What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2021 Thor Motor Coach Omni, 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
The front cap above the drivers and passenger compartment come loose from the body. Mine has been to a few dealers and back to Thor's plant. They supposedly fixed it at Thor. But it is coming apart again. After Thor's head management came out and looked at it this last time they told me their is no internal support for the hole front cap. It's held on by self tapping screws where it meets the body of the camper and a few where it meets the truck cap. It is a fiber glass shell that flexes up and down while going down the road. The rear cap is the same way the screws that mount it to the camper are over tightened and fractures the screw heads. Both of these issues are very common on the Omni and Magnitude. The other issue is the suspension the chassis they put it on is to light for some models. Mine being one of the models the bh35. If a 18 wheeler passes you it will almost throw you off the road. Even if the rv is empty. Everyone with one of these. Has to put spring helpers on it to make it not such a handful. The tow hitch on them Is rated at 10,000 lbs and 1,000 lbs of tongue weight. However the ccc of the rv is only 1402lbs meaning if you put a 1,000 lbs tongue weight trailer on it. That only leaves 402 lbs of weight for inside. If you have a driver and passenger in it weighing 200 lbs a piece that leaves 2lbs for your clothes, food, water, bedding ,or anybody you might want to bring with you. The numbers here don't add up to me. And I believe this is a safety problem. Then the electric transfer switch. they put the fresh water tank in the same spot as all the electrical. Including the fuse panel, breaker box for 12v and 220ac power. They have left many wires loose on the transfer switch causing a buzzing noise. This has happened on many rigs. And the water tank leaks on many as well including mine it will flood the floor. Thor supposedly fixed this as well. Mine is still leaking. To me all these issues makes Mine unsafe to use.
We read on the Thor motor coach forum that there is an open recall on Omnis and Magnitudes built after 9/1/2020 for damage to LP gas line caused by the way it was routed near the springs. Our manufacture date is prior to this date, but my husband crawled under our unit just to have a look. Fortunately he did because we have a pretty severely damaged line! Thor has agreed to fix it, but has not altered their recall notice. Based on other chatter on this same forum, one owner discovered his LP line actually has a screw that protruded into his line through the floor decking. These units are ticking time bombs! Additionally, we believe our coach is beginning to show symptoms of 'cap separation' - ie the bunk over the cab of the F550 chasis is separating from the rest of the RV 'box'. Again, the forum has numerous cases where owners have thried to get Thor to address this issue, but seems to fall on deaf ears. These caps are at risk of faling off the unit while travelling at highway speeds which can create catastopic accidents. The separation is occuring because of poor workmanship and use of screws that are not substantial enough to hold and/or too few of them. First symptom is the popping of trim pieces due to broken screws. Our local dealer replaced the broken screws causing the popping but won't look any further as Thor is not willing to compensate them.
