Example complaints

“While driving up on the leveling blocks, 9 of them shattered. Hard plastic pieces of the blocks became shrapnel that flew across the driveway. Had I been standing where I normally do, I would have been hit by the shrapnel and suffered injury. When I tried to contact Amazon for a refund, I noticed numerous photos of broken blocks in many of their reviews. I contacted the company in July, August, and again in October to no avail. Finally, last week, I received an email from their representative, Chris Phillips, who at first told me that we had used their product incorrectly. …”
NHTSA complaint #11552669, filed 2023-10“The hydraulic leveling system, a Lippert system failed. The hydraulic line on the driver's front leveling jack ruptured, causing hydraulic fluid to spray on the hot engine and exhaust. The engine was immediately turned off preventing a fire. The other danger is that this hydraulic line was holding the jack UP, and could have caused the jacks to drop to the pavement but fortunately we were not moving. The hydraulic line is thermoplastic and not made for high temp locations.”
