The 2023MERCEDES-BENZE 450 carries 22 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2023 E 450 is engine with 5 filings, followed by power train (4) and tires (4). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 3 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 15 investigation files overlapping the 2023 E 450. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

RE: Continental Pro Contact GX SSR MOE 245/40 R19 98 H M+S Original factory installed Mercedes E450 tires. I had 3 blowouts from hitting small potholes on 3 different tires in 1.5 years. These are complete immediate blowout going completely flat on impact. It could have very dangerous if I were driving a little faster and fortunately there was no other damage to the car or other persons. In each case, I hit a small pothole, and the tire blew out, flat to the ground. Because these are run flat tires, on the first 2 incidents I was able to drive home and to the dealer for tire repair/replacement. The third one was so bad that I could not drive all the way home and had to get towed. But all 3 incidents were scary and dangerous because of the sudden blowouts. The tires were not repairable and had to be replaced. I believe that the Mercedes Tire inflation instructions is unsafe and they should put more air in the tires to protect from the rim cutting into the tire when hitti

I am submitting this complaint regarding serious and repeated electronic failures in my 2023 Mercedes-Benz E 450 that pose a significant safety risk to myself and other drivers on the road. The vehicle has experienced complete dashboard failures on multiple occasions, including the loss of speedometer, fuel gauge, and gear shift indicators. Most critically, the vehicle recently shut down while in motion, displaying a âmalfunctionâ warning and disabling the electronic steering system. I was unable to maneuver the vehicle off the road, creating an extremely dangerous situation. This vehicle has been brought to the dealership three or more times for the same issue, with no permanent resolution. I believe this constitutes a serious safety defect. I respectfully request that the NHTSA investigate this matter as a potential recall issue.
My vehicle is equipped with a camera system which, when in reverse gear, displays objects/people behind the vehicle and, when going forward to park, displays objects/vehicles ahead. For the first 11 months of ownership, the system has worked properly. For the last 6 months the system has worked intermittently. The vehicle, purchased new, is under warranty and has been returned to the dealership 4 times for software updates and and part replacements. Two weeks after the last visit, the camera system was inoperative again. Shortly after I returned home and went out again the camera system worked properly. Several years ago, Mercedes recalled 347,000 vehicles for a similar problem. My vehicle was purchased after the recall and did not fall into the category of vehicles that were recalled but it seems that, with the Mercedes brand, the problem still persists. To the extent the camera system will alert you to the presence of a person when backing up, this is a safety issue which ne
While driving, malfunction warning flashed on dash, followed by 48v malfunction warning, then engine coolant overheat warning. The car then went into limp mode and finally stopped completely. Luckily this occurred on a residential street and not on a high speed freeway - the car gave very little warning before drastically reduced speed and shutting down systems. A 48 volt battery problem should have a redundant system to prevent the engine from overheating and not shutting down the vehicle at speed. Very dangerous!

The fuel pump on my vehicle failed multiple times, including coming off start / stop at traffic lights, as well as when being started. When at a stop light turning from red to green, my car did not respond, putting me in danger of being hit from behind. The vehicle is being repaired under warranty at a manufacturer dealership. It appears this is a known issue under NHTSA recall 23V445000, although my vehicle is not currently included in the recall after a VIN search of the NHTSA check for recalls page. My vehicle exhibited the same signs as others affected by this recall, including flashing "malfunction" when it occurred.
This has happened once before and I reported it then. This time I was stopped at a stop light and when I pressed the accelerator to go when the light turned green, the engine was off and would not go. The screen only said "malfunction" and no error codes (as before). I pressed the start button to turn the car off and then restarted it. It was fine after that. I have left a message with my service agent at my Mercedes dealership. I had previously told them that this had happened before. I am concerned about the safety of a car the stalls like this. Please investigate. I see other reports about this from E class car owners on line in various forums.
I purchased an E450 Mercedes before reaching my first service appointment while driving my two daughters home from school the car began to shake uncontrollably, lost power, and then the engine light and oil lights came on. The car was towed to the manufacturer dealership for repair. It was determined that the piston number four was broken and the engine needed to be completely replaced. Less than two months after having the entire engine replaced the car broke down again with a similar shaking. This time one of my children and their friend were in the vehicle with me. The car was towed back to the dealership where they said the fuel pump went out and needed to be replaced. When I arrived to pick up the car, the technician pulling the car around noticed the shaking and the engine light on again. I did not leave in the car. The dealer kept the car to further investigate why the engine light was on again. Two days later they called to say theyâd been driving the car around to âair it

My 2023 Mercedes 450E car was purchased on June 11, 2023 and has 1,750 miles. On 2 to 3 different occasions, I was stopped at a light waiting to make a left turn, fortunately my light was red and not a green permitting turning, which would have meant I would have pulled up and into the cross section to prepare to turn; I pushed the gas in the drive position and large red malfunction letters displayed across the dashboard and the car just revved. I put it in park and then drive postion a few times and had the same result. Finally, I turned the car off and back on, put it in drive, pushed the gas and it went. I live in Miami, with the serious traffic congestion. The issues that my stalled car caused blocking other driversâ passage through a few lights, can only be imagined Fortunately, no accidents happened as other drivers attempted to get around my vehicle. The car was taken into service on October 9, 2023, many tests were performed, a diagnosis of the stalling problem was provided,

My first incident was on July 17, 2023, the transmission shifted from drive to neutral, with out me touching the gear shift lever in any way. My safety and any passengers I have in this car, could be at risk, at this point I was going about 40 MPH, going into a gradual curve, entering a Entrance to 95 north, I had slowed down to the entrance ramp speed, this is when the transmission went from Drive to Neutral, with out me touching the gear shift lever. I had a appointment at Quirk Auto Park, there service dept. in Bangor, Maine, no warning lamps came on the dashboard, they proceeded to put the diagnostic tool on the car, they came out maybe 15or20 minutes later, they didnât find anything. The first incident I also reported to the NHTSA. The second incident took place on 10/20/23, I was going under 25 MPH, I was into a left hand turn, the transmission came out of drive, and went into neutral, I did not touch the gear shift lever at all. There was no warning lamps that came on
