“When driving in low speeds, the car is very jumpy and seemingly inconsistent with the amount of fuel delivered to the pedal. The car seems like it will almost stall out, then I have to push the gas pedal further down to deliver more gas, but then it makes me go to fast and jumps.”

NHTSA complaint #11360194, filed 2020-09, 100 miles

“Traveling on highway at 70 MPH when a deer jumped in front of our car and we hit it with the front end of the vehicle crushing the front end. All air bags immediately deployed and the front end began smoking profusely. Within minutes of getting out of the vehicle it burst into flames and the entire vehicle burned up. Concerned that these vehicles will burst into flames during a front end collision at high speeds.”

“My fuel pump was replaced (according to the dealer) based on the most recent recall. However now it idles and runs rough just a short time after this service. I recently read there is another lawsuit or issue with this fuel pump and the symptoms are the same.”

NHTSA complaint #11363767, filed 2020-10, 23,314 miles

“When the car idles for even short periods of time (5 minutes) the inside of the car will start to smell like fumes (exhaust type smell). This happens in any environment (parking lot, our driveway, rural area) when the car is in park and still running. Rarely have I smelled the fumes upon starting the car, although it has happened before. The problem has occurred in every season and with the car blowing out warm, neutral, and air conditioned air. This was noticed very shortly after purchasing the car in september of 2018. …”

NHTSA complaint #11323121, filed 2020-05, 15,000 miles

“Gasoline vapors in cabin and around car. After the vehicle has been parked, gasoline vapors are accumulating around car. We experience strong gasoline vapors in our enclosed garage after driving (appearing 10-15 minutes after turning car off). Also, after driving for even a short period of time, then turning the car off, then starting again, gasoline vapors enter the cabin through the vents (if non-recirculating). Dealer confirmed we gasoline mixed with our motor oil (dealer changed the oil, but didn't correct the problem). While this is alarming enough, the smell continues. …”
