While returning from work the engine just shut down. It would not start. I thought it may have been the battery. It would barely turn over purchased a new battery and installed it . This all took about a hour and a half. Started the car and it knocked rattled and and squealed. I shut it down and had it towed home. I have no warning lights or codes on the dash what soever the motor sounds like trash.
The vehicle began running rough on the highway and a display said service battery charging system. Pulled to the shoulder and turned off car. Attempted one restart but the engine sounded rough so shut it off immediately. Car towed to mechanic. Mechanic found 3 codes related to the timing chain and metal shavings in oil and filter. Engine needs to be replaced.
The vehicle started making a noise in the engine, took it into the dealership and they said they thought it was something different. A week later the car started to drive badly and the engine sounded worse. After work I tried to start the vehicle and it wouldn't start. The numbers on the sensor reader stated it was the timing chain. We got it served by a mechanic and the timing chain when it slipped damaged the engine. Now we haven't been able to drive the travers for over a year and we are still paying for it because we now need to put a new engine in it. The dealership and the manufacture were of no help to us. I also would like to make mention, we did have our oil changed regularly.
Engine issues appeared around 80k miles. Started as a pinging sound when driving one day, within 20 minutes and without warning, check engine light was on and power was very limited. Was driving on a two lane road and was able to immediately pull over, could have been a much different situation if this occurred on the highway or in a high traffic area. Had the car towed to the dealer who reported engine failure and "replaced 2 rods. " covered under power train warranty. Not even 1 year later, at 100,750 miles, the engine failed again. Same sound when pulling out of the driveway. Immediately parked and had car towed again.
