We have a 2001 Rexhall Vision DP motorhome with a Cummins ISB engine that we bought used from an RV dealer in September, 2005 when it had 19K miles on it. We love the motorhome, but amongst the paperwork that came with it was what appeared to be a recall letter from Cummins dated October, 2001 addressing a problem with incorrect oil pressure sensor readings. It seems a limited number of new motorhomes built at that time had faulty oil pressure sensors that were sending false oil pressure signals to the ECM (Electronic Control Module) with Cummins ISB, ISC, and ISL engines. Apparently our motorhome was one of them.
I didn't think much about that recall letter until recently when I was reorganizing all the documents associated with the motorhome and decided to read it a little closer so I could decide how to file it. The letter went on to say that Cummins came up with a temporary fix to put a constant resistance into the oil pressure sensor circuit to make the ECM 'think' that the oil pressure was OK. So, in effect, the oil pressure guage reading was hard-wired to read 'good' for those motorhomes that had the temporary fix installed and wasn't displaying the actual oil pressure at all. Owners of these motorhomes were apparently directed to an authorized Cummins Distributor/Dealer to have the temporary fix installed.
The recall letter went on to state that Cummins would maintain the warranty responsibilities as stated in the motorhome's Owner's Manual. I assume the previous owner of our motorhome had the temporary fix installed and must have filled out the information card and sent it in so that he would be informed once a permanent solution was developed. I then searched through the rest of the paperwork we inherited for something to tell me that the permanent solution was eventually implemented. I found no such paperwork. Maybe he got the notice afer he sold the motorhome, I don't know.
Then I got to thinking, our motorhome's ISB engine has always shown excellent oil pressure, and in fact, I don't remember seeing the oil presssure drop appreciably when idling or increase when starting out from a stop. I have a considerable amount of diesel truck driving experience and am aware of how much and how often diesel oil pressure readings change. What if the previous owner received the notice for the permanent fix and did nothing about it? What if they never installed the permanent fix in our motorhome?
Now I was getting a little concerned, so I called the Cummins Customer Assistance Center and asked the guy there if he could answer my questions. I gave him our engine serial number and when he came back from his search, he informed me that our motorhome indeed had had the temporary fix installed but there was no record of the permanent fix ever being installed. He gave me the number of a local Coach Care center and said I should call them and make an appointment to have the permanent fix installed. So I called Coach Care immediately and after discussing it with several people there, they ended up telling me that I would have to pick up the cost for this fix because the two-year period that was set up for this particular recall had expired as of December 31, 2005. I called the guy at the Cummins Assistance Center back again and he said he would see if there is something else he can do to help me, but that was two weeks ago and nothing else has been done. I keep calling back to see if he's found out anything but all I've gotten is the run around. It looks like I'm stuck with the cost of this fix.
Incidentally, it looks like Cummins started installing the temporary fix for this problem as early as October, 2001. But it appears that a permanent solution wasn't implemented with a recall until January, 2004. So even though it took them more than two years to come up with a permanent solution, they setup the recall to expire in exactly two years. And they won't make an exception for those of us that got caught with the temporary fix installed but with no notification of the permanent fix recall. To me, it was their problem from the getgo, so why should I be charged to fix it?
