Automatic hold transmitting torque to wheels in Drive mode

[p00rmansp0rsche]

Greetings everyone,

I brought my Sorento to Bolton Kia on Friday for its fourth-year service and enquired with a technician if the car should transmit torque to the wheels when in Drive and on Auto Hold.
He said that it should function as if the clutch is engaged in a manual vehicle. He took it for a test drive to verify this and returned affirming that he saw it performing as I described. He expressed his belief that it should not behave that way, although he was unable to provide any more clarification.

Does anybody else's vehicle exhibit similar behaviour? When observing the display indicating the four wheels, activate Auto Hold in Drive (D). Does the display indicate orange for the wheels? When shifted into neutral, does the vehicle "relax" when the clutches disengage and the display transitions from orange to grey?

I am eager to get input about the car's problem with warped brake discs, as I suspect that the brake system's excessive clamping force to stop a vehicle under torque is the cause of the brake failure. They are attempting to mislead me by suggesting it may be a wheel balance problem; nevertheless, the wobble manifests just while braking.

Thank you very much

I do not own a comparable vehicle, since I have now departed from the stable and acquired a Ford. What does it indicate when the foot brake is engaged? Are the clutches disengaged? Consequently, Auto Hold should logically be same. I cannot see any correlation with deformed discs.

I will verify; I recall seeing identical conduct prior to the replacement of my herniated discs, with no recurrence in recent years.

The brake geometry is affected by the callipers' movement; in my experience, Kia dealers often fail to execute this correctly, resulting in the typical Kia brake squeal, despite the tolerances being specified in the technical documentation.

Wheel balancing is a humorous explanation that only Bolton could devise.

Could you please test the automobile at full lock from a stationary position? In all directions, including the reverse. Are there any unusual behaviours?

I recently tested it on a 2019 model.

As you mentioned, it maintains three bars with auto hold and does not decrease.

Engaging the brakes will reduce speed to zero in around three seconds. With auto hold activated and off.

In my opinion, this is a persistent logical fallacy; I recall someone on the forum noting long ago that Kia advised the simultaneous use of both the brake and auto hold functions. (Rendering the auto hold superfluous, amusingly).

It is essential to remember that the orange bars represent only the "predictive" values; they do not constitute an actual 4x4 system.

If you are consistently warping discs, I recommend doing a thorough bedding-in process (which is more difficult than it seems) and developing the habit of lifting the pads before coming to a full stop. I believe a Kia dealer would be somewhat unassisting in this matter.

Thank you for your recommendations. I would want to test them, but regrettably, Kia Bolton still has my vehicle.
They were expected to replace the alarm control module, which was proved malfunctioning by diagnostic code reading; nevertheless, they failed to order the replacement for me.
They may well be "Europe's foremost Kia dealer" in terms of sales volume or profit, although their after-sales service is utterly inadequate.

Do you believe it would be beneficial to contact Kia UK directly?

[p00rmansp0rsche]

I regret to inform you that I have yet to get my automobile. I have been without my automobile for 10 days, including the day of servicing, with no indication of its return.
I have received a new Sportage, which is pleasant; nevertheless, it is a PHEV and its fuel efficiency is poor. When maintaining a speed of 60mph to 65mph when passing trucks, my Sorento achieves 42 mpg throughout my commute to the office; nevertheless, I only earn 37 mpg in this allegedly eco-friendly vehicle. The radar-guided cruise control cannot be deactivated.

[BenTrevor]

Why have they not finished a fourth service in ten days?

[p00rmansp0rsche]

The service was done on schedule; however, they were supposed to replace the defective alarm module while in possession of the vehicle, but it was revealed that they had not ordered the replacement component. Consequently, they opted to retain my vehicle until a replacement could be procured. While it is present, I hope they are addressing the brake problem as well. However, I lack optimism.

Attention, everyone, are we all seated comfortably?
Kia Bolton spent a week hypothesising that the wheel wobbling, which occurred only when braking, was due to improper wheel balancing. I expressed my disagreement in writing. I said that I would not pay for the wheel balancing until it was determined to be the reason, since tire balance problems manifest when driving at speed, not while braking.
Kia Bolton took two weeks to return this morning and provide images indicating that all four of my wheels were improperly balanced (strange, since the vehicle operates very smoothly at high speeds). Consequently, I reiterated in writing, "Please balance the wheels." I will pay for it only if it resolves the issue, which it will not. If it fails to do so, you should continue seeking a resolution. Or similar phrasing.
The workshop foreman subsequently contacted me, stating that they had balanced all four wheels, although the wobble persists at the front, occurring just while braking. Fan my forehead.
He further states, "the wheel balancing incurs a charge as it was necessary to eliminate it as a possibility." This individual is really exceptional.
He states that although the vehicle indicates torque being sent to the wheels when stationary, no fault codes can be identified, and "neither has my master technician been able to replicate the issue." He asserts that he cannot attribute the issue to the use of Pagid discs and pads, as they are a reputable brand. Furthermore, he dismisses the possibility of the callipers being at fault or the car's attempt to rotate its wheels. The brakes are designed to impede this rotation through friction, which generates heat; this heat can subsequently cause metal, including brake discs, to melt. It cannot be that... He states, "I believe we are your local dealer; however, you might consider visiting Perry's in Preston or Acorn in Warrington."
He then asked that I return his courtesy vehicle that day (I'd been out celebrating my birthday with my wife, so no way I could drive!!). In summary, we have received your £450 for the service, thank you, however we have not addressed any issues that might be covered under warranty, and we suggest you take your vehicle to another dealer.
Complete disarray.

An email to CEO Paul Philpott [[email protected]] is warranted to address the subpar service from one of their licensed dealers.
