I purchased my 2012 CT brand new as my commuter car. I drive 90% of my miles on the highway. Car has 159k miles. Engine started stalling, rough idling, and check engine light (Code P0302) came on. I took into my local Lexus dealership and was informed it was an Intake Manifold issue (~$1100). Dealer replaced new assembly but issue persisted. Brought back to dealer for further diagnostic and was told it MAY be a leaky head gasket (~$4500) or will need a new engine (~$5500). Didn't expect this type of repair at 159k. Anyone else experience this issue on their CT and how they resolved?

 

Dang! that's alot of dough... I'd check other local shops as they tend to be 2-3x less costly than a dealer..

 

I agree w/ Miamiboy, I'd get an estimate/diagnosis at other places to make sure they know what the problem is exactly and to get the best price. You could also post on the Prius boards (priuschat.com) and see if anyone there has had a similar issue.

 

Can't believe I'm seeing engine failures on Lexus with 200k. I remember this would be unheard of, but now I'm seeing it a lot more often across all the models

 

If they made you pay for an intake manifold with code P0302 then you might want to get your money back under this recall https://www.clublexus.com/forums/ct-...cold-soak.html

Generally, diagnosing a misfire starts with plugs and coils, not manifolds or new engines. Go to another shop.

 

A generic p0302 code usually points to misfire in cylinder 2. Usually should start with plugs and new coil packs. Those usually last around 100,000-125000k.

 

Thank you everyone for the feedback. I'll check with a local shops to get an estimate and keep you posted on my situation.

 

Have same issue at 120k mi. Dealer wants $3k for head gasket and if head or block is "out of spec" a used motor for $6500. Found independent that verified gasket leaking cylinders 2-4. His charge is $1200-1500. Has access to new head if needed or used motor if block is cracked. I am checking the above link about money back because dealer replaced intake due to cel/trouble codes.

 

Update:

As this was my 2nd vehicle, I procrastinated on fixing my CT as Lexus was asking for $4500-$5500. With the recommendation of other members on this forum, I finally went to a local shop last month. They called and said it was a leaky head gasket and estimate was $2000. Much better than the $4500-$5500 so I proceeded with the repairs. The cars is now fixed and drives like new!!!! Sorry it took so long for me to update my post. Thank you everyone for the feedback and recommendations.

 

This may have been due to negligence on the part of the previous owner, not necessarily the CT's build quality.

 

Well now we know in 2019 the ct 200h engine cant live up to 200,000 miles or even 150,000 without taking it apart and cleaning it.

this for a car that cost so much, is barbaric

 

There's plenty of 3G priuses with over 300,000 miles and some even 600,000 miles.

you also don't have a transmisison to deal with, drive belts, or frequent brake changes. so pick your battles...

cleaning an EGR valve and cooler (or hell, just straight up replacing them with new every 100k) isn't all that expensive, or hard, really.

With cars, you're going to pay any way you slice it. There are no free rides.

 

Lexus CT200h is still "cheap to maintain" compared to other "Luxury brands".

I quote:

"Toyotas are famous for their new car care programs. Toyota purchases include ToyotaCare, which covers factory-scheduled maintenance costs for the first two years or 25,000 miles. Your oil changes, tire rotations, and brake inspections are covered.

Mercedes, on the other hand, offers a prepaid maintenance package starting at $769. According to MBUSA.com, the Mercedes-Benz website, the package will save you 30 percent on routine maintenance costs over three years compared to paying as you go. This one-time fee covers the car for three years or 30,000 miles.

Once these new car protections expire, the difference between maintenance cost grows. YourMechanic.com ranks the cost to maintain all of the major car brands. Mercedes, not surprisingly, is one of the most expensive cars to maintain — right after BMWs — at nearly $13,000 over 10 years. A Toyota should cost only $5,500 to maintain over 10 years. In annual terms, the Mercedes costs $750 more than the Toyota to maintain. "
