I have a 2013 LX570. One of the hydraulic lines on the AHC system burst with just 86,500 miles on the odometer. The dealer says this was due to rust and corrosion. To replace the line I was told that the body must come off the frame. Additionally they can not say if other parts need to be replaced due to the corrosion. Because they can not pin down a price for the repair, they quoted me a maximum $36,545. This is the cost to replace the entire AHC system, if necessary. I believe the entire vehicle only has a value of about $40,000. Do I OK the repair and hope the bill is nowhere near that high, or do I write off the truck? Is there an aftermarket conventional suspension system that can be installed? Other than the suspension issues the truck is in excellent shape. Thank you in advance for any advice.
