2021 MERCEDES-BENZ GLE 350 Complaints

This is regarding a 2021 gle 350. The car was parked overnight and in the morning was unable to start or crank . I had to tow the vehicle to the service center that has maintained the car since purchased date and they told Me there’s a problem with the engine and I will need a new engine costing $28,000 dollars., the car has 42,000 miles and has an impeccable service history with Mercedes Benz. They did not tell me any specific engine part that’s faulty. There was no warning lights, check engine lights. Had I been driving this car and it happened it could have been catastrophic.

There is a known issue with the Cylinder Heads on specific models of Mercedes vehicles. Symptoms of M264 Cylinder Head Failure If your GLE 350 is experiencing these symptoms, it may be covered under the extension: Check Engine Light (MIL): Often triggered by misfire codes. Rough Idle: Noticeable shaking or uneven idling when stopped. Loss of Power: Potential stalling or significant power reduction during acceleration. Low Compression: Diagnostic tests often reveal low pressure in one or more cylinders. This is not being addressed my Mercedes USA where Mercedes Canada has offered an extended warranty. Using social media I have comprised a list of over a hundred impacted owners. Many more exist. What this does is cost catastrophic failure of the engine leaving the driver stranded in whatever lanes they were traveling in. I am disabled and for me this created a life threatening situation. When reaching out to MBUSA the answer is simply "not warranty exists" where MB Canada has extended the warranty to an additional 15k miles from notice. My engine blew. The replacement cost is near $20,000 dollars. The mileage on my engine was 65k. Many others are impacted and a class action lawsuit is the only other course of action it seems.

Sunroof makes loud, high pitched noise when it’s windy or driving high speeds. Sunroof complaints found online for bad seals or components of sunroof being bad or unaligned. Sounds could cause driver not to hear other safety issues with vehicle as well as leaking if water.

My vehicle suddenly started shaking and losing power, the check engine light came on and the problem continues to vibrate when idling, it will not shift into gear to go. Very unnerving and unsafe as it happened in a intersection. Sometimes it drives fine and then vibrates and goes into low gear and loses power. I took to a certified Mercedes dealer and they changed the spark plugs and 4 coils as well - After 4 weeks, I am told the CYLINDER HEAD needs to be replaced. It has 68k miles. The mechanic has already had 2 other 2021 GLE 350 with exactly the same issue. There are several similar cases discussed online as well.

Original owner of a 2021 GLE, purchased on April 21, 2021. The vehicle is currently 4 years and 6 months and 22 days old with approximately 49,000 miles. Despite meticulous adherence to all scheduled maintenance performed and no warning lights activated the vehicle suddenly shutdown and would not restart. According to MB maintenance department it suffered a catastrophic and complete engine failure. This type of premature and total engine failure in a properly maintained, low-mileage vehicle is clearly a defect in material or workmanship. This is a serious safety defect that rendered the vehicle completely inoperable with no warning. Issues are resulting from valve guide wear issues, camshaft codes, valve openness, and no-compression symptoms, camshaft, timing chain, etc.

we own a Mercedes-Benz GLE 350 model 2021. Our vehicles engine has stopped running on two different occasions, resulting in a very scary near miss accident situation. The first time this happened was it 22,000 miles, the engine shut off as a result of a failure in the engine cylinder head valve that burned up, causing the car to shut off in the middle of an intersection. The second incident happened at 56,000 miles where the vehicles engine shut off. This was also in the middle of an intersection, this time turning left in front of traffic. The reason why the engine turned off was because the lower part of the engine lost a rod bearing.this is what the dealership told us which cause the engine to have low compression and turn off. In both incidences, the check engine light did not come on. There was no warning. There are several people that have exactly the same problem with their vehicle and have also had the same two situations with two separate repairs made to their cars. People online are calling these Covid engines because the materials that were used to build the engines were made during Covid and they have defects. The GLA 350 model year 2021 appears to be the only year the GLE 350’s are having these issues. Mercedes-Benz refuses to acknowledge any of these issues and is not willing to help properly fix the engines. The only way to properly fix the engine is to completely replace it because it is full of defective parts and after the engine has failed the engines cannot be repaired.. This leaves us with no alternative to try and repair the vehicle ourselves so we are 100% relying on Mercedes to do the right thing and fix the problems that they caused to this 2021 model year GLE 350.
