What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2020 Entegra Qwest, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
I am reporting a severe, repeating, and life-threatening safety defect involving the Mercedes-Benz Sprinter chassis on my 2020 Entegra Qwest motorhome. The vehicle intermittently and without warning drops into "limp mode" while traveling at highway speeds. When this occurs, the vehicle suffers a sudden, drastic loss of propulsion, forcing the motorhome down to dangerously low speeds on active, high-speed roadways. This defect has created imminent near-crash conditions on multiple occasions, exposing my family and surrounding drivers to extreme danger. The vehicle has been taken to an authorized repair facility five separate times for this exact issue. The mechanics have been completely unable to diagnose or permanently repair the root cause of this failure, and the vehicle remains inherently dangerous to operate. We’ve asked Mercedes to buy it back or pay it off and they tell us too bad so sad can’t help you but they also said on the last invoice that they can’t fix it. I’m not sure what date to put below here on the additional details because it happened five times so I’ll show the last incident.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
