I have a 2002 Hyundai Elantra GT with 99,500 miles.
My question is the following - is it possible that the struts on this car are in some way dependent on the battery?
Here’s what happened to me recently -
I got my oil changed a few weeks ago at a local garage. They also checked my battery and told me it would need to be replaced sometime this winter. They must have disconnected the battery to test it because I had to reset my radio clock. When I drove off, I went through a parking lot with speedbumps and noticed a huge change in the function of the struts - it shook like crazy. I took it back to the shop to ask what happened and they said there was nothing they could have done to cause a problem with the struts. They did examine things by putting it back up on the lift and low and behold when they did that they noticed that all four struts were stuck and not working properly, they were all suddenly frozen. They had no explanation as to why it happened but the mechanic suggested I try driving it for a while to see if they’d get unstuck on their own. I did some research and found a few mentions on the web about other Hyundais doing the same thing when they’re put up on a lift that doesn’t lift by the tires and they’re hanging unsupported in that position for an extended period of time. I’ve driven a few hundred miles since then and I think they improved some over this time but they still didn’t seem right. This week my battery died and I had to get it replaced. After replacing the battery, I think my struts are working a lot better. So I’m trying to figure out what’s going on. The mechanic said there was no connection between my battery and my struts but I’m starting to wonder. Is it possible that my struts get some type of benefit from having a fully charged battery? Why would my struts have frozen in the first place after being on a lift for an oil change and having a battery check? I had gone to same garage for my prior oil change and didn’t have any problems after that one, but I don’t think they checked my battery last time.
