2020030016These are vehicle campaigns — the ones the automaker filed against this model. NHTSA also records equipment recalls, filed by a parts maker against a component (a tyre, a child seat, an aftermarket part), and those are not listed here or counted above. nhtsa.gov/recalls shows both for a VIN.
Whether any of this applies to one specific E-Class
A campaign covers a build range, not a model year, so two identical-looking cars from 2020 can differ. Both of these check a VIN against the manufacturer’s own list, free, in about ten seconds. Mercedes-Benz publishes its own lookup because federal rule 49 CFR 573.15 requires it to, and to keep it current to within seven days.
Hear about a recall before the letter does
The manufacturer’s letter is the last step of a recall: it has up to 60 days after filing to mail owners, at the address on the registration. We email you the day NHTSA posts a recall on the 2020 Mercedes-Benz E-Class, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

Most-cited components
In owners' own words
Filed with NHTSA by the people who own these cars, one per problem area. Quoted as written, with anything identifying removed.
My 2020 E450 has not been serviced on schedule due to Mercedes-Benz of Indianapolis and its service manger banning and blacklisting me for months. This service department would not allow my vehicle to be serviced under a prepaid maintenance and wheel and tire plan, and most importantly my vehicle's warranty.
The contact owns a 2020 Mercedes-Benz E-450. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed and there was an abnormal sound coming from the vehicle. The dealer was contacted by phone and made aware of the failure.
Back up camera not functioning. Emblem cover will not retract. Must use key fob or electronic controls to open the trunk
Rear glass window on convertible soft top is prematurely separating/delaminating from top assembly on 2020 Mercedes-Benz E350 convertible with under 8,000 miles. Glass is integrated into the convertible top and failure may lead to reduced rear visibility, possible glass detachment, water intrusion, and safety hazard while driving.
The Engine Electrical harness is completely corroded after only 50,000 miles requiring a 4k+ repair. Oil leaking from the camshaft sensor pushed it way all throughout harness. There are no warnings as it will only be noticeable after doing routine maintenance OUTSIDE of the manufactures warranty.
Over the last couple of days, my car has displayed the "Engine Warning" message intermittently. I took this to the dealership for inspection and received the following fault code: P06DA00 - Inoperative Oil Pump Valve. For a car with low mileage, this could potentially be a car issue.
Complaint counts are raw owner reports to NHTSA, not verified defects, and scale with how many were sold. Use them to spot patterns, not to rank.
Reported by Mercedes-Benz itself: 9 death-or-injury claims on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 1 killed, 9 injured, as claimed, not verified — about 35 per 100,000 built. Every E-Class model year, by year and system → Dated and by system, they are exhibit F of the defect dossier.

A service bulletin is the manufacturer telling its dealers how to diagnose or repair a known condition. It is not a recall, not a finding that the vehicle is defective, and the work is not automatically free — though a bulletin is often what a dealer works from when you describe a symptom, so quoting the document number can save a diagnosis. The count is every communication filed; the list shows the most recent, one entry per campaign, because a single campaign is usually filed as several documents on the same day. The summaries are NHTSA's; the full documents come from the manufacturer.
Diagnostic trouble codes on file
Source: NHTSA manufacturer communications and complaintsCodes documented against this model year in the federal record. A code appearing here does not mean this vehicle will set it — it means the code is part of this nameplate-year's documented history.

Generic codes (the second character is 0 or 2) mean the same thing on every vehicle sold in the United States. Manufacturer-specific codes (1 or 3) mean whatever the automaker assigned, and no honest source can define them for you — which is why the ones here carry the evidence instead of a definition. A code is a link when enough separate federal documents name it across the catalogue to be worth a page of its own; the rest are listed here, where the vehicle is the context that makes them mean something.

At the New York inspection station
Source: New York State DMVIn New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2020 Mercedes-Benz E-Class failed the emissions check on 1.1% of first inspections — lower than the 2.2% for every 2020 model-year vehicle inspected; and the safety inspection on 1.0% (every 2020 vehicle: 1.6%).

New York’s emissions test on these model years is an on-board diagnostics check: it fails a car whose check-engine light is on or whose self-tests have not finished. First inspections only, so a car that failed and came back is counted once; private and special plates, not taxis, livery or commercial plates. A rate appears only where at least 200 inspections stand behind it. “Every 2020 vehicle” is every 2020 model-year car, SUV and pickup inspected in the same window, all makes.

E-Class by model year
all years, side by side →Common questions about the 2020 E-Class
Source: EPA, NHTSA and manufacturer press kitsDoes the 2020 Mercedes-Benz E-Class have any recalls?
NHTSA has posted 16 recall campaigns for the 2020 Mercedes-Benz E-Class, 1 of them rated critical. The most serious on file is 24V445000, covering Electrical System. 2 of them were filed with no repair available at the time — NHTSA's file records what the manufacturer had in hand on the filing date, not what exists today. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2020 Mercedes-Benz E-Class?
NHTSA gave the 2020 Mercedes-Benz E-Class 5 stars overall in its New Car Assessment Program tests — 5-star frontal crash, 5-star side crash, 5-star rollover. WhichTrim also grades it F (45/100) on its recall record, which is a different question from crash protection.
What is the fuel economy of the 2020 Mercedes-Benz E-Class?
Across the 13 EPA-rated configurations of the 2020 Mercedes-Benz E-Class, the best EPA combined figure is 26 mpg. Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2020 Mercedes-Benz E-Class?
Transport Canada measured it at 190.2–196.9 in long, 72.8–73.2 in wide (body, without mirrors), 56.3–58.3 in tall, on a 113.0–115.7 in wheelbase. Curb weight: 3,957–4,566 lb depending on configuration. Those are its measurements of the North American versions; every figure is in the table above.
What do owners complain about on the 2020 Mercedes-Benz E-Class?
Owners have filed 24 complaints with NHTSA about the 2020 Mercedes-Benz E-Class, most often about engine, unspecified, back over prevention. Of those, 2 a fire, 4 reported injuries. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.
How clean is the 2020 Mercedes-Benz E-Class?
The EPA smog rating for the 2020 Mercedes-Benz E-Class runs 3 to 6 out of 10 across its configurations. That score covers tailpipe pollutants other than greenhouse gases, and it only compares vehicles within the same model year. It is certified for all fifty states, so it can be registered new anywhere in the U.S. Its configurations were certified to different standards — California LEV-III ULEV125, California LEV-III ULEV50, California LEV-III ULEV70, Federal Tier 3 Bin 125, Federal Tier 3 Bin 50, Federal Tier 3 Bin 70 — which the table above lists per configuration.
Are there service bulletins for the 2020 Mercedes-Benz E-Class?
The manufacturer has filed 1124 service bulletins and related communications with NHTSA for the 2020 Mercedes-Benz E-Class, most often covering electrical system, equipment, power train. The most recent is dated 2026-09-26. A bulletin is not a recall: it is the repair procedure a manufacturer sends its dealers for a condition it knows about, and the work is not automatically paid for. It is still worth knowing — if the symptom matches, quoting the bulletin number at the service desk can save a diagnosis. The document numbers and summaries are listed above.
How does the 2020 Mercedes-Benz E-Class do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2020 Mercedes-Benz E-Class failed the emissions check on 1.1% of first inspections — lower than the 2.2% for every 2020 model-year vehicle inspected; and the safety inspection on 1.0% (every 2020 vehicle: 1.6%). The figures are New York State DMV’s own inspection records, first inspections only, and the table above sets each one against every vehicle of the same model year.

Sources & method
Safety Signal starts every model-year at 100 and subtracts points per open NHTSA recall campaign by severity: critical 15 (fire risk, park-outside or do-not-drive advisories), high 8 (brakes, steering, airbags, loss of drive power, structure, battery), moderate 6, minor 3 (software, labels, lighting fixed by an update). The most serious recall counts in full and each further one counts 85% of the one before, because a vehicle sold in millions is recalled more often than a rare one without being more dangerous — and because a flat subtraction bottomed the scale out, scoring a vehicle with 22 recalls within a point of one with six. A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, otherwise F. Read it as what it counts: recall campaigns on the federal record, weighted by severity. The damping reduces the sales bias by roughly 40% but does not remove it: like our complaint counts, this is not normalized by how many were sold, so a best-seller still scores somewhat worse than an obscure model with the same real risk. NHTSA crash ratings, do-not-drive and park-outside advisories, and the crash, fire, injury and death counts in owner complaints are reported separately on every page and never blended into the letter — a vehicle can hold five stars and a poor letter at once, and where that happens we say so rather than leave you to notice. Because the scale subtracts from a clean sheet, a model year too new to have been recalled, complained about or bulletined scores full marks on an empty record; we label those grades provisional rather than present them as earned.
EPA figures come from fueleconomy.gov vehicle records. Recalls, complaints, investigations and crash ratings come from NHTSA's public flat files, refreshed nightly.
