What's wrong, in plain English

Chrysler is recalling certain Ram 3500, 4500 and 5500 cab chassis trucks built with a Cummins 6.7L High Output engine. While the engine is warming up to its normal operating temperature, it may not have enough warmup protection, and the oil film that should be on the connecting rod bearings inside the engine can be missing. That can damage the engine and cause a connecting rod to fail, which could punch a hole in the engine block.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to confirm your truck is included.
2. Contact a Ram dealer, or Chrysler customer service at 1-800-853-1403 (recall number W57), to book the engine software update.
3. The repair is free.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 20V511000.
