Electrical Short In Battery Of Kia Soul EVs

Posted on by

Kia will be contacting owners of certain 2015-2019 Kia Soul EVs about a problem that could result in a short circuit in the high voltage battery pack and a potential vehicle fire.

Kia first became aware of the problem in May 2022 when they received reports of smoke from the battery vents located under the passenger seat on a 2017 Kia Soul EV. Kia records showed that the vehicle’s high-voltage battery had been previously replaced under warranty. In October Kia received a second report, involving a 2018 Soul EV. The customer reported the smell of smoke just before the vehicle stalled. Kia performed CT scans and a tear-down analysis for both vehicles but the results were inconclusive due to thermal damage and water intrusion from fire suppression.

As Kia investigated the first two reports they received a third customer complaint of popping noises and smoke coming from the cup holders of a 2018 Soul EV in Hawaii. Kia and the battery supplier inspect vehicle #3 and performed a tear down analysis which found the heat damage was limited to the battery case assembly. The preliminary investigation results were inconclusive and the battery was shipped to the manufacturer for further analysis.

According to the defect report, an electrical short between the anode and cathode of the battery cells can occur with the high-voltage battery pack assembly case. The cause of the electrical short circuit is unknown but believed to be caused by abnormally excessive precipitate within the battery cells.

Although the cause of the electrical short circuit is unknown, Kia has decided to recall all 2018-2019MY Soul EV vehicles equipped with an E400 battery and certain 2015-2017MY Soul EV vehicles that had the high voltage battery replaced under warranty with E400 battery.

Dealers will update the battery management system software with new software that will illuminate the EV warning light, limit charging capacity, and reduce vehicle power if an abnormal voltage is detected. If this occurs, the battery will be replaced. Owner notification letters are expected to be mailed on May 26, 2023. Kia’s number for this recall is SC267 and the NHTSA campaign number is 23V-218.

There have been three (3) thermal incidents limited to the battery case assembly with no injuries, no crashes, and no fatalities.

Posted on by

Automobile manufacturers Porsche and Bentley Motors will be contacting the owners of certain 2017-2021 model vehicles because of a problem with the external coolant pump in the climate control system of their vehicles.

Porsche became aware of this problem at the end of December 2022, when they were contacted by their coolant pump manufacturer about a potential malfunction of the electric external coolant pump used in the climate control system. An investigation was opened and Porsche reviewed whether there were any possible common influences that could have contributed to the problem. (e.g. Extreme Temperatures, A Corrosive Medium, Special Driving/Customer Behavior, etc.) In January, Porsche determined a safety defect existed and decided to recall the subject vehicles. During this time, Porsche informed Bentley of their investigation because certain Continental GT and GTC vehicles were manufactured with the same pump.

The vehicles affected include:

2020 Bentley Continental GT
2020 Bentley Continental GTC
2017-2021 Porsche Panamera
2017-2021 Porsche Panamera 4
2017-2021 Porsche Panamera GTS
2017-2021 Porsche Panamera Turbo

According to the defect report, some 2017-2021 Porsche Panemera and 2020 Bentley Continental vehicles may have been manufactured with an electric climate control coolant pump that could experience humidity ingress. The humidity could cause a short circuit and, in some instances, thermal damage to the external coolant pump. In rare circumstances, the thermal damage to the harness could progress into a fire.

On the affected vehicles, vehicle occupants may notice an issue with the Climate Control system or reduced performance when using the Residual Heat function. (This allows the vehicle to be heated after the ignition has been switched off, using the remaining heat in a warm engine). On vehicles fitted with a W12 engine, an Engine Management Light could also illuminate.

Dealers will replace the external coolant pump and will inspect and replace the plug-in connection, as necessary.
Porsche’s number for this recall is APA1and the NHTSA campaign number is 23V-033
Bentley’s number for this recall is RE23/02 (RC67) and the NHTSA campaign number is 23V-034.
