Bmw Z4 problems
The BMW Z models are a line of roadsters manufactured by German automaker BMW. The Z stands for Zukunft (German for future), and has been produced in four different series with six generations consisting of roadster, coupé, sports car, and concept variants.
The introduction of the M Coupé and M Roadster in the Z3 line marked the first of the Z series to have a high-performance BMW M variant. The first generation Z4 also continued to offer M Coupé and M Roadster variants. The current Z4 (G29) uses BMW's (B58B30) inline-six, its platform is the basis for the current Toyota Supra.
BMW Z1 (E30 based; 1989–1991)
The BMW Z1 is a two-seat roadster developed by BMW and was produced from March 1989 to June 1991. It was based on the E30 3 Series platform. The Z1 featured unusual doors which, instead of opening outward or upward, dropped into the door sills and had body panels which could easily be removed and replaced; the car could be driven with all its body panels removed for weight reduction and increased performance. Only 8,000 examples of the Z1 were produced.

Common Bmw Z4 problems
The BMW Z4 is a popular sports car known for its sleek styling and exhilarating driving dynamics. However, like any vehicle, it can experience common problems that owners should be aware of. Here are some of the most frequently reported issues with the BMW Z4, based on complaints from owners:
- Exhaust Rattling: Some Z4 owners have reported hearing a rattling sound coming from the underside of their car, particularly when driving over speed bumps or other rough surfaces. This issue is usually caused by a faulty flap in the rear section of the exhaust. Fitting a replacement flap should take care of this problem, which is typically inexpensive to fix.
- Brake Line Issues: Rust and corrosion on the brake lines is a common problem with the BMW Z4, and it doesn't seem to correlate with the vehicle's age. Brake line issues can be expensive to fix due to the difficulty of removing and replacing them.
- Squeaky Roof: A squeaky roof can be an annoying issue for Z4 owners, particularly if they live in areas with a lot of tree sap or debris. Keeping the roof clean and covered can help prevent this problem. If the roof still squeaks, it may be necessary to tighten the latch-locking mechanism to ensure that it seals properly.
- Roof Mechanism Problems: Some Z4 owners have reported issues with the roof mechanism, such as the roof coming halfway down and then stopping. This issue is often caused by water seeping into the trunk seals, which can damage the roof's hydraulics and electronics. To fix this problem, it's usually necessary to replace damaged parts and fix the issue causing the seal problem.
- Window Regulator Cable Failure: As the BMW Z4 gets older, there's a greater chance that the window regulator cables may fail. This issue is typically caused by a problem with the window regulator cables, which can result in a scraping sound from inside the door when rolling the windows up and down. Replacing the entire regulator is the recommended solution to prevent the problem from recurring.
While the BMW Z4 is generally a reliable vehicle, these common problems can affect its drivability and require expensive repairs. It's essential for Z4 owners to be aware of these issues and take preventative measures to avoid them whenever possible.

- VIN: 4USBT53493L
- Components: STEERING
- Summary: When outside temp is 80degrees or higher it becomes difficult to maintain the vehicle in the correct driving lane due to a stickyness in the steering wheel.

- VIN: 4USBT33493L
- Components: STEERING
- Summary: My girlfriend, [XXX] , purchased a used 2003 BMW z4 2.5i. It is pristine with 47K original miles. Always maintained, garaged and never driven in foul weather. I, [XXX] , drove it home for her and noticed the steering to be "sticky". This showed on the highway traveling at 65 MPH. It was very unsettling to feel the car want to track in a direction that i could not control. I used "more force" to pull the steering wheel to get tracking correctly and stay in my travel lane. Lucking I did not overcorrect and lose control or cause and accident. Once it happened it continued to happen the balance of the drive on the highway and back roads. I've owned and driven many different makes and models of vehicles from Dodge, Renault, Toyota, GMC, Chrysler, Volvo, Geo, etc. and never has "steering" been an issue. Once we got home I looked up "sticky steering" issue for the 2003 Z4 and this is a known issue. Driving this BMW was unsettling and unsafe.

- VIN: WBAHF3C55KW
- Components: ENGINE
- Summary: My grill shutters are faulty and the problem has been persistent and the vehicle is only at 30,000 miles. This is the same part that was issued an extended service contract by BMW for various other models. I believe my model is rare enough to not be included but it should. The existing recall/warranty is “SIB 01 12 19 FRONT GRILLE UPPER/LOWER ACTIVE AIR FLAPS: LTD WTY EXT TO 15 YEARS/150,000 MILES” and I believe mine should be included in this as it is the same engine as these various models.

Bmw Z4 2004

- Date Complaint: 2023-09-08
- VIN: 4USBT33514L

- Summary: The steering sticks, in warmer weather, at freeway speeds. Continuously trying to unstick the steering wheel, with the possibility of overcorrecting, at freeway speeds, could present a safety hazard. Yes, the alignment company recognized the problem during their post-alignment test drive. The vehicle has not been inspected by "manufacturer, police, or insurance representatives." No warning lamps/lights/messages on dash. However, if you google 2004 BMW with sticky steering, you will find NUMEROUS accounts of this happening to other owners of similar vehicles (specifically 2003-2005 Z4).
Bmw Z4 2006
- Date Of Incident: 2023-09-03
- Date Complaint: 2023-09-03
- VIN: 4USBU33536L
- Components: ELECTRICAL SYSTEM,EXTERIOR LIGHTING
- Summary: I have just found out that my 2006 BMW Z4 Convertible has serious wiring issues. The wires for example on my front headlights the insulation is falling off the and leaving bare wires. I am very concerned this could be a fire safety issue that could result in bare electrical wires shorting together and starting a car fire. My research shows that many people who have 2006 BMW Z4 Convertibles are having this same issue. This seems to be a real issue with BMW using cheap wiring harnesses material and over time due heat and cooling is cause the insulation to fail and resulting in this issue.

I've always wanted a BMW Z roadster ever since I test drove a Z3 in San Diego. Despite having a mountain of debt at the time, I was working full time as an Engineer. When I finally had the means to purchase my dream car, I had to wait 7 long years for the abomination that was the Z3's successor, the first generation Z4, to leave the stage. But the E89 Z4 was worth the wait! Strangers and acquaintances alike come up to me all the time to tell me that I have a beautiful car. I don't need a car that costs any more money, has any more performance, or looks any better (if possible).

Vehicle year: 2007
I really like this car! The styling is great and the straight-six engine sounds amazing. The manual gearbox is super-smooth and the seating position is perfect. Even with the top up, there's plenty of interior space and it's easy to fold down. The car is so much fun to drive and it gives you a lot of confidence. The brakes are amazing and stop the car with ease. The only downside is that the interior build-quality could be better. Although the one-piece door panels are great, the steering column is tilted and there are a few minor issues like a broken cup holder (which I don't even use) and a squeaky transmission tunnel plastic trim. However, everything you touch is of high-quality and just driving it takes your mind off its few squabbles.

Nothing beats completely changing your day like hopping into the Z and springing off into the night. I had an incredible driving experience and I'm lucky to have many windy roads to enjoy. It was so much fun!
Are you having problems with your Bmw Z4?
Jevon Ferry 2025-03-06
Vehicle year: 2003
We purchased our jet black '03 BMW with 23,750 miles on it, making it our 5th sports car and our first BMW. It has a 2.5L engine, Premium and Convenience packages, auto transmission, and 18-inch ellipsis wheels with RFTs. The car handles well, although the electric steering provides no feedback through the steering wheel. It accelerates well, especially between 45 and 80 mph. However, the seat bottoms can be uncomfortable after 45 minutes, and there is less interior storage space than a Miata. On the plus side, the trunk is roomy for a sports car, although there is no spare tire with the RFT package. The electronic displays can be hard to read in daylight, and Dynamic Stability Control requires alignments to be performed by the dealer for $90. Overall, it is a beautiful car that draws lots of attention from other drivers and pedestrians. Anyone looking for a fun ride should definitely consider it!
Josiah Rowe 2025-02-28

It's great to hear from you! I noticed that your vehicle may need some attention in a few areas. The front struts, valve cover gasket, transmission seal, and front end grommets all require replacement at 25,000 miles. Additionally, there seems to be some vibration issues with the convertible top. Lastly, it appears that both rear rims have cracked due to a poor manufacturing process. I understand that these repairs can be costly, but I'm confident that we can find a solution that works for you. Please let me know how I can assist you further.

I have experienced several issues with my vehicle, including a faulty steering angle sensor, valve cover gasket and oil housing gasket replacements, and lower control arm bushings. The total cost of these repairs was approximately $2,100.
Brayan Williamson 2025-01-17

This car is beautiful! It has a very sexy and sleek design that just screams performance. While I have had some issues with it, such as a malfunctioning convertible top motor, ABS sensors, starter, and coolant reservoir, as well as regular maintenance costs like brakes and tires, I have kept it for a while. However, I am now considering moving on. This is actually my second German car, and I have to say, I expected better from German engineering!
Warren Daugherty 2025-01-12
Vehicle year: 2003
I have only driven my BMW Z4 2003 for 30000 miles. I bought it out at the end of my lease. Unfortunately, the elec. motor for the convertible top short circuited due to run off water that enters the plastic housing where the elec. motor sits in. The water can't drain and the electric motor will rust and quit. It is a very expensive repair and I find it to be a poor design. I had the housing replaced in 2008 and now it needs to be replaced again. Unfortunately, my extended warranty won't cover the repair nor will the dealership. I also had to replace the rubber around the windshield and the cowel due to dry rot. I would have thought the convertible roof of a BMW would last longer.
