Two problems related to engine rattling and whining sounds have been reported for the 2010 Jeep Wrangler. The most recently reported issues are listed below.
Engine started making a rattling noise at 54,200 miles. No engine lights or oil pressure indicators. Brought in to have checked & found to have no engine oil, low engine coolant. There was enough damage done to the engine that I'm having to have an entire new engine installed as it was more cost effective than replacing the individual parts. The dealership received a new engine & installed. This one was deffective & had to wait for another one to be received & installed. Thanks,.
Initially, after moderate acceleration from a stop to 35 mph, engine elicits a new loud rattling sound. This sound directly corresponds to engine rpm dramatically increasing with rpm over 2000. When decelerating from a higher rpm, the sound increases until moderate acceleration is again applied. The sound emanates from the upper right engine area at all times during engine operation. This sound first occurred within one week of a dealer oil change and continues unchanged after 1400 miles. There is no noticeable change in vehicle performance. Gas mileage efficiency has decreased by one to two miles per gallon.
