Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2014 Toyota Corolla owners, lightly cleaned up (personal details are redacted by NHTSA).
We was on Highway and a Buck jumped out , my passenger was freaked out knowing no Air Bags deployed. I was escorted home by police and Contacted Toyota ,they sent a [redacted] to come take my sensors off the car and Never contacted me again, told me to sign into Toyota page and they'd get back to me. Now my car just sits Smashed in Garage, it was in great shape before and I was gonna trade it in.
The AC compressor is failing as it's blowing hot air at idle or when the vehicle is running at 20-40mph. During Texas hot summers, baby & toddlers are at risk for extreme heat as the AC blows hot/warm air. The problem has been reproduce at an automotive AC shop where they have inspected the AC for leaks, vacuumed refrigerant and replaced refrigerant. Still same issues without any leaks. Police or insurance has not been involved. There are no dash lights when this happens and the issue happens daily which started 3 years ago. The vehicle is driven less because of the issue. There is a TSB T-SB-0086-14 that says this is covered within 36k mile warranty or 3 years. I bought the vehicle with 48K miles and about 2 years later the AC blows hot air at idle.
Vehicle stopped accelerating while on highway leading to dangerous slow down with 2 little kids in the car. Car would no longer accelerate despite engine running. Check engine light turned on. Toyota dealer ran diagnostics and found vvti actuator had internally failed. This was a very expensive replacement. I worry that a previous recall for ECM module update came too late before damage had already occured to the vvti actuator prematurely. Car is well taken care of and only 100k miles.
I was going to work, my check engine light came on as well as my track off light came on and I noticed that my engine smelled burning, it was not holding my coolant in my radiator. The dealership said I bought the car as is. I had only had the car for only 7 months. I feel like the sold a car that may have more issues.
This am I hit a deer on the way to work head on at 65-67 MPH and not one air bag deployed!!! The entire front end crumpled to the windshield area and the radiator and parts torn lose to the top of engine and not one air bag deployed. Everyone at the wreck could not believe it and now I am terrified of the car if direct contact at that speed does not open the safety equipment what will? This car is not safe.
My vehicle has been taken to the Toyota dealership at least 12 times since purchased. It has already had a rear seal leak, back brakes and front brake work and rear brakes replaced. The timing chain cable was leaking oil and they replaced it. It has not ran the same since. It continues to hesitate to almost stalling out during takeoff at red lights and intersections. It's acceleration is terrible even for a 4 cylinder. We have been cooperative for the 3 years with Toyota, but now that the warranty is void due to the 3 years, and not the mileage, we no longer receive such a helpful conversation with any of the managers there. The car is still under 25,000 miles, and has been a total lemon to us. We've exhausted all hopes of them fixing the real problem since they continue to claim that they couldn't find any such problem in the acceleration issues and stalling in the intersections. …
I have attempted for the last 14 months to get a noise fixed when my car starts up. I have made 10 repair efforts with Toyota and Toyota corporate. I have filed lemon law on my car and Toyota has sent me letters twice stating they have reviewed my repair orders, inspected the car, and it is working as designed. While the letters are being sent to me I have open appointments to get the car repaired for this issue. I called the Toyota field rep and he stated that my case is closed because they do not know what is wrong with my car. The noise happens when starting the car after it has been sitting for at least 20 minutes. It sounds like something is broken inside the engine. On the last trip to the dealership Toyota replaced the starter on my car and it did not resolve the issue. …
I was pulling into my driveway at 1 mile per hour and I put my foot on the brake to stop my car and it wouldn't stop! The engine revved up and my car went through my fence into my backyard. I tried in vain to stop my car, I kept pressing down on my brake, (5 times) with no success. I finally put my automatic transmission into park and it finally came to a stop. I was extremely shaken up since I thought I was going to die! I checked my car for damages, I noticed that my passenger side view mirror was damaged and there was other damage under my car. My car is only 3 months old and has 950 miles on it. I have been driving for over 30 years and I have never encountered anything like this. This happened on November 27, 2014, thanksgiving day at 10:00 am. The weather conditions were cloudy with a temperature of 34 degrees.
