Two problems related to engine rattling and whining sounds have been reported for the 2017 Jeep Renegade. The most recently reported issues are listed below.
The engine ignition coils had gone bad, causing the car to break down while running errands in town during this covid situation. The car only had about 38,000 miles on it and I'm the original owner. I was able to get it into a dealer same day & they replaced a coil & spark plug- getting the car back on the road. They also replaced the stereo due to electrical problems. This cost was partially covered through my Toyota care warranty. Other problems:the transmission also has trouble finding the right gear when accelerating & often jerks or stalls. There is also a vibration/ rattle sound coming from the engine compartment in front of the passenger side. My dealership doesn't want to help figure out the other problems, if the car is operating. They are clearly too busy to invest the necessary time & probably are receiving multiple complaints like mine. And I just read an article about fca are considering a full recall of the 2. 4 tiger shark models. Very disappointed in Jeep quality and service.
Check engine light on, bad thermostat. Engine making a rattling noise different than the normal unique sound of the 2. 4l multi-air engine after engine is driven on the highway. Sound can be heard most when traveling under 40 mph.
