The federal safety agency campaign number: 07e033000 cummings engine serial number 46565687 on 6/02/2015 the wrist pin failed on this engine that fall in the serial number range 46543077 to 46603939. The wrist pin failed while driving on la 1 about to turn onto i49 causing catastrophic engine failure. The engine had to be replaced. Contacted tiffin about it and local cummins dealer at time of failure. Tiffin was unaware of recall and local cummins dealer would not work on the motor home. Had a local engine company do the replacement of engine and they were never made aware of the recall. Last night while researching the internet, I stumbled upon the federal safety agency campaign number. Called tiffin to confirm engine serial number was 46565687 and made them aware of the federal safety agency campaign number. Also confirmed with consolidated truck & service again to confirm they had not heard of the federal safety agency campaign which was "no". Then proceeded to call cummings 1‑800‑343‑7357 and was told to take it to the "local" dealer. Since that is where the motor home originally, they refused to work on it, work had been completed elsewhere then who inside cummings did I talk too? At that point he told me he couldn't help me and would not transfer me his boss. At this point I would like a contact at cummins who understands the problem and willing to work on covering the cost of replacing the engine that obviously failed due to a known problem.

- What is wrong
- Tiffin is recalling 3,507 my 2004-2007 allegro, allegro bay and allero bus, my 2004-2005 phaeton and my 2005-2007 zephyr motor homes equipped with a two-door refrigerator manufactured by the dometic corporation. The refrigerator may have a defect in the boiler tube. Pressurized coolant solution could be released into an area where an ignition source (gas flame) is present.
- Risk

Recall number 08V509000 · Recall details
Steering: gear box: shaft pitman
- What is wrong
- Certain motor homes built on freightliner chassis and equipped with zf model 8018 steering gears may have been assembled with the incorrect recirculating ball spacer. This could potentially allow the recirculating balls to escape from the recirculating ball circuit resulting in a loss of steering.
- Risk
- The operator may notice higher required steering wheel inputs, or the need for more steering wheel adjustments while driving in a straight line in combination with metallic cracking noises prior to a loss of steering. Loss of steering could result in a vehicle crash.
- Remedy
- Tiffin is working with freightliner to replace the steering gear free of charge (please see 07v343 and 07e049). Owners may contact freightliner at 1‑800‑547‑0712 or tiffin at 256‑356‑8661.
Recall number 08V027000 · Recall details
Electrical system
- What is wrong
- On certain motor homes containing a 50 amp transfer switch built by intellitec, the material used for the wire lugs was changed from nickel plated to copper lugs. The copper lugs are softer than the nickel plated and do not retain the torque of the screw that clamps the wire connector.
- Risk
- When the torque is relaxed, the lugs can become loose resulting in excessive heat within the connected wire that could result in a fire.
- Remedy
- Dealers will replace the changeover box. The recall began on july 21, 2005. Owners may contact tiffin at 1‑256‑356‑8661.
