Hey guys,

I just changed my 2014 535i which handled perfectly to a new 2016 with the same packages ( Msport, premium, exec) and when I'm cornering through a curved road at a relatively high speed(such as highway ramps), it feels as if the back wheels are moving around in the corner even though they are perfectly planted to the ground. It gives a sensation as if the suspension or tires are moving back and forth through the corner, taking all the joy from the car and making me a bit scared to even push it.

I have checked the tire pressures and they seem to be as factory recommended.

Anyone know if this is normal or whether there is something wrong? I have an appointment near October time, and it is really pissing me off.

That's unusual for sure, especially they way you're describing it, sensation of moving back and forth. With OEM run flat tires, car may hop a bit over bumps when cornering fast. It can feel a bit unsettling, but not quite as what you're describing. Once I switched away from run flats car is dead still in corners, some body roll but no "wobbling" or hopping over bumps. You said you checked your tire pressures, so coming to the limit of folding the tire is likely out of question.

Car is not new to you, you know it well since you already owned one, trust your instinct and make sure they investigate it well, curious what you find though.

Has it had new tyres on a single axcel?

I find that new tyres on one axel can ruin the handling on a BMW, as one axel suddenly grips better than the other.

Found this out years ago when I went into a BMW dealer saying my cars suspension was broken, first question my SA asked was whether I had new tyres...

Nope, picked up the car new with 150 miles on it. So i doubt it.

Have you checked the alignment?

I guess it's a trip to the dealer otherwise...

Hmm in my 535i i do get the feeling it is not as planted on highway ramps going 75 to 90 mph. I read it is the front sway bar. Not sure if its the same feeling you are having though. Ive read many threads of people swapping their sway bars for the M5 ones because they are thicker. Some say it is a noticeable difference. I have yet to try it out only because i dont want to have any issues with my warranty. I apologize in advance if this helped you in no way!

Same tires (brand and model) on both cars?

Some early 2014 5 series Msport did not come with the 704 sport suspension. I believe July and most August 2013 builds. Was your 2014 one of these cars? If so, can explain a bit why cars feels different.

Are all 5 wheel lugs in place and are they tight?

One thing that comes to mind is if the dealer forgot to remove the shipping blocks from suspension.

[SonicEndeavor]

The standard passive suspension is pretty floaty in corners, but since you have the MSport suspension, the car should feel solid and smooth through the corners, Definitely get the suspension checked out to make sure everything is tight and that the shipping blocks were all removed (unlikely, but it happens).

Just a thought but have you looked at a VIN decoder to see if the M Sport suspension was deleted on your car. I know that in the UK you can order an M Sport but revert the suspension back to a standard set up....

Yeah, Same tires brand + model.

Both my cars were AWD so you couldn't spec the 704 Suspension, Atleast not in Canada.

I have an appointment with the dealership to see whats wrong with the car but its at the end of septermber The car handles completely garbagely so the wait is killing me!

Ahh your post didn't mention X drive... Good luck with your appointment, why such a long wait!

Both dealerships in my city are at temporary locations as they are expanding their main location, so they have smaller garages to be able to service cars

And neither is really all that good if we're honest.

Attention to detail is lacking, you'll have to do lots of convincing, initial response will be "We feel it drives just fine". I absolutely love the car, but every time I have to deal with these guys I feel the need to take blood pressure meds first. Good luck.

I find that yes on bad surfaces when cornering on tighter corners at highish , it can "skip". Feels rather odd and although I'm no engineer, I suspect its the run flat tyres as I've never experienced this effect on any other car I've had. (This is my first with RFT)

[Bmw doubles]

Upgrade your rear sway bar to the 550 it changes the car even with run flats.

[corys530]

My 2012 535 skips around on the fwy at anything over 75
here in Cali the fwy has those grooves for rain
i attribute it to RFT also..... only a few more miles to the PSS!!!

The floaty/wobbly feel seems normal for the F10. Electronic steering paired with a suspension that is too soft for a car that weighs too much doesn't exactly equate to a nimble track rat.

While base suspension can feel soft at times, OP's saying that he's replaced 2014 with 2016 with identical packages, and new one behaves differently.
I'm guessing he'd know how F10 (soft or not) handles already and is struggling to explain the difference between the two.

Sometime I even think my old 2014 had issues and maybe this 2016 is how it is supposed to handle? My 2014 always had stiff and direct steering no matter what mode it was in, but the 2016 has extremely light steering even in sport+. The suspension was always quite firm and reassuring in all 3 modes, as apposed to now where the car feels overly bouncy at highway cruising speeds and taking 80km/h highway ramps at 120km/h feels like your car suspension is rocking back and forth so much in corners you feel as if the cars either going to lose grip or flip if you go any faster.

Hopefully my appointment on the 26th will address these issues. Just to make sure I'm just not imagining things, I'll request to retest drive my old car that i traded in to make sure I'm not going crazy.

You've confused me now completely.
Hopefully you can get it sorted out at the dealership.
I think we're in the same city, based on your previous 'temporary locations for local dealership' comments.

Speed limits, safety and legal issues aside - you know best what works for you. There are ramps in the city that should never be taken at 120km/hr or more, and then they are those that you could (in theory) take at 120km/hr+ in pretty much any car, so depends what you're trying to do here.

For example if you're taking something like St. Laurent, Merivale, Eagleson or Terry Fox (westbound) at 120+, in my opinion, that's just asking for trouble, even in much lighter and sportier car. But if for example, you're taking Terry Fox, Eagleson or Moodie (eastbound) at high speed F10 wouldn't/shouldn't feel off balance at all.

My favorite ramp is the 417 westbound merging onto the 416 South. Usual speeds taken there was 140-150 in the past . This car, max it theoretically can do is around 120ish before feels like the car isn't confidence inspiring.

Anything but confidence inspiring ride in F10 on that particular stretch makes no sense. I was just there this morning, and one going towards 417 is a bit bumpy, so run flats could in theory "hop" a bit. Other than that, these cars should be able to go "fast" on that particular stretch of the road (both ways) and stay perfectly planted.
