Everything below is an owner-reported complaint submitted to NHTSA about the 2023 Heartland Big Horn, 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.

From owner reports, verbatim
Range is installed in our Heartland RV. Suburban put out a TSB to have silicone placed at wiring connections on stove knobs under stove top. Then they put out a recall to disconnected and cap the wiring for the illumination of the stove knobs and the oven lighting. The range has an issue with the temperature control that it doesn’t reach indicated temperature. The main issue is that when the pilot is lit and you set it to a temperature like 300 degrees it lights okay. But, after a few minutes the burner goes out and so does the pilot. You have to continually relate the pilot and each time turn the range to a higher temperature to keep the burner in the oven on to cook anything. Suburban has indicated that it is a manifold issue on the top of the stove but has not provided any corrective action or recall on any of this. The Range should be recalled and replaced.

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.
