been told, I got it fixed yet, the problem still exist. These set of issues happens at idle, when driving on freeways, and city streets. I have called aaa so often I have no more. Another issue- the car will stuck in drive gear and stop and shuts off. I have even replaced emc computer. The issue started last year March but stopped when I changed throttle body and lasted about 6 months, then started acting around September again and its at the mechanic now and they cant find the issue still.

Car stopped working in the freeway warranty detected,after I had to pay $1200 to tear engine, that a hose behind engine was disconnected which caused overheating of engine. No sensor warning alerts shown. Car has 64k mileage sold with 41k. Warranty didn't cover dealer will start charging me for storage. Car with dealer since 11/20 warranty just checked on March 2021.

I was calmly driving slower than 35 mph on a city street when the car suddenly slowed down and stopped responding to the accelerator pedal. When I tried to step on the gas I heard a big explosion-like sound. Then all of a sudden the car accelerated to what seems like over 100 mph and the breaks did not work despite me pressing the breaks several times. I shot into 3 cars ahead of me that were at the red light. The other cars received substantial damage; I saw that others were injured. My car was completely damaged/crushed in the front and a fire had broken out. The airbags had deployed and I was pretty much pinned to the seat. I had bought the car from the dealer brand new and had it regularly serviced and maintained. I was the only driver and it had only 30000 miles over 3 yrs.

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.

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.

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.

Braking on street to turn into house drive when the car suddenly increased speed and before I could get it in neutral I crashed into a house stone wall. Pictures on request.

While at a stop light, engine revved up and the car started rolling forward. I had to brake hard to stop it. This happened about 3 more times over the next 2 months. One time the engine raced very high and I had to put it in neutral to avoid crashing. At 5000 miles I took it to the dealer who said they could find no diagnoses from the auto computer and could not replicate the problem. They claimed to have no knowledge how to fix, but now I see a number of reports on the internet about Jaguar rapid and unexplained acceleration problems. I feel Jaguar is not being honest about this problem -- and it is dangerous condition.

Jaguar 2005 Xj vdp has experienced many episodes of unintended acceleration during braking to a stop. As brake is applied, the engine throttles up and car cannot be completely stopped. When car is quickly shifted to neutral and braking maintained, the engine revs over 10,000 rpm and the ignition must be cut in order to stop the episode. On one occasion the car could not be stopped at a busy intersection, forcing an urgent lane change and right hand turn to avoid accident. Jaguar has "reprogrammed computer" on car with a reduction in frequency of the episodes for about 6 months, however problem now occurs several times/month.
