Is anyone else experiencing brake squeal? I get it regularly when applying the brakes at low speed such as when I leave the parking garage. Fisker says this is normal due to the regenerative braking and high performance brakes. I've never experienced this in my Volt with regenerative braking or my R8 with high performance brakes. It's rather aggravating from such an expensive car.

I'm experiencing this issue too. It's worse in cold weather and it gets less when the brakes warm up. How cold is it where you are?

My dealer told me that a lot of the Karma's they deliver have this problem. They've also experienced it on some Aston Martins in the past. I hope they can find a solution for this. It's a sound that doesn't befit a car like the Karma. All those people not already staring at the car will definitely look when ist squeals. I'm now even trying to use Hill Mode 2 as much as possible to avoid braking.

I've had 2 cars in the last couple of years which had major brake squeal. The first was a Mercedes CLS55 AMG and the last one was a Porsche Panamera Turbo. Both of these cars are more expensive than the Karma so I don't think high end cars are immune to brake squeal.

And with both instances I was told the exact same thing from the service departments: nothing you can do about it. Many times it just goes away after you rub through certain areas of the brake pads. But it could stay. Both service departments were also happy to put it down in my service complaints for the mechanics to look at. And both times they would "clean the brakes" and put some kind of lubricant that I was told may work temporarily. It did, and the squeal came back.

Since I heard the exact same thing from 2 high end car service departments (MB and Porsche) I just assumed it was true.

I was told that ceramic brakes were an option on the Porsche (major $$$) and then you would not have any squealing.

Yes, mine do it a lot when it's damp out, but it mostly goes away after 5 minutes of driving. High performance brakes like the Brembo's have a tendency to do that, unfortunately.

Brake squeal has been very bad on my GTR since day one when the brakes are cold. No fix according to the dealer. it may not be a coincidence that the GTR like the Karma has high performance Brembo brakes

Mine did the same thing, especially in cold or wet weather. Kind of embarrassing. I guess it is like farting, it is normal to fart, everyone does it, some do it quietly ;-)

It's dry and warm here in Southern California. The noise does not go away after a few minutes of driving. My wife drove home from work which is about 45 minutes away. When she opened the garage door to park I thought she traded the Karma for an old school bus. The brembos on my R8 never squeal.
Fisker suggests more aggressive braking to help eliminate the noise. I might have to look into other pad compounds if this can't be fixed by the dealer.

My car is at the dealer this weekend for an update to software version 6.14 (which will probably get the green light on Monday). They also looked at the brakes and said they greased them to try and solve the problem. Let's hope that does the trick.

Other updates: adjustment of the rear window (which was causing some wind turbulence), better grounding, adjustments to the heat shield around the exhausts, and a small modification to the exhausts which should solve some of the noise in Sport Mode. They made the connection between the exhausts and the engine more flexible, so it resounds less.

LOL. Literally.[hr]
I haven't experienced this and I've been driving with the radio off. SoCal weather the two weekends I drove my car (about 350 miles and counting) were in the mid-50s, and it rained one weekend. I generally have been driving in Sport mode in Hill 1 and sometimes Hill 2. In most flat areas, I still keep the car in Hill 1.

I've only had it happen once and right after I washed my baby. It literally was just one instance and hasn't happened since. I have nearly 800 miles on it after nearly one month of driving. It is obviously not a universal issue.

My dealer greased the brakes (the blocks) this weekend and since then I've not heard the brakes squeal anymore, even though it was pretty cold outside (-15 Celcius, 5 Fahrenheit). Before it was pretty bad. So it does look like this problem can be solved. Hopefully the effect of the grease holds up. The dealer said it is high-grade grease which should solve the problem permanently.

I know Audi isn't immune. I know an owner of an R8 and another of an S4 and they both experience it. In both cases, it's worse in cold weather. The S4 is amazingly loud. In both cases, a couple of rounds of hard braking (think 60mph to a full stop) to warm up the brakes typically reduces the noise significantly. I also had the same problem in my SL600, but hard braking wasn't has helpful (nor was my noise as loud as the Audis...)

Whenever my Karma starts squealing the quick fix is just to hit the brakes hard. That cures it every time. That's the usual cure for most brake squeal. Mechanics will always tell you to go fast and slam the brakes all the way, and that'll usually do it.

With the Karma, I hardly ever hit the brakes at all and when I do it's very lightly, so a good brake slam every now and then cleans them up and removes any moisture on them causing the squealing.
