Frontal Collision Warning - Malfunction

[fps]

Thanks for checking in, and I appreciate the support.

After two months of nonsense, the vehicle is finally going to be replaced and hopefully this will all be wrapped up within a week or two. Fortunately, the dealership has been great throughout this entire process, fully supported my complaint, and even identified the right person from KMA to bring into the conversation in order to meaningfully advance the issue and find a path to resolution.

Unfortunately I do not have any information to share about how to actually address a repair of this defect. Mine is apparently the first vehicle in the country where the FCW/A misfire has been replicated at the dealership level, so hopefully KMA will take this unit, strip it down to the frame, and find out precisely what was causing the misfire so that to the extent other vehicles experience a similar problem, a fast and effective repair can be performed.

JMatty, Can you tell me a little more about your system behavior before the unexpected and abrupt activation of the braking system. Did the system often deliver a warning alert., without actually braking in traffic and at what distance from cars in front or to the side did this occur? My system delivers no warning and no active braking when I think it should have at least delivered a warning message. I am concerned that mine is not actually doing anything at all when it should. At what distance from cars in front did you receive a any kind of message or warning? On a previous car I that I have owned, with a similar system installed, it has given me alerts and on occasion actively braked when a car cut me off in traffic. So far my Telluride has given me no warnings or active braking when personally I think i should have. As a result , I"m trying to determine what is normal and what is not. I am going to my dealer tomorrow to have them check it out, but based on the experience level with this new model, I do not expect much. So anything you can tell me to educate me on how your system worked, when it was acting normally would be appreciated. Did it ever work as expected and what were the circumstances? Anyone else out there please feel free to chime in on this and what you have seen with your Telluride as well. I'd really appreciate the knowledge gained from you experiences as well. My system appears to do nothing when I think at least a warning is warranted. To be clear, I'm asking about non cruise control engaged forward collision warning and active braking events.
Any experience from anyone would be greatly appreciated.
Thanks

Morning. I wish I had more detail to share, but what I originally wrote fairly encapsulates my experience.

I didn't experience any episodes of a warning signal without activation of the autonomous assist - every time the audible warning signal and autonomous braking were simultaneous, and it never operated properly in response to an active threat. Fortunately I was never in such a situation.

The first time it occurred was on my first full day of driving and it scared the hell out of me because I didn't know what was happening. It fired twice within about 45 seconds without anything remotely close to the vehicle, and that's from a 360-perspective. By that I mean there were no forward threats, no vehicles, objects in the road or anything else within 75-100 feet minimum. About two days later it fired again at 70ish mph, again without a threat anywhere near the vehicle, and almost resulted in an 18-wheeler pancaking me from behind.

I'm not going to pretend to be educated enough in this field to offer an opinion as to whether your system is operating properly, but understand that KMA is figuring this out as we go along. TechLine work through a fairly generic checklist before doing anything to address a specific vehicle, and it takes an exorbitant amount of time to get a field tech (not an engineer) or an engineer out to a dealership to actually evaluate a specific vehicle.

Best of luck and please keep us all posted.

Loved my Telluride until about 3 weeks ago when it started breaking sporadically for NO reason. It is quite scary as I will be travelling 60 to 70 km an hour and the ccar will apply the breaks randomly. It has happened 5 times today alone and the car was maybe driven for a total of 40 minutes. I am afraid I am going to get rear-ended. As tonight it even braked while I was travelling straight through an intersection. I have noticed that it really doesn't like me in the lane beside the turn lane when there is a car waiting to turn. I have turned off lane assist and the adaptive cruise and to no avail. As we were driving it to the dealership tonight (in two cars) , I was making a right turn and slowing down to turn when it aggressively applied the brakes without warning. I pulled over and asked my husband to switch cars as I was done with driving this unpredictable vehicle. He wasn't driving for more than 3 minutes when it did it two more times to him. I now have a 3 month old car that I am worried about driving. We were supposed to go on an out of town trip on the weekend and I had to leave the Telluride at home. I don't want to know if it would also brake randomly on a major highway. I hope Kia can fix my car and solve this major issue before any gets hurt. Any advice would be greatly appreciated.

I loved my Telluride for the first two months, now my tune has drastically changed over the last two weeks. The vehicle is randomly breaking on me and putting me in dangerous situations. When travelling about 50-70 km an hour the vehicle will randomly apply the brakes without warning. I have turned off lane assist and cruise control, but it continues to happen. Today alone with about 40 minutes of driving it happened 5 times. On the way to the dealership to drop it off, I pulled over and switched cars with my husband after it once again braked without any reason. My husband only had to drive for about 3 minutes before it happened to him and once again in the additional 10 minutes to the dealership. I see above in this thread that I am not the only one. This is a serious issue that Kia needs to fix immediately before someone gets hurt. It is very scary when travelling in steady traffic and having your brakes applied without your will. There seems to be some pattern to this issue. I know that it will do this just about every time I am travelling at the 60 km range and passing through an intersection where a car in the lane beside me is waiting to turn. Any advice or solutions would be GREATLY appreciated!!!!!

Turn it off until its fixed.. but....very important... it must be turned off every time the car is started because it auto starts on car start up every time. Use the the mode button on the steering wheel to select off on the forward collision avoidance portion. If you think this is the cause then turn it off and go to the dealer for evaluation. If you think it's the cruise control causing this the dont use it and take it in. Just my two cents. Be careful out there..

Is this system on all trims?

 

[blitt]

I believe FCA works regardless if you are using cruise control or not.

You are correct....FCA is "ongoing" at all times.

 

[chrismjto]

My Telluride has been at the dealer for 3 days and now I have a rental. They are hoping to get back to me next week with some news about the braking issues.

That's what I thought too?

 

[Humaid]

It works even if the cruise control is off. It happened to me while driving forward and in reverse as well.

 

[chrismjto]

JMatty your problems sound very similar to the problems I am having. After they had my car for a week, I drove it home and after about a half hour the master warning light came on along with the warning to check the FCA system. Good news the brakes did not randomly engage during my 40 minute drive today, but have no clue what the new warnings are. Do you have any advice for me. This is a 3 month old vehicle. Are you in US or Canada?

I'm US-based (southeast), and sorry for your troubles. I wish I had something more to offer but my vehicle was never repaired. The dealer thinks they were able to resolve the issue by replacing the radar, but neither they nor I am comfortable getting back in that vehicle because there is no explanation for why it fired so far above the supposed operational threshold. I'm simply not willing to take that level of risk when there are other options.

After two and a half months I'm finally in the home stretch of trying to get this resolved with a replacement vehicle. My only advice is to go back to your dealer and make sure that they either identify and specifically correct whatever is causing your misfires, or work with Kia Motors America to replace the vehicle if they can't fix it. I'm fortunate in that my dealer was exceptionally supportive as they were able to replicate the problem I was experiencing and helped navigate through corporate to get the right people involved.

Jumping in a little late, but could have been a wiring harness issue. I had a FCA malfunction warning display, (with NO unintended braking) which turned out to be a wiring harness short. Required a complete main harness replacement. Not sure if that was considered....but FYI, the fix was perfect, and I've had no further issues.

Hi.. do you have any specifics on which wiring harness and specifically where they found the short..this info might help a lot of us with issues. Also as it seems we are all educating the dealers, at least some, this info would be helpful.

Replaced the main engine harness AND the dash harness. Not sure of the exact location of the short. Dealer ordered and replaced both just to be thorough. My issue was similar to Crismjto's second (issue). I only had the car for a few weeks, there was no random braking. They actually identified a short pretty easily. KOA would not allow them to trace and repair and insisted on a full harness replacement. I was very leery of messing with that main harness but the car has been perfect, no issues, so all good. Crismjto...maybe pass this (possible short) along to your service writer. Dealer was Earnhart Kia in Phoenix. They were excellent. Jason White was the service writer.

 

[chrismjto]

Thanks for your advice. I am in Canada and not sure if the process in these situations is the same. I will pass this info to our Kia dealer about the harnesses. Unfortunately, it seems that they just don't know at this point what the problem is. I handed in the car last Tuesday, and only had my car for a hour last night before the problems started again. We returned it to the dealership again today. I'll keep you updated. Thanks again for sharing

 

[chrismjto]

Update....my braking issue has now also been replicated at the dealer level.

[chrismjto]

Did anyone have a dash cam in their Telluride when the vehicle was braking spontaneously?
They are thinking the braking may be caused by dash cam interfering with the radar in the car?
They are also looking at the placement of my license plate. I have now been without my car for over a week except for a couple of hours before I returned it again.

Sorry you are still experiencing this, but good to know that you'll have support.

No dash cam for me, and we don't have front license plates in NC.

Thanks for responding. I feel at this point, Kia is hoping to find an easy solution to the problem. I think there is more to it. Even if a dashcam could affect the car is this way, that would be very dangerous for drivers.

 

[chrismjto]

It happened again without a dash cam set up. I wonder JMatty if Kia has figured out what was going on with your vehicle yet, as you are further along in the process than we are.
