https://g29.bimmerpost.com/forums/sh....php?t=1704201 Also you can't conflate "solid feel" with overall long term reliability. They are very different things. My dad had a Benz some years ago. I was young but it was like driving a bank vault. Felt like it was carved from a solid piece of steel. I never drove a car that felt like that before. It was also ALWAYS in the shop.

Apparently not even Hondas are immune from having problems: https://www.edmunds.com/car-news/201...ort-block.html

When I took my car to the dealer this past Saturday, the dealer told me my wiper jumping was caused by the PPF film covering the windshield. The PPF film has too much surface resistance to prevent wiper from traveling smoothly across the windshield. So they help me contact the PPF company (it's the dealer outsourced vendor), and the PPF company proposed a solution by applying a coating on top of the PPF to make the surface slippery. When the job was done, the film surface is much more slippery than before (you can easily tell the difference of before and after, just by touching it with finger). Guess what, problem solved! The wiper went so quietly and smoothly across the entire windshield surface. Unlike before, the wiper was making terrible rubbing noises when wiping. Now the question is, how long will this coating last? I have no idea. Would it gradually disappear after a few car washes? I have no idea. If it can last for a month or two, I would be happy. If that's the case, I would consider buy the coating and apply it at home when needed. Will see the long term results, and report back again. Cheers! |

I'm glad they found out what was causing the problem. My guess is that the more rain you have (I think it rans a lot in Thailand, but don't really know) the more often you would need to replace the coating, if you will be driving in the rain. My thoughts are that the wipers will tend to rub the coating off, so the more the wipers are used, the more often the coating will need to be replaced.

Did you try using cerium oxide?. It will leave a contamination free surface. Its what they use in glass manufacturing to polish glass,mirrors,etc. Then you can use a water repellant or ceramic coating if you wish.

So it is not a standard option and is likely not on any new cars. |

If your windshield doesn't have a PPF, then it's probably worth a try. Please let us know. Good Luck! |

With that said, the PPF on the windshield was recommended by the sales. Without much knowledge and experience on the PPF, I decided to give it a try. It did save me from a few occasions, but the stuttering of the windshield wiper was not expected. Quote:

This model has had its share of issues
Much as I love my early production 3.0i version there have been a number of Z4 issues with this model that have impacted its quality score:
1. The M40i had stones get stuck in the brake hardware causing grinding or squealing issues 2. The wireless charging pad in all of the cars has given everyone phone overheating problems and it doesnt really charge well either 3. My entire infotainment system didnt work right from day 1 and took 1 year for the dealer to fix. Carplay didn't work right, my head unit was crashing at least once every trip, the car didn't sense my key and when I opened the trunk and the alarm went off about 25% of the time. 4. One of the gaskets fell out of the front distance sensor in the bumper 5. Finally there were little rubber stops in the convertible top that contacted the A pillar to make the top seat properly. Both fell out of my car and the dealer had to replace them both. Not big things but not things you would see on a Toyota product. Mechanically the car has been very good. Id say that 90% of my reliability issues were software related which was finally fixed by a new OS reflash this summer. Quote:

The control unit for the convertible roof on my Z4 failed this past summer and it took over 6 weeks for the replacement to arrive from Germany.
Still missing my Z4.. Rob |

Yikes.
I'm still very surprised that the Germans have such quality issues compared to the Japanese. I worked for a German company for a while and they are the most incredible engineers and hard workers. Not sure why the build quality isn't as good. But this stuff isn't anecdotal. Everyone I know who has owned a German car of any kind has had it in the shop for a significant amount of time for many different things. Of the seven Japanese cars I've owned, only one has broken down and left me stranded and none of them needed a repair before 100,000 miles. That's incredible. Oh well, that's what warranties are for. |
