The twin-turbo 4.0L V8 (EA825) engine and ZF 8-speed automatic transmission are very frequently praised for their robust performance, smooth power delivery, and proven long-term reliability when properly maintained, with multiple reports of trouble-free operation beyond 100,000 miles, even on tuned vehicles.
