2 Equipment problem of the 2016 BMW Z4

Failure Date: 08/01/2022

The air conditioning system has a very very foul musty smell when you first start the vehicle after sitting for a few hours. It will go away after a few minutes, but the dealer nor repair shops can fix the issue. System was cleaned, new micro air filter was installed, but still have the musty odor. Even the a/c drain was cleaned, all to no avail. This seems to be a class thing with all BMW vehicles according to the many BMW owners I have spoken with. But no one can fix the problem.

3 Equipment problem of the 2004 BMW Z4

Failure Date: 09/26/2021

The electric top malfunctions because of fault design behind the driver seat is a hydraulic cylinder that sits in a cabin. Water leaks into the cabin causing the hydraulics to go out. The cabin fills up with water, and submerges the pump. This is a major design flaw. It is common with all Z4 models 2003 - 2008. I have a roadster rental business, comprised specifically of the Z4 model. I can give you 4 different vehicles I own as an example. Plus I can quote every seller, that says the top does not work. If people are not aware of this it can lead to accidents, the claw hooks disengaging, unable to get the top up in a lightning storm, rain storm etc. , I haven't seen any recalls on the tops. There are no warning lamps on the vehicle that indicate the top motor or its hydraulic cylinder are malfunctioning. Most of these tops quit working in the same year or a couple year after the car was purchased, from manufacturing date. My car, I have reported here, only has 75,000 original miles.

4 Equipment problem of the 2003 BMW Z4

Failure Date: 09/01/2019

Convertible top motor is placed in a bad location by the manufacturer causing roof pump motor to cease and stop working. This is a safety issue because the top should be able to be put up due to inclement weather. My convertible roof won't go up or down right now. Hundreds of complaints online and BMW wants to charge over $2,000 to perform repairs gauging customers for their faulty designs.

5 Equipment problem of the 2011 BMW Z4

Failure Date: 03/07/2019

The parking brake failed with an amber indicator showing on the dashboard when starting the car. Had to put the car in gear (6sp) and then get out and chock the wheels in order to keep the vehicle from rolling down hill. Independant repair station informed me there was an error code - 6017 wheel speed sensor dfa_emf in the parking brake module. This error is in fact a bug in the software and required a new verion of code to be loaded at the BMW dealer for a cost of $430. BMW has been aware of this problem since at least 2013 and has not issued a notice or recall. This issue affecting hundreds of Bmws needs to be invesigated due to the obvious saftey concerns.

6 Equipment problem of the 2006 BMW Z4

Failure Date: 05/18/2018

The convertible top failed 2011/30229 miles, still under cpo warranty. The dealership only topped off the hydraulic fluid and claimed no leak found. It failed again 2014/45809 miles. This time seals were replaced and hydraulic lines. Goodwill repair with 50% out of pocket. It failed again earlier this year 2018/62112 miles. This time I was quoted $2,938 to $3,658. I had it diagnosed in may and was waiting for an answer of the service manager about BMW assisting with the repair and had not heard back. I inquired again two days ago and got a reply that BMW would not pick up any of the repair cost. It appears that it was a slowly developing defect. Where would have the fluid have gone at the first repair? also doing some research turned up a lot of the same trouble for other owners. Apparently it is a design flaw. Water not draining because of clogging and consequently causing damage to the hydraulic system.

9 Equipment problem of the 2003 BMW Z4

Failure Date: 07/03/2015

The central locking system does not work correctly. It operates the glove box, passenger and driver doors as well as gas cap door. It does not respond properly to fob or by key. At times all locks are frozen to the point where you can not open to get in or gas. Right now passenger door has been locked for 30+ days. Cannot open at all. Took to a mechanic who ordered a new actuater from BMW dealer, first one did not work. Second one installed and the problem is not solved. ($240. 00). Mechanic tells me that something is burning and I must take to dealership. I can smell the burning and I am afraid and will not drive. Looked up on internet, there are 100s of consumers with the same issue. This car only has 71,000 miles on it.

10 Equipment problem of the 2015 BMW Z4

Failure Date: 03/07/2015

I had a very frightening transmission malfunction on Saturday, March 7 in my 2015 Z4 (three months old). I was heading down a slope into a parking lot and stopped to pick up a ticket at the kiosk. The car was in drive and my foot was on the brake. Once I got the ticket, I took my foot off the brake and the car started driving backwards! I stopped immediately (luckily there was no one close behind me) and tried again. Same thing. So, I put it in park, then back in drive and it drove normally. Fine. From there, I had to go to the store. When I got there, I turned off the engine (and the key was in my purse) and, of course, it went automatically into park, as it always does when it turns off. Sitting in my parked car, I went to get some stuff out of my purse and with the engine turned completely off, before my very eyes the gear shifted from park to reverse and my car started moving backwards. I quickly hit the brake and put on the emergency brake. BMW assist came out to pick up the car and bring it in for service. Everyone agrees they have never heard of such a thing, but it is 100% true and scared the life out of me. I'm afraid to go back in my car, now.

11 Equipment problem of the 2009 BMW Z4

Failure Date: 05/24/2014

The car has stalled multiple time when coming to a stop. In some instances I did not have to come to a complete stop such as crossing a divided highway, just slowed significantly. As I went to accelerate through the intersection the engine had stalled and I was stuck in the middle of the intersection with no power. Car starts right back up each time but you must stop to place the car in drive(automatic transmission). Nearly hit by oncoming traffic on 3 separate occasions. Dealership was able to replicate, sold me a $400 battery as the fix. Car stalled on the way home from dealership. Returned the car but they could not replicate and since the instances did not produce a fault code they could do nothing. Car continues to stall which makes it a safety hazard. There are 100's of post on BMW forums with the same issue but BMW claims to have no knowledge of the issue. Someone needs to step in and make them address the issue. This is not the known battery cable issue, that was replaced per recall.

12 Equipment problem of the 2004 BMW Z4

Failure Date: 07/22/2013

The steering is the only problem but your web site insists on my selecting at least 3 affected parts. In any case, the steering recently became jerky and notchy while driving. After several days of this, I took it my local foreign car repair specialist and they diagnosed a problem with the electronic power steering. Ultimately, they replaced the entire steering column at a cost to me of $4100. This was a very unsafe condition making my control of steering tenuous at best and one that you have received numerous complaints about.
