Toyota Avalon loss of power problems

Filed Nov 28, 2022 · Fuel system · PA

Intermittently, unpredictably, for several seconds at a time, the engine almost quits, especially when accelerating So far, it has not happened in heavy traffic, but if it did, it would create a possibly major safety hazard. I have not taken it to a dealer yet. Just learned about the fuel pump problem that is associated with my 2018 Toyota Avalon. Plan to contact the dealer tomorrow. I have not seen any instrumental warning or notification. There is no warning that the engine is about to lose power and so far the engine has not stopped, but recovers to normal operation.. This has been occurring over the last couple of months. I fear for my wife's safety so that she will be unable to drive this 2018 Toyota Avalon 3.5L sedan until it is repaired.

The engine has quit while in traffic several times and the check engine light and the skid control lights are the only lights lit on the dashboard. Once the car comes to rest and one waits 3 to 5 minutes, the car will restart. We have taken the car to the dealer twice, ( each time the had it for nearly a week) and they could not find the problem. This is a very serious problem because the engine stops without notice causing loss of power steering and total loss of control. The lights for check engine and skid control are sometimes on when this happens, but not always; and the fact that these lights are lit does not predict this event happening.I think there might be a sensor in the engine that is faulty.

At approximately 42000 miles with no significant issues and no front end damages, the steering failed as I was driving at highway speed (70 mph) on a 2 lane road approaching a 90 degree curve. The power steering warning light and a separate triangle warning light appeared at the same time as I felt a pop and lost power and response in the steering wheel. Thankfully, I have driven heavy power equipment in the past and was able to control the vehicle to the shoulder and there was no surrounding traffic. I was able to proceed to my residence at a slow speed on the road shoulder with no power steering and an almost unresponsive steering wheel. After being towed to the local dealer, it was determined the torque sensor failed and the entire steering column required replacement. I had no warning of this impending failure. The airbag recall was done on this vehicle by the dealer several weeks prior to this with no reports of an issue. It is unknown if the airbag recall service impacted this catastrophic failure. The dealership was in possession of the faulty part on 8/27/2021, when the repair was completed. I understand there were previous recalls on Avalons pre-2005 for this issue.

At 3600 miles, while driving on a city street, can check engine light came on plus all the other warning lights and malfunction messages about every sensor in the car, car lost power and acceleration, engine starts sometimes only. Dealer diagnosis was a full tank of e85 gas, gas station does not sell that and no any other complaint of e85. Did my own testing, doesn't seem like any ethanol in gas. I saved all the gas for further testing. I complained to toyota corp but they stood by and supported the dealer diagnosis. Gas station insurance carrier denied the claim. Even if it was e85 gas, this shouldn't have all this impact on this avalon and its computer system.

On june 7, 2019, I was driving the avalon, the engine suddenly stopped while I was driving the vehicle on city street. With the loss of power steering and brakes, I was traumatized and did my best to guide the vehicle to side of the road. I had the vehicle towed home and hooked up to a code reader, which yielded codes p0345, p0300, p0302, p0304, p0306. We did further diagnostics and discovered the 3 bolts that hold the variable-valve timing (vvt) gear to the intake camshaft came loose, these bolts are supposed to be temper-resistant and never be removed which LED me to believe the result of engine dying is caused by serious manufacturing and design defects. Please refer to attached three pictures showing 3 bolts laying next to vvt gear, vvt gear loosely held on and the vibration of bolt left cutting mark on the gear, and all intake cam rockers falling out. I did more research and concluded the root cause of engine stopped while the vehicle is being driven in our avalon is identical to toyota safety recall 13v‑395 in lexus vehicles 2006 to 2011. Please find attached two documents, rcrit-13v395-3180.pdf on recent recall for toyota safety recall 13v‑395, rcdnn-13v395-1839.pdf on defect information report from toyota to the federal safety agency on lexus intake-side variable-valve timing (vvt) system part 573. On june 27, 2019, I called stevens creek toyota and toyota hq and logged case [xxx]. I was informed by toyota there's no recall for avalon with the VIN, and the vehicle had no factory warranty (currently 153k miles), and no extended warranty with engine stall for avalon. As a result, we need to repair the vehicle in our own expense which requires engine rebuilt as engine stall has caused severe damage to the vehicle. I was appalled by toyota for lack of initiation to address the safety risk in our avalon and we appreciate your thorough investigation in this matter.

On may 28, 2016, me and my 4 year old toddler were traveling on the interstate in our 2005 toyota avalon (approx. 142,000 miles) when it suddenly loss power. The dashboard lit up and heavy smoke began pouring from under the hood on the right side of the car. Luckily I was able to coast to right side of the road and stop the vehicle without getting slam from behind on the interstate. The vehicle had just been serviced on 05/18/2016; with no issue prior to traveling out of town for the holiday. After a dealer full diagnostic was completed; it was determined that the head gasket blew and that along with the engine had to be replaced. This was the second opinion. The previous dealer full diagnostic was performed on the car in 11/2015, when engine light came on and an "system too lean code" appeared. At that time, the following items were removed and replaced. Intake manifold gasket, throttle body gasket, plemum gaskets and spark plugs. Other than that, the car has have routine service and maintenance performed on a regular basis. How does a car with an excellent service record develop an issue of this nature without any advance warning? There was no check engine light, the car wasn't running hot. There were no strange noises, thump, rattles, etc. I purchased the vehicle based on its ratings and reliability factor. --as I started to do a little research, I am seeing that this is an issue with this vehicle along with the toyota camry. Why isn't this reported as a know issue with this product. I just get sick knowing there was no light sensors or anything to warn of an issue. We were very fortunate not to get struck from behind travel at such a high rate of speed on the interstate.
