I own a 2016 Jeep Cherokee Limited 4×4. The SERVICE 4WD light came on a few weeks ago. After research and several mechanic’s input, I was told the problem was the PTU, and, since Jeep no longer makes the part, I was given the quote of $2700-$3200 to replace the PTU with a remanufactured part with only a one year warranty. According to the mechanics, when driving with a broken PTU it may cause damage to the drive shafts. transmission and axles, which, in turn can break while in use, leading to a very dangerous situation. I was told that I should put the Jeep in two wheel drive manually and drive it like that, but my shifter dsn’t have that option. It shifts automatically. So, I have a bad PTU, but my VIN dsn’t have a recall, and there are several people with the same problem, according to the NHTSA site. I am filing this complaint so the NHTSA will step in and require the manufacturer to further the recall to include ALL of the VINs with defective PTUs and make them safer to drive. Yes, the vehicle is available to inspect at your convenience.
