In this case, does lemon law still applies? Say they tried to fix for a 2nd time still failed, then a 3rd time still failed, lemon law should be valid then. But, in your case, the car rear bump was damaged previously, although not sure about if it is directly linked to this issue… but…, complicated.

Good luck to you, hope they fix it this time.

Edit: July 17th and I've been without the vehicle for 10 days now. Not a peep from the dealership and the car sat all day on their lot. Meanwhile, I keep driving their X3 30i loaner.

Edit: July 18th. 11 days and the car has been sitting in the dealership compound for 2 days now.

There are no lemon laws here in Canada. There is CAMVAP which is an arbitration board, but BMW is not a member of it.

The bumper was replaced (not repaired) and repainted. However the issue was happening prior to that, just less frequently. So I think it is safe to rule out the bumper.

I'll just have to wait and see what happens next week. I really don't like driving the car now since I have no idea when it will decide to swerve left. Turning off the feature is not an option since I paid for it.

Edit: Read the article about the frontal collision defect. Totally unbelievable and a I hope I'm not in store for the same type of treatment from BMW if the problem persists!

Wishing I still had my X6.

July 20th and it's now 13 days in the shop. I stopped by the dealership today and was told that the tech wants to replace the front right radar sensor, but is waiting for BMW approval. BMW (not the dealership) is dragging their ass on this. They asked if I wanted the car back until then, but I declined and will still drive the X3 loaner.

I think this is where I start getting a bit more concerned and have to be careful how I proceed. Whatever happened to a timely repair of a vehicle because 2 weeks is starting to push the limit of my patience. I think taking the car back could be bad if all of a sudden BMW says I accepted the car back so I must have been ok with how it is working. I'm going to have to do my homework now to prepare for the possible outcome that BMW is going to say the car is operating normally and collision sensors may be succeptible to outside interference. We all know that's BS, especially when it's now happening every single day.

There's no lemon laws here in Canada and BMW isn't even a member of CAMVAP. I really do just want the car fixed.

Do not ever accept the car back without complete fix. Do not give them any excuses to waive repair/ delay the repair.

I recall there is a time threshold to automatically trigger lemon law in US, but has to be continuous time period. Yes, you mentioned no lemon law in Canada. But my point is the longer they have your car, you should be more strengthened legally or sort of.

Have you asked the dealer to setup an appt for you to meet the BMW after sales rep? This person works for BMW Canada and visits dealers 2-3 times per month (depending on market size). They may be able to assist you better once you have a face to face meeting to discuss your concerns.

I have not, but I will wait until next week to see what happens. I am not confident that replacing the right front radar sensor will fix the problem.

There has to be action next week to finish repair. The car just can't keep sitting at the dealership like it currently is.

Rob

[Bulent Ali]

Yes. Do not accept th car with the fault . This is a safety issue on behalf of BMW. If no fix I'd ask for my legal rights...maybe replace car with like to like . Hang on !

Rob,

Just catching up on the thread and just am totally blown away at what an absolute shit show the issue has become. As posted when you 1st started the thread my 2020 M850i coupe has thrown the warnings a couple of times (irony always in the right side) but in each occurrence there was a lane next to me and in traffic so assuming they were legitimate with another car getting too close on the right side. This is part of the Driving Assistance rear cross collision function. There to help when another vehicle gets too close not to trigger BS alerts all the time and steer the car in the opposite direction from the collision warning side.

Absolutely keep the loaner and as others mentioned it may indeed be the paint job on the bumper especially now that the dealer has replaced the right rear sensor. There are even Individual factor paint colors that if chosen the function will be coded out. I've always assumed that due to BMW not QA'ing every color and how it can potentially negatively effect the sensors. Hopefully, replacing the front right sensor is the final answer as logically all 4 operate in tandem and the front right may have a fault within itself.

In any scenario in which a vehicle is unsafe to drive lemon law or not BMW plus BMW CA should get it into 100% factory specs with the tech working flawlessly or in essence buy the car back (that's how the lemon law works in the US) or offer a full replacement to match the vehicle purchased.

That's exactly how mine was last fall when the car was new. Due to a puncture hole, the bumper got replaced in January, repainted in February/March. PPF got re-added to the rear fender in April?

I think the issue actually started getting worse last December. It was happening once a week. Then in April it was basically once a day.

What I recommend is setting your drive recorder to record 20 seconds before and 20 seconds after, activating by holding the button down. Then any time it does happen, you can get a recording to see if anyone was actually close to you or not.

Thanks and do have those settings on drive recorder just in case of an accident. The issue hasn't happened for months now (6+ easy since the last time). Hence if it happens again I'll try to remember to hard press the camera button to trigger the drive recorder recording. 👍

July 25th, I got the car back today.

Nothing else was done other than the rear right radar was replaced. BMW woulnd't do anything more unless the dealership could verify the problem persists, which the dealership wasn't able to do.

The car was ok on the drive home. Maybe this will be the fix? Time will tell.

There's a small bit of some black rubber type compound reside on the rear bumper. Like left over decal residue, but thick and clumpy. I'll try some goo gone to see if it comes off.

Rob

[Rob_G77]

July 28th. The collision avoidance triggered twice tonight. Once on route to the casino to meet a friend and then later on the way home. The blind spot light came on too.

So come morning I will go to the dealership again and tell them it's not fixed. I don't blame them for this, but I do have to say they can't have the car for another 3 weeks trying to fix it and then it's not fixed. I also don't think replacing the front right radar is going to do anything either.

Have you had a meeting with BMW's regional corporate entity? If not, it's time to demand a meeting at the dealership with that person. And I'd say it's time for the dealership to put you into a comparable vehicle while this situation continues to resolve, at least a 7 series. Good luck man, your situation has reached ridiculous.

It's too late in the week, it will have to wait until next week to see how things are going to progress.

But, I do have some new information which I find to be quite interesting. Someone turned OFF the collision avoidance steering intervention in the driver assist settings. I hate to be a conspiracy theorist, but I hope they didn't do that to help make me think the issue was fixed. It's not the first time I had someone from the service department disable something in the settings.

But, the weird thing is that even with the steering intervention disabled, the steering intervention was still happening!

3am July 28th. 16 seconds in.. watch the headlights go across the center line

Another disappointing update and watched the video to confirm that your empirical data proves sadly nothing has been truly fixed. Granted you're in CA and Im in the US but I seriously doubt either of us can turn off the steering intervention for side collisions. In my iD7 (latest 07/2023.33) I can turn off the warning but not the steering intervention (only if 20 MPH or greater). In other words turn if I turn off the warning I'm pretty sure the car will still kick in the intervention regardless.

For Lane departure warning (40 MPH plus) one can tune how far you need to be from either lane marker before it kicks in plus turn off the steering assistance all together. I've played with early, medium (the default) and reduced and ended up back with medium and the intervention in play. Although I don't text and drive, etc. there are the rare occasions in which I get a Teams chat message from work that does require some sort of response. The lane departure control in those scenarios has been very beneficial.

[Rob_G77]

You're correct and I made a mistake. Someone at the delership turned off the side collision warning. It seems strange that you are not allowed to disable side collision steering intervention, only the warning.

Anyhow, according to the documentation I can find, the side mirror light will also blink as a warning which then doesn't necessarily mean the car is behind you.

Perhaps they should also replace the front radar sensor then after all.

It is odd that the warning can be disabled but not the steering intervention. I'm guessing that is that comes down to liability on BMW's part and in their best interest regardless of whether you want the warning or not the car will still try to intervene to avoid an accident.

That is also related to the same package but more focused on the BSM (blind spot monitoring). Meaning the car triggering can indeed be on the side and/or behind and the BSM lets you know as at least in my coupe there are plenty of blindspots vs full visibility.

Good question and as stated earlier at least from my understanding the sensors all work in concert as that is how the full driving assistance package keeps the car in the lane.

[BMWGirlFL]

Try turning off lane departure warning/intervention.

My M850i is a 2022 convertible.

Thanks, but this is side collision avoidance which shows a "side collision avoidance" message on the main display along with either the vehicle swerving left or at lower speeds below 30kph the steering wheel vibrates. It appears that only the warning can be disabled, but not the system itself. I've been driving the car for months and months with this issue and it's getting very tiresome!

I'm literally driving the vehicle straight (drive assist enabled or not) and it will suddenly swerve left on it's own accord, blink the right mirror light and show the message on the screen.

It happened again twice tonight, 1 minute apart. These two triggers both caused very abrupt steering swerves.

Back again to the dealership tomorrow. This is dragging on way too long.

It sure spoils the driving experience that a $150k Cdn car can't be fixed in a timely manner and I have to keep driving it the way it is. Especially given the other grief I've had with this thing already.

August 10th........ Not much new. The dealership hasn't followed up with me in over 2 weeks now since I've had the car back. I've been there last week and told them it's not fixed, but they only tell me they are waiting to hear back from BMW.

The collision avoidance message still randomly shows up on the display of course, but steering intervention doesn't always happen (I should check more settings). I believe by default there is no steering intervention below 30kph for collision avoidance. It's 70kph and above for lane keep assist for what it is worth.

Tomorrow I think I will be having a discussion with the service manager about the car and express what my expectations are.

Fix the car. If you cannot fix the car, admit you cannot fix it and then communicate that to BMW for their assessment of the situation. Turning off notification settings is not fixing the car. Waffling on repair by either the dealership or BMW just isn't acceptable. I'm giving them time to fix it and they are just wasting time.

When I'm backing into my garage and not about to hit anything the rear warning will randomly kick in and jerk my car to a stop. I then have to press the accelerator overly hard to overcome it. I keep waiting to back into the rear garage wall because of it. Its completely unpredictable when its going to happen.
