Exterior lighting

10 reports
“I WAS SENT A LETTER ABOUT THE RECALL AND I SENT IT BACK SAYING I COULD NOT AFFORD TO PAY UP FRONT. THE SENT ANOTHER LETTER ABOUT THE DEADLINE AND I SENT BACK I COULD NOT AFFORD TO PAY UP FRONT. I NEVER GOT A RESPONSE BACK. MY LIGHTS ARE GETTING DIMMER AND CAN'T SEE AT NIGHT. THIS IS A SAFETY HAZARD THAT I DIDN'T CAUSE AND SHOULD HAVE BEEN REQUIRED TO REPAIR. I BOUGHT THE VEHICLE USED AND HAVE A FEW PAYMENTS LEFT. THIS IS A SAFETY ISSUE AND IT'S INCONVENIENT. THIS NEED TO BE INVESTIGATED.”

Electrical system

10 reports1 related recall
“DRIVER SIDE DOOR WOULD NOT OPEN FROM OUTSIDE WITH KEY OR FROM INSIDE WITH MANUAL LEVER. THE DOOR LOCK BUTTON WOULD NOT MOVE TO UNLOCK DOOR BY THE ELECTRIC SWITCH OR BY HAND. I HAD TO EXIT VEHICLE BY CRAWLING OVER CENTER CONSOLE AND EXITING PASSENGER SIDE. AT SOME LEVEL I CAN UNDERSTAND THE ELECTRICAL DOOR CONTROL FAILING, BUT I DO NOT FEEL IT IS SAFE TO NOT HAVE A MECHANICAL OPTION TO OPEN THE DOOR UNDER ELECTRICAL FAILURE. THIS FIRST HAPPENED WHILE VEHICLE WAS PARKED. MECHANIC NEEDED TO CRAWL IN THE PASSENGER SIDE AND REMOVE DOOR PANEL TO REPLACE DOOR LATCH ASSEMBLY. 62014 ON ODOMETER AT REPAIR TIME.”

Suspension

7 reports2 crashes
“A combination of the lower control arm alignment adjustment bolt, it is just a slot and standard bolt. The alignment becomes loose over time and begins to work side to side in the slot, so retightening the bolt is the only solution to keep it from moving. The main issue is the subframe being made from aluminum and the machined slots for the lower arms, the "ears" for the lower arms are not machined or reenforced correctly which lead to severe fatigue cracks in the machined radius of the subframe. These cracks will cause the lower control arm to break free of the mounts and causing the front suspension to shift to the left or right and causing a crash. All it will take to break them off is a large enough bump and this WILL kill or injure someone.”

Service brakes

7 reports3 crashes
“There have been a collection of other Vin numbers for this year make and model for the symptoms I have been experiencing since taking ownership in 2019. The vehicle will stall while running and randomly disable ALL WHEEL drive, Traction Control, ABS, and send Check engine light on causing me amdy son on infinite number of times to almost be hit In the middle of amd intersection, after a stop sign at low speeds, upon turning the wheels into or put of driveway, parking spaces and worst off at 60 mph on a freeway. This has resulted in multiple near accidents as the vehicle randomly disables itself. It occurs mostly after pressing the brakes to shift gears and almost always causes the vehicle to become inoperable for over an hour where it sits as there is no option to disable AWD or choose from FWD OR RWD. It happens in manual mode (or called performance mode) as well as automatic mode and has been occurring for 5 and a half years. I have been charged an exorbitant amount for supposed repairs from.dealers and mechanics who have claimed to fix it and I have severe autoimmune disease, a foot prosthetic, AND a minor child I have to transport to and from.school in the…”

Air bags

6 reports2 crashes
“"service air bag" light is illuminated. Deal states the replacement part is out of production. Apparently, this is a relative common problem with this vehicle. The illumination of the warning light indicates the air bag system is not working.”
