What owners say about the engine

Verbatim from NHTSA complaints, newest first
“The Hood Silencer Pad (68752887AA, 68292166AA, 68292166AC, 68292166AD) is made from insulating fibers that attract rodents. The rodents detach portions of the silencer pad which can result in loose material that could become a projectile on the highway or contacting hot engine components, potentially creating a fire hazard.”

“My Jeep Wrangler currently has a very strong fuel smell, and when the AC is on the smell is very strong inside the cabin. My kids and I became Ill and had headaches. It's been parked for two weeks. Pending an inspection by an independent mechanic. We came across an article stating that a lot of 2020 Jeep Wranglers with 2.0L motors were recalled because of the same issue but my Jeep was not recalled and I'm having the same issue. Is there anything you can do to help me?”

“Absolutely terrible gasoline vapor filling the inside cabin of the vehicle causing burning eyes, nausea and feeing ill. Checked for fuel, leak, leakage recall, while there was one it wasn’t including our VIN, however, after inspection and repair, it is the exact same damage as what was indicated in the recall. Looking for a full refund for repair and compensation for danger, discomfort, safety and inconvenience of vehicle not being included in the original recall. I am appalled and insulted that JEEP dealerships aren’t more more proactive in having to appeal these dangerous situations.”

“The 2.0L Turbo engine suffers from premature failures. Jeep issued a TSB over leaking around the water pump, but did not notify owners. My engine overheated due to low coolant (there's no low coolant warning), and the temperature gauge proves to be unreliable. My engine suffered a head gasket failure due to overheating, while within the factory warranty period, and Jeep would not honor their warranty. My Jeep only has 33,700 miles on it, and the failure initially happened in 2024. I spent over a year going back and forth with Jeep, and in the end, they simply stopped responding. BTW, tried to upload 2 small .JPG files, but repeatedly said "upload failed".”

“While driving on the highway, the check engine light illuminated. Approximately 5 to 10 minutes later, the battery warning light came on. Upon exiting the highway and coming to a stop at an intersection, the automatic engine Start/Stop system engaged and shut down the engine. When attempting to safely proceed, the vehicle suffered a complete electrical failure due to the 48V mild-hybrid eTorque system failing to restart the engine. The vehicle refused to crank, would not shift, and became entirely disabled and stranded in the middle of a live intersection, creating an extreme safety and collision hazard. The vehicle was towed to an authorized dealership, where technicians officially confirmed the failure. The dealer diagnosed the root cause as an internal electrical failure of the Motor Generator Unit (MGU / Belt-Driven Hybrid Starter Generator Assembly), which completely disabled the vehicle's charging and hybrid restart capabilities. The failed component is available for inspection.”
