Six problems related to horn assembly have been reported for the 2009 Dodge Ram 1500. The most recently reported issues are listed below.
The total integrated power module failed and it's a common problem in all Chrysler and Dodge vehicles. That fails the engine runs rough, ac, brake light, turn signal, horn, wipers, stop working and transmission stays in 1st gear. The lights on the das stay brakes, abs, seatbelt, check engine light and air bag. . . This is an specially when the module fails while driving in the road. Dealers know it's a common problem but they rather have customer pay for a new tipm.
Windshield wipers on all the time, all trouble lights on dash are on, speedometer and tachometer are dead, front windows wont operate, back windows do operate. A/c will blow air but not cold air. Horn will beep intermittently when car not in use. No trouble codes when scanned. 2 dealers have identified it as the total integrated power module problem. Part is unavailable from oem as it is in "engineering review".
Our truck began stalling the engine at low speeds in Dec. 2015, I changed all 16 spark plugs thinking this would fix the issue, it didn't. About 2 weeks after this started, I was trying to unlock the truck with the key fob for a short trip into town. The headlights would flash, but the doors would neither lock or unlock with the fob. I opened the door with the key and started the engine. The idiot lights for the air bags and the traction control were both illuminated. We had never had any issues with any of this previously. Next, I tried to lock the doors for the trip, using the pdl switch and found it to be inoperable. Also not working were the pw, hvac system, horn, and windshield wiper system. This was so very strange that I googled these symptoms and discovered the tipm, totally integrated power module, for these vehicles are failing at an alarming rate. Thank god that my wife didn't stall this truck in a highway driving situation and become the victim of this known and documented safety flaw in these vehicles. Fiat/Chrysler needs to step up to the plate and repair these vehicles before lives are destroyed due to this defect.
Key fobs, remote door lock/unlock failing. Key fobs keep failing, buy new fobs and after about a year they fail. Owners resort to unhooking the horns as the horns sound when manually unlocking the doors with the key. This is a stationary failure of the fob. However if owners are disconnecting the horns, that would be a safety problem while driving when the need to alert other vehicles arises. Vehicle owners are not purchasing new fobs due to cost but rather disconnecting their horns so that the alarm does not sound when unlocking the drivers door to gain entry. Many owners are not reporting this defect due to the fact that they don't see it as a safety issue with the vehicle. A quick internet search reveals a vast # of complaints on website forums. Source-I am an ase master tech. I have an 09 1500 that this is happening to. I do not disconnect the horns but rather just don't lock the truck. (taking a chance against theft).
Our 2009 Dodge Ram 1500 is experiencing issues with the tipm (totally integrated power module). The vehicle starts intermittently and will/could stop running/shutdown at any time. We have had the truck serviced only to find that this particular part is about $650-800 to replace plus labor. The issue not only could be dangerous if the vehicle does not start but if it dies while operating. After extensive research it was discovered that this issue is not only a large issue in Dodge ram, but also in numerous other Chrysler vehicles. Some have experienced issues such as windshield wipers, the horn blowing, lights turning on and off randomly while driving. Even after removing the key and shutting down the engine, the issues would not shut off. The wipers can and have decided to not work, which could lead to a real hazard when driving in the rain. The check engine light comes on sporadically, as does the air bag light. Not knowing if the air bag will even function in an accident. There is an enormous backorder on the tipm due to the high volume of vehicles requiring replacement. I was told "unofficially" by a service rep that the reason for the backlog is also due to Chrysler changing the manufacturer and in turn, increasing the price of the part. This needs to be replaced at the cost of Chrysler, not the owner. This is a safety issue and needs to be recalled immediately! any help you can provide would be more than appreciated.
Truck purchased July 31st, 2009. Since then on four separate occasions with two different drivers, the horn has not worked when pushed. Truck was taken to the dealership twice since purchase. Dealership stated both times there was no found issue. Horn continues to intermittently not work, with two most recent occasions 2/ 16/10 and 4/13/2010. Speed varies from 30-70 mph when horn failure occurs.
