Last Thursday, June 6, I traded the 2018 Cruze for a 2017 Ram 2500 with the 6.7L Cummins and 24,007 miles. It’s still in manufacturer bumper-to-bumper warranty until 36,000 miles (and powertrain to 5 years / 100,000 miles).
Loving it so far. On the third trip up Sedillo Hill west of Socorro, at the top of the hill the check engine light came on. When I got home, I scanned for codes and got P2281 (“leak between MAF and throttle body” — which, translated into Cummins terms, means a possible boost leak somewhere between the air filter and the intake, so it could be any number of pipes, boots, or the intercooler.)
I cleared the code and drove it again, and it didn’t come up after another trip up the hill. I’ll keep an eye on it.
