NHTSA Complaint #11444873 — 2018 RAM 1500

Cruise control on 65mph going down hill. Transmission dropped into a lower gear. Vehicle immediately slowed down immediately by probably 20-30 mph. Everything in vehicle was thrown forward. I struggled to keep control and thought I was going to roll and crash off of roadway, or hit another vehicle. This was not a problem for two years, until June of this year. Driven the same stretch of highway a dozen times without incident. 21,000 on vehicle now. I took the RAM tech for a ride to reproduce the incident. Did it on a small hill at 25-30mph and reproduced the problem several times at the same location of the hill. Transmission drops into lower gear, makes a kind of grinding or similar noise. Then it stays in this lower gear straining until the brake is pushed to turn cruise off. Told him of losing control on big hill and nearly crashing. No warning lights or warning of any kind. Their response that a slight speed change is BS. 65mph to 30 or what it was in a couple seconds is not slight. It also states temporary. Even with the tech seeing it, it is not temporary. You have to push the brake to get it back into the right gear. At 30mph on test runs. Losing control of vehicle and they come up with this. You can inspect my vehicle. No sales rep ever mentioned that you shouldn't use cruise control on a hill. What a scam. Not happy with my RAM purchase now.
