2017 TOYOTA TUNDRA Complaints

Flex Fuel Extended Crank when engine is cold. Have had into dealer multiple times and fix is temporary. Known issue with flex fuel Tundras that keeps returning

My 2017 Toyota Tundra Limited has 107,192 miles. I took the vehicle to Berlin City Toyota in Portland, ME for an oil change. The service technician told me that the truck has a cam tower leak. The engine is leaking oil directly onto the exhaust manifold. The service technician told me that if the leak gets worse the engine oil could combust and the engine would light on fire. I regularly have my truck serviced at Berlin City Toyota in Portland, ME, which is where I purchased the truck. I have documented with Toyota that the truck has been burning or leaking oil since it purchased the truck when it had 43,000 miles. No leak was ever found by Toyota until yesterday. The cost to repair this issue is $5600. No warning lamps or messages have ever appeared on the truck. Toyota says this is a common issues with the 5.7 liter V8 engine in the 2017 Tundra. I feel that it should be covered by warranty or a recall should be put in place for the cam tower leak on the Toyota Tundra being that the engine could light on fire with no warning due to the faulty seal on the engine.

The horn stopped working. I noticed this in an emergency situation. The horn which is a safety feature should not fail especially for a relatively newer vehicle with less than seventy thousand miles.

Our 2017 Toyota Tundra has been having difficulty starting, takes multiple attempts before starting. We brought it to Toyota dealership and had a diagnostic done. They told us we need new fuel pump and the ECM software needs to be updated. There is a know problem with Denso fuel pump system along with class action lawsuit. We were told that our vehicle is not included in that lawsuit. We were also told by Toyota dealership that the fuel pump is on back order and they are not sure when it will arrive. They said it could take months. With this fuel pump issue our safety is at risk because our vehicle could lose power at any time. There were no warning lights to alert us to this issue.

My airbag sensor is active. My vehicle only has 94000 miles on it. Power training warranty does not cover this failure. This happened when my car was parked and I turned on the engine and the sensor remains active.

Intermittent failure of the integrated trailer brake controller system. System indicates a frequent intermittent fault indicating a wiring or connection issue that disables the signal to activate the trailer brakes resulting in no trailer braking. Vehicle and trailer are available for inspection. I was travelling down a 6% grade mountain (Arizona SR87 MP224) an exhibited a loss of trailer brakes. Taking the trailer to the dealer on flat level service experienced intermittent loss of trailer brakes. Toyota Integrated Brake Controller (IBC) intermittently and randomly indicating a fault in the trailer wiring. •Rapid clicking of the IBC’s electrical relays. •In fault mode, the IBC disables the trailer brakes. •Sometimes the IBC works perfectly for miles and then goes into fault mode for an unknown reason. •Sometimes, the IBC goes into fault mode just plugging the trailer into the electrical socket without even taking the truck out of drive or depressing the brake pedal. •All external trailer lights include turn signals are functioning normally. Examination and diagnosis to date: •Toyota IBC was removed and replaced with a Tekonsha P3 brake controller using a Tekonsha wiring harness adapter to plug directly into the Tundra’s wiring harness used by the original Toyota IBC. The P3 is giving the error as brake circuit short-circuit, overload. •The travel trailer is a 2022 Jayco 212QBW, dual axle. •I brought the trailer to the dealer I purchased it from to have the brake system checked for faults. I’ve attached a copy of receipt from the dealer service department. In short, they examined the following and concluded the issue was with the Tundra. - The trailer wiring was physically examined with no deficiencies. - Trailer connected to the dealer's Chevy Silverado and driven around town with no faults. Toyota dealership claims they can find no fault with their tester. They would not use my 7-pin tester that also exhibits the same problems.

We were recently advised our 2017 Tundra needs a new fuel pump because it is not getting enough compression. We were told the 2018 Toyota Tundra and many other vehicles made by Toyota have been recalled for this exact same issue we are having but there have not been enough complaints about the 2017. Well here’s a complaint. I have to pay for a fuel pump known to be bad by Toyota but since enough people haven’t complained about a problem they are aware of isn’t fair. Please put my complaint in so something might be done about this.
