Everyone with oil temp issues

ZYUL8R

I have noticed my oil temps above 240 during normal driving. This is fustrating. This car Needs a cooler!

Glad I decided to check out this thread... I figured it was a "track-only" problem until this thread got so long. Wanted to say thanks to all the guys chasing down this issue. I'm currently shopping and as yet, the 370 is the only car that has made me say "Wow, thats really cool" when I saw it. However since I'd probably be putting 15k / year on it and would want to keep it a long time, the oil temps getting that high during normal driving is somewhat troublesome.

I wanted to second this comment. I just test drove the 370z this past weekend. It is a very fun car to drive and is still my #1 pick for my new car. However, I really want to have some piece of mind that while I own this car in Florida, that the temps are not going to be an issue.

I'm currently going through cooling system problems on my current ride. Don't want to buy a $30,000+ sports car that constantly runs on the hot side!

Hope Nissan does something about this.

Just curious, but can I not have the dealership put a cooler on or no new car sale? Is that not really an option, even in these hard economic times???

semtex

Yeah I did mine a month ago. Now whenever I get one of these surveys, I check to see if there's money in the envelope before I toss the rest of it. I submitted the JD Power one, but I'm not doing any more. One is enough. I got hit with like 5 more after JD Power.

Anyone driving the 370Z in Texas?? I assume the hot weather will push the temperature up.

I sent e-mail to Nissan regarding this issue and told them I'm considering the car, but the high oil temp is A HUGE CONCERN to me. I will see what they say.

There are a few at least, the worst I have seen is 220 in traffic but I am still breaking my car in. This week in Houston it is suppose to break into the lower 90s, so we will see how even tamed driving does.

Yeah--I grew up in Houston and just recently moved to Austin. It's 90 here today. I'm hovering right above 230 driving 10 miles to/from work running the rpm's up around 5.5K. I filled out my JD Power survey last week and unloaded about the oil temp issue as well.

spearfish25

I think Semtex or Wstar noted the engine temps seem to settle down slightly as the engine breaks in. Lately I've found the car sits at a happy 210-215 during most driving in 60-70F weather. Unfortunately, it's not enough to solve the temp problem with more aggressive driving in hot weather.

wstar

That was my theory, but I'm at 4K now and I'm starting to think break-in isn't going to change much.

My general mood on the oil temp issue changes from day to day. Every day is a new learning experience about our oil temp issues. This evening was particularly hot and muggy compared to recent times. On my evening drive the ambient air temp sensor on the car was reading 86F at about 7:45pm, and the car pretty quickly got up to 220 just cruising around very lightly. Got it up to about 235 by pushing the revs a little on the highway, but I didn't bother really going after the temp testing this evening. Took it quite a while, perhaps 7-8 minutes or so, to cool back down to 200 idling at a gas station with the hood popped before I shut it down (not that that's really necessary at 235-ish, I was just seeing how easily it came back down).

I suspect in the next few days I'm finally going to get to see how my oil temps do in some much hotter conditions when driving aggressively.

Engine Overheating Resolution

It is important in prompting Nissan to properly act on this issue—especially with the advent of summer fast upon us—that we up the ante on how to make our efforts count.

The Distinction:

Clearly this is an issue of life/safety as premature engine failure bought about through engine overheating is potentially a dire situation should we have an engine seize. Not to mention all the ramifications and shortfalls of Nissan's own warranty as it defaults to Nissan's own engineering miscalculation. Again, the distinction that the National Highway Traffic Safety Administration (NHTSA) will be reviewing and placing under consideration is the safety aspect.

Others have mentioned that Nissan did not act on an emissions, and tire wear issues. Why? Neither qualified as a life/safety issue. One was an environmental issue, and the other Nissan easily avoided as tire wear can be related to many aspects; this was not a matter of immediate tire blowout, but accelerated tire wear. Life/safety issues are pressing, and viewed seriously by the government (just when you thought the government wasn't worth a damn). The NHTSA has the power to require Nissan to issue a national recall versus a Technical Service Bulletin (TSB). A recall should be the goal as a TSB is at the discretion of the Service Department. All this can change if Nissan voluntarily does the right act and willingly rectifies this issue.

Life/Safety, and When It Matters:

Not all situations will bring about a recall as Nissan has intentionally implemented safeguards through Limp Mode when engine temperatures reach a certain point. Fine, if you are in slow moving traffic or have the opportunity to pullover. Disastrous in given situations such as climbing a grade in hot weather on a two-lane trucking route with no shoulder on the fast lane, and vehicles following tightly in the fast lane trying pass slow-moving vehicles in the slow lane—engagement of the Limp Mode could mean being rear-ended. My wife chose not to travel with our Z as we encounter this exact scenario on the way to visit her parents; even worse on the return route home. Nissan does not want nor need a headline reading, "Nissan Sports Car Causes Multiple Car Pile-Up on Interstate." This will not bode well with sales, forbid someone become seriously or fatally injured. Very bad press all around for Nissan if the resultant is because a 370Z suddenly decided to lower its speed causing the accident.

Specify to each brand oil and it composition is the temperature point that its lubricating properties breakdown. Oil from this point forth no longer lubricates the engine efficiently and necessitates an oil change. Failing to do so prematurely shortens the life of your engine. Period. Engine failure is not out of the question when something is left-out of the equation in keeping your engine running properly. Engine failure does not send you a convenient appointment reminder when it will occur and has the propensity of happening at the worst possible time. Driving on the road at highway speeds is not a good time for an engine failure when other drivers are also traveling at similar speeds. Engine failure means the loss of control of the vehicle as steering systems, braking systems, and the actual movement of the vehicle are seriously compromised. Life/safety issue? Uh, yes!

People Ask Questions, Rolling Billboards, Those PITA Surveys

Face it, driving around a 370Z with it just being released prompts questions from other interested parties and the last thing Nissan wants is an owner talking to a potential owner about the issues with the 370Z—specifically engine related problems. Driving a shiny, well-maintained 370Z is a rolling billboard for Nissan marketing, and they know it. Plus, it's free for Nissan! Keeping the enthusiast happy promotes repeat buyers, and additional free advertisement.

For those who have purchased a 370Z you know how quickly the surveys arrived in the mail…a bit too quickly for any meaningful statistical data. These surveys do not care about Nissan, other than the subscription Nissan might have with them, and these surveyors do not care about you the owner (or they would send more than a lousy buck to fill-out material they make money on selling). I feel that they are detrimental to resale values, and play on the euphoria of buying a new vehicle. A survey coming in the mail six months from the purchase makes better sense if you are trying to gather meaningful data. I am holding off filling-out any survey until the final resolution of this matter have been achieved.

R-E-S-P-E-C-T, find out what it means to me…

In the Japanese culture "losing face" is a serious matter; in the Japanese corporate world it is almost a sure means to being branded a "window watcher" where you are assigned menial tasks, and mostly spend you days reading the newspaper as everyone knows your new position. This situation might not lead to such a position for a Japanese Nissan employee(s), but it's pretty close. It is important that we take measures of saving face for Nissan to move this forward. Unfortunately, and I have personal experience with these matters, Japan's US branch of business relies heavily on US legal counsel, and to me, this is where our problem reside. The Japanese want to do the correct measure, the US legal advice, is well…I don't even have the time to delve into this abyss. The bright spot is that the Japanese, back in Japan, have the final say, lawyer or no lawyer. The US Customer Service person you speak with does not have a final say, the dealership's Service Department personal does not have a final say—Nissan corporate has the final say. Respect in dealing with the parties in this situation will move matters better.

Document, Document, Document:

Two things need to be accomplished: 1) Calling or emailing Nissan with your legitimate issue(s) and 2) filing a legitimate complaint with the NHTSA. Please, under no circumstance file any complaint that is misleading, albeit ever so slightly, is unacceptable.

Another helpful call will be to the Sales Manger of the Nissan dealership where you purchased your 370Z to telling them that you are concerned with your purchase owed to overheating issues. This way sales will know about it. If you take your 370Z in for servicing, and you are having, or very close to having, an overheating issue, get in on record when they write-up your service order. This measure is important regarding your rights as consumer and enacting the Lemon Law. To review your State's Lemon Law simply do a web search and find your State's actual law (typical the link with end a ".gov"). There are many websites that have all the States listed, but this is no guarantee they have current laws so do an individual search. An example: California Motor Vehicle Warranty and Lemon Law

When you file a concern with Nissan they give you a file number, the name, and telephone number of the person you are speaking with. Be prepared to tell them the mileage on your 370Z. Log all the dates, times, and contacts you speak with at Nissan Customer Service.

The Scheme of Things:

Speaking with Customer Service is merely recording your issue as the Customer Service representative has no authority other than to collect information and guide you within the intentional rote constraints. Escalating your compliant to a Customer Service Manager will yield the same results.

Results will come from either writing Nissan Japan directly, where it be noticed, and a report started internally; a NHTSA filing. Data from the States will eventually make its way to Japan, but writing Japan directly will cause corporate to ask questions of its US operations. There's no stopping the ball when that happens.

What to Expect When Nissan Corrects the Situation:

This is the proverbial PITA as it will mean a service department removing the front bumper fascia, along with other parts, and then installing the oil cooler. This can also mean missing fasteners, paint scratches, missing parts, or (in the best case scenario) a perfect retrofit. Either way I will probably be removing the front end after the retrofit and going over everything in detail to see it all has been performed correctly. All is contingent upon Nissan doing the right thing in this matter's resolution.

Closing Note (for now):

It is unimportant whether you use your 370Z for track and have added aftermarket parts as a national recall requires Nissan to remedy the issue. Besides, although Nissan will never say it publicly (remember that US legal counsel I mentioned above) but enthusiasts are the bread and butter of the Z sales.

If works both ways here…Nissan manufactures an automobile we are interested in, and we support Nissan for its decision through purchasing this automobile. Keeping a strong relationship versus an adversarial relationship is better for both parties.

I have to say that lately when people have been asking me about the Z (a lot of people!) I tell them about how fun of a car it is to drive, but they should NOT buy one because there is a serious oil overheating problem that has gone totally unaddressed by Nissan. Then I go on to talk about how they supplied all the cars to the review mags with oil coolers (implying they knew oil temps were getting too high) then left them off of the factory production cars. They look at me and say "ohhhh." That typically ends that conversation, as it should.
