Consumer Reports bashes 2016 Genesis

[Mark_888]

I did not know this was widespread. Not sure if I ever reported this to the forum but on my test drive I loved everything but the vibration when braking. They did a "very slight" turning of the front rotors to remove rust build up and then I took it on an extensive test drive, no issue whatsoever with the brakes, same since buying. Car sat on the lot for almost 1 year so explanation seemed reasonable.

Maybe sitting on the lot was the problem, I don't know. Up until the 2015 models, no one on this forum ever mentioned warped rotors (with symptom of pulsating brakes). I don't know if it is "widespread" but I have seen at least a dozen people mention it on this forum, so doesn't appear to be an isolated incident. Overall, the Genesis has excellent brakes if the rotors are not warped.

This is not unusual at all - I leased a new Ford Taurus - five miles down the road - it was obvious that the front rotors were loaded with rust.

Took it back to the dealer.

After the usual lying, delays, and evasion, they cut off a few thousandths from the front rotors - and I was on my way back home. Problem solved.

My brake problems were related solely to rust on the rotors from not moving the vehicle on a regular basis while on the lot. You could see the rust everywhere but where the pads sat on the rotor for months. Turning the rotors took care of the pulse/vibration. There was no reason for the wheels to be remove/replaced during transit, so it was not related to this in the ports.

Whatever caused it, there were enough instances of it that the CR statistical survey picked it up as the brakes having an above average number of problems. Like all such surveys, it is hard to assess how serious it is, and in this case may only affect brand new cars sitting at port of entry for an extended period of time.

One thing I do like about the CR ratings is that they distinguish between major and minor problems for the engine and transmission.

Brake rotors do not warp, they accumulate brake shoe deposit or rust unevenly with infrequent use especially where the brake pad sits and causes the pedal to pulsate due to resulting variable thickness/friction on the rotor surface which has been coined as warpage but believe me, rotors do not warp. Here is a good read on the subject. http://www.stoptech.com/technical-support/technical-white-papers/-warped-brake-disc-and-other-myths

My 2 cents. The 2016's sat on the dealer lots for a hell of a long time. They had to discount them severely with up to $10,000 to get rid of them and many still remain yet continue to sit and rust as time goes on. IMHO, rust on the rotors and incompetent dealer prep which should have included a light resurfacing before delivery is at fault.

Thank you. Nice article pertaining to high performance brakes. A majority of complaints for brake pulsation on new cars are related to pad imprinting and corrosion, but one cannot argue with a runout gauge. Disk rotors can warp when the lug nuts are not properly torqued.

I'm sorry Midnightsun but I must disagree with your statements. It is true that rotors do not warp if installed correctly. However if they are not installed correctly, they may warp. I was in the auto repair business for many years. I have personally checked and resurfaced many rotors that were warped. When I put rotors on the machine, I would check to make sure the rotors were truly warped and by how much to make sure they would still be serviceable. If they were too thin then they had to be replaced.

When I got my 2016 Genesis it had the brake shutter problem. I knew that it could be from rust so I just drove it for about 200 miles and the problem didn't go away. Before taking it back to the dealer I desided I would go ahead and get rid of those silly wheel lock lugs. In doing so, I discovered the wheel lock lug nuts were tightened way too tight while all the normal lug nuts were correctly torqued. Using a torque wrench I found that one of the lock nuts required over 200 ft lbs to brake loose. I didn't check the rest of the lock nuts but I know they were too tight. I re-torqued all the lug nuts, drove the car and it was much better. Then after a few hot/cold cycles, the problem was gone.

I don't think the wheel lock nuts were installed at the factory, but some time between leaving the factory and delivery to me. The removed lug nuts were in the trunk in the package the lock nuts came in along with the key (thats what I call it) to remove the locks.

Another factor for 2015 and perhaps some early 2016s was the change in tires due to the Hankook recall.
All of the cars that were in transit were changed in port, or at the dealership. Do you think those were all properly torqued?
