Reliability report · 2017 Chevrolet Malibu · Updated July 2026

Same engine risks as 2016 with fewer recalls — the covered 1.5T is the one to find.

2017 is mechanically a twin of 2016: the 1.5-liter turbo's pre-ignition piston condition and the 'Engine Power Reduced' accelerator-pedal sensor are the two patterns that matter, and both are covered — a Customer Support Program (a CSP, GM's quiet extended-warranty-style coverage) replaces pistons on 2016–2017 cars, and a Special Coverage repairs the pedal-sensor connection on 2016–2018 cars. The brake vacuum pump's hard-pedal failure is here too.

The good news relative to 2016 is a shorter recall list — the passenger-air-bag, fuel-pump, seat-belt, and a rear-side-air-bag campaign, all free. The move is the same: find a 2017 whose 1.5T programs and recalls were actually claimed, or expect to gamble on a several-thousand-dollar engine if the piston condition was left to run.

Canary status

Squawking

What that means: The second ninth-gen year carries the same two expensive 1.5-liter-turbo patterns as 2016 — pre-ignition piston damage and the reduced-power pedal sensor — but with four recalls instead of nine. The programs that make it safe to buy are the pre-ignition Customer Support Program and the accelerator-pedal Special Coverage, both of which reach 2017.

1.5L turbo pre-ignition — melted pistons (CSP for 2016–2017)

major
  • 1.5L turbo I4

The 2017's headline engine risk. The 1.5-liter LFV turbo can suffer a pre-ignition condition that makes it run rough, misfire, and consume oil, and — untreated — damages the pistons. GM's Customer Support Program (a CSP, its extended-warranty-style coverage) replaces pistons on affected 2016–2017 Malibus. Community and mechanic sources describe the same progression: it starts as oil consumption and a rough-running engine and ends, if ignored, as melted pistons that contaminate the oiling system. If the CSP wasn't done and the engine burns oil or runs rough, price in a full engine.

This is a 1.5L turbo I4 problem. The 2.0L turbo I4 and Hybrid (eCVT) don’t share it.

'Engine Power Reduced' — accelerator-pedal sensor (Special Coverage)major

  • 1.5L turbo I4

The loudest cluster in the file, same as 2016: an interrupted electrical connection to an accelerator-pedal-position sensor drops the car into reduced-power limp mode — cut acceleration and torque, Check Engine Light, an 'Engine Power is Reduced' message, and code P2138. GM's Special Coverage (a free extended repair program) covers the 2016–2018 Malibu for exactly this. Confirm it was completed; treat a reduced-power episode on the test drive as this condition until proven otherwise.

Brake vacuum pump failure — hard pedalmajor

The brake vacuum pump can fail (code P1101), leaving a rock-hard, unassisted pedal that makes the car hard to stop; a related bulletin covers a weak-booster-vacuum condition (code P050F). GM's preliminary-information bulletin names 'increased brake pedal effort due to vacuum pump failure' across these years. On the 1.5-liter turbo, owners also report debris from the failing pump reaching the camshaft. A firm, boosted-feel-free pedal on a test drive is a serious flag.

Shift-to-Park false message and auto-stop stallsmoderate

The GM-family 'Shift to Park' message can appear with the car already in park, sometimes blocking shutdown and draining the 12-volt battery, and the auto-stop system can stall when it should restart. No safety recall and no clean permanent fix — a car that repeatedly won't shut off or stalls out of auto-stop is showing a known headache.

Center high-mounted stop-lamp water leak (Special Coverage)minor

A Special Coverage covers a water leak through the center high-mounted stop lamp on 2016–2017 Malibus; dealers repair it with a lamp kit of insulators and fasteners, free. It matters most on a hybrid, where water can reach the high-voltage battery in the trunk. Check the trunk and rear parcel shelf for staining and ask whether the program was completed.

Sources: NHTSA manufacturer communications (2016–2017 pre-ignition CSP; 2016–2018 accelerator-pedal Special Coverage; stop-lamp Special Coverage; vacuum-pump/booster bulletins; recall documents)

2016 and 2017 models with the 1.5-liter engine are prone to pre-ignition that can cause piston damage and, as a result, loss of compression and engine oil consumption.
