problem #11

Dec 062013

Focus 4-cyl

  • 58,000 miles


My son was driving in the car pool lane when the car came to an abrupt stand still. It turns out the compressor failed and threw its parts all over the engine compartment damaging parts of the engine. When the engine failed, he lost braking and steering abilities. Compressors do not last forever. However, when a compressor quits working that should be the extent of the failure. This compressor failed and basically came apart. The car not working in the middle of a car pool lane put my son and his wife in danger as there was no where to get out and no way to move the car.

Focus 4-cyl

  • 46,220 miles
While driving at around 15 mph, my car started to accelerate even though my foot wasn't on the gas. I looked at my dash to confirm cruise control was not on (it wasn't) and noticed the service engine light was on. If I didn't touch the gas or brake the car would accelerate up to 30 mph and stay constant at that speed. I rode the brakes to the local Ford dealer. They inspected the car and determined the issue was the throttle body sensor, and said I had to replace the entire throttle body. Cost was $400 for the part and $230 for labor. This was not covered on the powertrain warranty I still have.

Focus 4-cyl

  • 78,000 miles
On March 5th, 2013 I was traveling home at 65 mph and the car jerked for a brief moment and no warning lights came on. Traveled another 20 miles and again it jerked this time the control module/transmission light (wrench icon) came on and the car began to go into limp mode. I was able to pull off the freeway and shut the car off. After a few second started it back up and reset the computer. Was able to get back on the freeway and make it the next 30 miles home and another 10 miles the next day to the dealership with no issues. I was informed on March 6th that the throttle body was bad and has to be replaced. This seems to be an issue with the 2010 Ford Focus her in reading the other complaints. Current mileage on the car is 78,000 but entire engine was replaced at 58,000 miles (under warranty do to a timing failure at 65mph destroying the motor!!!

I have a 2010 Ford Focus that has a "raw gas smell in the passenger compartment and in the trunk" area. This smell is not constant, at times we smell it for several hours and then at other times no smell. But mostly we smell raw gas. I've taken it to the dealer's service department twice. They could smell the fumes, when I brought it in, but could not find where it was coming from. The vehicle was left there for a couple days to be completely checked.. they were not able to find nor fix the problem. The "gas fumes give me headaches when driving" the vehicle also I worry that this "raw gas could cause a fire."

  • Automatic transmission

The contact owns a 2010 Ford Focus. The contact stated that coolant was emitted through the air conditioning duct and leaked inside the vehicle. The failure caused electrical problems in the vehicle. A representative was sent by the manufacturer to install a coolant fan motor on the vehicle. The contact stated that after the installation, the failure persisted. The manufacturer was notified who offered no further assistance. The failure mileage was 28,000...updated 09-26-12 the consumer stated when coolant came out of the airducts it got on the consumer's face. When the consumer applied the brakes the vehicle went in reverse. The brakes were applied again, the consumer hit the steering wheel and the seat belt unbuckled. The coolant that came out of the airducts also reached the interior floor and behind the console. Other issues with vehicle are the tires that have always looked worn, when the brakes were applied the vehicle would accelerate, rpms would increase and engine revs, toxic and burning wire odors, excessive heat from the engine, metal grinding sounds from under the hood, vibrating and rough riding, the trunk opens on its own, compressing sound while air condition is running, windows were icing on the exterior of driver and passenger windows, and rust on the ignition.

Focus 4-cyl

  • 8,000 miles
Focus would lose RPM's when idling, would almost stall. Took to dealership and they first said it was due to tank being topped off and said it was corrected. Problems still existed so took back 2 more times and finally said it was a sensor. Replaced and worked fine for couple of years. Now it is having same problem, seems the sensor for the idle is not made very well. Have appointment scheduled to take in for repairs.
