2021 MERCEDES-BENZ GLE 350 Engine Problems

While driving at night all error light showed up. I slowed down to the side of the road and while I was slowing down the engine died. I tried to start the car which worked but when I pressed the gas the engine died again. Tried it two more times with the same results. Then turned the car and waited a bit with the engine running. slowly started driving and was able to get home driving 20 mph. The next day took it to a shop that said that the battery was weak and they replaced the battery. Drove out of the shop and started hearing nosies from the engine. Immediately came back and was advised to take it to the dealer. Towed it to the dealer that checked it and said that they found metal in the oil filter and that I need to install a new engine. I...

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...

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...

I am writing to document a recurring and serious issue with the Mercedes-Benz GLE equipped with the M264 engine, specifically relating to premature cylinder head failure. In my case, the vehicle began showing the following symptoms: Rough engine idle and noticeable vibration during startup Loss of power, especially when accelerating Check engine light with fault codes related to misfire or combustion issues Oil and/or coolant loss, with no external leaks Engine knocking or ticking noises near the top end of the engine After a professional inspection and diagnostic testing, I was informed that the issue is likely due to a defect or failure in the cylinder head, possibly involving warping, cracking, or failure of the valve seats or head gasket area. Upon further research, I discovered that this issue is not isolated. Multiple owners of vehicles with the M264 engine—including various GLE, C-Class, and E-Class models—have reported similar problems, often...

On May 26, 2025, around 3:00 PM, I was traveling with my family on a bright and sunny day, with no rain for several days leaving the roads dry. As we were on I-35, I took an exit, and just a few seconds later, my 2021 Mercedes-Benz GLE 350 unexpectedly shut off, all the lights on the the dashboard lit up, and the vehicle came to a sudden and complete stop. Thankfully, this incident occurred on the service road rather than the highway, and we were at low speed otherwise it could have posed a serious risk to my family and me. Once the car stalled, both the steering and tires locked up. However the vehicle had power but would not start or move. As the same situation could happen to someone else which could put them at serious risk it might be in the best interest of Mercedes-Benz to...

While driving at about 55mph on road with one lane going each way, the car engine shut off, all instrument displays went off. There was no check engine light, warning or noise. I was almost rear ended by a car behind me. The car behind me swerved barely missing me, but almost hit oncoming traffic. Once car was on side of road it would not start. I tried to jump car battery with NOCO jump starter and it did not work. Instrument display did not come on, car transmission stuck in Drive. After testing battery with digital voltmeter it showed 12.6V, but car would still not come on nor would instrument display. Car had to get towed to dealer where it's currently at being diagnosed. This was very dangerous and could have been fatal.

My Mercedes gle350 2021 is having a cylinder misfire. I had the repairs done last February. Carlton Mercedes acknowledged this is a known issue with this car. Did some googling and saw how big of an issue this is in this car. Repairs were made and now a year later cylinder misfire again! My neighbor has the same car but 2022 having the same issue currently. This needs to be recalled. Mercedes needs to be held accountable for this issue. It’s costing people anywhere from 7-15,000 dollars to repair and most of these cars only have around 50,000 miles on them! It’s insane!!

On August 6, 2024 my vehicle reported " The state of charge of the starter battery in the vehicle Mercedes-Benz GLE 350 SUV is very low". We took it to our local dealership to have the battery replaced but upon receiving the vehicle we started having issues. The vehicle would shake and loose power. Upon turning off and turning back on the vehicle would continue working properly. We proceeded to have a local shop diagnose it since our 2021 vehicle was about 10k over the covered warranty and our local MB dealership is not very efficient. They recommended remove and replace engine cylinder head assembly. The warning lamp was for the battery and what followed after the starter battery getting replaced was the engine light. The problem that was concerning was the loss of power driving on the expressway. The vehicle is available for inspection upon request. Vehicle diagnosis from...

Component: Faulty exhaust valves caused the vehicle engine to misfire while driving at high speed (80mph) and required cylinder head replacement. Available for inspection. I was driving through a heavy rainstorm at night on I [XXX] toward Roanoke on [XXX]. While I was driving at speeds between 80-84 mph during a work trip from Texas to Virginia, the vehicle suddenly started shaking vigorously and I was unable to accelerate over 50mph. No alerts came on my system dash nor the MercedesME app on my phone, however, I did notice the ‘check engine’ light suddenly came on. It was very shaky but I was able to continue driving at the slower speed and with the vehicle heavily shaking. The problem was inspected and repaired under warranty by Mercedes-Benz service in Alexandria, VA. Had the 2021 vehicle been out of warranty, the repair would have cost around $10,000 according to Mercedes-Benz service....
