While traveling north on us 221 from bent mountain, va to roanoke va my hydralic steering totally failed. As I travelled a short distance my brake light warning lights, abs light, other brake system light, battery light and air bag warning light came on. I looked at the engine temperature guage and the temp was normal. I pulled into a parking lot, raised the hood, checked the fluids in the engine compartment and reentered the car. While sitting in the drivers seat I heard a loud explosion, looked forward and noted...

thick steam coming from the engine compartment. I turned the engine off, exited the car and when the steam dissipated I noted that the cooling system filling/overflow tank was split in half damaging a protecting cover on the firewall and sprayed a building wall and window with engine coolant 10 feet away in front of the vehicle. I had the car towed to martin's german service in cave spring, va. Because the closest dealership in located in north carolina 150 miles away. Due to service volume they will not be able to evaluate the problem until 24 may 2016.

will not fix these issues unless you make them recall vehicles with multiple small problems ( not just one big problem) - this model has 73 tsbs that dealers charge you to fix even though the problems are known and dangerous issues. In my mind, many small problems can be more dangerous than a few big ones - steering, door locks, cooling - not good. This is an old car but these problems are old too - known tsbs should not be subject to warranty time frames, they are still dangerous after the warranty expires. When these cars are routinely serviced, these known/dangerous issues need to be corrected or the cars should be taken off the road. I used the date of the last incident, not the first one. Thank you. *Tr

8/13/2014- I was stopped at a stop sign in a mall parking lot and smoke started billowing out from under the right front side of the car and at the same time started coming through the vents into the cabin of the car. I tried to shut off the car, but it would not turn off. A bystander came running and opened the hood, smoke poured out, told me to call roadside assistance as he was opening hood and then told me to hang up and call 911 that my car was on fire.

was too much smoke. The engine fan was still running. Another passerby had an commercial extinguisher and emptied it on my vehicle. The fire dept. Was pulling up as they were trying to push it aside, the car re-ignited and it took the fire department approx. 15 To make douse the fire without it re-igniting. All of these people looked my vehicle over and could find no reason for it to ignite. I purchased the car used about 4 weeks ago and have put about 3000 miles on it without any issues. My insurance company had it towed to a mechanic down the road and they are to contact me tomorrow to see if they can see why this occurred. Luckily, my daughter and I were able to exit the car and be in an area close to the fire department and good samaritans...Updated 10/06/14 *bf *tr updated 7/15/2015 *js

problems with the water pump leaking and catching fire in the engine. I called mini usa and filed a case,and they promised to respond within 3 days. However, they did not only until I called various times and finally was able to reach a representative. James informed me that there was no way to evaluate the mini cooper was as at fault and only tried to sell me a new car. I am very disappointed with mini cooper's customer service and lack of support. My car is now a complete loss. *Tr

While driving on the freeway, on a slight incline is when I noticed the rpm was high and the speed reducing. (Along with some crackling, rough noises from the front end of the car) I let off the gas pedal (lowered the rpms), tried to accelerate but the car wouldn't regain speed the car eventually reduced driving speed to 30mph with rpm at 5. I moved over to the shoulder of the freeway and waited for help. With a child in car. Transmissions should not fail on a vehicle at 50,000miles. Very scary situation. I hope this issue with this make/model/year vehicle is addressed. That issue could seriously harm alot of people I have read too many similar stories online. *Tr

The transmission in my 2003 mini cooper died at 59,000 miles. I had to replace the transmission, same as numerous other mini cooper owners have, at a cost of about $7,000. I was told that the cvt transmission in the 2003 mini coopers were defective and nothing could be done to repair it. Mini cooper has not responded to the numerous complaints by its consumers and has not offered to help pay for the replacement transmission cost. *Tr

Turning from a left hand turn lane on to a side street as I have done at least 4 times a day for over 10 years, I lost all power and the ability to control the vehicle. In the middle of the turn the loss of power, the loss of steering, and the loss of brakes caused me to run into the curb. This accident resulted in the right front wheel and assembly being replaced.

mini dealership that there was no fix for this problem. I've had too many near accidents because of it. Going back as far as 2005 I have complained about my steering and the noise it makes. The whole steering unit has been replaced 2 times, yet in 2009 I experienced a total loss of power while traveling at speeds of 65 mph. The power loss was electrical even though my engine was still running. The final outcome was mini replaced the alternator and battery. I've complained time and again yet with no help unless it's coming out of my own pocket. Since owning this mini cooper s I've spent nearly 6000.00 In repairs. Because of the interdependent nature of the asc/dsc on the vehicles braking, electronics, and even starting acceleration from a stop; has this feature been properly studied as the culprit for the many and varied problems this particular car has? In the uk there is a blog called watchdog that has 180 people who posted between february and april 2009 that all had the same problem with the power steering that I and hundreds of others have reported. How can such a serious problem go unresolved for so long. There is no doubt that this problem alone falls under the united states code for motor vehicle safety (title 49, chapter 301). *Tr

I own a 2003 mini cooper automatic and I've already had to have the power steering pump and the cooling fan replaced twice, and now, only a year later after my 2nd replacement and a few thousand dollars later, it needs to be replaced for a third time. The care only has 80,000 miles on it. This is costly and a safety issue for drivers. I will never buy another car by mini or bmw. *Tr

2003 Mini cooper s with power steering failure. Power steering goes in and out. Car radio turns on when car is off and no key is in the engine, causing battery to drain. Once my power steering went out when I was leaving a parking area causing me to hit the car in front of me. I have not repaired damages. I have however replaced the engine due to faulty wiring in aprox 2009. A fuse that runs everything for cooling blew and gave me no warning the engine was overheating. *Tr

I have owned the vehicle since its purchase brand new in march, 2003. When the engine is warm and starting it up after having been shut down for up to two hours there has always been a minor, intermittent problem with a rough and surging idle that oscillates between 1050 rpm down to 400 rpm then back up then down which lasts for about 30 seconds before settling down. As the vehicle has aged the problem has intensified to the point that the engine sometimes stalls. The symptoms are similar to those as noted in...

nhtsa item #10009756, service bulletin #110104 (rough idle, stalling). Lately it has now even begun to occur when stopping quickly causing the engine to almost stall. If it were an emergency situation there would not be enough immediate power to accelerate. The dealer has been shown the problem but has failed to rectify. The only investigation they do is to make sure the software in the vehicle is the latest release. *Tr

I purchased my '03 mini copper s with 49k from a honda in mechanicsburg, pa dealer in august. In december, I purchased tires and then went to a self-service carwash afterward. When I got home and before I put it in the garage, I took out the hose and washed off the wheels and under the car. During the process there was white smoke, which I thought was steam from the water hitting the manifold. I put the car in the garage and later when my wife came home she commented on the smoke and mist in the garage (it...

was quite cold that night.) The next day when I pulled the car out, the steering was very stiff and I only drove it out the driveway and on the road before I realized the power steering was completely out. I drove it about 15 miles to the dealer after checking fuses and determining that the problem was beyond my mechanical skills. The power steering pump, fan and harness were replaced along with the battery (shorted out). Insurance adjusters from hondacare (extended warranty), state farm insurance company (my comprehensive insurance) and the dealership determined that the power steering pump had caught fire. Their conjecture was that I had put out the fire with the hose when I sprayed under the car. Honda care paid $1999 from extended warranty for the power steering pump, battery, power steering harness and fan. A total of $2700 additional from state farm comprehensive insurance (hondacare extended warranty would not cover harness, towing and diagnostic work from the mini dealer in maryland, etc because they were the result of damage caused by the power steering pump fire); state farm insurance was exceptional and covered the difference with comprehensive covered. The parts are not available at this time but I was told that there are reports including pictures from adjusters at hondacare and from state farm insurance. *Tr
