Recall ~ MHEV in US
Not Defender but worth noting.

"2020 Land Rover Discovery Sport, Range Rover Evoque MHEV Recalled Stateside Over Electrical Failure

If you own a 2020 Land Rover Discovery Sport or a Range Rover Evoque equipped with a mild-hybrid system, then it is likely that you will have to take it back to the dealer for repairs, as the company has issued a new safety recall.

In the description of the defect, the NHTSA has noted that the Metal Oxide Semiconductor Field Effect Transistor (MOSFET) could fail due to an electrical overload event in the 48-volt system.

This would cause an electrical cascade failure of the DCDC converter, made by Yazaki Europe LTD in the UK, leading to a short-circuit and increasing the risk of fire. In extreme cases, the occupants may notice a burning smell and/or smoke coming into the passenger compartment from the converter. The electrical discharge will be highlighted by the battery warning light in the instrument cluster.

A total of 3,048 vehicles have been included in this recall in the United States and federalized territories, with a 100% estimated defect rate, including 365 units of the Discovery Sport and 2,683 units of the Evoque. All were built between November 2, 2018, and October 2, 2020 and feature the mild-hybrid system.

Land Rover’s authorized technicians will install new software, which is said to mitigate the condition. Reimbursements will not be offered, as the SUVs are still covered by the warranty.

Dealers will be notified this week and the planned owner notification date has been scheduled for December 18. The Land Rover recall number is N503 and they can be reached at 1-800-369-1000."

Interesting that the fix is a software one, so maybe already done to SOTA enabled Defenders without owners knowing.

Can a software tweak do more than just adjust the the timing on when the system kicks in, duration, duty cycle, etc? And if not how is this consistent with type approval or certified emissions for taxation purposes?

Is this just a case of technology being ahead of the legislation or are there any rules governing such changes?

Come on DSL, keep up with us now..........


LR stands to get a £90,000,000 fine because it had, like Ford and BWM, to recall all its delivered Range Rover Evoque and Discovery Sport PHEV’s due to contamination of the Samsung battery packs recently that meant that they could meet this years CO2 emissions limits. I wonder if there is a connection Ino pun intended) beteewn the MHEV energy store and the PHEV’s batteries? Pangea Green D250 90 HSE with Air Suspension, Off-road Pack, Towing Pack, Black Contrast roof , rear recovery eyes, Front bash plate, Classic flaps all round, extended wheel arch kit and a few bits from PowerfulUK Expel Clear Gloss PPF to come

I'm not sure the potential fine, which is a provision made by JLR, is related to the recall itself, but rather the lack of sales of alternatively fuelled vehicles; which in turn is down to it's poor implementation across the various ranges.

The recall might have slowed down production a bit, but I don't think it's anywhere near the major factor(s).

Now in the EU:

"Alert number: A12/01580/20
Product: Passenger car
Name: Range Rover Evoque, Discovery Sport
Company recall code: N503
Production dates: The affected vehicles were manufactured between 25 May 2018 and 2 October 2020.
Type of alert: Serious
Category: Motor vehicles
Brand: Land Rover
Type / number of model: e5*2007/46*1053, e5*2007/46*1056
Counterfeit: NO
Risk type: Fire

An electrical overload in the 48Volt (V) electrical system may cause a failure of the Metal Oxide Semiconductor Field Effect Transistor (MOSFET). This may cause an electrical cascade failure, causing the DCDC convertor to experience an electrical short where the 12V circuit shorts to ground. As a result, smoke from the DCDC converter can be vented into the passenger compartment, and where sufficient oxygen exists, a sustained vehicle fire may occur. /

Measures taken by economic operators: Recall of the product from end users (By: Manufacturer)
Description: 2019 and 2020 model year Range Rover Evoque and Discovery Sport MHEV vehicles.
Country of origin: United Kingdom
Alert submitted by: United Kingdom
Products were found and measures were taken also in: Slovenia"

Ford and BMW have also had to carry out a recall on all PHEV’s manufactured around the same time due to fires caused by contaminated cells in the battery packs made by Samsung. Wasn’t it Samsung who had a similar problem with their mobile phone batteries recently? I appreciate that PHEV’s and MHEV’s are completely different systems but the batteries are all from the same maker. Pangea Green D250 90 HSE with Air Suspension, Off-road Pack, Towing Pack, Black Contrast roof , rear recovery eyes, Front bash plate, Classic flaps all round, extended wheel arch kit and a few bits from PowerfulUK Expel Clear Gloss PPF to come

I thought the Ford/BMW issue was down to a physical fault with the welding on the battery packs - but JLR's recall, as detailed in the US, is for a software fix. If so then the issues must be completely different.

JLR have detailed previously that the BMS software was all in-house.

This is the Kuga recall notice:

"A12/01607/20
Product: Passenger car
Name: Ford Kuga PHEV
Company recall code: 20S61
Production dates: 13/01/2020 to 24/09/2020
Type of alert: Serious
Category: Motor vehicles
Brand: Ford
Type / number of model: e13*2007/46*2188*02
Counterfeit: NO
Risk type: Fire

Internal or charging fault could cause the High Voltage (HV) battery pack to vent hot gas. As such gases have not been routed away from other components, they will cause them to exceed their designed working temperatures. Overheating of components such as the fuel tank and fuel lines will increase the risk of the vehicle catching fire. / /

Measures taken by economic operators: Recall of the product from end users (By: Manufacturer)

Description: Kuga Plug-In Hybrid Electric Vehicle (PHEV), fitted with a Hight Voltage (HV) battery pack. Produced from 13/01/2020 to 24/09/2020.
Country of origin: Spain
Alert submitted by: United Kingdom
Products were found and measures were taken also in: Germany"
