Front seats “shifting”
Hello all,
Last week, my car has developed the very annoying & infamous front seat shifting problem. It’s gotten to the point that any turn I make, the seat shifts to the opposing side of the turn, and I’m highly annoyed given how much we pay for these vehicles. Has anyone tackled this DIY? I’m prepared to set aside some time on a weekend to Remove the seats to replace the railing or whatever causes this issue. Any help or info would greatly be appreciated! 😊 |

No, it’s not that. It’s an actual defect in the design of the seat that many owners within our platform complain about.
Any strong g-force while turning allows the seat to move from side to side. The passenger seat also rattles in certain positions over rough pavement because of this issue, and I consider it to be highly unacceptable in a vehicle of this caliber. |

I had the same problem and the solution was to replace the entire seat frame. Check out this link for a long discussion about the problem. See my post #50

I had BMW replace my driver seat frame or whatever parts it was. They weren't sure about it initially and I said well as the seatbelt is attached to the seat I don't want the seat and me attached to it to all go flying somewhere out of the car.
That shut them up instantly and I got it fixed. If your car is out of warranty I'd have a crack at saying that and see how they react

Below is what was reported by the Dealer to fix the same problem. What I reported to them was that I was getting side to side movement on turns.
They ended up replacing the "seat frame". I've never seen a mechanical wear problem solved by a lubricant. Last edited by Walt White Coupe; 04-08-2021 at 08:22 AM.. |

I can confirm that Teflon spray will indeed work. You will need to lubricate every couple of months. What I found to be an even better and long term solution is brake caliper pin lube/anti-seize. It has a thicker consistency which is why I'm assuming that solution has lasted longer for me. It has been about 6 months since I tried the brake caliper lube and no issues.

I happen to have both But yes, my statement was around the fact that if the seat base is loose and the seatbelt is attached to the seat so there is potentially a big safety issue.

So the Z models (Z3/Z4/Z8)...and some of the convertible 3 & 4 series may have front seats with incorporated seat belt restraints.

Easiest way to access the "bushings" is the move the seat to the furthest position backward and raise the front of the lower seat cushion to its highest position. Now look under the front of the seat and you will see a bar running horizontally with 2 "closed horseshoe" looking bushings toward either end. You need to lubricate the area where the bushing travels on the bar when the seat shifts. Hope this helps. |

I used some WD-40 Specialist Anti Friction Dry PTFE Lubricant on my bushing 6 months ago and worked. Just after doing it again there because it started to shift
