Electric-assist power steering, randomly in the parking lot the wheel will turn all by itself, one way turns easier than the other, sometimes you have no power steering and other times your steering wheel turns like butter, I live in the mountains with a very windy and dangerous roads, I've taken it to several mechanics finally one mechanic just unplug the wiring harness so there is no power steering. It is very scary to drive especially with a newborn baby. There are a lot of cars on the road with this issue I...

know 10 different people that have some sort of power steering issue. This is very dangerous and I'm surprised there is not a recall yet on it. I've had two friends that are close to me that have this issue as well, one friend wrecked his car the other friend sold it I believe to pick-n-pull so it would not hurt anyone, please help and maybe help save a few lives, thank you for your time and I look forward to speaking with you

problem but yet no recall we could find on this issue.My mother is on oxygen and if my car catches fire to do this and no one looking into this it can be far worse.Thier is another recall on front end suspsion that they are not willing to replace at this time.They tell me they are waiting to see if they come up with a better solution to fix it.Im going to mazda dealer tomorrow morning to explain to them what I'm explain to you and since this is a major safety issue if they refuse to do anything I'm turning this over to lawyer.I feel when I mentioned it to them the first time and they did nothing to find out what the issue was they have no intention of figuring this out but I will try again.The air bag was deployed when I bought it and the person said they were driving down the road.Thats how I knew about air bag recall .When I took car to be fixed the tech told me it didn't cover my seat. And never bothered checking it.

2005 Mazda RX-8SteeringSuspensionElectrical system

I had many recalls done last year. Now, today, oliver at mazda corporate said that joe machens dealerships aren't equipped to have done the work properly. Recalls: 16v793, 17v-354 & 355, front end stearing from inappropriate caulking of ball joint , engine replaced twice, oil mixing with coolant, again, and now my alarm goes off as soon as I start it. Joe machens told me to remove the battery. A new lithium battery is being developed by mazda because rotary engines can't use a regular battery. They had my car for...

six weeks last year, august, and kept yelling that they didn't have the new, correct parts. My stearing is difficult at times and they never told me about the recall concerning this. The seals deteriorated making issues. Now they are making new gaskets, rings, etc. To be heat resistant. They are fighting me, again, while they have admitted my car needs proper fixing with proper parts from inappropriate work done last year. One corporate worker said maybe a new engine should have been done with proper parts. Yet not at a dealership, at a mechanical shop that knows how to work on rotory engines. My car was parked in my lot. I had my oil checked to have fluids changed with valvoline because of their offer for 150,000 miles on engine if using their oil. I couldn't go forward with this because of the same issues . Oil foamy, alarm goes off, faulty light they knew about also. It worked before they did recall work on it. It is not safe for fire hazard, stearing difficulty, goes through a lot of oil since they worked on it. Ignition switch recall they never did. Were supposed to contact me when parts arrived. I will need to fax you paperwork. Many pages. Also shows how they x'd out one recall concerning gaskets. I couldn't check the boxes as I wished to report.

2004 Mazda RX-8SteeringElectrical system

My power steering goes in and out as it pleases; only works when it wants to and cuts up when driving and had to turn off car to make it work to only make it repeat again. Does this only when driving. And not safe for anybody who is dealing with the no powersteering issues or have steering but with many faults that can lead to accidents/death mazda fixed others by wire tapping all deleting the powersteering connections. But only having the issue later down the road they did this around february/march of last year and had in and out powersteering after 3 month of their repair.

I purchased my 2004 automatic rx8 in september of 2011. It began giving me trouble with the type of gas it took. I finally figured out that bp premium seemed to keep it from "coughing". I thought that I had fixed the issues and it drove fine for a good while. I changed the oil religiously at about 3000 miles or less. It would display the oil light after only about 1500-2000miles. I had a dealership look at it and they said the oil level was fine and they didn't understand why it had the light on. The oil light now...

comes on at just 300miles into the last oil change. In feb of this year is when the car started deteriorating at a rapid pace, and I was completely dumbfounded till I began doing some research and saw that many others have had the exact same issues I have had. For one- the ac never works correctly. I have to play with the knob for a bit to make it cool, and still even then it does not work. I am not able to drive it to and from the store now because I am worried it will not start back up. I always make sure the engine is warmed up and sometimes just leave it running instead of taking the chance of turning it off. The engine light also comes on and random times, and I was told that it was because the gas cap was not on tight enough. That is a lie, I always make sure to tighten it, and why would the engine light come on after the oil light everytime if it was human error. The car whines when at a stoplight or sitting for a brief period of time. It sounds as if it is coming from the front left side of the engine if you are sitting in it. No one knows what that noise is either. This faulty car should come with a warning on the front windshield. I am scared to drive it, I am scared to put my family in it, and I am disgusted with the way mazda decided to treat me when I called them to inquire about certain recalls. *Tr

I have been going back and forth to the dealer for my rx8's power steering failure while driving at various speeds. When it shut off twice of the many times, it pulled my car to the hard right and I almost ran off the road because of it. The dealership charged me the first time to replace the battery terminal because it was loosing power to the steering unit. Then multiple times later, hundreds more, they said that repairing the wiring harness connectors was recommended by their tech line and they said that may...

not be the last thing needed. First of all, the dealership, heritage mazda of lutherville, md, seem to be working hard on this problem, but this truly is a traffic safety issue and its costing me hundreds in a shot in the dark to fix the problem. Can you please look into this safety matter, even mike with the service department added that it was definitely a safety issue that needed to be addressed. On the rx8 club website, there are numerous complaints about the same power steering failure.
