2022 JEEP CHEROKEE Fuelpropulsion System Problems

The vehicle stalled at a busy intersection during heavy traffic hours. No watnings or signs that could've prevented the incident were indicated by the vehicle. 911 was called in to aid in the traffic incident. Call [XXX] from Laredo Police department. Vehicle was pushed by the Police Officer and myself to a near by parking lot where the vehicle was towed to the dealership. Dealership experts noted leaks on some parts of the engine due to britle gaskets and the major mechanical failure was due to a faulty fuel pump.

Your website has some trouble & won't accept my jpg files. First time to see this. I use cruise control all the time on 3 vehicles I own. But, this JEEP has a strange problem that is not safe. Almost all vehicles I have driven with cruise controls will exceed set speed by 1~3mph while going down a steep hill. But my JEEP will exceed by 5~7mph on steep hills. I have turned off cruise control when it didn't control speed and drove manually for a while, then used cruise control again. If I set at 70mph, often speed will increase to 75~77mph going downhill; then brakes will engage strongly (hard braking) and JEEP will quickly go below 70 mph. JEEP will brake hard, go to or below 70mph then speed up some then brake hard again! Two-three times I had 18 wheelers behind me going down steep hill when...

In late November 2023 I noticed my fuel economy dropping a lot, from 27-29mpg to 22-24mpg. And, soon tailpipes were accumulating a lot of soot in tailpipes and soot was coming out of end of muffler. I took to JEEP dealer in Palestine, TX. See invoice uploaded. Service advisor couldn't find any bad codes. He wrote some guesses as to source/cause of problem & suggested using more expensive, higher grade of gasoline. He said to try some catalytic converter cleaner, also. Seems, he thinks the braking system may be causing soot troubles. This soot problem will cause injector, spark plug, catalytic converter expenses in future! And, I have to spend much more for gasoline? I think main control module is defective and is missing computer code to properly detect this problem or is intentionally designed to ignore the cause of the excessive soot problem. It is not normal to have...
