2017 Chevrolet Trax: check engine light

Filed Sep 22, 2026 · Electrical, Engine · FL

I am filing this formal complaint regarding a severe, recurring, and catastrophic electrical and vehicle control system failure in my 2017 Chevrolet Trax. On multiple occasions while driving at highway speeds (70+ mph), the vehicle experienced simultaneous loss of critical safety and control systems—including power steering, traction control, and instrumentation displays—plunging the vehicle into a severe "limp mode." This sudden and unpredictable loss of control at high speeds presents an extreme safety hazard to myself, my passengers, and other drivers. CHRONOLOGY OF EVENTS & DEFECT PATTERN 1. Initial Intermittent Failures (Past 12 Months): The traction control light began activating intermittently and randomly without cause. A dealership reset temporarily cleared the issue, but it later returned. 2. Sensor System Failures (Approx. March 2026): All four Tire Pressure Monitoring System (TPMS) sensors began failing sequentially until complete loss of tire pressure telemetry across the dashboard. 3. First Major Highway Power Failure (July 2026): While traveling at 70 mph on the highway, the vehicle suffered a complete system collapse: Simultaneous loss of Power Steering (requiring extreme manual steering effort at high speeds) and Traction Control. Check Engine Light illuminated. Instrumental cluster failed completely: digital tachometer and speedometer registered 0 RPM and 0 MPH while actively traveling at speed. Upon pulling off the highway, the vehicle entered a limp state, restricting speed to under 10 mph. After shutting off the engine, the vehicle's dashboard screen went entirely black/unresponsive upon re-attempting ignition. After sitting stationary for an extended period, the vehicle restarted, though the Check Engine Light remained illuminated. There is more to this but I ran out of characters to type it all so I'll include it with the files below. Thank you.

Turbocharger on my 2017 Chevy Trax failed at approximately 80,000 miles. Took it in for repair and they reported that upon examination a 299 code appeared and the turbocharger needed to be replaced. Check engines light also came on.

Vehicle engine light came on XXX and was driven immediately to Auto Zone to check the code. The code showed P0299. The vehicle was then taken 2 miles home and parked. It was towed to Lake Chevrolet in [XXX] on XXX to prevent any engine damage from occurring due to the failed turbo. Upon Lake's inspection they claim the manifold and valve cover gasket must be replaced. We agreed to that, and asked about an oil change as everything we read said that was mandatory with work like this. Was told the technician didn't suggest it but they would do it at our request for an additional charge. After they confirmed the turbo was bad and well as the items above we agreed to the repairs and they said the vehicle would be ready the next day. We called again at the end of the next day and they said the repairs were made and they were going to drive the vehicle to make sure all was well. The next call we received was the service advisor stating we need a new engine as after they drove it white smoke was coming from the exhaust and they now found a cracked piston. The vehicle was not blowing out white smoke when they received, it also passed emissions on 4/14/26. We also asked for all technician notes, diagnostics, etc. which they will not provide us unless we come in and get the non running vehicle and pay the 983.00 invoice. We would have to have the vehicle towed from their lot as it can't be driven since their repairs. We contacted GM and spoke with "Tamar" multiple times with no resolution. Service manager claims GM will pay 1,500.00 towards a 9,000.00 new engine. This engine damage is consequential damage of the turbo failure which the dealership is denying. GM and Lake Chevrolet are refusing to honor special coverage XXX for the resulting catastrophic damage. Dealership also refusing to provide documentation requested in attached letter. We seem to be expected to take their word for all of this. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My check engine light keeps staying on I go and have it scanned and they tell me it's sensors so each time I change my sensors the check engine light comes back on again, not sure how many sensor is that I have to keep changing in order for my check engine light to go off and I'm not sure if there's a problem with the diagnose of the engine light so I wanted to know if other people are having the same problem as me I can't keep paying to change all these sensors and each time I have it scan it shows up some more so I'm thinking it must be misdiagnosing something that's why I'm checking if there was any other complaints or recalls on this thank you very much

When driving, speedometer/RPM dial both go to 0. The “Service Stabilitrak” message comes on followed by the “Service Power Steering, Drive With Care” message. The check engine light will also sometimes appear. The transmission is also affected (jerking when changing gears, inability to accelerate properly, revving). Power steering goes in and out. Car doesn’t feel safe to drive while it’s happening. No triggers or commonalities known. Car goes back to normal when left off and turned back on. Code U0073 "Control Module Communication Bus 'A' Off” appeared with at home OBD2 scanner.

Where to begin. I bought the vehicle brand new with 29 miles on it in April of 2017, January of 2019 I started having issues. My check engine light kept coming on and it affected my gas mileage and speed. I had stopped at a chevy dealership in Forest Lake Minnesota and had them scan the vehicle to see what was going on and made an appointment to bring it back in for a full diagnostics. I get there and they asked me if I had another vehicle with me because it would take about a week of it being there. First off, I hadn't agreed to anything yet, I still did not even know what was wrong with it yet. They ended up doing what they said was a full diagnostic on the vehicle (which cost me almost $200) came back to me and started off by telling me that I bought a "warm weather" vehicle and it in fact was my turbo that was going out. They stated that what was happening was it would freeze and what needed to be done was some sort of heating element needed to be installed, and this was going to cost me $2500 plus labor. I was out of warranty but still had my drivetrain warranty ( at this time I had forgotten I had purchased the extended warranty) I was told it wouldn't cover it. I was irate and left, was contacted a few days later by my normal dealership to replace a valve (special service) had that done, found out that the real issue was an oil and air leak. Now to fast forward to 2021- I fixed the oil and air leak 3 more times before replacing the intake cover from plastic to aluminum. Engine is still leaking oil like crazy though. That is only one piece of my issues, I keep getting a code (since 2021) P0420 which reads that it's my catalysts- since I was out of warranty I needed to wait until I could afford to do this, plus we needed to figure out which or both.. then I received the letter stating that there are issues with the turbo. Of course, I am out of warranty, now over 120k and the POS is costing me a fortune! If I had more space I could go on with my issues.

My Check engine light came on at about 46,000 miles. The mechanic showed me that the oil was burned at looked like chips of metal. He said that the Turbo Charger was cracked also. He replaced everything and flushed the system clean. He video taped the whole repair process. Now, 8,000 miles later, the Check Engine light is back on and the very same problem has repeated itself. I looked on the internet and found HUNDREDS of Blogs with THOUSANDS of Consumers with the same problem. All of them state that the Turbo Charger cracks, leaks into the coolant, over-heats the engine and burns up the oil. They all state that the repair is about $3,000.00. Some are on their 3rd and 4th go-around with this problem. They state that Chevrolet does NOT respond. I, personally, contacted the dealership that sold me my care and reported the problem. I was told that mine was an isolated incident and then they tried to sell me another car. Here is ONLY ONE BLOG with all the consumers' complaints about this ONE MATTER: [XXX] I paid around $35,000.00 for this car at the time of purchase. I paid it off early. You can tell by the low mileage that I do not drive my automobile hard. I keep it well maintained. At 50,000 miles, it cannot be driven until I invest another $3,000.00 in repairs....that I just paid 8,000 miles ago for the the same repeating problem. I need Chevrolet to do one of three things: 1) Resolve the ROOT problem that keeps causing this ongoing problem and fix my car PERMANENTLY of this problem at NO CHARGE; 2) Give me a different model car that has 50,000 miles as an exchange; 3) Refund 2/3 of my money so that I can get a different vehicle. They have left me with no automobile to drive. They act like I am too stupid to understand that the problem lies with them (probably because I am female). They try to convince me to spend yet another 35,000 to 40,000 dollars on a different new car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2017 Chevrolet Trax mileage 35,703 November 20, 2022 ( second incident)while driving 50 mph on a highway, I lost power steering, acceleration, and dashboard instruments( speedometer & tach) failed. Dashboard message advised of loss of power steering. I was able to drive about one mile before I could safely pull to the side of the road and after stopping the issue resolved itself but check engine light came on but turned off within a 24 hour period. Later found out my son had experienced the same issue with my car one month earlier. December 6 th- Took it to dealer who could not replicate the problem and was unable to provide explanation or solution. This was a frightening safety issue- luckily there was not a lot of traffic when the problem occurred. I am very concerned about driving this car and having this happen again.
