2014 Ford Explorer Vehicle speed control Problems

“About 20-30 seconds after hard acceleration the cabin fills up with the sulfur smell from the catalytic converter. Have had it back to the dealer to perform the TSB but now it seems to be even worse. They have told me that the factory will contact me when they find a solution to the problem however no-one ever has. I cannot safely drive the car like this. The stench is overpowering.”

“Strong exhaust smell anytime engine accelerates, such as downshifting when going over an overpass on an interstate highway. Not hard acceleration really. I have researched, and know this a common problem, and has been since the 5th gen explorers came out. I know it has been brought to the attention of NHTSA, and I am just registering my complaint hoping you can get the problem resolved. Thank you.”

“When accelerating to pass a dangerous truck (58 MPH) strong fumes comes inside the cabin, acceleration took 8 seconds, instantly we start coughing and get watery eyes, our year old baby start crying showing symptoms of distress, we tell this to sales person, which quickly told us the story that this happens with new cars.. Supposedly new engines should not be highly accelerated. Naively we believe this and decide to give it a few days? …”

“When accelerating or doing freeway speeds the smell of exhaust circulates throughout the car. It is so bad that we have to roll down all the windows. This has caused drowsiness, headaches and our young granddaughter to have an asthma attack. The vehicle has been taken to 2 different dealerships numerous times and they both say that there is nothing wrong with the vehicle and that the smell is not abnormal. They claim that the car is not broken in yet and that the catalytic converter needs to burn off.”

“I rented a nearly new Ford Explorer limited awd in milwaukee, wi. I had been considering purchasing this model so I was pleased to be able to drive one for a few days. Every time I accelerated hard (wot) the cabin would fill with exhaust fumes. This occurred even with the AC in recirculate mode and without any other vehicles nearby that would have produced the odor. It was strong enough that we opened the windows to get fresh air. After the 2nd time of this occurring, I did not accelerate hard again as to avoid the problem. …”
