09/16/2023: Engine caught fire arrived at work at 830am and left at 4pm. Went to fedex (5 min away from job) and noticed burning smell. Left fedex (was there less than a minute because I was dropping envelope in drop box) and noticed smoke coming from under hood. Drove about a block and while making a left turn I noticed more smoke coming from under the hood. Pulled back into job's parking lot (since it was close) and within 5 minutes the engine was in flames. Flames were extinguished, but car was no longer driveable. Insurance claim was filed and vehicle was deemed a total loss. Cause of engine fire is still undetermined per insurance company.

This vehicle and model have a defective engine; I have made several attempts since I purchased this vehicle from the dealership to have this issue corrected, and nothing has been done. This is a very common issue with this particular engine, and it is a well-known problem; there are several class action suits regarding this engine, and the manufacturers still have no resolution for it. The vehicle requires constant new oil in between oil changes and has been like that since new. The engine burns oil, and it is not going anywhere, nooen seems to know.

I keep having the same issue with this vehicle's fuel/propulsion system, power train, engine, cruise control. This vehicle is need it's fuel system cleaned now for a 3rd time in less then 2 years. I have done the high mileage maintenance on it as well. I drive the vehicle less than 5,000 miles a year. When I am driving the vehicle, it struggles to speed up, making me press on the gas repeatedly to get to the indicated speed limit. The vehicle does not slow down as it should when pressing on the brakes. I have to press repeatedly over and over and harder on the brakes in order for it to slow down. The vehicle jerks, speeds up without me pressing on the gas and sometimes it will not stop when prompted. I cannot put this vehicle on cruise control, because it speeds up and out of no where, it accelerates causing me to almost collide with another vehicle or object. Even when the vehicle is not in cruise control, the sudden jerks and acceleration puts me, my children and others in harm when it suddenly speeds up, jerks or will not stop in time. It makes a loud noise and jerks even when the car is in a resting position. It loses power, it speeds up when i need it to stay the same speed or slow down. I fear this vehicle is unsafe. I have reported these issues and a few more to the dealership who never responded, so I had to go over their heads, then finally I got a response from their Consumer Affairs' Department, as well as the BBB and they state because of the vehicle's age and/or mileage there is nothing they can do about it. Please help me. This is the only vehicle I have, and I am a single parent who cannot afford another vehicle. What is going on with this car? Why do I have to keep struggling to pay for something to get fixed and it is still not solved. Below, it ask for a date, but it is multiple dates, not just one. I have listed the first time it occurred. Thank you.

The first time my engine light came on was about a month after I had purchased it. The dealership told me to go to autozone to see what it could be. Report said it could possible be an oil clog or oil change. I got an oil change and the light was off. Light came on an every now and then but the car was driving fine. I got another oil change at the recommended mileage. My car won-??t start now, I thought it was a battery issue so I took it in to a mechanic to have it looked at and they said I need a new engine.
