Owners report gasoline leaks from the fuel sender unit, often due to a cracked plastic housing where the fuel hose attaches. This can lead to a strong fuel smell in the cabin or garage, posing a fire hazard. Regular inspection of the fuel system is crucial.
There are reports of engine fires, possibly linked to electrical issues, and melted wiring harnesses, such as near the headlight connector. These can be expensive to repair and pose safety risks. Check for any signs of electrical burning or malfunction.
Some owners report that airbags did not deploy in accidents, while others see the airbag warning light illuminate, indicating a system fault. This could be due to wiring issues or sensor problems, and it's vital to have the SRS system checked by a professional.
There are complaints about engine performance issues, including poor idle and loss of power, often linked to timing chain or balancer shaft wear in certain V6 engines. Additionally, some vehicles have trouble shifting out of park, requiring shifter assembly replacement.

The most common issue is harsh or delayed shifting, especially in the 10-speed automatic transmission (10R80). Owners report jerking, clunking, and even sudden loss of power while driving, which can be dangerous in traffic. Transmission problems may require software updates or internal repairs.
Electrical complaints include warning messages like 'Front Camera Malfunction' and 'Pre Collision Assist Not Available' appearing on the dash. These can be persistent and may indicate issues with sensors or wiring, affecting driver-assist features.
There are numerous complaints about headlight failures, including condensation, flickering, or complete failure. This can reduce visibility and safety, and replacements may be costly.
Engine-related complaints include stalling, rough idling, and loss of power, which could be due to various issues like fuel system problems or sensor failures. These can be intermittent and hard to diagnose.
