Incident

Jul 1, 2026

The contact owns a 2016 Mercedes-Benz GLE350. The contact stated that while opening the door, a cracked fuel injector was spraying gasoline. When the door handle was pulled, an aftermarket module ignited the fuel, causing an explosion and heavy smoke from the engine compartment. The contact stated that the vehicle had been taken to the dealer previously for the same issue, but the dealer dismissed the information and returned the vehicle. Shortly afterwards, the failure reoccurred and was recorded. The vehicle had been at the dealer for two months, and the dealer blamed the failure on an aftermarket part, even though the dealer had installed the parts. The vehicle was driven to the dealer, where it was diagnosed with fuel injector failure and was associated with the aftermarket parts that were installed by the dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 133,000.

While waiting for traffic signal to change with foot on break pedal, the suv accelerated suddenly and lurched forward and rear ended the car ahead of me! Luckily, it was a Hummer with a tire mounted on the rear door and damage occurred only to my MB. Front end has severe damage, hood buckled and headlight broken! It was a spooky experience! 'chk breakpad wear' warning light has been coming on lately when starting and I was planning to get breaks chkd. But this was a frightening experience! Is there an issue with MB ECU like this? I'm in the process of filing insurance claim.

This has previously been reported, but NHTSA email indicated I needed to file formal complaint. Fuel injector(s) leaked while vehicle parked overnight in driveway. ECU detected fuel and subsequent ignition/spark caused "explosion' blowing out engine intake manifold (appx 50-75 pieces found). All 6 injectors and intake manifold required replacement. Mercedes Benz does have recall notification for failed/leaking fuel injectors, which includes both my model, and model year- but has claimed my VIN is not covered. MB recall campaign # 2022030003, dated 04/22/2022. I have retained engine intake manifold (main piece) for inspection. Fuel injectors were returned to MB. Safety risk is relatively obvious due to "explosion" and potential fire. Independent service agency (German Motors, Lakewood, CO- in business for over 25 years as MB only repair agency) diagnosed and performed repairs. Further, they informed me that in the investigation, they an other independent repair agencies/shops have in fact seen this before. No warnings, lights, or other symptoms were evident prior to injectors leaking.

Vehicle sitting in driveway. Fuel injector leakage and resultant engine control unit detecting fuel set off spark which resulted in explosion under hood. Completely destroyed engine intake manifold (over 100 pieces found), and requires all (6) new fuel injectors. Due to core return value, I will NOT be keeping injectors, but they have been inspected by certified mechanic where repairs are being done. Safety/risk is obvious- fire danger, explosion danger, etc. Vehicle was towed to German Motors, Lakewood CO. for repair. No warning indicators, no lights. Mechanics did inform me that this issue has been seen on other vehicles. Network of MB mechanics have been aware. MB USA is also aware of fuel injector leakage issues, and have issued a Safety & Emissions Recall Campaign (# 2022030003, dated 8/22/2022) for this model year and vehicle model type (GLE). MB USA however asserts that my specific VIN is not included in recall- but offers no reason. Currently, due to MB inability to provide replacement parts (engine intake manifold unavailable until Sept. 2025!), vehicle is still in repair facility. Invoices and write up will be available after repairs completed (using reclaimed intake manifold along with new injectors).

Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for "one hour" in removed condition 4. Reinstall side shafts Note: Before using the antifriction coating (Molykote), stir it or shake it thoroughly for (at least 1 minute).

Complaint Creaking noise, in irregular sequence when driving slowly in combination with slight steering movements and/or Creaking/crackling noises from the area of the wheel bearing on the front axle when cornering/ maneuvering.

Complaint Headlamp, front fog lamp leaky or fogged. Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps: 1. Drive vehicle into workshop (temperature higher than +18 °C/+64.4 °F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing of fogged/condensed LED headlamps and LED rear lamps on electric vehicles: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). 2. Connect battery backup via a charger. 3. Open the front-end flap and ensure sufficient ventilation. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in condensation, check the headlamp for malfunctions. (see Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Note: Only implement Remedy 1 for model series 463 (from model year 2018) and model series 465. Remedy 2 A defective headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness according to LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. Note: With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. • Open ventilation system LI82.10-P-078302 • Closed ventilation system LI82.10-P-078304
