Summary
Daimler Coaches North America (DCNA) is recalling certain 2018-2019 Setra S407 and 2019-2020 S417 passenger coaches. The engine compartment flap may not have sufficient welding seams on the hinges, allowing the hinge connection to fail and the engine compartment flap to detach from the coach.
Remedy
DCNA will notify owners, and dealers will inspect the engine compartment flap seam welds and, if necessary, re-weld or replace the engine compartment flap, free of charge. The recall began August 28, 2020. Owners may contact DCNA customer service at 1-905-403-7807. DCNA’s number for this recall is 75.00U20104A.
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.
COMPLAINT
The weld seams on the brackets of the engine compartment flap were not executed fully.
CAUSE
Error in the documentation.
REMEDY
Check the weld seams on the brackets of the engine compartment flap against the latest documentation and, if necessary, incorporate the missing weld seams.
If the weld seams cannot be incorporated, the engine compartment flap must be replaced with a new one.
MEASURE TYPE
The scope of the work is carried out as part of a safety recall (RC).
REPLACEMENT PARTS REQUIRED
| Quantity | Designation | Number | Comment |
| 1 | Engine compartment flap | A 629 750 40 33 | Only if required |
Procedure
Warning
Risk of injury. Danger due to the dropping of unwieldy or heavy components. The unforeseen dropping of components can result in serious injuries to the body and limbs.
Warning
Risk of accident. Danger when lifting and transporting heavy components. The use of defective or unsuitable lifting equipment and hoists for the lifting and transporting of heavy components could result in serious or fatal injuries to all persons involved if the component were to drop or slip.
Warning
Risk of entrapment and crushing. Danger to hands, arms and legs during all work on doors, flaps, covers and roof hatches.
Warning
Risk of injury. Danger from the spontaneous opening or dropping of flaps, doors, covers and panels. There is a risk of flaps, doors, covers or panels that have been closed or fitted incorrectly opening or coming loose spontaneously, especially while the vehicle is in motion, and thereby causing injury.
Warning
Risk of entrapment and crushing. Reaching in between mechanically operated parts may result in serious injuries due to the severing or crushing of body parts.
Warning
Risk of fatal injury. Risk of fatal injury due to high voltages present during electric arc welding. Risk of explosion when welding near highly flammable materials. Risk of injury from welding spatter and ultraviolet light during welding. Risk of poisoning from inhalation of welding fumes. Welding sparks and splashes of liquid weld matter could cause severe burns if they come into contact with unprotected parts of the body. The ultraviolet light emitted during electric arc welding may cause damage to the eyes and burn unprotected skin. If electric welding work is carried out in a damp environment or on a wet surface, there is a risk of fatal injury as the voltage may be discharged through the human body. This could cause severe burning, cardiac fibrillation or heart failure. Standard work clothes (made of cotton or synthetic fibres) may catch fire due to welding sparks and splashes of liquid weld metal, and inflict very severe burns as a result.
Caution
Irreparable damage due to overvoltage and risk of fire. Measures required for the prevention of damage to buses or components during electric welding work. In order to prevent damage, the following measures should be carried out before the commencement of welding work:
Warning
Risk of explosion and poisoning. Risk of explosion and of poisoning from solvent vapours and gases. There is a risk of injury to the eyes and skin when handling corrosion inhibitors. Do not spray corrosion inhibitor onto naked flames or red-hot materials. Keep corrosion inhibitor away from sources of ignition at all times. Carry out the work in well-ventilated rooms and wear respiratory protection.
Warning
Risk of accident. Danger from unauthorised starting of the engine or movement of the vehicle. Persons in areas of the bus that are hidden from view (underbody, rear, roof, etc.) are at risk of injury if the engine is started or the vehicle is moved by other or unauthorised persons.
Checking the weld seams
- Open the engine compartment flap.
- Check the weld seams on the brackets of the engine compartment flap against the latest documentation. Result 1 / 2
All weld seams present in accordance with the documentation.
▶ No further work necessary, close the engine compartment flap.
Result 2 / 2
Not all weld seams are present in accordance with the documentation.
▶ Remove the engine compartment flap and incorporate the missing weld seams in accordance with the documentation.
Completing the weld seams
- Abrade the weld area down to bright metal and clean.
| Required material |
| Pneumatic brush grinder
Model: MBX® Metal Blaster® |
- Cover or mask off adjacent areas extensively and provide protection against flying sparks.
- Incorporate the missing weld seams to a professional standard.
Note
To ensure that the optimum welder setting is used, it is advisable to perform a test weld on a scrap sheet beforehand.
- Remove burn-off deposits and clean the welding point.
| Required material |
| Pneumatic brush grinder
Model: MBX® Metal Blaster® |
- Apply primer and corrosion inhibitor.
Note
Observe the application information and drying times of the paint manufacturer.
Fitting and adjusting the engine compartment flap
Note
Whenever you are adjusting flap gap dimensions, always take into consideration (adapt to) the gap dimensions of adjacent components.
Note
The following priorities govern the adjustment of exterior flaps: Priority 1: leak-tightness of the flaps. Priority 2: gap dimensions, appearance of the gap line and evenness of the outside of the flap surface in closed condition. Priority 3: gap dimensions, position and evenness of the outside of the flap surface in open condition.

| Uniform gap line from (1.1) to (1.2), permissible deviation | 1.5 |
Note
Adjust all gaps around the engine compartment flap in such a way that their dimensions are as equal as possible. The maximum relative deviation is 1.5 mm.

SUBJECT: SAFETY RECALL OF 2018~2020 SETRA S407 & S417TC COACHES
Ref.: NHTSA recall reference # 20V-394
Setra Bulletin # TI 75.00U20104A
Dear Setra Owner,
This notice is sent to you in accordance with the requirements of the U.S. National Traffic and Motor Vehicle
Safety Act.
EvoBus GmbH (the manufacturer of Setra coaches) has decided that a defect (details below) which relates to
motor vehicle safety exists in certain 2018~2019 Setra S407 and certain 2019~2020 Setra S417 vehicles.
EvoBus therefore has initiated a recall of these vehicles. Our records indicate that your vehicle is included in
this group.
Due to an error in manufacturing, the welding on the hinge mounting of the engine compartment flap could be
incomplete. This could reduce the overall strength and stability of the hinge possibly resulting in the engine
compartment flap becoming detached. A detached engine compartment flap could increase the risk of injury or
a crash.
Setra will remedy this by inspecting the welding seams on the hinge mountings of the engine compartment flap
and, if necessary, re-weld or replace the engine compartment flap. This repair will be performed free of charge.
Details are outlined in the repair procedure number TI 75.00U20104A. Please allow for up to three (3) hours to
schedule and complete the repair.
Please contact DCNA Customer Service Line at 1-800-206-9728 if you need further information.
Setra strongly urges you to perform the recall inspection work on your vehicle(s) as soon as possible.
