“My exact vehicle Ram Promaster i4 3l turbo diesel with factory air is on a safety recall for bad coolant fan, but chrysler is saying that my VIN does not qualify. The chrysler dealer tells me I need to replace my cooling fan because it is shorting and blowing the fuse and possibly affecting the relay also. This fan code is also putting the van in limp mode and not allowing the diesel particulate filter to be regenerated. …”

“Bcm is bad dealer says not an item covered under warranty. Vehicle has 23000 miles on it and is only 2 years old. Dealership is not be honest with repairs and held vehicle hostage in order to get vehicle back from them we had to pay a service invoice for them looking at the vehicle $355.75. Again vehicle is not even 2 years old and only has 23000 miles on it, I just bought it last month.”

“The car was stopped in the light, the radiator fan came on, it made a sound and then there was a burning smell. The car overheated and I stopped it to cool down. The radiator fan stopped and the car overheated. I took it to the dealership for review and was told to change the fan and fuses. Checking the recalls I found the NHTSA 19v-818, which matches the specifications of my car and the problem with the engine cooling fan. I await your prompt response to be able to solve my problem with the car.”

“My TPMS system has never worked reliably since new. It is on now and has been on intermittently for 40,000 miles. Typically it comes on and stays on for a week to a month and checking or adjusting tire pressure seems to have no effect on whether it is on or suddenly off for a month or two. I am concerned I might really have a failing tire or low pressure and because the light is on I cannot know. I understand the NHTSA requires this system. Is it safe to be so unreliable? It is on now on since oct 14th but the tires are properly inflated as has been true in the past.”

NHTSA complaint #11040999, filed 2017-10, 41,000 miles

“Vehicle was delivered with speedometer / instrument cluster that provides erratic information. Display gives incorrect warnings. Different functions cannot be set. Awaiting new speedometer cluster with current mileage programed on the odometer for 82 days. Vehicle must remain at dealer as new cluster is programmed with the mileage prior to shipping to dealership for installation.”
