TPMS problem with the 2020 XCeed 2 model.

[Rojoires]

I am now experiencing a problem with the TPMS sensor on my just purchased 2020 Kia XCeed, which occurred within the last two months.

The TPMS warning is activated. Subsequently, I bring the car back to its place of origin and allow it to remain there overnight, allowing the tyres to reach a lower temperature. After the car has cooled down, I check the tyre pressures and confirm that they are all accurate. Subsequently, I use the TPMS button inside the vehicle to recalibrate the tyre pressures, doing this by maintaining pressure on the button for a duration of 3 seconds, so eliminating the alert. However, usually after 5-10 minutes of starting my next drive, the TPMS alert reappears. I have performed this procedure an indeterminate number of times!

Thus far, I have returned the car to the dealership from whom I made the purchase, as well as to a nearby Kia dealership. Both individuals have been unsuccessful in resolving the problem and are uncertain about the appropriate solution. The technician at the Kia store said that a potential reason of the issue might be an inconsistency in the tread depth of the two rear tyres. Specifically, one of the rear tyres has a tread depth of 5mm, while the other three tyres have a tread depth of 7mm. He suggested that I consider replacing the two rear tyres, stating that it "could potentially resolve the issue."

Has anybody encountered this problem and identified its root cause? I am hesitant to spend over £200 on purchasing two new rear tyres, especially considering that it is only speculative that this action would resolve the problem.

Thank you in advance for any assistance.

The vehicle you purchased is currently covered by the warranty provided by the dealership. If they are certain that new tyres are necessary to address the issue, they must install them.

Kindly return the issue to the dealer and request a temporary vehicle until they rectify the problem.

It is unlikely that the guarantee for a vehicle of this age would cover the tyres. The tyre with a tread depth of 7mm may have been replaced due to a puncture, which might explain the mismatch. It is recommended to replace the tyre when the tread depth reaches 3mm, since a tread depth of 7mm is near to that of a new tyre.

While it is possible that the statement is accurate, it is important to note that the original poster (OP) just purchased the vehicle only two months ago. As the automobile is experiencing a defect, it is the responsibility of the dealer to rectify the issue under the warranty agreement. If the dealer claims that the problem is due to the tyres, they must replace them accordingly.

The car was not purchased from an authorised Kia dealership. Uncertain whether this is anything that would be covered by the Kia warranty.

The significance of the matter is really negligible. According to the current legislation, namely the sale of goods statute, any defect found in a second-hand vehicle during the first 6 months is considered to have existed at the time of purchase. The TPMS problem has shown itself after a period of 2 months, therefore making it the dealer's obligation to rectify the issue. I acknowledge that there may be significant resistance from the dealer about the installation of two new tyres, which may need some discussion and compromise. However, my main contention is that it is the dealer's responsibility to identify the issue and provide a resolution.

These TPMS (Tyre Pressure Monitoring Systems) operate based on rotational data.
Upon detecting a disparity in rotation.

I would recommend replacing the rear tyres with new ones, preferably a matching pair.

Thank you everyone.

I am attempting to communicate with the dealer who sold me the car in order to persuade them to assume responsibility for the expenses associated with repairing it, or alternatively, to do the repairs themselves. However, I am also seeking assistance here to see whether anybody else has encountered a similar situation and is aware of the appropriate solution. Optimally, the goal is to resolve the issue efficiently and expeditiously for all parties concerned.

The dealer from where the car was purchased seems to lack the expertise to repair it, since they are not an authorised Kia dealership. The Kia shop in my area, which is unconnected to the issue at hand, recommended replacing the back tyres. However, I was dissatisfied by the dealer's lack of certainty over whether this would resolve the problem.

If anybody has encountered this problem and discovered a solution, it would greatly benefit me to have the ability to guide the dealer towards the appropriate course of action. Seeking to minimise recurring trips to several garages without achieving any repairs.

As previously mentioned, and as can be seen in other discussions on TPMS, this particular form of TPMS detects variations in rotational speed among the wheels. The concept is that if one tyre has lower pressure compared to the others, it will possess a smaller circumference, resulting in a quicker rotation than the others. As previously said, it is possible that tyres with varying tread depths may lead to the TPMS system inaccurately detecting low tyre pressure. This is likely the reason why one garage has recommended purchasing two new tyres. However, it is important to note that this solution may not necessarily fix the issue at hand.

I possess little knowledge with TPMS systems. Does it provide specific information about the problematic tyre or only indicate the presence of a problem with one of the wheels? If it specifies the particular wheel with a 5mm tread, it is fair to assume that this is the basis for its difference from the other three wheels. If such is the case, you may consider adding an additional 10 psi to the tyre, which would result in an increase in its diameter. However, I am uncertain about the exact magnitude of this increase.  to determine whether it has any discernible impact, albeit it is a very speculative endeavour

The term "indirect" alone indicates a state of being at a low level. Therefore, it is necessary to examine each and every one of them.
In contrast to the Direct method, which provides individual pressure readings for each wheel.

I agree that the selling dealer should handle the transaction.
However, my concern is that they may only replace one of the tyres with a used one to make it resemble the others.
