I've noticed that sometimes I smell something burning, electrical, coolant or something. My mechanics finds no leaks, but I checked once and the coolant reservoir was empty, find no leaks. Somehow, the passenger side rear mud flap came off and the trunk lid doesn't line up. It always looks like it's partially opened. When driving I hear and feel rattling sounds that sounds and feels like the front passenger side suspension or body panels. More like the suspension. The person I bought it from had it serviced regularly and had timing chain, o2 sensor, anti-lock brakes checked and fixed or replaced. They also had it completely checked out and anything wrong was fixed. It also gets very poor gas mileage. The steering also doesn't feel quite right, can't really explain that very well, other than it's no quite right. Also, for some reason the battery wouldn't start the car one day and we checked the battery and the cells were dry.

I drove into a parking spot, put my car into park & released my foot from the brake. The car rolled back as if it was in reverse. I applied the brakes, shifted the gear into drive & drove back up into the space. I put the car back into park, released the brakes, only to have the car roll back again. I pulled back up into the parking spot, shifted back into park & this time put on parking brakes. I got out of the car & went into the store. When I came back, my car would not start. Not only would it not start, it would not make any sort of noise (which is how I knew it wasn't the battery). I called for a tow & the tow truck operator was able to get it to start in gear neutral.

Since the 13th of november until november 22,2017 I have been having problems with starting my car. Two months prior I had just purchased a new battery so when the problem started I had the battery retested twice by two separated companies .the battery was found to be good and charging like it should.the alternator was good but yet the car continued to be jumped twice a day. I took the car back to the dealership it was checked out and we found the battery in the key fob was dead. Got a new battery for the key fob it work for one day. The next night as I prepared to leave home for work I had to jump start my car again and 8 hours later I had to jump start again to get home. On 11/22/17 I tried to start my car again it would not start everything on the inside was black nothing was lit on the instrumental panel and everything on the car is drained.

My car is a push start button. A few weeks ago, my vehicle would not start so had to have someone check it out only to find out it was the battery in the remote. And the 2nd remote had a dead battery. Fortunately it was in my driveway. What if this had happened when traveling to my hometown in canada and I got stranded in the middle of nowhere. How did this push button start get passed by safety. Am I the only one complaining about this. This is a serious matter. Is there a way I could have a regular key ignition put in to the car?

Took delivery of vehicle with 3 miles on january 27, 2016. Very next day the vehicle would not start without several attempts. On january 30 the vehicle was stopped in a parking lot while on errands and would not start after attempting for 15 minutes. Dealer service department advises that there is a drain on the battery when there should not be. Vehicle has been with service technicians for the 3rd day and they have yet to identify the root cause. The vehicle has 212 miles and I am fearful that an electrical problem will cause fire and severe safety issues.

2012 toyota avalon. Consumer writes in regards to vehicle radio sub-woofer recall notice issues. *smd the consumer stated on two occasions, he took the vehicle to the dealer regarding the issue. On both occasions, the dealer stated the had not received the means or the information as to how to correct the sub-woofer problem but he would be contacted when the remedy was available. On may 13th, there was a loud crackling noise coming from the rear of the vehicle and the radio stopped working. The vehicle was taken to the dealer, where the consumer told the service advisor, he believed it had something to do with the recall on the sub-woofer. The dealer called the consumer the next day, and informed him the issue was indeed related to the sub-woofer, because when the sub-woofer was disconnected the radio immediately began to work. A few days later, the vehicle would not start, because the battery was dead. The consumer believed the dead battery was related to the sub-woofer. The dealer disagreed with the consumers theory and stated the issue was a bad battery and alternator. The consumer went to get a second opinion and was informed the battery and alternator were working properly and the problem was due to either the previous dealer had disconnected the sub-woofer improperly or waited too long to disconnect it while they were trying to find the problem.

Car wouldn't start at shopping area - paid $5 for a battery jump - had car tested at local auto shop - said we needed an alternator but may be under warranty - went to eastern shore toyota - for $56.57 - yes we needed an alternator - not under warranty -cost $580 - take til tues - suggest we spend $100 plus and rent a car. We elected to take our chances and had the vehicle fixed closer to gulf shores where we are staying - cost was $396. We have never had an alternator go out after owning vehicles for nearly 60 yrs - let alone at 46725 miles and such a pricey car. We are considering the rav 4 for 2014 but this is giving us second thoughts.
