“Recall Remedy Failure NHTSA Recall Numbers: 25V-720 (67C) & 25V-552 (59C) I am reporting a failure by FCA US LLC to provide a timely remedy for Recall 25V-720. As of Jan 2026, the remedy remains under development since Oct 2025. Specific Safety Concerns for RV Owners: My vehicle is a 2022 Thor Tellaro motorhome.

“There were two recalls for the Carefree Awning unexpectedly deploying on Winnebago Travato camper vans. I recently went in for the 2nd recall and after completing it, the awning failed when the shop was testing it after completing the recall. Recall letter arrived on April 8th and called my dealer (McLain’s in Denton) on April 9th, and they ordered parts. They texted on June 13th to say the parts had arrived. I called and scheduled the first slot. I arrived on Jun 24th at 9am. …”

“12/2020 First the TPS sensor failed at 1,000 miles and almost caused an accident. Would not go over 25mph, was shifting hard, and the service engine light was on. Verified and replaced at dealership. Second, the rear view camera stopped working while backing up and almost caused an accident - no back windows - major safety issue. Replaced by me as they have no replacement for it even though its under recall. No warnings. Third, the transmission was shifting hard and fell out while I was driving on the freeway at 55,000. Damaged transmission and crankshaft and joints. …”

“While driving on a straight highway, no wind, no weather, 65 mph, both hands on wheel, the van started revving and lost power. I pulled over with engine still running. There were no codes or warning light. I tried to drive again. It continued to rev and not get up to speed. I pulled over again and shut it down. I waited a few minutes and then started it. When pulling back on freeway it ran normal with no more issues for another 700 miles. I took it in to the Dodge dealer on 1-13-23 to have it checked. They couldn't find anything. …”
