High Pressure Fuel Pipe May Leak – 2023 McLaren Artura

SEOCONTENT-START

OMB Control No.: 2127-0004 Part 573 Safety Recall Report 22V-908 The information contained in this report was submitted pursuant to 49 CFR §573 Manufacturer Name : McLaren Automotive Incorporated Submission Date : DEC 08, 2022 NHTSA Recall No. : 22V-908 Manufacturer Recall No. : NR Manufacturer Information : Manufacturer Name : McLaren Automotive Incorporated Address : 1405 S. Beltline Road, Suite 100 Coppell TX 75019 Company phone : 646-429-8916 Population : Number of potentially involved : 164 Estimated percentage with defect : 100 % Vehicle Information : Vehicle 1 : 2023-2023 McLaren Artura Vehicle Type : LOW VOLUME VEHICLES Body Style : 2-DOOR Power Train : GAS Descriptive Information : The fuel pipes on the recalled vehicles were equipped with cold formed nuts, while the vehicles that were not included in the recall have fuel pipes thar were equipped with fully machined nuts. McLaren was able to identify the vehicles with cold formed nuts by reviewing its production records. Production Dates : OCT 08, 2021 – NOV 14, 2022 VIN Range 1 : Begin : SBM16AEA3PW000177 End : SBM16AEA1PW000372 ✔ Not sequential Description of Defect : Description of the Defect : The cold formed nuts of the high-pressure fuel pipes can potentially loosen from the male threaded outlet connection of the gasoline direct injection fuel pump when subjected to vehicle loads, in particular during dynamic driving manoeuvres commonly associated with track running. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : If the nut becomes loose, the seal between the end flare of the fuel pipe and the sealing cone of the pump outlet may be disrupted, leading to the release of fuel. The end flare of the fuel pipe is situated close to engine components which have a high operating temperature. If fuel is released in proximity to these components, it could result in thermal activity. Description of the Cause : McLaren has determined the cause to be the type of nut that was used to secure the fuel pipe to the gasoline direct injection fuel pump. The nut on the affected vehicles is a cold formed nut with rolled threads. McLaren has concluded that this nut may have a lower residual torque than is necessary to assure the Part 573 Safety Recall Report 22V-908 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 connection. McLaren considers this to be due to a low coefficient of friction as a result of the process used to manufacture a cold formed nut compared to the process used to manufacture a fully machined nut. Identification of Any Warning that can Occur : NR Involved Components : Component Name 1 : Left hand and right hand high-pressure fuel pipes Component Description : Fuel pipes equipped with15mm length, cold formed nuts with rolled threads) Component Part Number : 16FB270CP.05 (left hand) and 16FB626CP.03 (right hand) Supplier Identification : Component Manufacturer Name : NR Address : NR NR Country : NR Chronology : The specification for the fuel injection system on the vehicle originally called for a fully machined nut to be used. However, during March 2021, the nut supplier notified McLaren of an imminent stock shortage of fully machined nuts and proposed a switch to cold formed nuts, which were already used widely by their other customers. The cold formed nuts had been successfully validated by the nut supplier and in durability testing performed by McLaren. In June 2022, a vehicle with approximately 1000km of road use was driven on a race circuit, and a fuel leak occurred. Upon inspection, it was found that the cold formed nut of the left-hand high-pressure fuel pipe had loosened at the pump outlet connection. McLaren immediately commenced an investigation. This investigation concluded that the cold formed nut had been attached with insufficient torque. To address this issue, McLaren developed and validated a bespoke tightening procedure for the cold formed nuts. McLaren reworked all the vehicles which had cold formed nuts using the bespoke tightening procedure. Note, at this point, the vehicle was not yet been launched for sale to the general public so no vehicles produced with the original tightening procedure were ever released to the public. Part 573 Safety Recall Report 22V-908 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 In September 2022, McLaren began using fuel pipes with fully machined nuts on its production line. McLaren chose to take this action because the fully machined nuts were back in stock and did not require the bespoke tightening procedure that was required for the cold formed nuts. At the beginning of November 2022, a different vehicle with approximately 2800km of road use was driven on a race circuit by a McLaren professional driver, and a fuel leak occurred. Upon inspection, it was found that the cold formed nut of the left-hand high-pressure fuel pipe had loosened at the pump outlet connection. CHRONOLOGY IS CONTINUED IN THE “MANUFACTURER COMMENTS TO NHTSA STAFF” FIELD BELOW Description of Remedy : Description of Remedy Program : McLaren will replace the high-pressure fuel pipes, which are equipped with 15mm cold formed nuts with rolled threads, with new high-pressure fuel pipes equipped with 16.5mm fully machined nuts with cut threads. This remedy will be carried out at no charge to the customer. Since all of the covered vehicles are covered by warranty, there is no need for a reimbursement program. How Remedy Component Differs from Recalled Component : The fully machined nuts with cut threads have a higher coefficient of friction than the cold formed nuts with rolled threads. Identify How/When Recall Condition was Corrected in Production : On 17 September 2022, McLaren began using fuel pipes equipped with fully machined nuts.

Immediate Action Required Beginning on Tuesday 20 December 2022, Retailers must contact customers and make service appointments as soon as reasonably practical. Repairs are to be performed by any McLaren Authorised Retailer regardless of where the vehicle was purchased. Retailers must not refuse to repair a vehicle because it was not purchased from their location. 3. Overview McLaren have launched a voluntary safety recall on the affected vehicles listed in section 7 of this bulletin. The covered vehicles may have been fitted with an incorrect high pressure fuel pipe which could cause a fuel leak and as a result an increased risk of thermal activity. Customers may continue to use their vehicle until it is brought in to have the procedure completed. Based on all of the information available to us, covered vehicles can continue to be driven under standard road conditions. However, we would recommend the repairs are carried out as soon as possible. McLaren are only aware of this issue occurring under heavy vehicle load such as track driving, which we would recommend is avoided until the remedial action is carried out. If a customer reports a strong abnormal fuel smell or identifies a fuel leak, the Retailer shall: 1. Advise the customer to immediately cease using the vehicle. 2. Immediately inform your Regional Aftersales Manager and provide all such information as they may request. 3. Make arrangements for the vehicle to be transported to the Retailer and, if required provide a loan vehicle to the customer. If a loan vehicle is not available within the Retailer, contact the Client Services team for further support. 4. Procedure To complete the required work by this Recall Campaign please carry out the following steps: a. Inspect the engine serial number.
