August 16, 2019 NHTSA CAMPAIGN NUMBER: 19V605000
Coolant Pump Electrical Line May Chafe
A malfunctioning engine coolant pump can increase coolant temperatures, possibly leading to an engine stall. Deactivation of the 48V on-board electrical system can cause the vehicle to not restart after using the ECO start/stop function or “Glide” mode. Either of these scenarios can increase the risk of a crash.
NHTSA Campaign Number: 19V605
Manufacturer Mercedes-Benz USA, LLC.
Components ENGINE AND ENGINE COOLING, ELECTRICAL SYSTEM
Potential Number of Units Affected 3,257
Summary
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2019 CLS 450 Coupe and CLS 450 Coupe 4MATIC vehicles equipped with 6-cylinder gasoline engines. The electrical line that supplies power to the engine coolant pump may contact the engine fan and chafe, possibly causing a malfunction of the coolant pump or a deactivation of the 48V on-board electrical system.
Remedy
MBUSA will notify owners, and dealers will inspect the coolant pump electrical line for damage, repairing it and rerouting it as necessary, free of charge. The recall began November 1, 2019. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA’s number for this recall is 2019090019.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

| This is to notify you of a Recall Campaign Launch regarding the wiring harness for the electric coolant pump on 3,264 Model Year (“MY”) 2019 CLS-Class (257 platform) vehicles. The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs will be flagged in VMI as “OPEN” on October 18, 2019. | |||
| Background | |||
| Issue | Daimler AG (“DAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2019 CLSClass vehicles (257 platform) equipped with a 6-cylinder gasoline engine (M256), the electric power supply for the engine coolant pump might contact the engine fan and chafe. Chafing of the electric power supply for the engine coolant pump could lead to a malfunction of the engine coolant pump and/or a deactivation of the 48V on-board electrical system. If the engine coolant pump malfunctions, the engine coolant temperature might increase, potentially leading to an engine stall. If the 48V on-board electrical system becomes deactivated while the engine is running, the vehicle can continue to be driven. However, a restart of the engine would not be possible if the engine has been switched off by the ECO start/stop function or by the “Glide” mode functionality. In both cases, the vehicle propulsion would be lost, increasing the risk of a crash. | ||
| What We’re Doing | MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will check for damage on the electric power supply to the coolant pump and repair it, if necessary. Additionally, the routing of the electric line will be modified in order to prevent potential contact with the engine fan. | ||
| Parts | The remedy is available and can be performed. | ||

| Given this notice, it is a violation of Federal law for a dealer to sell or lease any new MY19 CLS-Class vehicles in dealer inventory covered by this notification until the vehicle has been repaired. Once the remedy is available, the vehicles will be flagged as “OPEN” and Work Instructions will be available in Star TekInfo. Once the repair is complete, the vehicle may be sold or leased.
Loaner and demonstrator vehicles may continue to be driven, but must not be retailed until repaired.

Chronology-Only section
Chronology of Defect/Noncompliance Determination
In the end of November 2018, DAG received a single field report describing an instance of a malfunctioning electric power supply to the engine coolant pump due to chafing on the engine fan. This report was considered to be an isolated event, however, DAG initiated an investigation to understand why the electric power supply had come into contact with the engine fan.
Although the investigation did not reveal broader concerns relating to the routing of the wiring harness, an additional fixation clip on the wiring harness was implemented in January 2019 as a measure of continuous improvement.
After a second field report was received from a vehicle produced before the introduction of the additional clip, further investigations were initiated in March 2019, as the report for this vehicle also indicated that the electric power supply to the engine coolant pump had made contact with the engine fan.
From April to May 2019, DAG considered the manner in which the wiring harness for the electric power supply was routed in the vehicles as well as the potential consequences if this wiring harness was not installed according to specification.
Based on findings from further field reports, from June 2019 onwards, possible consequences of damage to the wiring harness were analyzed.
The investigation concluded that due to tolerances in the length and routing of the wiring harness, under certain circumstances it could potentially come into contact with the engine fan.
The investigation also found that if the insulation of the wiring harness were damaged by the engine fan, the 48V on-board electrical system might be deactivated, subsequently leading to an engine stall in connection with the ECO start/stop and “Glide mode” functions, while a risk of fire due to short circuit could be ruled out.
Furthermore, it was determined that an interruption of the wiring harness would lead to a malfunction of the coolant pump, which could lead to engine overheating and a potential engine stall.
On August 9, 2019, DAG determined that a potential safety risk cannot be ruled out.After a second field report was received from a vehicle produced before the introduction of the additional clip, further investigations were initiated in March 2019, as the report for this vehicle also indicated that the electric power supply line to the engine coolant pump had made contact with the engine fan.
