There will be issues with anything, but those years seem to be less problematic than much of the newer stuff. Also, depends on mileage.
1. Coolant temp sensor and thermostat
2. Potential valve body issues with 10 speed. (Not sure if 19-20 years were affected)
3. Coolant T fittings at firewall
4. Corroded coolant and A/C lines along passenger frame rail (if in a salt road area)
5. Leaking front struts - replace with OEM
6. Rear air shocks and compressor - OEM only recommended
7. Vacuum pump for brake assist (TSB about low assist - again not sure if 19/20 affected)
8. Potential AFM problems if oil not changed religiously or driven like it was on the set of The Fast and Furious.
This is just a cliff notes version of what has been discussed over the years here. Others will chime in and correct me if needed and add to the list.
Overall, they are well built vehicles. I love my 2017, but it had its growing pains along the way. I'd buy it again though.
