On 3 April 2026 I was driving my 2011 BMW Z4 sdrive 30i e89 n52k (manual transmission) that has 31,000 miles on it, suddenly a steering assistance malfunction trouble light appeared and I lost all electronic power steering. This sudden loss of steering control almost caused an accident!! then shortly thereafter the electronic power steering control returned. On April 4 I lost the steering control again and took it to a BMW repair shop. They confirmed that the problem was with the eps (electric power steering control). Upon investigation, a specific recall exists for 2012 BMW Z4 regarding the electric power steering (eps) system. (NHTSA recall campaign #12v302000: electric power steering control module. ) the recall campaign notes that, after the engine is shut off and then restarted, the eps module may function properly. In that case, the warning symbol in the instrument cluster will no longer appear, and the audible warning will not activate. However the condition may occur again. This is exactly what is occurring with my car and you never know when it will occur. The campaign covers 2012 Z4's and covered some cars manufactured in late 2011. However, the VIN for my 2011 BMW Z4 sdrive 30i e89 n52k (manual transmission) is wbalm5c58be162421 and it was manufactured in 04/2010. The eps in my 2011 BMW Z4 is exactly the same as the eps that is covered in the NHTSA recall campaign #12v302000: electric power steering control module. ) clearly my 2011 BMW Z4 should be included in this campaign which requires a 4 hr repair by a certified BMW dealer and replacement of the eps unit. For Z4 models the technicians are to refer to repair instruction 32 13 370, "removing and installing (replacing) electric steering box (eps). " e89 steering gear part # 32 10 6 855 888. Plus following parts: asa bolt (#32 10 6 773 068); hex nut (#33 32 6 768 884); torx bolt (#32 30 6 778 609); combination nut (#33 30 6 787 062). All above referenced parts were listed in the recall campaign. !.
Electrical power steering system failed, warning light came on. Vehicle suddenly became very difficult to impossible to steer. Failed to negotiate a turn and nearly hit a tree. I have an appointment set with an independent service dealer near me, but I’m afraid to drive it there, so I may have it towed. The warning light came on just moments before the initial failure.
On 01/05/2012, BMW service center replaced an idrive part and reprogrammed the car. When I picked up the car, I noticed ac is not working. Service center took it back and did a master reset. After that several times I had the issue and they couldn't fix it. On 07/15/2013, I noticed the ac is not working. It was 85f outside. I called the service manager and drove the car to him. He checked the car and confirmed ac is not working. They took the car and gave me a loaner. Next day they found some error codes stored in the car. While they are looking into the codes, ac started working all on its own. BMW says the error codes are bogus codes and instructed the service manager to clear the codes and return the car to me. Service manager is doing his best to diagnose the issue. But without Bmws help and support he can't fix the issue. It is extremely hot in jacksonville, FL and without ac in the car it is extremely dangerous to drive with a kid in the car.
