“Trunk strut failed after only about 3 years. My dad gave me the car and he was just willing to live with it, as he is very ill the car had passed the 4-year, 50,000 mile point, but I was struck by the falling trunk and wish it repaired.”
NHTSA complaint #10244211, filed 2008-10, 45,000 miles“Trunk support struts not functioning appropriately, causing trunk lid to abruptly fall and injuring anything in the path of closure. We noticed the increasing lack of ability to hold the lid open, never understanding that it actually was suppose to also lift the lid (it never did lift the lid and we have owned the car for four years/ 45,000 miles) and could have been potentially replaced during the warranty period (seems like early life failure). When asking the dealership service advisor he said, yes these do seem to weaken often and they could be replaced for $500. …”
NHTSA complaint #10247288, filed 2008-10, 38,000 miles“The piston-like air struts that are supposed to hold the rear trunk lid open on my 2003 Lexus ls 430 (bought new in december 2002) slowly stopped functioning starting around 4 years ago. Now they do not work at all. While this is an inconvenience to have to open the trunk manually, the real danger is that are no provisions to hold the trunk lid in the open position. Thus, even a light wind or vibration caused by passing vehicles will cause the trunk to teeter off the open position and slam shut. …”
NHTSA complaint #10406010, filed 2011-06, 30,000 miles“Trunk lid support on 2003 Lexus LS430 does not support the trunk lid thereby allowing the lid to fall and strike the person on the head while placing objects in the trunk. Dealer does nothing to correct the problem.”
NHTSA complaint #10298543, filed 2010-01, 20,000 miles“Trunk struts failed to hold the trunk in an open position, causing the trunk to fall and injure a person. Multiple times. Trunk was properly opened and raised to a full open position.”
