Top problems in owners’ words
Verbatim from NHTSA complaints, newest first
Electrical system
308 reports7 crashes12 fires3 related recalls
“Vehicle shuts down and looses all power and battery controls without warning. My [XXX] daughter was driving the jeep when this happened. Was unable to get vehicle into N for over an hour. Fuses and relays inside the under hood fuse block were extremely hot. After finally getting it into N, we removed from the travel lanes of the 4 lane highway. I had jeep towed to house and waiting to hear back from dealer as to when I can have it towed in.”
Steering
255 reports2 fires1 related recall
“I was driving on interstate going 75 mph in the passing lane when my steering wheel locked completely up. My car started drifting to the right, but I was unable to turn the steering wheel. I almost hit the guardrail. The car is now being towed to Jeep dealership for fixing of the active recall.”
Engine
223 reports4 crashes10 fires1 related recall
“At 47000 miles the oil cooler cracked, although the technician stated it did not cause the crankshaft: harmonic balancer pulley to be damaged, the mat issue did occur and documentation from other sources state one can cause the other. Replacement cost was substantial for a low mileage vehicle. Documented issues with the oil cooler failing on Jeep Wrangler JL, specifically the 3.6 L engine is easily obtainable. The dealership admitted replacing a lot of them. This is a manufacturer defect that should be resolved.”
Suspension
181 reports1 crash
“On the highway, at Highway speeds of 70 mph, going over small bump my jeep goes into a death wobble. Both tires bouncing erratically steering wheel racing back-and-forth. To stop the death wobble I Have to let off the gas and slowly break to a complete stop before the death wobble stops. The frustrating part is, the Jeep Wrangler, is only five years old, and it has never been off-road, and has less than 28,000 miles on it, not to mention how dangerous the situation is. I have had this happen 6 times.”
Power train
149 reports5 crashes5 fires3 related recalls
“While towing a utility trailer on the highway, the vehicle suddenly lost acceleration and could not maintain normal power while the driver was attempting to pass a semi-truck. During the incident, the semi-truck contacted the trailer and shredded one of the trailer tires. Three occupants were inside the vehicle. No injuries occurred, but the incident created a serious risk of a fatal collision. The vehicle has repeatedly displayed “Service Electronic Stability Control” and other warning lights, together with loss of power and transmission hesitation/slipping. The same concern has been reported to the dealership during approximately three service visits. The dealership previously replaced the air filter and attributed the warning lights to it, but the condition returned. Dated videos show the warning condition before and after that repair. The vehicle is currently back at the dealership for the recurring safety concern.”
Fuel/propulsion system
116 reports1 crash5 fires
“When driving about 50 miles per hour on the highway, it felt like my engine suddenly gave out and my dash turned off. When it came back in, there were multiple indicator lights and a message that read "Pull over safely and shift to Park." I did just that, but after that I couldn't get the car to turn back on or shift out of park. I had to have to towed to the dealer and it has been there since 10/13.”
