2014 Mazda CX-5: multiple warning lights

Filed Nov 1, 2019 · 106,000 miles · MN

My vehicle will not shut off completely. The battery to the car and all of the dash lights stay on when I turn the vehicle off. This problem has been happening for over 6 months and is happening more frequently. I discovered that you have to jiggle the shifter in park many times before trying to shut of the engine again. At times I have to do this process 5-6 times to finally get my car to shut off which is very frustrating. I have found many people on chat forums with this same exact problem on their mazda cars. It is because of a defective shifter switch part kdyo-46-040. My mazda dealership is going to replace this part next week for $250. When I called mazda corporation they will not do anything to compensate for this expense because my vehicle is over the warranty. This is unacceptable since mazda has installed a defective part in not just mine but many peoples cars.

My wife complained about how she tried to accelerate and it didn't work one random time while she was driving. I took it around the neighborhood to test it out. I wasn't even out of my block before the incident happened. I was in the middle of a turn and everything just stopped. I was going less than 10 MPH when it happened. Several lights came on on the dashboard. The traction control light, the at light, the TPMS light, and the check engine light. Something bad happened and this could have killed someone had it happened on the highway. I turned the car off and on and now only the check engine light is on. I was able to drive it again at that point.

When I start the car all the dash lights illuminated and stayed on as I drove the car. When I turned on the right turn signal all the warning lights flashed rapidly the navigation, electrical system shut down and the car started to die. The service engine light stays lit the warning about a power steering failure, brake failure and keyless entry problem, ABS, speed monitoring tire pressure all comes up in the warning area. The power steering does fail making it hard to turn. In doing research on the issue it comes from a faulty ground cable issue on the right side of the car. I have had this occur 3 different times now on this car.

No issues leading up to this point with my cx-5. Went to start the car and all the dash lights illuminated and remained on. As I began to drive, I attempted to use the right hand turn signal and the warning lights flashed rapidly as the electrical system, bluetooth, navigation, and entire engine shut off. I stopped the car, put it in park, and tried restarting. When it did, half of the warning lights were on in park, including the service engine light, and when put in drive the rest of the lights came back on. I tried the right signal again (in park) and the same issue occurred, with the end result of the engine turning off. As I drove with these lights on, new warnings came on and off, including loss of power to my steering(making it more difficult to turn), ABS, speed monitoring, tire pressure, blind spot monitoring, horn, and basically anything else controlled electronically. I ran the codes and got long list, with most of them being connected to loss of communication. Some codes were: u0121, p0500, p0685. I took it to the mazda dealer, and after 2 hrs of diagnostic there were unable to find the problem and said they would need more time (and money, obviously). From reading other blogs/comments with the similar issue, seems to be a faulty ground wire. This is something that is extremely dangerous and seems to be occurring a lot in this model. Mazda needs to address this issue asap

About an hour into my commute from work, stopped at traffic light. Accelerator didn't respond after several attempts to reach full speed. Maximum speed reached 5-10 MPH on a 50 MPH road. Several warning lights displayed immediately and was able to safely pull over onto side road. Restarted veh and engine light remained on; accelerator responded normal and was able to get home cautiously. Veh was taken to service next day, advisor explained issue has been alerted on service bulletin. Currently waiting on transmission parts.

The first incident was when I started the engine, the engine warning light and all other warning lights(sbc, ABS, etc.) came on. I called the mazda service for an appointment several days later and I went to service for a problem, the guy who in charge told me since the engine light came off we can't do anything. So they just did change my oil and left. Second time happened with same problem, I went to my buddy(mechanic) at other car service he told me the guy told me was wrong because every car has a computer chip that records every problem. Anyway, my buddy diagnosed my mazda cx-5 and told me that my car has a bad or weak transmission signal that caused the engine shut off so I went to mazda service for second time with same problem, they diagnosed and told me that it was the weak transmission signal so they had to reprogram it. On april 26, 2014, approximately 5:00am I was driving on hwy. About 60 MPH and sudden all the warning lights include engine light came on but this time engine didn't shut off but transmission had no control to itself. I was so scare and all my friends who were with me got scared also because it was raining hard early morning. I had to pull over to service road then I made a completed stop but the transmission didn't start with 1st gear. It felt like it stuck on 6th gear so I had to press accelerator all the way to kick to it. This is the third time happen to me I don't feel comfortable with my cx-5. I took it to the third time service for same problem on april 28, 2014. I've never had this kind of problem for any other cars that I've ever driven specially a brand new car. Anyone who has bought cx-5 have same problem should make a complaint.

Upon entering the highway a car came up on me very fast, whereupon I floored the gas pedal. The car jetted forward to about 65 MPH then suddenly lost all power; like it was functioning on one cylinder. I had to pull over and coast down to my max speed of 5-MPH. Even though the pedal was floored I could not get above 1000 rpms and 5-MPH. Various warning lights came on, including the tcs and engine lights. All warning lights remained on without flashing. Once I got to a safe place I shut the car down and within one minute restarted it with no sign of a problem. I drove over 100-miles today and nervously had to passe someone, but without problem.
