The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while his wife was refueling the vehicle, fuel sprayed back out forcefully into her face. The contact's wife was transported by ambulance for facial and upper body burns due to the fuel. The contact was unaware of a police report being filed.
When I try to put gas into my tank, the pump cuts off. It takes five minutes to get $16 worth of gas! It's getting worse. I've tried different pumps, different gas stations nothing helps. The dealer claims to know nothing about it. Today, the gas was spit back out! So I have shoes and feet soaked in gas! It is a capless gas tank
Transmission problems. The transmission shifts are pronounced, cause the SUV to jerk and feel jumpy. This condition is sporadic, and can change based on mode - normal, eco off, sport . Besides causing a choppy ride, the condition is unacceptable and may be a r a precursor to gear failure
At a gas station, with the engine turned off. On 3 different occasions, when filling up my gas tank, when I start pumping gas, the tank stops taking gas as if the tank is full. In order to continue filling the gas tank, I have to hold the gas hose handle in a specific position to allow the gas to fill the tank without stopping.
I have only owned the vehicle for 5 months. When filling the gas tank on several different occasions at several different pumps, the pump stops like the tank is full even though I just started pumping.
