I purchased this 2018 Jeep Wrangler JK Unlimited on July 19, 2025. Since purchasing the vehicle, I have experienced repeated mechanical failures that have required multiple repairs. The most serious issue involves the engine overheating at highway speeds without any visible coolant leak or clearly identifiable cause.Despite seeking professional diagnosis, the source of the overheating could not be determined. Shortly afterward, the vehicle developed a P0302 (Cylinder 2 Misfire), raising concerns about possible internal engine damage caused by the overheating.I believe this presents a significant safety hazard. An engine that overheats unexpectedly while driving at highway speeds can lose power or fail without warning, creating a dangerous situation for the driver and surrounding traffic. The vehicle has become unreliable and unsafe to operate because I cannot predict when it may overheat or experience another engine failure.As someone who often drives alone, I no longer feel safe taking this vehicle on long trips. I am concerned that the vehicle could leave me stranded on a highway or in a remote location without warning, placing my personal safety at risk. A vehicle should provide dependable transportation, not expose its occupants to the possibility of sudden mechanical failure.This vehicle has spent more time in repair facilities than on the road. I have incurred thousands of dollars in repair expenses, and I am now being asked to pay for an engine teardown simply to determine the cause of the failure before any warranty consideration can be made. Despite multiple repair attempts, the underlying cause of the overheating and engine problems has not been resolved.I am submitting this complaint because I believe the repeated overheating, unexplained engine malfunction, and resulting cylinder misfire may indicate a safety-related defect that warrants investigation. I request that the review to determine whether similar failure whether a broader safety issu

The instrument cluster display in my 2018 Jeep Wrangler Sahara has failed. The display is either blank or nonfunctional, preventing me from viewing critical vehicle information and safety warnings while driving. This failure affects my ability to monitor engine temperature, fuel tank capacity, warning messages, fault indicators, and other important vehicle operating information. As a result, I may not be alerted to potentially dangerous conditions such as engine overheating, low oil pressure, charging system failures, or other safety-related issues. I am aware that Jeep has issued recalls involving instrument cluster defects on certain Wrangler vehicles, but my VIN is not included in the recall. The symptoms of my vehicle appear similar to those reported in recalled vehicles. Because the instrument cluster is a primary safety component used to communicate vehicle warnings and operating conditions to the driver, I believe this defect presents a safety risk. I am submitting this complaint so the issue can be investigated and to determine whether additional vehicles should be covered.
