2020 JEEP Gladiator

My jeep has 140,000 mile engine oil has been changed on time every time. And the engine has cylinders that are missing and it's using antifreeze and riddles like a diesel from time to time. I looked it up and it seems to be a common problem with these engine and there has not been a recall for this. But funny thing is they make a repair kit for this issue. Why has this not been recalled yet it's on all the jeep forms. Even wright ups of fires after a while of driving in this condition.

I am submitting a complaint regarding my 2020 Jeep Gladiator, which has exhibited persistent and dangerous steering issues since shortly after I purchased it. The issue is commonly referred to as the "death wobble." Despite 5 separate repair attempts performed by an authorized Jeep/Stellantis dealership, the safety defect continues to occur. This issue is very commonly know to Jeep. I have even been told my the Service Agent I worked with at the dealership that the steering damper is known to be inadequate, but still continually put on the Jeep. The issue started at approximately 25,000 miles, and upon the 5th time bringing it in for the same safety defect, the car is at 92,000 miles. At highway speeds, if the vehicle hits any uneven pavement, the car will begin to shack violently and the vehicle becomes difficult to control. On multiple occasions, the vehicle felt uncontrollable. This creates an extremely unsafe driving condition for me, my family, and other drivers on the road. I have to be hyper focused to avoid any pothole or other change in pavement in order to try and prevent the steering defect to happen. Even when the steering damper has been replaced, the new one can break at any point again, creating a danger every time this vehicle is driven on the highway. I have opened a formal complaint with Jeep as I can no longer use the vehicle in good conscious with my 4-month old daughter. The defect-steering damper breaking can happen anytime, as the exact same part is replaced each time with no successful remedy. I am asking the NHTSA to investigate the steering defect, determine whether a broader safety recall is necessary, assist in compelling Stellantis to provide an appropriate remedy for a vehicle that has undergone multiple unsuccessful repair attempts for a safety-critical defect. I have included all service documents and my communication with Jeep/Stellantis.
