What happened when owners saw P1720?

…A subsequent authorized Jeep representative stated XJ1 would not apply without fault code P1720-00 or P215C-00 even if metal were present in the PTU, while acknowledging that the metal condition presented a safety concern. Despite documented PTU failure and metal contamination, it remains unrepaired because Jeep has conditioned XJ1 replacement on specified fault codes rather than physical findings. This follows the 2023 PTU-related recall visit, a later authorized dealer reporting no applicable codes and stating the PTU tested normally, and AutoNation requiring me to authorize a $295 diagnostic fee for yet another evaluation. Stellantis continues to require additional dealer evaluation…

…The codes that are under this warranty are P1720-00 and P215C-00. Chrysler is aware that this part is faulty and should be held responsible for fixing this as it could be deadly. Schenice, at Chrysler Jeep informed today there was a "warranty" for this specific code but that it expired on January 22nd 2023, we were never made aware of this or it would have been fixed as I have children I drive around with. Something that could be deadly should never have an expiration date on the warranty. We take our vehicle to Kaiser Bros. for all repairs and maintenance and this was never once brought to our attention.
